Certification of alternative aviation fuels and blend components  

SciTech Connect (OSTI)

Aviation turbine engine fuel specifications are governed by ASTM International, formerly known as the American Society for Testing and Materials (ASTM) International, and the British Ministry of Defence (MOD). ASTM D1655 Standard Specification for Aviation Turbine Fuels and MOD Defence Standard 91-91 are the guiding specifications for this fuel throughout most of the world. Both of these documents rely heavily on the vast amount of experience in production and use of turbine engine fuels from conventional sources, such as crude oil, natural gas condensates, heavy oil, shale oil, and oil sands. Turbine engine fuel derived from these resources and meeting the above specifications has properties that are generally considered acceptable for fuels to be used in turbine engines. Alternative and synthetic fuel components are approved for use to blend with conventional turbine engine fuels after considerable testing. ASTM has established a specification for fuels containing synthesized hydrocarbons under D7566, and the MOD has included additional requirements for fuels containing synthetic components under Annex D of DS91-91. New turbine engine fuel additives and blend components need to be evaluated using ASTM D4054, Standard Practice for Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives. This paper discusses these specifications and testing requirements in light of recent literature claiming that some biomass-derived blend components, which have been used to blend in conventional aviation fuel, meet the requirements for aviation turbine fuels as specified by ASTM and the MOD. The 'Table 1' requirements listed in both D1655 and DS91-91 are predicated on the assumption that the feedstocks used to make fuels meeting these requirements are from approved sources. Recent papers have implied that commercial jet fuel can be blended with renewable components that are not hydrocarbons (such as fatty acid methyl esters). These are not allowed blend components for turbine engine fuels as discussed in this paper.

The relationship between the thermoplastic behavior of blends and their component coals  

SciTech Connect (OSTI)

The thermoplastic behaviors of a number of coking coal blends were measured using proton magnetic resonance thermal analysis (PMRTA) to determine to what extent they were affected by interactions between the component coals. Most blends showed evidence that at temperatures near their temperatures of maximum fluidity the extent to which they fused was different to that expected if the coals did not interact. Only blends of coking coals of different rank fused to a greater extent than expected in the absence of interactions. Semi-anthracite, low rank coals and charcoal reduced the extent of fusion of coking coals to values below those expected if they were acting as inert diluents. These interactions are interpreted as being mediated by transfer of volatile material between the coals on heating.

Powertrain Component Inspection from Mid-Level Blends Vehicle Aging Study  

SciTech Connect (OSTI)

The Energy Independence and Security Act of 2007 calls on the nation to significantly increase its use of renewable fuels to meet its transportation energy needs. The law expands the renewable fuel standard to require use of 36 billion gallons of renewable fuel by 2022. Given that ethanol is the most widely used renewable fuel in the U.S. market, ethanol will likely make up a significant portion of the 36-billion-gallon requirement. The vast majority of ethanol used in the United States is blended with gasoline to create E10-gasoline with up to 10% ethanol. The remaining ethanol is sold in the form of E85 - a gasoline blend with as much as 85% ethanol that can only be used in flexible-fuel vehicles (FFVs). Consumption of E85 is at present limited by both the size of the FFV fleet and the number of E85 fueling stations. Gasoline consumption in the United States is currently about 140 billion gallons per year; thus the maximum use of ethanol as E10 is only about 14 billion gallons. While the U.S. Department of Energy (DOE) remains committed to expanding the E85 infrastructure, that market represented less than 1% of the ethanol consumed in 2010 and will not be able to absorb projected volumes of ethanol in the near term. Because of these factors, DOE and others have been assessing the viability of using mid-level ethanol blends (E15 or E20) as a way to accommodate growing volumes of ethanol. The DOE Mid-Level Ethanol Blends Test Program has been under way since 2007, supported jointly by the Office of the Biomass Program and the Vehicle Technologies Program. One of the larger projects, the Catalyst Durability Study, or Vehicle Aging Study, will be completed early in calendar year 2011. The following report describes a subproject of the Vehicle Aging Study in which powertrain components from 18 of the vehicles were examined at Southwest Research Institute under contract to Oak Ridge National Laboratory (ORNL).

Pilot plant assessment of blend properties and their impact on critical power plant components  

SciTech Connect (OSTI)

A series of tests were performed to determine the effects of blending eastern bituminous coals with western subbituminous coals on utility boiler operation. Relative to the baseline bituminous coal, the testing reported here indicated that there were significant impacts to boiler performance due to the blending of the eastern and western coals. Results indicated that fuel blending can be used to adequately control flue gas emissions of both SO{sub 2} and NO{sub x} at the expense of reduced milling efficiency, increased sootblowing in the high-temperature and low-temperature regions of the boiler and, to a lesser extent, decreased collection efficiency for an electrostatic precipitator. The higher reactivity of the subbituminous coal increased the overall combustion efficiency, which may tend to decrease the impact of milling efficiency losses. The extent of these impacts was directly related to the percentage of subbituminous coal in the blends. At the lowest blend ratios of subbituminous coal, the impacts were greatly reduced.

Truck loading rack blending  

SciTech Connect (OSTI)

Blending, the combining of two or more components to make a single product, has become widely used in most loading rack applications. Blending should not be confused with additive injection, which is the injection of very small doses of enhancers, detergents and dyes into a product stream. Changes in the environmental protection laws in the early 90`s have put increasing demands on marketing terminals with regards to reformulated fuels and environmental protection concerns. As a result of these new mandates, terminals have turned to blending at the loading rack as an economical and convenient means in meeting these new requirements. This paper will discuss some of these mandates and how loading rack blending is used for different applications. Various types of blending will also be discussed along with considerations for each method.

Droplet combustion studies of hydrocarbon-monopropellant blends  

Science Journals Connector (OSTI)

Abstract An experimental investigation was conducted to characterize the monopropellant droplet combustion of pure and blended isopropyl nitrate (IPN), suspended on quartz fibers in a quiescent atmosphere. The blends were prepared by mixing varying percentages by weight of IPN with less viscous n-heptane, as well as highly viscous desensitizer dibutyl sebacate (DBS). Ignition was achieved by using a heated 60 ?m Nichrome wire. The dependence of the burning rate constant of pure IPN on initial droplet diameter was investigated in the droplet size range of 0.79–1.97 mm. The blended IPN studies were carried out with initial droplet diameters of 2 and 1.5 mm for IPN-n-heptane and IPN-DBS blends respectively, to characterize the effect of gravimetric composition. The experiments revealed a strong dependence of IPN burning rate on droplet size. The IPN-DBS blends were characterized by severe micro-explosions, further atomizing the droplet, governed by the preferential evaporation of IPN over DBS. However, micro-explosions were conspicuously absent in case of IPN-n-heptane blends due to simultaneous gasification of both components.

Interaction blending equations enhance reformulated gasoline profitability  

SciTech Connect (OSTI)

The interaction approach to gasoline blending gives refiners an accurate, simple means of re-evaluating blending equations and increasing profitability. With reformulated gasoline specifications drawing near, a detailed description of this approach, in the context of reformulated gasoline is in order. Simple mathematics compute blending values from interaction equations and interaction coefficients between mixtures. A timely example of such interactions is: blending a mixture of catalytically cracked gasoline plus light straight run (LSR) from one tank with alkylate plus reformate from another. This paper discusses blending equations, using interactions, mixture interactions, other blending problems, and obtaining equations.

Radiation effects on polypropylene/polybutylene blends  

SciTech Connect (OSTI)

Polymer blends of polypropylene and polybutylene have been found to exhibit substantial maintenance of structural integrity after exposure to ionizing radiation. This radiation resistance has been found to be related to processing conditions and the resulting morphology of the blend. This article discusses (a) the processing conditions and the resulting mechanical properties after irradiation and (b) the role of morphology in this unexpected blend property.

Degradation studies on acid–base blends for both LT and intermediate T fuel cells  

Science Journals Connector (OSTI)

Abstract In this study the ex-situ and in-situ behavior of acid–base blend membranes from sulfonated polyethersulfone and a partially fluorinated sulfonated polymer (prepared by condensation of decafluorobipenyl with bisphenol AF, followed by sulfonation of the obtained polymer) and two different polybenzmidazoles (F6-PBI and PBIOO®) was investigated. Two types of acid–base blend membranes from the abovementioned polymers were prepared and characterized: acid–base blend membranes with a molar excess of acidic blend component for low-T H2 fuel cells (LT-FC) where the proton conductivity is overtaken by the sulfonic acid groups, and blend membranes comprising a molar excess of basic blend component which were subsequently doped with phosphoric acid for the usage in intermediate-T H2 fuel cells (IT-FC) where the network of phosphoric acid molecules in the membrane provides the proton conduction. For elucidation of the radical stability of the membranes, the membranes were subjected to Fenton's Reagent and were operated in a H2-PEMFC. After these tests, the membranes were investigated via SEC for molecular weight degradation. As a result, correlations could be found between degradation of the blend membranes in the fuel cell and after Fenton's test. Moreover, at IT-FC membranes, a correlation could be found between doping degree and fuel cell performance which are discussed in this paper. One of the membranes, a H3PO4-doped base-excess membrane from sPSU and PBIOO showed an excellent performance in an IT-FC at 180 °C of 0.85 A/cm2@0.5 V without pressurization of the reactant gases.

WI Biodiesel Blending Progream Final Report  

SciTech Connect (OSTI)

The Wisconsin State Energy Office�¢����s (SEO) primary mission is to implement cost�¢���effective, reliable, balanced, and environmentally�¢���friendly clean energy projects. To support this mission the Wisconsin Biodiesel Blending Program was created to financially support the installation infrastructure necessary to directly sustain biodiesel blending and distribution at petroleum terminal facilities throughout Wisconsin. The SEO secured a federal directed award of $600,000 over 2.25 years. With these funds, the SEO supported the construction of inline biodiesel blending facilities at two petroleum terminals in Wisconsin. The Federal funding provided through the state provided a little less than half of the necessary investment to construct the terminals, with the balance put forth by the partners. Wisconsin is now home to two new biodiesel blending terminals. Fusion Renewables on Jones Island (in the City of Milwaukee) will offer a B100 blend to both bulk and retail customers. CITGO is currently providing a B5 blend to all customers at their Granville, WI terminal north of the City of Milwaukee.

Influence of coal thermoplastic properties on coking pressure generation: Part 2 – A study of binary coal blends and specific additives  

Science Journals Connector (OSTI)

A number of coal blends and pitch/coal blends were evaluated using rheometry, thermogravimetric analysis and microscopy to confirm and further elucidate the coking pressure mechanism previously proposed by Duffy et al. (2007) [1]. We confirm that blending a low rank, high fluidity, low coking pressure coal, with a high rank, low fluidity, high coking pressure coal can significantly reduce the coking pressure associated with the latter. Interestingly, blending does not necessarily result in a fluidity that is midway between that of the two coals; sometimes the fluidity of the blend is less than that of the low fluidity coal, especially when the coals are significantly different in rank. This occurs because the increase in complex viscosity (?*) through resolidification of the low rank, high fluidity coal counteracts the reduction in ?* resulting from softening of the high rank, low fluidity coal. It has also been confirmed that the ?* of the resultant blend can be estimated from the ?* of each component coal using a logarithmic additivity rule commonly employed for polymer blends. Polarised light microscopy has indicated that the degree of mixing between coals of different rank is minimal, with fusion restricted to the particle surface. It is therefore inappropriate to think of such a coal blend in the same way as a single coal, since each component coal behaves relatively independently. This limited fusion is important for understanding the coking pressure mechanism for blends. It is proposed here that the lower rank coal, which softens at lower temperature, is able to expand into the interparticle voids between the high rank coal that is yet to soften, and these voids can create channels for volatiles to traverse. Then, and importantly, when the high rank coal begins to expand, the pore structure developed in the resolidified structures of the low rank coal can facilitate removal of volatiles, while the resolidified material may also act as a suitable sorbent for volatile matter. This is considered to be the primary mechanism by which coal blending is able to alleviate coking pressure, and applies to addition of inert material also. Addition of a coal tar pitch was found to increase fluidity but also to extend the thermoplastic range to lower temperatures. This caused an increase in the swelling range, which was accompanied by a long plateau in ?*, a feature which has previously been observed for certain high fluidity, high pressure coals. Elasticity and ?* at the onset of expansion were also higher for both the pitch impregnated coals and the high pressure blends, which supports previous findings for singly charged high pressure coals, and confirms the potential use of such criteria for identifying potentially dangerous coals/blends.

Concentration fluctuations in miscible polymer blends: Influence of temperature and chain rigidity  

SciTech Connect (OSTI)

In contrast to binary mixtures of small molecule fluids, homogeneous polymer blends exhibit relatively large concentration fluctuations that can strongly affect the transport properties of these complex fluids over wide ranges of temperatures and compositions. The spatial scale and intensity of these compositional fluctuations are studied by applying Kirkwood-Buff theory to model blends of linear semiflexible polymer chains with upper critical solution temperatures. The requisite quantities for determining the Kirkwood-Buff integrals are generated from the lattice cluster theory for the thermodynamics of the blend and from the generalization of the random phase approximation to compressible polymer mixtures. We explore how the scale and intensity of composition fluctuations in binary blends vary with the reduced temperature ? ? (T ? T{sub c})/T (where T{sub c} is the critical temperature) and with the asymmetry in the rigidities of the components. Knowledge of these variations is crucial for understanding the dynamics of materials fabricated from polymer blends, and evidence supporting these expectations is briefly discussed.

Conformational properties of blends of cyclic and linear polymer melts  

Science Journals Connector (OSTI)

An adapted version of the annealing algorithm to identify primitive paths of a melt of ring polymers is presented. This algorithm ensures that the primitive path length becomes zero for nonconcatenated rings, and that no entanglements are observed. The bond-fluctuation model was used to simulate ring-linear blends with N=150 and 300 monomers. The primitive path length and the average number of entanglements of the linear component were found to be independent of the blend composition. In contrast, the primitive path length and the average number of entanglements on a ring molecule increased approximately linearly with the fraction of linear chains, and for large N, they approached values comparable with linear chains. Threading of ring molecules by linear chains, and ring-ring interactions were observed only in the presence of linear chains. It is conjectured that for large N, these latter interactions facilitate the formation of a percolating entangled network, thereby resulting in a disproportionate retardation of the dynamical processes.

HEU to LEU conversion and blending facility: Metal blending alternative to produce LEU oxide for disposal  

SciTech Connect (OSTI)

US DOE is examining options for disposing of surplus weapons-usable fissile materials and storage of all weapons-usable fissile materials. The nuclear material is converted to a form more proliferation- resistant than the original form. Blending HEU (highly enriched uranium) with less-enriched uranium to form LEU has been proposed as a disposition option. Five technologies are being assessed for blending HEU. This document provides data to be used in environmental impact analysis for the HEU-LEU disposition option that uses metal blending with an oxide waste product. It is divided into: mission and assumptions, conversion and blending facility descriptions, process descriptions and requirements, resource needs, employment needs, waste and emissions from plant, hazards discussion, and intersite transportation.

BIODIESEL BLENDS IN SPACE HEATING EQUIPMENT.  

SciTech Connect (OSTI)

Biodiesel is a diesel-like fuel that is derived from processing vegetable oils from various sources, such as soy oil, rapeseed or canola oil, and also waste vegetable oils resulting from cooking use. Brookhaven National laboratory initiated an evaluation of the performance of blends of biodiesel and home heating oil in space heating applications under the sponsorship of the Department of Energy (DOE) through the National Renewable Energy Laboratory (NREL). This report is a result of this work performed in the laboratory. A number of blends of varying amounts of a biodiesel in home heating fuel were tested in both a residential heating system and a commercial size boiler. The results demonstrate that blends of biodiesel and heating oil can be used with few or no modifications to the equipment or operating practices in space heating. The results also showed that there were environmental benefits from the biodiesel addition in terms of reductions in smoke and in Nitrogen Oxides (NOx). The latter result was particularly surprising and of course welcome, in view of the previous results in diesel engines where no changes had been seen. Residential size combustion equipment is presently not subject to NOx regulation. If reductions in NOx similar to those observed here hold up in larger size (commercial and industrial) boilers, a significant increase in the use of biodiesel-like fuel blends could become possible.

Meet changing fuel requirements with online blend optimization  

SciTech Connect (OSTI)

Compania Espanola de Petroleos (CEPSA) embarked on an overall refinery automation program, with state-of-the-art gasoline blending being one of the highest priorities. The result of this effort is a sophisticated computerized gasoline blending system using offline LPs for initial optimal recipe calculation, an online LP for real-time blend recipe reformulation using online analyzers for blending model adjustment, complete automation of blending sequence startup and shutdown, generation of end of blend quality performance reports, and real-time integration between lab, tank gauging, plant information, and blending systems. The entry of Spain in the EEC brought with it the need to quickly adapt to the requirements of an openly competitive marketplace emphasizing no lead, oxygenated, high performance gasolines and ISO 9000 quality standards. The blending system allowed CEPSA to produce lowest cost, minimum giveaway gasolines, while having the flexibility to produce a wide variety of modern gasolines serving the Western European market. The paper describes the blender architecture, optimizer linear programming, man machine interface, and results from the blending system.

Purification Testing for HEU Blend Program  

SciTech Connect (OSTI)

The Savannah River Site (SRS) is working to dispose of the inventory of enriched uranium (EU) formerly used to make fuel for production reactors. The Tennessee Valley Authority (TVA) has agreed to take the material after blending the EU with either natural or depleted uranium to give a {sup 235}U concentration of 4.8 percent low-enriched uranium will be fabricated by a vendor into reactor fuel for use in TVA reactors. SRS prefers to blend the EU with existing depleted uranium (DU) solutions, however, the impurity concentrations in the DU and EU are so high that the blended material may not meet specifications agreed to with TVA. The principal non-radioactive impurities of concern are carbon, iron, phosphorus and sulfur. Neptunium and plutonium contamination levels are about 40 times greater than the desired specification. Tests of solvent extraction and fuel preparation with solutions of SRS uranium demonstrate that the UO{sub 2} prepared from these solutions will meet specifications for Fe, P and S, but may not meet the specifications for carbon. The reasons for carbon remaining in the oxide at such high levels is not fully understood, but may be overcome either by treatment of the solutions with activated carbon or heating the UO{sub 3} in air for a longer time during the calcination step of fuel preparation.Calculations of the expected removal of Np and Pu from the solutions show that the specification cannot be met with a single cycle of solvent extraction. The only way to ensure meeting the specification is dilution with natural U which contains no Np or Pu. Estimations of the decontamination from fission products and daughter products in the decay chains for the U isotopes show that the specification of 110 MEV Bq/g U can be met as long as the activities of the daughters of U- 235 and U-238 are excluded from the specification.

Synthesis of grafted polyamide/polyglutarimide blends  

SciTech Connect (OSTI)

Polyglutarimides are high Tg thermoplastics, prepared by a reactive extrusion process involving polymethylmethacrylate and primary amines in a plasticating extruder at high pressures and temperatures. The resulting polymers can be synthesized with various levels of carboxylic acid and/or anhydride functionality as part of the polyglutarimide polymer. In a recent discovery, these polymers can be grafted to polyamides in a highly efficient manner by means of a reactive extrusion process. This talk will discuss the synthesis of these blends and techniques for their analysis. Partial fractionation, and spectroscopic analysis of these materials was used to monitor the reaction. The effects of extrusion temperature and catalyst level will be presented.

Phase identification and interfacial transitions in ternary polymer blends by ToF-SIMS  

Science Journals Connector (OSTI)

Abstract Phase identification and the study of the interphase region in multi-component polymer blends with a chemically similar structure using conventional techniques is a challenge. In this work, the detailed morphological analysis of such systems is examined. A ternary blend comprised of poly butylene succinate (PBS); poly lactic acid (PLA); and polycaprolactone (PCL) with a partial wetting morphology is carefully selected since all three components are polyesters with low interfacial tensions. It will be shown that a novel technique by applying multivariate analysis (MVA) on time-of-flight secondary ion mass spectrometry (ToF-SIMS) data can effectively identify the complex phase structure, especially in blends with chemically similar components. Furthermore, for the first time for such systems, this technique provides detailed information about interfacial thicknesses and transitions. By employing the principal component analysis (PCA) method on the ToF-SIMS data of pure polymers, specific peaks with a certain molecular ion mass related to each polymer are determined. Using overlaid mappings on the surface of the blend by ToF-SIMS and selected ion masses to identify each polymer results in the differentiation of the various phases represented as a morphological image. In a second step, the multivariate curve resolution (MCR) method is used as a “self modeling curve resolution” for the recovery of pure components from a multi-component mixture when little or no prior information is available. Total pseudo-color RGB images of PBS/PLA/PCL show that PLA droplets unambiguously partially wet the PBS and PCL phases. Since each pixel from the analysis in the high lateral resolution image represents a 200 nm diameter, the interfacial transitions can also be studied for both PLA/PBS and PLA/PCL interfaces. The results show the concentration variation of phases across the interfaces. A complete trace line across the two interfaces (PLA/PBS and PLA/PCL) allows for the quantitative determination of interfacial thickness for the first time for such systems.

Preparation and properties of chitosan–soybean trypsin inhibitor blend film with anti-Aspergillus flavus activity  

Science Journals Connector (OSTI)

The chitosan-based blend films were prepared from chitosan, soybean trypsin inhibitor extract (STI)/wild soybean trypsin inhibitor extract (WTI) and glycerol (Gly) solutions, the properties of which were also investigated, including thickness, mechanical property, water vapor transmission, optical transmittance, and solubility. In addition, the resulting films were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The result of SEM images showed the surface and cross-section of chitosan–STI/WTI–Gly blend film had more smooth and dense morphology than pure chitosan film, which suggested there was a better compatibility among the three components. XRD and FTIR spectra indicated that the possible interaction force among the components might be the hydrogen bonds of NH?OC and OH?OC. Furthermore, the antifungal activity against A. flavus by the prepared blend films had been investigated. The facts that the germination and growth of A. flavus were strongly inhibited by chitosan–STI/WTI–Gly film indicated the blend films might be useful as potential bio-control packaging against A. flavus during the peanuts and other cereals storage.

Blended language learning in tertiary education  

Science Journals Connector (OSTI)

This paper examines the supporting and enhancing role of technology in language learning and teaching in a higher education institution in Slovenia. Despite the fact that the vast majority of foreign language teaching is still carried out in face-to-face environments, a growing extent of foreign language teaching in a number of tertiary education institutions has moved, at least partly, online. In this paper, the development of e-learning practices in Slovenia is described first, together with the evolution of computer technologies – from multimedia to the internet – and their potential for language learning and teaching purposes. Against this background, the practical application of the Blended Language Learning (BLL) experience at the Faculty of Management Koper is discussed. The paper also addresses the changing role of teachers in blended language teaching/learning environments and analyses the opinions of students who participated in a combination of Face-to-Face (F2F) and Computer-Assisted Language Learning (CALL) courses and expressed their opinions on the BLL experience in a questionnaire.

Methylal and Methylal-Diesel Blended Fuels from Use In Compression-Ignition Engines  

SciTech Connect (OSTI)

Gas-to-liquids catalytic conversion technologies show promise for liberating stranded natural gas reserves and for achieving energy diversity worldwide. Some gas-to-liquids products are used as transportation fuels and as blendstocks for upgrading crude derived fuels. Methylal (CH{sub 3}-O-CH{sub 2}-O-CH{sub 3}) also known as dimethoxymethane or DMM, is a gas-to-liquid chemical that has been evaluated for use as a diesel fuel component. Methylal contains 42% oxygen by weight and is soluble in diesel fuel. The physical and chemical properties of neat methylal and for blends of methylal in conventional diesel fuel are presented. Methylal was found to be more volatile than diesel fuel, and special precautions for distribution and fuel tank storage are discussed. Steady state engine tests were also performed using an unmodified Cummins 85.9 turbocharged diesel engine to examine the effect of methylal blend concentration on performance and emissions. Substantial reductions of particulate matter emissions h ave been demonstrated 3r IO to 30% blends of methylal in diesel fuel. This research indicates that methylal may be an effective blendstock for diesel fuel provided design changes are made to vehicle fuel handling systems.

Morphological studies on block copolymer modified PA 6 blends  

SciTech Connect (OSTI)

Recent studies show that compounding polyamide 6 (PA 6) with a PA 6 polyether block copolymers made by reaction injection molding (RIM) or continuous anionic polymerization in a reactive extrusion process (REX) result in blends with high impact strength and high stiffness compared to conventional rubber blends. In this paper, different high impact PA 6 blends were prepared using a twin screw extruder. The different impact modifiers were an ethylene propylene copolymer, a PA PA 6 polyether block copolymer made by reaction injection molding and one made by reactive extrusion. To ensure good particle matrix bonding, the ethylene propylene copolymer was grafted with maleic anhydride (EPR-g-MA). Due to the molecular structure of the two block copolymers, a coupling agent was not necessary. The block copolymers are semi-crystalline and partially cross-linked in contrast to commonly used amorphous rubbers which are usually uncured. The combination of different analysis methods like atomic force microscopy (AFM), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) gave a detailed view in the structure of the blends. Due to the partial cross-linking, the particles of the block copolymers in the blends are not spherical like the ones of ethylene propylene copolymer. The differences in molecular structure, miscibility and grafting of the impact modifiers result in different mechanical properties and different blend morphologies.

Blending of Radioactive Salt Solutions in Million Gallon Tanks - 13002  

SciTech Connect (OSTI)

Research was completed at Savannah River National Laboratory (SRNL) to investigate processes related to the blending of radioactive, liquid waste, salt solutions in 4920 cubic meter, 25.9 meter diameter storage tanks. One process was the blending of large salt solution batches (up to 1135 - 3028 cubic meters), using submerged centrifugal pumps. A second process was the disturbance of a settled layer of solids, or sludge, on the tank bottom. And a third investigated process was the settling rate of sludge solids if suspended into slurries by the blending pump. To investigate these processes, experiments, CFD models (computational fluid dynamics), and theory were applied. Experiments were performed using simulated, non-radioactive, salt solutions referred to as supernates, and a layer of settled solids referred to as sludge. Blending experiments were performed in a 2.44 meter diameter pilot scale tank, and flow rate measurements and settling tests were performed at both pilot scale and full scale. A summary of the research is presented here to demonstrate the adage that, 'One good experiment fixes a lot of good theory'. Experimental testing was required to benchmark CFD models, or the models would have been incorrectly used. In fact, CFD safety factors were established by this research to predict full-scale blending performance. CFD models were used to determine pump design requirements, predict blending times, and cut costs several million dollars by reducing the number of required blending pumps. This research contributed to DOE missions to permanently close the remaining 47 of 51 SRS waste storage tanks. (authors)

Correlation between speciated hydrocarbon emissions and flame ionization detector response for gasoline/alcohol blends .  

SciTech Connect (OSTI)

The U.S. renewable fuel standard has made it a requirement to increase the production of ethanol and advanced biofuels to 36 billion by 2022. Ethanol will be capped at 15 billion, which leaves 21 billion to come from other sources such as butanol. Butanol has a higher energy density and lower affinity for water than ethanol. Moreover, alcohol fueled engines in general have been shown to positively affect engine-out emissions of oxides of nitrogen and carbon monoxide compared with their gasoline fueled counterparts. In light of these developments, the variety and blend levels of oxygenated constituents is likely to increase in the foreseeable future. The effect on engine-out emissions for total hydrocarbons is less clear due to the relative insensitivity of the flame ionization detector (FID) toward alcohols and aldehydes. It is well documented that hydrocarbon (HC) measurement using a conventional FID in the presence of oxygenates in the engine exhaust stream can lead to a misinterpretation of HC emissions trends for alcohol fuel blends. Characterization of the exhaust stream for all expected hydrocarbon constituents is required to accurately determine the actual concentration of unburned fuel components in the exhaust. In addition to a conventional exhaust emissions bench, this characterization requires supplementary instrumentation capable of hydrocarbon speciation and response factor independent quantification. Although required for certification testing, this sort of instrumentation is not yet widely available in engine development facilities. Therefore, an attempt is made to empirically determine FID correction factors for oxygenate fuels. Exhaust emissions of an engine fueled with several blends of gasoline and ethanol, n-butanol and iso-Butanol were characterized using both a conventional FID and a Fourier transform infrared. Based on these results, a response factor predicting the actual hydrocarbon emissions based solely on FID results as a function of alcohol type and content is presented. Finally, the correlation derived from data presented in this study is compared with equations and results found in the literature.

New government regulations on gasoline quality are making gasoline blending an increasingly important aspect of refining. The Environmental Protection Agency volatility regulations that establish maximum summertime commercial gasoline volatility levels provide that gasoline Reid Vapor Pressor starting in 1989 may not exceed 10.5, or 9.0 psi. Additionally, beginning in 1992, it may not exceed either 9.0 or 7.8 psi, depending on the area of the country and the month. This article discusses the on-line analysis of gas blending to minimize the volatile organic compounds released to the air.

The effect of wood biomass blending with pulverized coal on combustion characteristics under oxy-fuel condition  

Science Journals Connector (OSTI)

Abstract In this study, combustion from the co-firing of coal and wood biomass, and thermal characteristics such as ignition temperature, burn-out temperature, and activation energy were discussed using a thermogravimetric analyzer (TGA). We investigated the effects of biomass blending with two kinds of pulverized coal (bituminous Shenhua, and sub-bituminous Adaro) under air and oxy-fuel conditions. The coal fraction in the blended samples was set to 1, 0.8, and 0.5. The oxygen fraction in the oxidant was set to 0.21, 0.3, 0.5, and 0.8. The ignition temperature was governed by the fuel composition, particularly in the blended biomass which has a much higher content of volatile matter comparing to coal. However, the burnout temperature, which shows a strong relationship with char combustion, depended on the oxidant ingredients rather than on the fuel components. Thermal characteristics such as ignition, burnout temperature, reaction region, and heat flow were very similar between air and a 0.3 oxygen concentration under oxy-fuel conditions with Shenhua coal.

The nuclear material is converted to a form that is more proliferation-resistant than the original form. Examining options for increasing the proliferation resistance of highly enriched uranium (HEU) is part of this effort. Five technologies for blending HEU will be assessed. This document provides data to be used in the environmental impact analysis for the UNH blending HEU disposition option. Process requirements, resource needs, employment needs, waste/emissions from plant, hazards, accident scenarios, and intersite transportation are discussed.

Microstructure and Crystal-Amorphous Interphases in Melt-Miscible Semicrystalline Polymer Blends. Ph.D. Thesis  

SciTech Connect (OSTI)

Small-angle x ray scattering, differential scanning calorimetry, dielectric spectroscopy and dynamic mechanical thermal analysis were performed to study the microstructure of the semicrystalline polymers poly(etylene oxide) (PEO) and poly (epsilon-caprolactone) (PCL) as well as several melt miscible blends. Four amorphous polymers were blended with PEO: two which interact weakly with PEO poly(methyl methacrylate) (PMMA) and poly(vinyl acetate) (PVAc) and two which are considered strongly interacting due to the formation of hydrogen bonds with PEO (two random copolymers, one containing 50% styrene and 50% hydroxystyrene (50/50 ScHS) and another of ethylene with 55% methacrylic acid (EMA55)). Further, one of the weakly interacting amorphous polymers and one of the strongly interacting polymers was selected based on its relatively high T(sub g)s. The other amorphous polymers have relatively low T(sub g)s (i.e., at or below the crystallization temperature). The solid state microstructure of miscible blends containing a semicrystalline and an amorphous polymer is shown to be critically dependent on two factors: (1) the strength of interactions between the two copolymers; and (2) the mobility of the amorphous material at the crystallization temperature. The influence of interaction strength on the region of partial order at the crystal surface (the crystal-amorphous interphase) is demonstrated. The results are consistent with theoretical predictions that this region changes from pure crystallizable material to a mixture containing both the crystalizable and the amorphous components as chi becomes more favorable. In the blends which contain a high T(sub g) amorphous polymer and in those with strong intermolecular interactions, there were no observed changes in the microstructure with crystallization temperature. Apparently, in the high T(sub g) systems, the amorphous polymer is unable to escape the interlamellar zone since it has insufficient mobility.

Diesel vehicle performance on unaltered waste soybean oil blended with petroleum fuels  

Science Journals Connector (OSTI)

Interest in using unaltered vegetable oil as a fuel in diesel engines has experienced an increase due to uncertainty in the crude oil market supply and the detrimental effects petroleum fuels have on the environment. Unaltered vegetable oil blended with petroleum fuels is less expensive, uses less energy to produce and is more environmentally friendly compared to petroleum diesel or biodiesel. Here we investigate the engine performance of unaltered waste soybean oil blended with petroleum diesel and kerosene for three vehicles. Five biofuel blends ranging from 15% to 50% oil by volume were tested on a 2006 Jeep Liberty CRD, a 1999 Mercedes E300 and a 1984 Mercedes 300TD. A DynoJet 224x chassis dynamometer was used to test vehicle engine performance for horsepower and torque through a range of RPMs. Results for the Jeep showed a modest decrease in horsepower and torque compared to petroleum diesel ranging from 0.9% for the 15% oil blend to 5.0% lower for the 50% oil blend. However, a 30% oil blend showed statistically better performance (P < 0.05) compared to petroleum diesel. For the 1999 Mercedes, horsepower performance was 1.1% lower for the 15% oil blend to 6.4% lower for the 50% oil blend. Engine performance for a 30% blend was statistically the same (P < 0.05) compare to diesel. Finally, horsepower performance was 1.1% lower for the 15% oil blend to 4.7% lower for the 50% oil blend for the 1984 Mercedes. Overall, the performance on these oil blended fuels was excellent and, on average 1.1% lower than petroleum diesel for blends containing 40% or lower waste soybean oil content. The more significant decrease in power between the 40% and 50% oil blends indicates that oil content in these blended fuels should be no more than 40%.

Conversion and Blending Facility highly enriched uranium to low enriched uranium as oxide. Revision 1  

SciTech Connect (OSTI)

This Conversion and Blending Facility (CBF) will have two missions: (1) convert HEU materials into pure HEU oxide and (2) blend the pure HEU oxide with depleted and natural uranium oxide to produce an LWR grade LEU product. The primary emphasis of this blending operation will be to destroy the weapons capability of large, surplus stockpiles of HEU. The blended LEU product can only be made weapons capable again by the uranium enrichment process. To the extent practical, the chemical and isotopic concentrations of blended LEU product will be held within the specifications required for LWR fuel. Such blended LEU product will be offered to the United States Enrichment Corporation (USEC) to be sold as feed material to the commercial nuclear industry. Otherwise, blended LEU will be produced as a waste suitable for storage or disposal.

Review Of Rheology Models For Hanford Waste Blending  

SciTech Connect (OSTI)

The area of rheological property prediction was identified as a technology need in the Hanford Tank Waste - waste feed acceptance initiative area during a series of technical meetings among the national laboratories, Department of Energy-Office of River Protection, and Hanford site contractors. Meacham et al. delivered a technical report in June 2012, RPP-RPT-51652 ''One System Evaluation of Waste Transferred to the Waste Treatment Plant'' that included estimating of single shell tank waste Bingham plastic rheological model constants along with a discussion of the issues inherent in predicting the rheological properties of blended wastes. This report was selected as the basis for moving forward during the technical meetings. The report does not provide an equation for predicting rheological properties of blended waste slurries. The attached technical report gives an independent review of the provided Hanford rheological data, Hanford rheological models for single tank wastes, and Hanford rheology after blending provided in the Meacham report. The attached report also compares Hanford to SRS waste rheology and discusses some SRS rheological model equations for single tank wastes, as well as discussing SRS experience with the blending of waste sludges with aqueous material, other waste sludges, and frit slurries. Some observations of note: Savannah River Site (SRS) waste samples from slurried tanks typically have yield stress >1 Pa at 10 wt.% undissolved solids (UDS), while core samples largely have little or no yield stress at 10 wt.% UDS. This could be due to how the waste has been processed, stored, retrieved, and sampled or simply in the differences in the speciation of the wastes. The equations described in Meacham's report are not recommended for extrapolation to wt.% UDS beyond the available data for several reasons; weak technical basis, insufficient data, and large data scatter. When limited data are available, for example two to three points, the equations are not necessarily satisfactory (justified) for interpolations, due to the number of unknown variables equal the number of known data points, resulting in a coefficient of determination of one. SRS has had some success predicting the rheology of waste blends for similar waste types using rheological properties of the individual wastes and empirical blending viscosity equations. Both the Kendall-Monroe and Olney-Carlson equations were used. High accuracy was not obtained, but predictions were reasonable compared to measured flow curves. Blending SRS processed waste with frit slurry (much larger particles and the source of SRS glass formers) is a different sort of problem than that of two similar slurries of precipitated waste particles. A different approach to rheology prediction has had some success describing the incorporation of large frit particles into waste than the one used for blending two wastes. In this case, the Guth-Simha equation was used. If Hanford waste is found to have significant particles in the >100 ?m diameter range, then it might be necessary to handle those particles differently from broadly distributed waste particles that are primarily <30 ?m in diameter. The following are recommendations for the Hanford tank farms: Investigate the impact of large-scale mixing operations on yield stress for one or more Hanford tanks to see if Hanford waste rheological properties change to become more like SRS waste during both tank retrieval and tank qualification operations; Determine rheological properties of mobilized waste slurries by direct measurement rather than by prediction; Collect and characterize samples during the waste feed qualification process for each campaign; o From single source tanks that feed the qualification tanks; o Blends from the qualification tanks; Predictive rheological models must be used with caution, due to the lack of data to support such models and the utilization of the results that come from these models in making process decisions (e.g. the lack of actual operation experience). As experience is ga

Application of the distributed activation energy model to blends devolatilisation  

Science Journals Connector (OSTI)

In this study, an investigation was carried out into the thermal behaviour of coal, petcoke and their blend as a generic feedstock in combustion and IGCC plants for energy production. The samples were pyrolysed in a TG analyzer in nitrogen atmosphere (constant flow of 0.0335 m/s) at several heating rates with temperatures ranging from 300 to 1223 K. The distributed activation energy model was applied to study the effects of heating rates on the reactions of single solids. The results obtained were used in the calculation of curves mass loss vs. temperature at more realistic heating rates. The algorithm used to obtain the distribution of reactivities for single solids was successfully implemented to allow the prediction of blends performance.

Sulfur meter for blending coal at Plant Monroe: Final report  

SciTech Connect (OSTI)

An on-line sulfur analyzer, installed at the Detroit Edison, Monroe Power station, was placed into service and evaluated for coal blending optimization to minimize the cost of complying with changing stack gas sulfur dioxide regulations. The project involved debugging the system which consisted of an /open quotes/as-fired/close quotes/ sampler and nuclear source sulfur analyzer. The system was initially plagued with mechanical and electronic problems ranging from coal flow pluggages to calibration drifts in the analyzer. Considerable efforts were successfully made to make the system reliable and accurate. On-line testing showed a major improvement in control of sulfur dioxide emission rates and fuel blending optimization equivalent to as much as $6 million in fuel costs at the time of the evaluation. 7 refs., 14 figs., 12 tabs.

Course redesign for blended learning: modern optics for technical professionals  

Science Journals Connector (OSTI)

Philips Centre for Technical Training (CTT) is responsible for the on-going professional education of scientific staff in Philips Research Laboratories worldwide. This article addresses the ''why'' and ''how'' of an evolution toward more flexible learning at the CTT in which various models for blended learning supported by a web-based course-management system are being piloted and evaluated, and describes one of the courses in more detail. The ''why'' relates to CTT's challenge to give more participants at distant locations access to its courses. The ''how'' has to be appropriate to the very specific situation in which CTT functions the transfer of Philips' highly technical knowledge and experience to relatively small numbers of scientific staff within Philips. This knowledge and experience is being refreshed continuously so the contents of the learning also are in steady change. The blended learning models evolving at the CTT are grounded in these characteristics.

Effect of use of low oxygenate gasoline blends upon emissions from California vehicles. Final report  

SciTech Connect (OSTI)

The objective of this project was to investigate the emissions effects of low-oxygenate gasoline blends on exhaust and evaporative emissions from a test fleet of California certified light-duty autos. Thirteen vehicles were procured and tested using four gasoline-oxygenate blends over three test cycles. The four gasoline blends were: Methyl Tertiary Butyl Ether (MTBE), Ethyl Tertiary Butyl Ether (ETBE), and 'match' and 'splash' blends of ethanol (in the 'match' blend the fuel Reid Vapor Pressure (RVP) is held constant, while in the 'splash' blend the fuel RVP is allowed to increase). Hydrocarbon and carbon monoxide exhaust emissions were generally reduced for the oxygenated blends, the exception being the 'splash-blended' ethanol gasoline which showed mixed results. Older technology vehicles (e.g., non-catalyst and oxidation catalyst) showed the greatest emissions reductions regardless of gasoline blend, while later technology vehicles showed the smallest reductions. Evaporative emissions and toxics were generally reduced for ETBE, while results for the other blends were mixed.

Single Stage Contactor Testing Of The Next Generation Solvent Blend  

SciTech Connect (OSTI)

The Modular Caustic Side Solvent Extraction (CSSX) Unit (MCU) facility at the Savannah River Site (SRS) is actively pursuing the transition from the current BOBCalixC6 based solvent to the Next Generation Solvent (NGS)-MCU solvent to increase the cesium decontamination factor. To support this integration of NGS into the MCU facility the Savannah River National Laboratory (SRNL) performed testing of a blend of the NGS (MaxCalix based solvent) with the current solvent (BOBCalixC6 based solvent) for the removal of cesium (Cs) from the liquid salt waste stream. This testing utilized a blend of BOBCalixC6 based solvent and the NGS with the new extractant, MaxCalix, as well as a new suppressor, tris(3,7dimethyloctyl) guanidine. Single stage tests were conducted using the full size V-05 and V-10 liquid-to-liquid centrifugal contactors installed at SRNL. These tests were designed to determine the mass transfer and hydraulic characteristics with the NGS solvent blended with the projected heel of the BOBCalixC6 based solvent that will exist in MCU at time of transition. The test program evaluated the amount of organic carryover and the droplet size of the organic carryover phases using several analytical methods. The results indicate that hydraulically, the NGS solvent performed hydraulically similar to the current solvent which was expected. For the organic carryover 93% of the solvent is predicted to be recovered from the stripping operation and 96% from the extraction operation. As for the mass transfer, the NGS solvent significantly improved the cesium DF by at least an order of magnitude when extrapolating the One-stage results to actual Seven-stage extraction operation with a stage efficiency of 95%.

Abstract The need to produce energy from poor quality carbonaceous materials has increased, in order to reduce European dependency on imported fuels, diversify the use of new and alternative fuels and to guarantee secure energy production routes. The valorisation of a poor quality solid residual fuel (SRF), with high content of ash and volatile matter, through its conversion into fuel gas was studied. The rise of gasification temperature and equivalent ratio (ER) led to higher gas yields and to lower undesirable gaseous components, though higher ER values led to a gas with lower energetic content. To reduce the negative effect of SRF unfavourable characteristics and to diversify the feedstocks used, SRF blended with three different types of biomass wastes: forestry pine, almond shells and olive bagasse was co-gasified. The use of biomass wastes tested was valuable for SRF gasification, as there was an increase in the overall reactivity and in H2 production and a reduction of about 55% in tar released, without great changes in gas yield and in its HHV. The use of natural minerals mixed with silica sand was also studied with the aim of improving SRF gasification performance and fuel gas quality. The best results were obtained in presence of dolomite, as the lowest tar and H2S contents were obtained, while an increase in gas yield was observed. Co-gasification of this poor quality SRF blended with biomass wastes in presence of dolomite increased gas yield by 25% while tar contents decreased by 55%.

Exhaust emissions and mutagenic effects of diesel fuel, biodiesel and biodiesel blends  

Science Journals Connector (OSTI)

Abstract The replacement of petroleum-derived fuels by renewable biogenic fuels has become of worldwide interest with the environmental effects being scientifically investigated. Biodiesel has been proven to be a suitable alternative to petrodiesel and blending up to 20% biodiesel with petrodiesel is policy promoted in the USA and the EU. To investigate the influence of blends on the exhaust emissions and possible health effects, we performed a series of studies with several engines (Euro 0, III and IV) using blends of rapeseed-derived biodiesel and petrodiesel. Regulated and non-regulated exhaust compounds were measured and their mutagenic effects were determined using the Bacterial Reverse Mutation Assay (Ames-Test) according to OECD Guideline 471. Exhaust emissions of blends were approximately linearly dependent on the blend composition, particularly when considering regulated emissions. However, a negative effect of blends was observed with respect to mutagenicity of the exhaust emissions. In detail, an increase of the mutagenic potential was found for blends with the maximum observed for B20. From this point of view, B20 must be considered as a critical blend when petrodiesel and biodiesel are used as binary mixtures.

Synergistic Effect of coal blends on thermoplasticity evaluated using a temperature-variable dynamic viscoelastic measurement  

SciTech Connect (OSTI)

To maximize the conversion of low-quality coal into good coke, we investigated the thermoplasticity of various binary blends of caking coals with slightly or noncaking coals using a dynamic viscoelastic technique with a temperature-variable rheometer. Coal blend samples were prepared by mixing two coals (1:1 by weight), which were heated from room temperature to 600 C at a rate of 3-80{sup o}C/min. At the slow rate of 3{sup o}C/min, the blends had a tan {delta} that was generally lower than the calculated value, showing that a negative interaction caused a loss of thermoplasticity. In contrast, at the rapid heating rate of 80{sup o}C/min, the tan {delta} of some blends was higher than the calculated value, indicating a positive interaction that enhanced the thermoplasticity. With rapid heating, the thermoplasticity of each coal itself increased, and their thermoplastic temperature ranges widened with rapid heating. Therefore, rapid heating was effective at converting these coal blends into good cokes. Moreover, even with slow heating, when a combination of coals (Gregory:Enshu, 1:1) showing some thermoplasticity in nearly the same temperature range was blended, a desirable synergistic effect of the blend was obtained. This suggests that blending coal with an overlapping thermoplastic temperature range is important for the synergistic effect, regardless of the heating rate. 15 refs., 9 figs., 2 tabs.

Effects of HyperCoal addition on coke strength and thermoplasticity of coal blends  

SciTech Connect (OSTI)

Ashless coal, also known as HyperCoal (HPC), was produced by thermal extraction of three coals of different ranks (Gregory caking coal, Warkworth steam coal, and Pasir subbituminous coal) with 1-methylnaphthalene (1-MN) at 360, 380, and 400{sup o}C. The effects of blending these HPCs into standard coal blends were investigated. Blending HPCs as 5-10% of a standard blend (Kouryusho:Goonyella:K9) enhanced the thermoplasticity over a wide temperature range. For blends made with the Pasir-HPC, produced from a noncaking coal, increasing the extraction temperature from 360 to 400{sup o}C increased the thermoplasticity significantly. Blends containing Warkworth-HPC, produced from a slightly caking coal, had a higher tensile strength than the standard blend in semicoke strength tests. The addition of 10% Pasir-HPC, extracted at 400{sup o}C, increased the tensile strength of the semicokes to the same degree as those made with Gregory-HPC. Furthermore, all HPC blends had a higher tensile strength and smaller weight loss during carbonization. These results suggest that the HPC became integrated into the coke matrix, interacting strongly with the other raw coals. 14 refs., 11 figs., 1 tab.

JV Task 112-Optimal Ethanol Blend-Level Investigation  

SciTech Connect (OSTI)

Highway Fuel Economy Test (HWFET) and Federal Test Procedure 75 (FTP-75) tests were conducted on four 2007 model vehicles; a Chevrolet Impala flex-fuel and three non-flex-fuel vehicles: a Ford Fusion, a Toyota Camry, and a Chevrolet Impala. This investigation utilized a range of undenatured ethanol/Tier II gasoline blend levels from 0% to 85%. HWFET testing on ethanol blend levels of E20 in the flex fuel Chevrolet Impala and E30 in the non-flex-fuel Ford Fusion and Toyota Camry resulted in miles-per-gallon (mpg) fuel economy greater than Tier 2 gasoline, while E40 in the non-flex-fuel Chevrolet Impala resulted in an optimum mpg based on per-gallon fuel Btu content. Exhaust emission values for non-methane organic gases (NMOG), carbon monoxide (CO), and nitrogen oxides (NO{sub x}) obtained from both the FTP-75 and the HWFET driving cycles were at or below EPA Tier II, Light-Duty Vehicles, Bin 5 levels for all vehicles tested with one exception. The flex-fuel Chevrolet Impala exceeded the NMOG standard for the FTP-75 on E-20 and Tier II gasoline.

Relationship between coking pressure generated by coal blends and the composition of their primary tars  

Science Journals Connector (OSTI)

Four coals that develop different pressures during the coking process were selected together with 10 blends (7 binary and 3 ternary) prepared with the same coals. Their semicoke contraction/expansion was measured by means of two tests (the Koppers-INCAR and the sole heated oven) and the variation in coking pressure during coking was determined in a movable wall oven. The coals and blends were then pyrolysed and the tars were analysed by gas chromatography (GC-FID–MS). The additivity law was applied to the properties used to evaluate the dangerousness of the blends and to the composition of the tar produced from the blends. Afterwards, the composition of the tar was studied in relation to contraction/expansion and the coking pressure generated by the coals and blends.

Effect of compatibilizer on impact and morphological analysis of recycled HDPE/PET blends  

SciTech Connect (OSTI)

Blends based on recycled high density polyethylene (rHDPE) and recycled polyethylene terephthalate (rPET) were prepared using a corotating twin screw extruder. PET and HDPE are incompatible polymers and their blends showed poor properties. Compatibilization is a step to obtain blends with good mechanical properties and in this work, ethylene glycidyl methacrylate copolymer (E-GMA) was used as a compatibilizing agent. The effect of blends based on rHDPE and rPET with and without a compatibilizer, E-GMA were examined. From the studies clearly showed that the addition of 5% E-GMA increased the impact strength. SEM analysis of rHDPE/rPET blends confirmed the morphological interaction and improved interfacial bonding between two phases.

Chapter 30 - Biofuel Economics and Policy: The Renewable Fuel Standard, the Blend Wall, and Future Uncertainties  

Science Journals Connector (OSTI)

Abstract Biofuels are currently in a state of flux. The main operative policy for biofuels in the United States is the Renewable Fuel Standard (RFS). It specifies a minimum quantity of four different types of biofuels that must be blended each year in the United States through 2022. However, the United States also faces what is called the blend wall, which is a physical limit on blending given that the United States blends at a 10% rate. The blend wall upper limit is now below the RFS lower limit for corn ethanol, and that is causing problems with the administration of the RFS. This chapter explains how the RFS functions and then examines alternatives to the current administration of the RFS. The RFS is critical for cellulosic biofuels and biodiesel, and its elimination would likely end use of those fuels. Corn ethanol, however, is now much less expensive than gasoline and would continue.

Flow boundary conditions for chain-end adsorbing polymer blends  

E-Print Network [OSTI]

Using the phenol-terminated polycarbonate blend as an example, we demonstrate that the hydrodynamic boundary conditions for a flow of an adsorbing polymer melt are extremely sensitive to the structure of the epitaxial layer. Under shear, the adsorbed parts (chain ends) of the polymer melt move along the equipotential lines of the surface potential whereas the adsorbed additives serve as the surface defects. In response to the increase of the number of the adsorbed additives the surface layer becomes thinner and solidifies. This results in a gradual transition from the slip to the no-slip boundary condition for the melt flow, with a non-monotonic dependence of the slip length on the surface concentration of the adsorbed ends.

Fuel-blending stocks from the hydrotreatment of a distillate formed by direct coal liquefaction  

SciTech Connect (OSTI)

The direct liquefaction of coal in the iron-catalyzed Suplex process was evaluated as a technology complementary to Fischer-Tropsch synthesis. A distinguishing feature of the Suplex process, from other direct liquefaction processes, is the use of a combination of light- and heavy-oil fractions as the slurrying solvent. This results in a product slate with a small residue fraction, a distillate/naphtha mass ratio of 6, and a 65.8 mass % yield of liquid fuel product on a dry, ash-free coal basis. The densities of the resulting naphtha (C{sub 5}-200{sup o}C) and distillate (200-400{sup o}C) fractions from the hydroprocessing of the straight-run Suplex distillate fraction were high (0.86 and 1.04 kg/L, respectively). The aromaticity of the distillate fraction was found to be typical of coal liquefaction liquids, at 60-65%, with a Ramsbottom carbon residue content of 0.38 mass %. Hydrotreatment of the distillate fraction under severe conditions (200{sup o}C, 20.3 MPa, and 0.41 g{sub feed} h{sup -1} g{sub catalyst}{sup -1}) with a NiMo/Al{sub 2}O{sub 3} catalyst gave a product with a phenol content of {lt}1 ppm, a nitrogen content {lt}200 ppm, and a sulfur content {lt}25 ppm. The temperature was found to be the main factor affecting diesel fraction selectivity when operating at conditions of WHSV = 0.41 g{sub feed} h{sup -1} g{sub catalyst}{sup -1} and PH{sub 2} = 20.3 MPa, with excessively high temperatures (T {gt} 420{sup o}C) leading to a decrease in diesel selectivity. The fuels produced by the hydroprocessing of the straight-run Suplex distillate fraction have properties that make them desirable as blending components, with the diesel fraction having a cetane number of 48 and a density of 0.90 kg/L. The gasoline fraction was found to have a research octane number (RON) of 66 and (N + 2A) value of 100, making it ideal as a feedstock for catalytic reforming and further blending with Fischer-Tropsch liquids. 44 refs., 9 figs., 12 tabs.

The radiation crosslinking of poly(vinyl chloride) with trimethylolpropanetrimethacrylate. III. Effect of diundecyl phthalate: chemical kinetics of a three-component system  

SciTech Connect (OSTI)

The radiation chemistry of poly(vinyl chloride) (PVC) blended with trimethylolpropanetrimethacrylate (TMPTMA) and diundecyl phthalate (DUP) has been examined. This three-component mixture contains a base resin (PVC), a crosslinking sensitizer (TMPTMA), and a physical modifier (DUP). These are the basic components in any radiation-curable coating. The kinetics and mechanism of the crosslinking reactions were studied with reference to the dependence on radiation dose and blend composition. The polyfunctional TMPTMA underwent polymerization incorporating the PVC into a 3-dimensional network. DUP remained chemically inert during the irradiation, not being bound to the network. However, DUP by plasticizing the macromolecules and diluting the monomer, changed the kinetics extensively. DUP enhanced TMPTMA homopolymerization, TMPTMA grafting, and PVC crosslinking reaction rates. The effect of the competition between polymerization, grafting, and degradation reactions was examined in terms of enhanced mobility of the reacting species. The influence of these kinetics considerations in selecting a blend composition for a coating application was discussed.

Profit and policy implications of producing biodiesel–ethanol–diesel fuel blends to specification  

Science Journals Connector (OSTI)

A nonlinear optimization model is developed in this work to analyze biodiesel–ethanol–diesel (BED) ternary blending processes. The model establishes optimal blends to improve the system profitability given production costs, market demand, and fuel prices while meeting multiple property criteria such as kinematic viscosity, density, lower heating value, cloud point, cetane number, fuel stability and sulfur content. Pertinent fuel mixing rules for predicting the fuel properties of BED blends were extrapolated from previous works and applied as constraints to the present model. Several dynamic and/or uncertainty factors were explored in further depth to quantify their impacts on the fuel composition of BED blends including petro-diesel supply reduction, diesel production cost, diesel blends market retail price, and policy changes on bio-fuel subsidies. By examining key optimization sensitivity analysis such as shadow prices and opportunity costs, the crucial limits or constraints on fuel specifications can be identified and used to proactively identify and promote the development of potential additives. The model also suggests the government policy of simultaneously implementing bio-fuel tax credits and mandates may not have a higher contribution to promoting bio-fuel production than the case only with tax credits for the firms with the goal of profit maximization. The firms enable 5–8% increase of the optimal profit from BED blends by utilizing ethanol derived from food waste feedstocks instead of edible biomass.

We study how this multi-component multi-executable application can run effectively on distributed memory archi- tectures. We identify five effective execution modes and de- velop the MPH library to support

LMFBR fuel component costs  

SciTech Connect (OSTI)

A significant portion of the cost of fabricating LMFBR fuels is in the non-fuel components such as fuel pin cladding, fuel assembly ducts and end fittings. The contribution of these to fuel fabrication costs, based on FFTF experience and extrapolated to large LMFBR fuel loadings, is discussed. The extrapolation considers the expected effects of LMFBR development programs in progress on non-fuel component costs.

Hybrid Dynamic Density Functional Theory for Polymer Melts and Blends  

E-Print Network [OSTI]

We propose a high-speed and accurate hybrid dynamic density functional theory for the computer simulations of the phase separation processes of polymer melts and blends. The proposed theory is a combination of the dynamic self-consistent field (SCF) theory and a time-dependent Ginzburg-Landau type theory with the random phase approximation (GRPA). The SCF theory is known to be accurate in evaluating the free energy of the polymer systems in both weak and strong segregation regions although it has a disadvantage of the requirement of a considerable amount of computational cost. On the other hand, the GRPA theory has an advantage of much smaller amount of required computational cost than the SCF theory while its applicability is limited to the weak segregation region. To make the accuracy of the SCF theory and the high-performance of the GRPA theory compatible, we adjust the chemical potential of the GRPA theory by using the SCF theory every constant time steps in the dynamic simulations. The performance of the GRPA and the hybrid theories is tested by using several systems composed of an A/B homopolymer, an AB diblock copolymer, or an ABC triblock copolymer. Using the hybrid theory, we succeeded in reproducing the metastable complex phase-separated domain structures of an ABC triblock copolymer observed by experiments.

Tailoring key fuel properties of diesel–biodiesel–ethanol blends for diesel engine  

Science Journals Connector (OSTI)

Alternative fuel research for the profusely growing number of diesel run automotive has intensified due to environmental reasons and turmoil in petroleum market. Government initiatives all around the world, their energy policies and steps to emphasis the use of biodiesel; proved biodiesel as a number one renewable substitute for No. 2 diesel fuels. Among all biodiesel feedstock, palm oil is a potential source with higher yield rate without much fertilizer use especially in tropical region. However, the application of transesterified palm biodiesel is objected by many auto-manufacturers due to adverse effects on engine in long term operation. The aim of this study was to modify the key fuel properties of palm biodiesel which causes engine fouling in long term operation. A significant amount of work is devoted to mix biodiesel and diesel at arbitrary percentages and test engine performance. Numerous fuel additives are developed for biodiesels automotive use. In this study, chemical properties of biodiesel are tailored by ethanol and an optimum formulation is derived mathematically. Ethanol is used at a controlled proportion (6%) with palm oil methyl ester (POME) as additive to reduce the higher viscosity of POME. This optimum palm biodiesel–ethanol blend was mixed at varying proportions (i.e. 0–30%) with No. 2 diesel to produce ternary blends of diesel–palm biodiesel–ethanol. Cold flow properties (such as, could point, pour point) of these ternary blends has improved and minute percentage of ethanol adding did not adversely affect the oxidation stability and corrosiveness of the fuel blend. Ethanol has significantly reduces the flash point, but the flammability of ternary blends is classified as Class II; similar to that of diesel. Cetane number is reduced in ternary blends by ethanol. So, palm biodiesel with minute percentage of anhydrous ethanol as additive in the ternary blend significantly improved key fuel properties significantly.

Vaporization modeling of petroleum-biofuel drops using a hybrid multi-component approach  

SciTech Connect (OSTI)

Numerical modeling of the vaporization characteristics of multi-component fuel mixtures is performed in this study. The fuel mixtures studied include those of binary components, biodiesel, diesel-biodiesel, and gasoline-ethanol. The use of biofuels has become increasingly important for reasons of environmental sustainability. Biofuels are often blended with petroleum fuels, and the detailed understanding of the vaporization process is essential to designing a clean and efficient combustion system. In this study, a hybrid vaporization model is developed that uses continuous thermodynamics to describe petroleum fuels and discrete components to represent biofuels. The model is validated using the experimental data of n-heptane, n-heptane-n-decane mixture, and biodiesel. Since biodiesel properties are not universal due to the variation in feedstock, methods for predicting biodiesel properties based on the five dominant fatty acid components are introduced. Good levels of agreement in the predicted and measured drop size histories are obtained. Furthermore, in modeling the diesel-biodiesel drop, results show that the drop lifetime increases with the biodiesel concentration in the blend. During vaporization, only the lighter components of diesel fuel vaporize at the beginning. Biodiesel components do not vaporize until some time during the vaporization process. On the other hand, results of gasoline-ethanol drops indicate that both fuels start to vaporize once the process begins. At the beginning, the lighter components of gasoline have a slightly higher vaporization rate than ethanol. After a certain time, ethanol vaporizes faster than the remaining gasoline components. At the end, the drop reduces to a regular gasoline drop with heavier components. Overall, the drop lifetime increases as the concentration of ethanol increases in the drop due to the higher latent heat. (author)

SAVANNAH RIVER SITE INCIPIENT SLUDGE MIXING IN RADIOACTIVE LIQUID WASTE STORAGE TANKS DURING SALT SOLUTION BLENDING  

SciTech Connect (OSTI)

This paper is the second in a series of four publications to document ongoing pilot scale testing and computational fluid dynamics (CFD) modeling of mixing processes in 85 foot diameter, 1.3 million gallon, radioactive liquid waste, storage tanks at Savannah River Site (SRS). Homogeneous blending of salt solutions is required in waste tanks. Settled solids (i.e., sludge) are required to remain undisturbed on the bottom of waste tanks during blending. Suspension of sludge during blending may potentially release radiolytically generated hydrogen trapped in the sludge, which is a safety concern. The first paper (Leishear, et. al. [1]) presented pilot scale blending experiments of miscible fluids to provide initial design requirements for a full scale blending pump. Scaling techniques for an 8 foot diameter pilot scale tank were also justified in that work. This second paper describes the overall reasons to perform tests, and documents pilot scale experiments performed to investigate disturbance of sludge, using non-radioactive sludge simulants. A third paper will document pilot scale CFD modeling for comparison to experimental pilot scale test results for both blending tests and sludge disturbance tests. That paper will also describe full scale CFD results. The final paper will document additional blending test results for stratified layers in salt solutions, scale up techniques, final full scale pump design recommendations, and operational recommendations. Specifically, this paper documents a series of pilot scale tests, where sludge simulant disturbance due to a blending pump or transfer pump are investigated. A principle design requirement for a blending pump is UoD, where Uo is the pump discharge nozzle velocity, and D is the nozzle diameter. Pilot scale test results showed that sludge was undisturbed below UoD = 0.47 ft{sup 2}/s, and that below UoD = 0.58 ft{sup 2}/s minimal sludge disturbance was observed. If sludge is minimally disturbed, hydrogen will not be released. Installation requirements were also determined for a transfer pump which will remove tank contents, and which is also required to not disturb sludge. Testing techniques and test results for both types of pumps are presented.

-01-0474 -01-0474 The effects of blending hydrogen with methane on engine operation, efficiency, and emissions Thomas Wallner and Henry K. Ng Argonne National Laboratory Robert W. Peters University of Alabama at Birmingham Copyright © 2007 SAE International ABSTRACT Hydrogen is considered one of the most promising future energy carriers and transportation fuels. Because of the lack of a hydrogen infrastructure and refueling stations, widespread introduction of vehicles powered by pure hydrogen is not likely in the near future. Blending hydrogen with methane could be one solution. Such blends take advantage of the unique combustion properties of hydrogen and, at the same time, reduce the demand for pure hydrogen.

Drive cycle analysis of butanol/diesel blends in a light-duty vehicle.  

SciTech Connect (OSTI)

The potential exists to displace a portion of the petroleum diesel demand with butanol and positively impact engine-out particulate matter. As a preliminary investigation, 20% and 40% by volume blends of butanol with ultra low sulfur diesel fuel were operated in a 1999 Mercedes Benz C220 turbo diesel vehicle (Euro III compliant). Cold and hot start urban as well as highway drive cycle tests were performed for the two blends of butanol and compared to diesel fuel. In addition, 35 MPH and 55 MPH steady-state tests were conducted under varying road loads for the two fuel blends. Exhaust gas emissions, fuel consumption, and intake and exhaust temperatures were acquired for each test condition. Filter smoke numbers were also acquired during the steady-state tests.

Performance of a direct diesel engine using aviation fuels blended with biodiesel  

Science Journals Connector (OSTI)

In this study, jet fuel (JF) and railroad fuel (D2) with SME blends (5%, 20%, 50%) were used in a four-cylinder, naturally aspirated, direct (DI) diesel engine. The engine was operated under full load and tested at various speeds to determine the engine's performance and exhaust emission characteristics. The experimental results show that as the SME ratio of the fuels increases, the break specific fuel consumption (BSFC) and exhaust temperature increase; the SME and its blends show a slight drop in engine performance. In this experiment, carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOx) and smoke opacity values were measured for each fuel. The results of the emission tests revealed that the oxygen content of SME provided a significant reduction in CO and smoke opacity emissions. However, when the test engine was fuelled by SME and its blends, NOx emissions increased.

Sample Results From The Extraction, Scrub, And Strip Test For The Blended NGS Solvent  

SciTech Connect (OSTI)

This report summarizes the results of the extraction, scrub, and strip testing for the September 2013 sampling of the Next Generation Solvent (NGS) Blended solvent from the Modular Caustic Side-Solvent Extraction Unit (MCU) Solvent Hold Tank. MCU is in the process of transitioning from the BOBCalixC6 solvent to the NGS Blend solvent. As part of that transition, MCU has intentionally created a blended solvent to be processed using the Salt Batch program. This sample represents the first sample received from that blended solvent. There were two ESS tests performed where NGS blended solvent performance was assessed using either the Tank 21 material utilized in the Salt Batch 7 analyses or a simulant waste material used in the V-5/V-10 contactor testing. This report tabulates the temperature corrected cesium distribution, or DCs values, step recovery percentage, and actual temperatures recorded during the experiment. This report also identifies the sample receipt date, preparation method, and analysis performed in the accumulation of the listed values. The calculated extraction DCs values using the Tank 21H material and simulant are 59.4 and 53.8, respectively. The DCs values for two scrub and three strip processes for the Tank 21 material are 4.58, 2.91, 0.00184, 0.0252, and 0.00575, respectively. The D-values for two scrub and three strip processes for the simulant are 3.47, 2.18, 0.00468, 0.00057, and 0.00572, respectively. These values are similar to previous measurements of Salt Batch 7 feed with lab-prepared blended solvent. These numbers are considered compatible to allow simulant testing to be completed in place of actual waste due to the limited availability of feed material.

Effects of the blends containing low ratios of alternative fuels on the performance and emission characteristics of a diesel engine  

Science Journals Connector (OSTI)

The aim of this study is to experimentally investigate the effects of blends containing various alternative fuels and diesel fuel on the performance and emissions of a diesel engine. The considered parameters are brake power, specific fuel consumption and thermal efficiency as well as carbon monoxide, hydrocarbon and nitrogen oxide emissions. Blends of biodiesel, ethanol, methanol and vegetable oil with diesel fuel, each containing 15% alternative fuel in volume, were prepared. Then, these blends were tested in a naturally aspirated, direct injection diesel engine. The test results obtained with these blends were compared with those obtained with diesel fuel. It was found that the tested blends yielded usually different performance and emission characteristics compared to diesel fuel. The biodiesel blend resulted in performance parameters very close to those obtained in the use of diesel fuel. Ethanol and methanol blends yielded lower brake power, while they resulted in higher specific fuel consumption and lower carbon monoxide emissions. On the other hand, the vegetable oil blend yielded lower carbon monoxide emissions, while it caused only slight changes in the performance parameters.

Surface-induced First Order Transition in Athermal Polymer/Nanoparticle Blends  

E-Print Network [OSTI]

We investigate the phase behavior of athermal polymer/nanoparticle blends near a hard substrate. We apply the density functional theory of Tripathi and Chapman to these blends. We find a first order phase transition where the nanoparticles expel the polymer from the surface to form a monolayer. The transition density depends on the polymer length and the system bulk density. The effect is due to the packing entropy of the species and configurational entropy of the polymer. The simplicity of the system allows us to understand the so-called ``entropic-push'' observed in experiments.

Prediction of metallurgical coke strength from the petrographic composition of coal blends  

SciTech Connect (OSTI)

Turkey, especially Zonguldak on the West Coast of Black Sea region, has large reserves of bituminous coal that can be used either directly or in blends with other coals for metallurgical coke production. It is possible to predict the coking properties of these coals by petrographic analysis. In this study, semi- and non-coking coals were blended with coking bituminous coals in varying proportions and an estimation was made as to their stability factors through petrographic techniques. It was established that semi- and non-coking bituminous coals could be used in the production of metallurgical coke.

Use of ethers as high-octane components of gasolines  

SciTech Connect (OSTI)

This article reports on a study of the possible utilization of methyl tert-amyl ether (MTAE) as an automotive gasoline component, both by itself and in combination with methyl tert-butyl ether (MTBE). The naphtha used in these studies consisted of 80% reformer naphtha produced under severe conditions and 20% straight-run IBP-62/sup 0/C cut. The physicochemical properties of the MTAE, the MTBE, and the naphtha base stock are given. It is determined that MTAE, which has a slightly poorer knock resistance than MTBE, is fully equal to MTBE in all other respects and can be used as an automotive gasoline component; that a gasoline blend prepared from 89% naphtha base stock, 5.5% MTAE, and 5.5% MTBE meets all of the requirements of the standard GOST 2084-77 for Grade AI-93 gasoline; and that the use of MTAE offers a means for expanding the resources of high-octane components, lowering the toxicity of the gasolines and the exhaust gas (in comparison with organometallic antiknock agents), and bringing non-petroleum raw materials into the fuel production picture.

Comparison of blends of conventional diesel fuel and CRBO containing high levels of FFA in a DI diesel engine  

Science Journals Connector (OSTI)

This work attempts to analyse the ability of high free fatty acid (FFA) crude rice bran oil (CRBO) in replacing diesel partially in a compression ignition (CI) engine. It was observed that the delay period and the maximum rate of pressure rise for CRBO blends are lower than diesel and is almost inversely proportional to FFA content. Maximum heat release rate for CRBO blends are lower and occur earlier than that of diesel. CRBO blends require longer duration to release 90% of heat than diesel and it decreases with increase in FFA content of CRBO. When operating with CRBO blends, all emission parameters were decreased significantly with a marginal increase in CO emission than that of diesel without affecting the brake thermal efficiency of the engine. It is concluded that higher FFA of CRBO blends does not inhibit its ability to be utilised as a fuel in CI engines.

Thermochemical and trace element behavior of coal gangue, agricultural biomass and their blends during co-combustion  

Science Journals Connector (OSTI)

Abstract The thermal decomposition behavior of coal gangue, peanut shell, wheat straw and their blends during combustion were determined via thermogravimetric analysis. The coal gangue/agricultural biomass blends were prepared in four weight ratios and oxidized under dynamic conditions from room temperature to 1000 °C by various heating rates. Kinetic models were carried out to evaluate the thermal reactivity. The overall mass balance was performed to assess the partition behavior of coal gangue, peanut shell and their blends during combustion in a fixed bed reactor. The decomposition processes of agricultural biomass included evaporation, release of volatile matter and combustion as well as char oxidation. The thermal reactivity of coal gangue could be improved through the addition of agricultural biomass in suitable proportion and subsequent appropriate heating rate during combustion. In combination with the heating value and base/acid ratio limitations, a blending ratio of 30% agricultural biomass is conservatively selected as optimum blending.

Hypocholesterolemic effect of some plants and their blend as studied on albino rats  

Science Journals Connector (OSTI)

This work was carried out to evaluate the hypocholesterolemia effect of esparto grass leaves, fenugreek seeds powder, myrrh resin and their blend (prepared using equal amounts of each) on albino rats. Half, fenugreek and the blend were added to basal diet at 5% and 10%, while myrrh added at 2.5% and 5% hypercholesterolemia raised serum TC, TG, LDL and VLDL while HDL declined. Feeding on mentioned plants reversed the mentioned change provided that efficacy was different where the blend mostly came first, being of highest effect (indicating a synergistic action) and fenugreek of lowest effect. Fenugreek seeds powder showed 34.50-43.75% decrease of AI compared to control (+). Serum glucose showed 31.25% increase due to hypercholesterolemia, and decreased from 141.13 mg dl?1 (control+) to 97.1-127.0 mg dl?1 by experimental diets; in this concern the blend diet was of highest effect. More studies are needed to confirm the effect of myrrh as overweight and obesity controller agent.

Interfacial morphology and friction properties of thin PEO and PEO/PAA blend films  

Science Journals Connector (OSTI)

The scanning force microscope (SFM) was used to investigate morphology of poly(ethylene oxide) (PEO) and poly(acrylic acid) (PAA) blend. The effect of solvent and dewetting in surface structure of PEO film was reported. The results manifested that the crystallization of PEO could be suppressed completely in ultrathin region via using chloroform as a solvent, and the branched-like crystallization was recovered after dewetting. Also, the effect of thickness, the ratio of PEO/PAA and dewetting in surface morphology of PEO–PAA blend films were investigated. These results showed that the crystallization was highly dependent on the ratio of PEO/PAA and the thickness of blend film. Furthermore, we assembled the PEO/PAA layer-by-layer film by spin-casting method for the first time, which exhibited highly efficiency. As a complementary tool, we also used lateral force microscopy (LFM) to explore surface information of these films. The result was indicative of interfacial constraints in ultrathin region, and also was supported by the results showing the spin-casting PEO/PAA blends rather than heterogeneous mixture.

Component failure data handbook  

SciTech Connect (OSTI)

This report presents generic component failure rates that are used in reliability and risk studies of commercial nuclear power plants. The rates are computed using plant-specific data from published probabilistic risk assessments supplemented by selected other sources. Each data source is described. For rates with four or more separate estimates among the sources, plots show the data that are combined. The method for combining data from different sources is presented. The resulting aggregated rates are listed with upper bounds that reflect the variability observed in each rate across the nuclear power plant industry. Thus, the rates are generic. Both per hour and per demand rates are included. They may be used for screening in risk assessments or for forming distributions to be updated with plant-specific data.

Precision Cleaning Titanium Components  

SciTech Connect (OSTI)

Clean bond surfaces are critical to the operation of diffusion bonded titanium engine components. These components can be contaminated with machining coolant, shop dirt, and fingerprints during normal processing and handling. These contaminants must be removed to achieve acceptable bond quality. As environmental concerns become more important in manufacturing, elimination of the use of hazardous materials is desired. For this reason, another process (not using nitric-hydrofluoric acid solution) to clean titanium parts before bonding was sought. Initial cleaning trials were conducted at Honeywell to screen potential cleaning techniques and chemistries. During the initial cleaning process screening phase, Pratt and Whitney provided Honeywell with machined 3 inch x 3 inch x 1 inch titanium test blocks. These test blocks were machined with a water-based machining coolant and exposed to a normal shop environment and handling. (Honeywell sectioned one of these blocks into smaller samples to be used for additional cleanliness verification analyses.) The sample test blocks were ultrasonically cleaned in alkaline solutions and AUGER analysis was used by Honeywell FM and T to validate their cleanliness. This information enabled selection of final cleaning techniques and solutions to be used for the bonding trials. To validate Honeywell's AUGER data and to verify the cleaning processes in actual situations, additional sample blocks were cleaned (using the chosen processes) and then bonded. The bond quality of the test blocks was analyzed according to Pratt and Whitney's requirements. The Charpy impact testing was performed according to ASTM procedure {number_sign}E-23. Bond quality was determined by examining metallographic samples of the bonded test blocks for porosity along the bondline.

NUCLEAR ISOTOPIC DILUTION OF HIGHLY ENRICHED URANIUM BY DRY BLENDING VIA THE RM-2 MILL TECHNOLOGY  

SciTech Connect (OSTI)

DOE has initiated numerous activities to focus on identifying material management strategies to disposition various excess fissile materials. In particular the INEEL has stored 1,700 Kg of offspec HEU at INTEC in CPP-651 vault facility. Currently, the proposed strategies for dispositioning are (a) aqueous dissolution and down blending to LEU via facilities at SRS followed by shipment of the liquid LEU to NFS for fabrication into LWR fuel for the TVA reactors and (b) dilution of the HEU to 0.9% for discard as a waste stream that would no longer have a criticality or proliferation risk without being processed through some type of enrichment system. Dispositioning this inventory as a waste stream via aqueous processing at SRS has been determined to be too costly. Thus, dry blending is the only proposed disposal process for the uranium oxide materials in the CPP-651 vault. Isotopic dilution of HEU to typically less than 20% by dry blending is the key to solving the dispositioning issue (i.e., proliferation) posed by HEU stored at INEEL. RM-2 mill is a technology developed and successfully tested for producing ultra-fine particles by dry grinding. Grinding action in RM-2 mill produces a two million-fold increase in the number of particles being blended in a centrifugal field. In a previous study, the concept of achieving complete and adequate blending and mixing (i.e., no methods were identified to easily separate and concentrate one titanium compound from the other) in remarkably short processing times was successfully tested with surrogate materials (titanium dioxide and titanium mono-oxide) with different particle sizes, hardness and densities. In the current project, the RM-2 milling technology was thoroughly tested with mixtures of natural uranium oxide (NU) and depleted uranium oxide (DU) stock to prove its performance. The effects of mill operating and design variables on the blending of NU/DU oxides were evaluated. First, NU and DU both made of the same oxide, UO{sub 3}, was used in the testing. Next, NU made up of UO{sub 3} and DU made up of UO{sub 2} was used in the test work. In every test, the blend achieved was characterized by spatial sampling of the ground product and analyzing for {sup 235}U concentration. The test work proved that these uranium oxide materials can be blended successfully. The spatial concentration was found to be uniform. Next, sintered thorium oxide pellets were used as surrogate for light water breeder reactor pellets (LWBR). To simulate LWBR pellet dispositioning, the thorium oxide pellets were first ground to a powder form and then the powder was blended with NU. In these tests also the concentration of {sup 235}U and {sup 232}Th in blended products fell within established limits proving the success of RM-2 milling technology. RM-2 milling technology is applicable to any dry radioactive waste, especially brittle solids that can be ground up and mixed with the non-radioactive stock.

Compatibility Study for Plastic, Elastomeric, and Metallic Fueling Infrastructure Materials Exposed to Aggressive Formulations of Ethanol-blended Gasoline  

SciTech Connect (OSTI)

In 2008 Oak Ridge National Laboratory began a series of experiments to evaluate the compatibility of fueling infrastructure materials with intermediate levels of ethanol-blended gasoline. Initially, the focus was elastomers, metals, and sealants, and the test fuels were Fuel C, CE10a, CE17a and CE25a. The results of these studies were published in 2010. Follow-on studies were performed with an emphasis on plastic (thermoplastic and thermoset) materials used in underground storage and dispenser systems. These materials were exposed to test fuels of Fuel C and CE25a. Upon completion of this effort, it was felt that additional compatibility data with higher ethanol blends was needed and another round of experimentation was performed on elastomers, metals, and plastics with CE50a and CE85a test fuels. Compatibility of polymers typically relates to the solubility of the solid polymer with a solvent. It can also mean susceptibility to chemical attack, but the polymers and test fuels evaluated in this study are not considered to be chemically reactive with each other. Solubility in polymers is typically assessed by measuring the volume swell of the polymer exposed to the solvent of interest. Elastomers are a class of polymers that are predominantly used as seals, and most o-ring and seal manufacturers provide compatibility tables of their products with various solvents including ethanol, toluene, and isooctane, which are components of aggressive oxygenated gasoline as described by the Society of Automotive Engineers (SAE) J1681. These tables include a ranking based on the level of volume swell in the elastomer associated with exposure to a particular solvent. Swell is usually accompanied by a decrease in hardness (softening) that also affects performance. For seal applications, shrinkage of the elastomer upon drying is also a critical parameter since a contraction of volume can conceivably enable leakage to occur. Shrinkage is also indicative of the removal of one or more components of the elastomers (by the solvent). This extraction of additives can negatively change the properties of the elastomer, leading to reduced performance and durability. For a seal application, some level of volume swell is acceptable, since the expansion will serve to maintain a seal. However, the acceptable level of swell is dependent on the particular application of the elastomer product. It is known that excessive swell can lead to unacceptable extrusion of the elastomer beyond the sealed interface, where it becomes susceptible to damage. Also, since high swell is indicative of high solubility, there is a heightened potential for fluid to seep through the seal and into the environment. Plastics, on the other hand, are used primarily in structural applications, such as solid components, including piping and fluid containment. Volume change, especially in a rigid system, will create internal stresses that may negatively affect performance. In order to better understand and predict the compatibility for a given polymer type and fuel composition, an analysis based on Hansen solubility theory was performed for each plastic and elastomer material. From this study, the solubility distance was calculated for each polymer material and test fuel combination. Using the calculated solubility distance, the ethanol concentration associated with peak swell and overall extent of swell can be predicted for each polymer. The bulk of the material discussion centers on the plastic materials, and their compatibility with Fuel C, CE25a, CE50a, and CE85a. The next section of this paper focuses on the elastomer compatibility with the higher ethanol concentrations with comparison to results obtained previously for the lower ethanol levels. The elastomers were identical to those used in the earlier study. Hansen solubility theory is also applied to the elastomers to provide added interpretation of the results. The final section summarizes the performance of the metal coupons.

Air and oxy-fuel combustion behaviour of petcoke/lignite blends  

Science Journals Connector (OSTI)

The pyrolysis and combustion behaviour of a petroleum coke (petcoke), an indigenous lignite and their 70/30 wt.% blend in air and oxy-fuel conditions were investigated by using non-isothermal thermo-gravimetric method (TGA) coupled with Fourier transform infrared (FTIR) spectrometer. Blend samples were prepared by mixing lignite, which has low calorific value, high ash and moisture contents with petcoke that has high calorific value, low ash and moisture content, in the proportion of 70:30. Pyrolysis tests were carried out in nitrogen and carbon dioxide environments which are the main diluting gases of air and oxy-fuel environments, respectively. Pyrolysis curves of parent fuels and their blend reveal close resemblance up to 700 °C in both N2 and CO2 environments. At higher temperatures, further weight loss taking place in N2 and CO2 atmospheres is attributed to calcite decomposition and CO2-char gasification reaction, respectively. Gasification reaction leads to significant increase in CO and COS formation as observed in FTIR evolution profiles. Almost identical experimental and theoretical pyrolysis profiles of the blend samples show that there is no synergy between the parent fuels of the blend in both pyrolysis environments. Combustion experiments were carried out in four different atmospheres; air, oxygen-enriched air environment (30% O2–70% N2), oxy-fuel environment (21% O2–79% CO2) and oxygen-enriched oxy-fuel environment (30% O2–70% CO2). Combustion experiments show that replacing nitrogen in the gas mixture by the same concentration of CO2 leads to delay in combustion (lower maximum rate of weight loss and higher burnout temperatures). Overall comparison of derivative thermogravimetry (DTG) profiles shows that effect of oxygen content on combustion characteristics is more significant than that of diluting gas in the combustion environment. At elevated oxygen levels, profiles shift through lower temperature zone, peak and burnout temperatures decrease, weight loss rate increases significantly and complete combustion is achieved at lower temperatures and shorter times. Theoretical and experimental combustion profiles of the blend mainly display different trends, which indicate synergistic interactions between lignite and petcoke during their combustion in different environments.

An integrated video- and weight-monitoring system for the surveillance of highly enriched uranium blend down operations  

SciTech Connect (OSTI)

An integrated video-surveillance and weight-monitoring system has been designed and constructed for tracking the blending down of weapons-grade uranium by the US Department of Energy. The instrumentation is being used by the International Atomic Energy Agency in its task of tracking and verifying the blended material at the Portsmouth Gaseous Diffusion Plant, Portsmouth, Ohio. The weight instrumentation developed at the Oak Ridge National Laboratory monitors and records the weight of cylinders of the highly enriched uranium as their contents are fed into the blending facility while the video equipment provided by Sandia National Laboratory records periodic and event triggered images of the blending area. A secure data network between the scales, cameras, and computers insures data integrity and eliminates the possibility of tampering. The details of the weight monitoring instrumentation, video- and weight-system interaction, and the secure data network is discussed.

Effect of idling on fuel consumption and emissions of a diesel engine fueled by Jatropha biodiesel blends  

Science Journals Connector (OSTI)

Abstract An engine running at low load and low rated speed is said to be subject to high idling conditions, a mode which represents one of the major problems currently the transport industry is facing. During this time, the engine can not work at peak operating temperature. This leads to incomplete combustion and emissions level increase due to having fuel residues in the exhaust. Also, idling results in increase in fuel consumption. The purpose of this study is to evaluate fuel consumption and emissions parameters under high idling conditions when diesel blended with Jatropha curcas biodiesel is used to operate a diesel engine. Although biodiesel–diesel blends decrease carbon monoxide and hydrocarbon emissions, they increase nitrogen oxides emissions in high idling modes. Compared to pure diesel fuel, fuel consumption also increases under all high idling conditions for biodiesel–diesel blends, with a further increase occurring as blend percentage rises.

Impact of Biofuel Blending on Diesel Soot Oxidation: Implications for Aftertreatment  

SciTech Connect (OSTI)

Control strategies for diesel particulate filters (DPFs) remain one of the most important aspects of aftertreatment research and understanding the soot oxidation mechanism is key to controlling regeneration. Currently, most DPF models contain simple, first order heterogeneous reactions oxidation models with empirically fit parameters. This work improves the understanding of fundamental oxidation kinetics necessary to advance the capabilities of predictive modeling, by leading to better control over regeneration of the device. This study investigated the effects of blending soybean-derived biodiesel fuel on diesel particulate emissions under conventional combustion from a 1.7L direct injection, common rail diesel engine. Five biofuel blend levels were investigated and compared to conventional certification diesel for the nanostructure, surface chemistry and major constituents of the soluble organic fraction (SOF) of diesel particulate matter (PM), and the relationship between these properties and the particulate oxidation kinetics.

Polyethylene-supported polyvinylidene fluoride–cellulose acetate butyrate blended polymer electrolyte for lithium ion battery  

Science Journals Connector (OSTI)

The polyethylene (PE)-supported polymer membranes based on the blended polyvinylidene fluoride (PVDF) and cellulose acetate butyrate (CAB) are prepared for gel polymer electrolyte (GPE) of lithium ion battery. The performances of the prepared membranes and the resulting \\{GPEs\\} are investigated by scanning electron microscopy, electrochemical impedance spectroscopy, linear potential sweep, and charge–discharge test. The effect of the ratio of PVDF to CAB on the performance of the prepared membranes is considered. It is found that the GPE based on the blended polymer with PVDF:CAB = 2:1 (in weight) has the largest ionic conductivity (2.48 × 10?3 S cm?1) and shows good compatibility with anode and cathode of lithium ion battery. The LiCoO2/graphite battery using this GPE exhibits superior cyclic stability at room temperature, storage performance at elevated temperature, and rate performance.

Conformational free energy of melts of ring-linear polymer blends  

Science Journals Connector (OSTI)

The conformational free energy of ring polymers in a blend of ring and linear polymers is investigated using the bond-fluctuation model. Previously established scaling relationships for the free energy of a ring polymer are shown to be valid only in the mean-field sense, and alternative functional forms are investigated. It is shown that it may be difficult to accurately express the total free energy of a ring polymer by a simple scaling argument, or in closed form.

Ab initio study of phase transition of boron nitride between zinc-blende and rhombohedral structures  

SciTech Connect (OSTI)

Boron nitride has polymorphs such as zinc-blende (c-BN), wurtzite (w-BN), rhombohedral (r-BN), and graphite-like (h-BN) forms. We simulate the direct conversion of r-BN to c-BN through electronic excitation. In our calculation, the conversion is made possible by increasing the hole concentration to over 0.06/atom. This conversion should be experimentally possible by hole-doping via an electric double layer transistor (EDLT) or capacitor.

Novel Characterization of GDI Engine Exhaust for Gasoline and Mid-Level Gasoline-Alcohol Blends  

SciTech Connect (OSTI)

Gasoline direct injection (GDI) engines can offer improved fuel economy and higher performance over their port fuel-injected (PFI) counterparts, and are now appearing in increasingly more U.S. and European vehicles. Small displacement, turbocharged GDI engines are replacing large displacement engines, particularly in light-duty trucks and sport utility vehicles, in order for manufacturers to meet more stringent fuel economy standards. GDI engines typically emit the most particulate matter (PM) during periods of rich operation such as start-up and acceleration, and emissions of air toxics are also more likely during this condition. A 2.0 L GDI engine was operated at lambda of 0.91 at typical loads for acceleration (2600 rpm, 8 bar BMEP) on three different fuels; an 87 anti-knock index (AKI) gasoline (E0), 30% ethanol blended with the 87 AKI fuel (E30), and 48% isobutanol blended with the 87 AKI fuel. E30 was chosen to maximize octane enhancement while minimizing ethanol-blend level and iBu48 was chosen to match the same fuel oxygen level as E30. Particle size and number, organic carbon and elemental carbon (OC/EC), soot HC speciation, and aldehydes and ketones were all analyzed during the experiment. A new method for soot HC speciation is introduced using a direct, thermal desorption/pyrolysis inlet for the gas chromatograph (GC). Results showed high levels of aromatic compounds were present in the PM, including downstream of the catalyst, and the aldehydes were dominated by the alcohol blending.

In-cylinder pressure characteristics of a CI engine using blends of diesel fuel and methyl esters of beef tallow  

SciTech Connect (OSTI)

A Cummins N14-410 diesel engine was operated on 12 fuels produced by blending methyl tallowate, methyl soyate, and ethanol with no. 2 diesel fuel. Engine in-cylinder pressure data were used to evaluate engine performance. Peak cylinder pressures for each fuel blend at all engine speeds were lower than peak pressure for diesel fuel with the exception of the 80% diesel, 13% methyl tallowate, and 7% ethanol; and the 80% diesel, 6.5% methyl tallowate, 6.5% methyl soyate and 7% ethanol blends. The indicated mean effective pressure (IMEP) values for all fuel blends were less than for diesel fuel. The differences in IMEP values correlated with differences in power output of the engine. Similarly, maximum rates of pressure rise for most fuel blends were less than for diesel fuel. It was concluded that the fuel blends used in this study would have no detrimental long-term effects on engine performance, wear, and knock. 6 refs., 4 figs., 7 tabs.

Investigation on combustion characteristics of crude rice bran oil methyl ester blend as a heavy duty automotive engine fuel  

Science Journals Connector (OSTI)

In the present work, an attempt was made to test the suitability of crude rice bran oil methyl ester (CRBME) blend as a heavy duty automotive engine fuel. A four stroke, six cylinder direct injection 117.6 kW turbo-charged compression ignition (CI) engine was used for the work. The operation of the engine with CRBME blend showed that the peak pressure increased with lower maximum rate of pressure rise and maximum heat release rate with shorter delay period. Burning rate of the CRBME blend was slower and required a higher crank angle to complete the combustion cycle when compared to diesel. The brake thermal efficiency of the CRBME blend was lower than that of diesel at all speeds except at 2300rpm. As the measured combustion and performance parameters for CRBME blend differs only by a smaller magnitude when compared with diesel, this investigation ensures the suitability of the CRBME blend as fuel for heavy duty automotive engine without any design modifications [Received: August 12, 2010; Accepted: August 29, 2010

Recovery and Blend-Down Uranium for Beneficial use in Commercial Reactors - 13373  

SciTech Connect (OSTI)

In April 2001 the Department of Energy (DOE) and the Tennessee Valley Authority (TVA) signed an Interagency Agreement to transfer approximately 33 MT of off-specification (off-spec) highly enriched uranium (HEU) from DOE to TVA for conversion to commercial reactor fuel. Since that time additional surplus off-spec HEU material has been added to the program, making the total approximately 46 MT off-spec HEU. The disposition path for approximately half (23 MT) of this 46 MT of surplus HEU material, was down blending through the H-canyon facility at the Savannah River Site (SRS). The HEU is purified through the H-canyon processes, and then blended with natural uranium (NU) to form low enriched uranium (LEU) solution with a 4.95% U-235 isotopic content. This material was then transported to a TVA subcontractor who converted the solution to uranium oxide and then fabricated into commercial light water reactor (LWR) fuel. This fuel is now powering TVA reactors and supplying electricity to approximately 1 million households in the TVA region. There is still in excess of approximately 10 to 14 MT of off-spec HEU throughout the DOE complex or future foreign and domestic research reactor returns that could be recovered and down blended for use in either currently designed light water reactors, ?5% enriched LEU, or be made available for use in subsequent advanced 'fast' reactor fuel designs, ?19% LEU.

Role of dopant counter-anion functionality in polyaniline salts/blends and implications to morphology  

SciTech Connect (OSTI)

In this paper, wide and small angle X-ray scattering techniques (i.e., WAXS and SAXS) and light microscopy are used to characterize the influence of the dopant`s structure on the morphology of both polyaniline salt and blend. In an attempt to modify the morphology of the PANI-ES, the authors have evaluated a number of doping acids (i.e., methane sulfonic acid (HMSA), butane sulfonic acid (HBSA), dodecyl benzene sulfonic acid (HDBSA) and camphor sulfonic acid (HCSA)) that vary in size and polarity to better understand the role of the acid in PANI-ES`s morphology and the resulting electrical conductivity. These salts were solution blended with polycaprolactam using hexafluoro-2-propanol (HFIP) as a solvent. The other goal was to investigate the effect of the counter-anion structure on the nature of the phase separated PANI-ES network. The shape of the PANI-ES network in the host polycaprolactam has important implications on the nature of conduction behavior and the final electrical conductivity of the blend.

NMOG Emissions Characterization and Estimation for Vehicles Using Ethanol-Blended Fuels  

SciTech Connect (OSTI)

Ethanol is a biofuel commonly used in gasoline blends to displace petroleum consumption; its utilization is on the rise in the United States, spurred by the biofuel utilization mandates put in place by the Energy Independence and Security Act of 2007 (EISA). The United States Environmental Protection Agency (EPA) has the statutory responsibility to implement the EISA mandates through the promulgation of the Renewable Fuel Standard. EPA has historically mandated an emissions certification fuel specification that calls for ethanol-free fuel, except for the certification of flex-fuel vehicles. However, since the U.S. gasoline marketplace is now virtually saturated with E10, some organizations have suggested that inclusion of ethanol in emissions certification fuels would be appropriate. The test methodologies and calculations contained in the Code of Federal Regulations for gasoline-fueled vehicles have been developed with the presumption that the certification fuel does not contain ethanol; thus, a number of technical issues would require resolution before such a change could be accomplished. This report makes use of the considerable data gathered during the mid-level blends testing program to investigate one such issue: estimation of non-methane organic gas (NMOG) emissions. The data reported in this paper were gathered from over 600 cold-start Federal Test Procedure (FTP) tests conducted on 68 vehicles representing 21 models from model year 2000 to 2009. Most of the vehicles were certified to the Tier-2 emissions standard, but several older Tier-1 and national low emissions vehicle program (NLEV) vehicles were also included in the study. Exhaust speciation shows that ethanol, acetaldehyde, and formaldehyde dominate the oxygenated species emissions when ethanol is blended into the test fuel. A set of correlations were developed that are derived from the measured non-methane hydrocarbon (NMHC) emissions and the ethanol blend level in the fuel. These correlations were applied to the measured NMHC emissions from the mid-level ethanol blends testing program and the results compared against the measured NMOG emissions. The results show that the composite FTP NMOG emissions estimate has an error of 0.0015 g/mile {+-}0.0074 for 95% of the test results. Estimates for the individual phases of the FTP are also presented with similar error levels. A limited number of tests conducted using the LA92, US06, and highway fuel economy test cycles show that the FTP correlation also holds reasonably well for these cycles, though the error level relative to the measured NMOG value increases for NMOG emissions less than 0.010 g/mile.

Emissions and engine performance from blends of soya and canola methyl esters with ARB {number_sign}2 diesel in a DCC 6V92TA MUI engine  

SciTech Connect (OSTI)

A Detroit Diesel 6V92TA MUI engine was operated on several blends of EPA No. 2 diesel, California ARB No. 2 diesel, soya methyl ester (SME) and canola methyl ester (CME). Various fuels and fuel blend characteristics were determined and engine emissions from these fuels and blends were compared. Increasing percentages of SME and CME blended with either ARB or EPA diesels led to increased emissions of NO{sub x}, CO{sub 2} and soluble particulate matter. Also noted were reductions in total hydrocarbons, CO and insoluble particulate matter. Chassis dynamometer tests conducted on a 20/80 SME/ARB blend showed similar emissions trends. The data suggest that certain methyl ester/No. 2 diesel blends in conjunction with delays in engine timing and technologies that reduce the soluble fraction of particulate emissions merit further exploration as emissions reducing fuel options for North American mass transits (except in California, which mandates ARB diesel).

Optimization of combustion bowl geometry for the operation of kapok biodiesel – Diesel blends in a stationary diesel engine  

Science Journals Connector (OSTI)

Abstract The purpose of this research work is to optimize the combustion bowl geometry of a single cylinder stationary diesel engine for the effective operation of KME (kapok methyl ester) – diesel blends. Considering that the reported design modification would render the benefit of adaptation of higher blends of KME, in this study, two different combustion chamber geometries such as TRCC (trapezoidal combustion chamber) and TCC (toroidal combustion chamber) were chosen in addition to the convention design of HCC (hemispherical combustion chamber). In the experimental investigation, suitable blends such as B25 (25% KME + 75% diesel), B50 (50% KME + 50% diesel), B75 (75% KME + 25% diesel) and B100 (100% KME) were tested in a diesel engine with various combustion chamber geometries as mentioned above. Based on the results obtained from this study, TCC was shown to exhibit better performance and emission than TRCC and HCC for all test blends. Further, when compared to diesel, B25 and B50 were found to be the optimum blends with HCC and TCC, respectively, while TRCC seldom evinced better engine characteristics for any of the blends. Categorically, B50 showed a 5.2% increase in BTE (brake thermal efficiency) than diesel with TCC, whereas emissions such as CO (carbon monoxide) and smoke were reduced by 15.7% and 7.8%, respectively, with a comparable NOX (nitrogen oxides) emission with diesel. Similarly, combustion for B50 with TCC was found to be better than diesel, manifesting an increase in maximum heat release rate that that of diesel. Conclusively, from the experimental study, TCC was recognized as an ideal choice of combustion chamber design for the operation of blends up to B50 in a diesel engine.

Selection of best biodiesel blend for IC engines: an integrated approach with FAHP-TOPSIS and FAHP-VIKOR  

Science Journals Connector (OSTI)

The aim of this study is to select the best blend using multi-criteria decision-making (MCDM) technique. The six alternative fuel blends diesel, B20, B40, B60, B80 and B100 are prepared by varying the amount of diesel in biodiesel. Brake thermal efficiency (BTE), exhaust gas temperature (EGT), oxides of nitrogen (NOx), smoke, hydrocarbon (HC), carbon monoxide (CO) and carbon dioxide (CO2) are considered as evaluation criteria. A single cylinder, constant speed, direct injection diesel engine (4.4 kW) was used for exploratory analysis of evaluation criteria at different load conditions. Two models fuzzy analytical hierarchy process-technique for order preference by similarity to ideal solution (FAHP-TOPSIS) and VlseKriterijumska Optimizacija I Kompromisno Resenje (FAHP-VIKOR, in Serbian) are proposed to evaluate the best blend. Here, the FAHP is used to analyse the structure of best blend selection and to determine the weights of the criteria. The TOPSIS and VIKOR are used to obtain the final ranking of the blend.

Numerical study of the effect of oxygenated blending compounds on soot formation in shock tubes  

SciTech Connect (OSTI)

This numerical study deals with the influence of blends on the amount of soot formed in shock tubes, which were simulated by assuming a homogeneous plug flow reactor model. For this purpose, first, the reaction model used here was validated against experimental results previously obtained in the literature. Then, the soot volume fractions of various mixtures of methyl tert-butyl ether (MTBE)-benzene, isobutene-benzene, methanol-benzene, and ethanol-benzene diluted in argon were simulated and compared to the results of benzene-argon pyrolysis at 1721 K and 5.4 MPa. For MTBE, isobutene, methanol, and ethanol, small amounts of additives to benzene-argon mixtures promoted soot formation, for the shock tube model assumed, while higher concentrations of these additives led to smaller soot volume fractions in comparison to pure benzene-argon pyrolysis. The most significant soot promotion effect was found for the additives MTBE and isobutene. The channel for MTBE decomposition producing isobutene and methanol is very effective at temperatures beyond 1200 K. Thus, both MTBE-benzene and isobutene-benzene mixtures diluted in argon showed rather similar behavior in regard to soot formation. Special emphasis was directed toward the causes for the concentration-dependent influence of the blends on the amount of soot formed. Aromatic hydrocarbons and acetylene were identified as key gas-phase species that determine the trends in the formation of soot of various mixtures. From reaction flux analysis for phenanthrene, it was deduced that the combinative routes including phenyl species play a major role in forming PAHs, especially at early reaction times. It is found that the additives play an important role in providing material to grow side chains, such as by reaction channels including phenylacetylene or benzyl, which are confirmed to form aromatic hydrocarbons and thus to influence the amount of soot formed, particularly when the concentrations of the blends are increased.

Study on ash deposition under oxyfuel combustion of coal/biomass blends  

Science Journals Connector (OSTI)

Combustion in an O2/CO2 mixture (oxyfuel) has been recognized as a promising technology for CO2 capture as it produces a high CO2 concentration flue gas. Furthermore, biofuels in general contribute to CO2 reduction in comparison with fossil fuels as they are considered CO2 neutral. Ash formation and deposition (surface fouling) behavior of coal/biomass blends under O2/CO2 combustion conditions is still not extensively studied. Aim of this work is the comparative study of ash formation and deposition of selected coal/biomass blends under oxyfuel and air conditions in a lab scale pulverized coal combustor (drop tube). The fuels used were Russian and South African coals and their blends with Shea meal (cocoa). A horizontal deposition probe, equipped with thermocouples and heat transfer sensors for on line data acquisition, was placed at a fixed distance from the burner in order to simulate the ash deposition on heat transfer surfaces (e.g. water or steam tubes). Furthermore, a cascade impactor (staged filter) was used to obtain size distributed ash samples including the submicron range at the reactor exit. The deposition ratio and propensity measured for the various experimental conditions were higher in all oxyfuel cases. The SEM/EDS and ICP analyses of the deposit and cascade impactor ash samples indicate K interactions with the alumina silicates and to a smaller extend with Cl, which was all released in the gas phase, in both the oxyfuel and air combustion samples. Sulfur was depleted in both the air or oxyfuel ash deposits. S and K enrichment was detected in the fine ash stages, slightly increased under air combustion conditions. Chemical equilibrium calculations were carried out to facilitate the interpretation of the measured data; the results indicate that temperature dependence and fuels/blends ash composition are the major factors affecting gaseous compounds and ash composition rather than the combustion environment, which seems to affect the fine ash (submicron) ash composition, and the ash deposition mechanisms.

Preliminary report on blending strategies for inert-matrix fuel recycling in LWRs.  

SciTech Connect (OSTI)

Various recycle strategies have been proposed to manage the inventory of transuranics in commercial spent nuclear fuel (CSNF), with a particular goal of increasing the loading capacity of spent fuel and reprocessing wastes in the Yucca Mountain repository. Transuranic recycling in commercial LWRs can be seen as a viable means of slowing the accumulation of transuranics in the nationwide CSNF stockpile. Furthermore, this type of approach is an important first step in demonstrating the benefits of a nuclear fuel cycle which incorporates recycling, such as envisioned for Generation-IV reactor systems under development. Recycling strategies of this sort are not proposed as an attempt to eliminate the need of a geologic nuclear waste repository, but as a means to enhance the usefulness of the repository currently under construction in the U.S., perhaps circumventing the need for a second facility. A US-DOE Secretarial recommendation on the need for the construction of a second geologic repository is required by 2010. The Advanced Fuel Cycle Initiative (AFCI) has supported a breadth of work to evaluate the ideal transuranic separation and recycle strategy. Previous AFCI studies of LWR-based transmutation have considered the benefits of homogeneously recycling plutonium, plutonium and neptunium, and all transuranic (TRU) species. A study of a wide range of hypothetical separation schemes (Pu, Pu+Np, Pu+Np+Am, etc.) with multi-recycling has also been performed, focusing on the proliferation resistance of the various fuel cycles and fuel handling issues. The direct recycle of the recovered TRU from spent inert-matrix fuel (IMF) into new IMF was found to be quite limited due to the rapid burndown of the fissile plutonium. The IMF is very effective at destroying the fissile fraction of the TRU with destruction rates in excess of 80% of the fissile material without recycling the IMF. Blending strategies have been proposed to mitigate the rapid burndown of the fissile plutonium by mixing high fissile feed from new sources (e.g., spent UO{sub 2} pins) with the low fissile material recovered from the recycled transmutation fuel. The blending of the fuels is anticipated to aid the multi-recycle of the transuranics. A systematic study of blending strategies (for both IMF and MOX) has been initiated and is currently ongoing. This work extends the previous study that considered separation strategies for plutonium, neptunium, and americium recycling in MOX, CORAIL, and IMF{sub 6} by considering blending schemes and approach to continuous recycle. Plutonium and americium are recycled in order to reduce the intermediate term (100 to 1500 years after spent fuel irradiation) decay heat of the disposed waste which accounts for the bulk of the repository heating. Since the long-term released dose from the repository is dominated by neptunium, it is sensible to consume it by transmutation in a reactor, as well. Curium accounts for {approx}0.6% of the TRU mass in spent UO{sub 2} fuel ({approx}0.008% of the heavy metal), but does constitute significantly higher fractions in spent transmutation fuels. This initial evaluation will focus on blending strategies for the multirecycling of Pu+Np+Am. The impact of curium recycle will be investigated as part of the systematic study of blending strategies. The initial study focuses on understanding a simple strategy for IMF recycle and blending. More complex strategies (i.e., heterogeneous assemblies) will be evaluated later in the year, including enriched uranium support options. Currently, a preliminary study of a serial blending strategy has been performed in order to evaluate the impact of blending on the performance of the IMF recycle and to evaluate the potential for continuous or infinite recycle. The continuous recycle of Pu+Np+Am in IMF would allow for complete destruction of all heat contributing actinides in the same LWRs that originally produced them. The only transuranics sent to the repository would be those lost in reprocessing and curium if it is not eventually recycled.

The Use of Triangular-Shaped PV Arrays to Better Blend into Historical Structures  

Broader source: Energy.gov [DOE]

When considering the installation of a solar PV array on a designated historical structure, placement of each solar panel requires extra attention to aesthetic considerations. If the solar array cannot be installed behind the structure or “hidden” on a roof plane that is not visible from the public street or sidewalk, it can sometimes be installed as an architectural feature that blends into the historical structure. One way to do this is to utilize triangular-shaped PV panels that conform with the building’s roof lines.

Exhaust particle characterization for lean and stoichiometric DI vehicles operating on ethanol-gasoline blends  

SciTech Connect (OSTI)

Gasoline direct injection (GDI) engines can offer better fuel economy and higher performance over their port fuel-injected (PFI) counterparts, and are now appearing in increasingly more U.S. and European vehicles. Small displacement, turbocharged GDI engines are replacing large displacement engines, particularly in light-duty trucks and sport utility vehicles, in order for manufacturers to meet the U.S. fuel economy standards for 2016. Furthermore, lean-burn GDI engines can offer even higher fuel economy than stoichiometric GDI engines and have overcome challenges associated with cost-effective aftertreatment for NOx control. Along with changes in gasoline engine technology, fuel composition may increase in ethanol content beyond the current 10% due to the recent EPA waiver allowing 15% ethanol. In addition, the Renewable Fuels Standard passed as part of the 2007 Energy Independence and Security Act (EISA) mandates the use of biofuels in upcoming years. GDI engines are of environmental concern due to their high particulate matter (PM) emissions relative to port-fuel injected (PFI) gasoline vehicles; widespread market penetration of GDI vehicles may result in additional PM from mobile sources at a time when the diesel contribution is declining. In this study, we characterized particulate emissions from a European certified lean-burn GDI vehicle operating on ethanol-gasoline blends. Particle mass and particle number concentration emissions were measured for the Federal Test Procedure urban driving cycle (FTP 75) and the more aggressive US06 driving cycle. Particle number-size distributions and organic to elemental carbon ratios (OC/EC) were measured for 30 MPH and 80 MPH steady-state operation. In addition, particle number concentration was measured during wide open throttle accelerations (WOTs) and gradual accelerations representative of the FTP 75. Fuels included certification gasoline and 10% (E10) and 20% (E20) ethanol blends from the same supplier. The particle mass emissions were approximately 3 and 7 mg/mile for the FTP75 and US06, respectively, with lower emissions for the ethanol blends. The data are compared to a previous study on a U.S.-legal stoichiometric GDI vehicle operating on the same ethanol blends. The lean-burn GDI vehicle emitted a higher number of particles, but had an overall smaller average size. Particle number per mile decreased with increasing ethanol content for the transient tests. For the 30 and 80 mph tests, particle number concentration decreased with increasing ethanol content, although the shape of the particle size distribution remained the same. Engine-out OC/EC ratios were highest for the stoichiometric GDI vehicle with E20, but tailpipe OC/EC ratios were similar for all vehicles.

Physical Components, Coordinate Components, and the Speed of Light  

E-Print Network [OSTI]

For generalized coordinate systems, the numerical values of vector and tensor components do not generally equal the physical values, i.e., the values one would measure with standard physical instruments. Hence, calculating physical components from coordinate components is important for comparing experiment with theory. Surprisingly, however, this calculational method is not widely known among physicists, and is rarely taught in relativity courses, though it is commonly employed in at least one other field (applied mechanics.) Different derivations of this method, ranging from elementary to advanced level, are presented. The result is then applied to clarify the oftentimes confusing issue of whether or not the speed of light in non-inertial frames is equal to c.

Automated cleaning of electronic components  

SciTech Connect (OSTI)

Environmental and operator safety concerns are leading to the elimination of trichloroethylene and chlorofluorocarbon solvents in cleaning processes that remove rosin flux, organic and inorganic contamination, and particulates from electronic components. Present processes depend heavily on these solvents for manual spray cleaning of small components and subassemblies. Use of alternative solvent systems can lead to longer processing times and reduced quality. Automated spray cleaning can improve the quality of the cleaning process, thus enabling the productive use of environmentally conscious materials, while minimizing personnel exposure to hazardous materials. We describe the development of a prototype robotic system for cleaning electronic components in a spray cleaning workcell. An important feature of the prototype system is the capability to generate the robot paths and motions automatically from the CAD models of the part to be cleaned, and to embed cleaning process knowledge into the automatically programmed operations.

Morphological origin for the stratification of P3HT:PCBM blend film studied by neutron reflectometry  

SciTech Connect (OSTI)

Understanding the origin for the film stratification of electron donor/acceptor blend is crucial for high efficiency organic photovoltaic cell. In this study, P3HT:PCBM blend is deposited onto hydrophilic and hydrophobic substrate to examine the film stratifications. The neutron reflectivity results show that, on the different surfaces, PCBM diffuses toward the two interfacial regions in an identical fashion during thermal annealing. This evidences that the film stratification is not affected by the substrates. Instead, since P3HT remains more amorphous in the interfacial regions and PCBM is miscible with amorphous P3HT, PCBM preferentially diffuses to the interfacial regions, resulting in the stratification.

Narrow spectral linewidth of single zinc-blende GaN/AlN self-assembled quantum dots  

SciTech Connect (OSTI)

We study by microphotoluminescence the optical properties of single self-assembled zinc-blende GaN/AlN quantum dots grown by plasma-assisted molecular beam epitaxy. As opposed to previous reports, the high quality of such zinc-blende GaN quantum dots allows us to evidence a weak acoustic phonon sideband as well as a limited spectral diffusion. As a result, we report on resolution-limited quantum dot linewidths as narrow as 500 ± 50 ?eV. We finally confirm the fast radiative lifetime and high-temperature operation of such quantum dots.

Role of dopant counter-anion functionality in polyaniline salts/blends and implications to morphology  

SciTech Connect (OSTI)

Polyanilines are of particular current interest primarily due to their relative ease of synthesis, low cost and stable conductivity in air. The insulating, polyaniline emeraldine base (PANI-EB) form becomes electrically conducting by preferential protonation or doping the imine nitrogen sites to yield an electrically conducting polyaniline emeraldine salt (PANI-ES). In this paper, wide and small angle X-ray scattering techniques (i.e., WAXS and SAXS) and light microscopy are used to characterize the influence of the dopant`s structure on the morphology of both polyaniline salt and blend. In an attempt to modify the morphology of the PANI-ES, the authors have evaluated a number of doping acids (i.e., methane sulfonic acid (HMSA), butane sulfonic acid (HBSA), dodecyl benzene sulfonic acid (HDBSA) and camphor sulfonic acid (HCSA)) that vary in size and polarity to better understanding the role of the acid in PANI-ES`s morphology and the resulting electrical conductivity. The other goal was to investigate the effect of the counter-anion structure on the nature of the phase separated PANI-ES network. The shape of the PANI-ES network in the host polycaprolactam has important implications on the nature of conduction behavior and the final electrical conductivity of the blend.

Relationship between thermal behaviour of lignocellulosic components and properties of biomass  

Science Journals Connector (OSTI)

Abstract Five different biomass samples were selected for this study, including miscanthus, distillers dried grain (DDG), wheat shorts, wheat straw and UK wood. These samples were thermochemically treated to alter the lignin, cellulose and hemicellulose composition. Thermogravimetric tests were carried out on these samples to determine thermal behaviours of biomass and its individual lignocellulosic components. The relationship between thermal behaviour of biomass and its corresponding lignocellulosic composition was revealed. The reliability of this relationship was proved by thermogravimetric analysis of samples of artificial biomass prepared by mixing commercially obtained lignin, cellulose and hemicellulose at various blending ratios. It is shown that actual biomass profiles can be predicted with some degree of accuracy based on the lignocellulosic composition.

Relationship between the technical parameters of cokes produced from blends of three Polish coals of different coking ability  

Science Journals Connector (OSTI)

The demand for metallurgical coke for blast furnaces is forcing the coking industry to look for new sources of coking coals. The physical and chemical parameters of coals used in coking blends determine the quality (reactivity and strength) of the finished cokes. This study examines the technical properties of the cokes produced from various blends of three Polish coals with different coking. These coals were collected from three mines: Zofiówka, Szczyg?owice, and Krupi?ski (Upper Silesian Coal Basin, Poland). The coal charges were coked in the laboratory scale, at temperatures of up to 1000 °C, in an inert atmosphere. The coke reactivity (index CRI) and the coke strength after reaction (CSR) were measured and correlated to the properties of parent coals using statistical analysis. The result of this study shows strong relationships between the concentration of the best coking coal (Zofiówka) in the blend and the CRI and CSR of the resulting coke. The CRI and CSR parameters for cokes obtained from single coals and from their blends show the additive character. This study also confirms the linear relationship between CRI and CSR parameters of the cokes.

Evaluation of dry-solids-blend material source for grouts containing 106-AN waste: September 1990 progress report  

SciTech Connect (OSTI)

Stabilization/solidification (S/S) is the most widely used technology for the treatment and ultimate disposal of both radioactive and chemically hazardous wastes. Such technology is being utilized in a Grout Treatment Facility (GTF) by the Westinghouse Hanford Company (WHC) for the disposal of various wastes, including 106-AN wastes, located on the Hanford Reservation. The WHC personnel have developed a grout formula for 106-AN disposal that is designed to meet stringent performance requirements. This formula consists of a dry-solids blend containing 40 wt % limestone, 28 wt % granulated blast furnace slag (BFS), 28 wt % ASTM Class F fly ash, and 4 wt % Type I-II-LA Portland cement. The blend is mixed with 106-AN waste at a ratio of 9 lb of dry-solids blend per gallon of waste. This report documents progress made to date on efforts at Oak Ridge National Laboratory (ORNL) in support of WHC`s Grout Technology Program to assess the effects of the source of the dry-solids-blend materials on the resulting grout formula.

Properties and performance of cotton seed oil–diesel blends as a fuel for compression ignition engines  

Science Journals Connector (OSTI)

This paper presents the evaluation of properties of straight vegetable cotton seed oil (CSO) and its blends with diesel fuel in various proportions to evaluate the performance and emission characteristics of a single cylinder compression ignition (CI) engine at constant speed of 1500 rev ? min . Diesel and CSO oil fuel blends (10% 30% 50% and 70%) were used to conduct engine performance and smoke emission tests at varying loads of 0% 20% 40% 60% 80% and 100% of full load in addition to their straight CSO and diesel fuel. The performance parameters of brake specific energy consumption (BSFC) brake thermal efficiency (BTE) mechanical efficiency (ME) exhaust gas temperature (EGT) and exhaust emission (smoke) were evaluated to find the optimum CSO and diesel fuel blend. From the experimental results the CSO10D90 blend fuel showed 3.7% reduction in BSFC 1.7% increase in BTE 6.7% increase in ME and 21.7% reduction in the smoke emissions in comparison with conventional diesel operated engine. Finally it is concluded that CSO10D90 can be used straight away in CI engines without any major modifications to the engine as it showed good performance and improved emission compared to all other fuels tested for the entire range of engine operation in comparison with diesel.

Selective catalytic reduction of nitric oxide with ethanol/gasoline blends over a silver/alumina catalyst  

SciTech Connect (OSTI)

Lean gasoline engines running on ethanol/gasoline blends and equipped with a silver/alumina catalyst for selective catalytic reduction (SCR) of NO by ethanol provide a pathway to reduced petroleum consumption through both increased biofuel utilization and improved engine efficiency relative to the current stoichiometric gasoline engines that dominate the U.S. light duty vehicle fleet. A pre-commercial silver/alumina catalyst demonstrated high NOx conversions over a moderate temperature window with both neat ethanol and ethanol/gasoline blends containing at least 50% ethanol. Selectivity to NH3 increases with HC dosing and ethanol content in gasoline blends, but appears to saturate at around 45%. NO2 and acetaldehyde behave like intermediates in the ethanol SCR of NO. NH3 SCR of NOx does not appear to play a major role in the ethanol SCR reaction mechanism. Ethanol is responsible for the low temperature SCR activity observed with the ethanol/gasoline blends. The gasoline HCs do not deactivate the catalyst ethanol SCR activity, but they also do not appear to be significantly activated by the presence of ethanol.

This paper describes an application of hybrid MCDM technique for the selection of optimum blend in fish oil biodiesel among the six alternative fuel blends diesel, B20, B40, B60, B80 and B100 which is prepared by varying the amount of diesel with biodiesel. Brake thermal efficiency (BTE), exhaust gas temperature (EGT), oxides of nitrogen (NOx), smoke, hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (CO2), ignition delay (ID), combustion duration (CD) and maximum rate of pressure rise (MRPR) are considered as evaluation criteria. A single cylinder, constant speed and direct injection diesel engine with a rated output of 4.4 kW was used for exploratory analysis of evaluation criteria at different load conditions. The proposed model, fuzzy analytical hierarchy process (FAHP) is integrated with elimination et and choice translating reality (ELECTRE) to evaluate the optimum blend. Here the FAHP is used to determine the relative weights of the criteria, whereas ELECTRE is used for obtaining the final ranking of alternative blends.

Nuclear component horizontal seismic restraint  

DOE Patents [OSTI]

A nuclear component horizontal seismic restraint. Small gaps limit horizontal displacement of components during a seismic occurrence and therefore reduce dynamic loadings on the free lower end. The reactor vessel and reactor guard vessel use thicker section roll-forged rings welded between the vessel straight shell sections and the bottom hemispherical head sections. The inside of the reactor guard vessel ring forging contains local vertical dovetail slots and upper ledge pockets to mount and retain field fitted and installed blocks. As an option, the horizontal displacement of the reactor vessel core support cone can be limited by including shop fitted/installed local blocks in opposing alignment with the reactor vessel forged ring. Beams embedded in the wall of the reactor building protrude into apertures in the thermal insulation shell adjacent the reactor guard vessel ring and have motion limit blocks attached thereto to provide to a predetermined clearance between the blocks and reactor guard vessel ring.

Fusion-component lifetime analysis  

SciTech Connect (OSTI)

A one-dimensional computer code has been developed to examine the lifetime of first-wall and impurity-control components. The code incorporates the operating and design parameters, the material characteristics, and the appropriate failure criteria for the individual components. The major emphasis of the modeling effort has been to calculate the temperature-stress-strain-radiation effects history of a component so that the synergystic effects between sputtering erosion, swelling, creep, fatigue, and crack growth can be examined. The general forms of the property equations are the same for all materials in order to provide the greatest flexibility for materials selection in the code. The individual coefficients within the equations are different for each material. The code is capable of determining the behavior of a plate, composed of either a single or dual material structure, that is either totally constrained or constrained from bending but not from expansion. The code has been utilized to analyze the first walls for FED/INTOR and DEMO and to analyze the limiter for FED/INTOR.

Production and characterization of natural rubber–Ca/P blends for biomedical purposes  

Science Journals Connector (OSTI)

Abstract This study presents the development of natural rubber–Ca/P blends, as promising candidates for biomedical purposes. The specific objective was the incorporation of Ca/P into a natural rubber polymeric matrix. Ca/P crystalline phases were synthesized by the sol–gel method and the polymeric matrices were produced using natural rubber extracted from latex of the Hevea brasiliensis. The shape and size of natural rubber particles present in the NR membrane, as well as, the way the Ca/P powder grains aggregate in the polymeric matrix were investigated, giving information about the interactions between the Ca/P and the natural rubber particles. Confocal fluorescence scanning microscopy measurements allowed us to propose a structure where the Ca/P grains are surrounded by natural rubber particles. This structure may mediate Ca2 + release for tissue regeneration. The system investigated may open new horizons for development of a bandage which provides the controlled-release of biomaterials.

Detailed chemical kinetic mechanism for the oxidation of biodiesel fuels blend surrogate.  

SciTech Connect (OSTI)

Detailed chemical kinetic mechanisms were developed and used to study the oxidation of two large unsaturated esters: methyl-5-decenoate and methyl-9-decenoate. These models were built from a previous methyl decanoate mechanism and were compared with rapeseed oil methyl esters oxidation experiments in a jet stirred reactor. A comparative study of the reactivity of these three oxygenated compounds was performed and the differences in the distribution of the products of the reaction were highlighted showing the influence of the presence and the position of a double bond in the chain. Blend surrogates, containing methyl decanoate, methyl-5-decenoate, methyl-9-decenoate and n-alkanes, were tested against rapeseed oil methyl esters and methyl palmitate/n-decane experiments. These surrogate models are realistic kinetic tools allowing the study of the combustion of biodiesel fuels in diesel and homogeneous charge compression ignition engines.

Susceptibility of Aluminum Alloys to Corrosion in Simulated Fuel Blends Containing Ethanol  

SciTech Connect (OSTI)

The compatibility of aluminum and aluminum alloys with synthetic fuel blends comprised of ethanol and reference fuel C (a 50/50 mix of toluene and iso-octane) was examined as a function of water content and temperature. Commercially pure wrought aluminum and several cast aluminum alloys were observed to be similarly susceptible to substantial corrosion in dry (< 50 ppm water) ethanol. Corrosion rates of all the aluminum materials examined was accelerated by increased temperature and ethanol content in the fuel mixture, but inhibited by increased water content. Pretreatments designed to stabilize passive films on aluminum increased the incubation time for onset of corrosion, suggesting film stability is a significant factor in the mechanism of corrosion.

Performance of a spark ignition engine fueled with methanol or methanol-gasoline blends  

SciTech Connect (OSTI)

Engine torque and specific energy consumption of an automotive engine were studied under steady state condition using gasoline, methanol gasoline blends and straight methanol as fuel. At first the engine was run without any modification. Next the diameters of metering orifices in carburetor were modified to give the same excess air factor regardless of fuel type under each fixed engine operating condition. Finally the engine was run with 15% mixture methanol in gasoline by volume using the carburetor modified to have approximately 10% larger fuel flow area than the production carburetor. From the results of this study the effects of using methanol on engine torque and specific energy consumption can be explained on the basis of change in stoichiometry caused by the use of methanol.

PUBLIC AND REGULATORY ACCEPTANCE OF BLENDING OF RADIOACTIVE WASTE VS DILUTION  

SciTech Connect (OSTI)

On April 21, 2009, the Energy Facilities Contractors Group (EFCOG) Waste Management Working Group (WMWG) provided a recommendation to the Department of Energy's Environmental Management program (DOE-EM) concerning supplemental guidance on blending methodologies to use to classify waste forms to determine if the waste form meets the definition of Transuranic (TRU) Waste or can be classified as Low-Level Waste (LLW). The guidance provides specific examples and methods to allow DOE and its Contractors to properly classify waste forms while reducing the generation of TRU wastes. TRU wastes are much more expensive to characterize at the generator's facilities, ship, and then dispose at the Waste Isolation Pilot Plant (WIPP) than Low-Level Radioactive Waste's disposal. Also the reduction of handling and packaging of LLW is inherently less hazardous to the nuclear workforce. Therefore, it is important to perform the characterization properly, but in a manner that minimizes the generation of TRU wastes if at all possible. In fact, the generation of additional volumes of radioactive wastes under the ARRA programs, this recommendation should improve the cost effective implementation of DOE requirements while properly protecting human health and the environment. This paper will describe how the message of appropriate, less expensive, less hazardous blending of radioactive waste is the 'right' thing to do in many cases, but can be confused with inappropriate 'dilution' that is frowned upon by regulators and stakeholders in the public. A proposal will be made in this paper on how to communicate this very complex and confusing technical issue to regulatory bodies and interested stakeholders to gain understanding and approval of the concept. The results of application of the proposed communication method and attempt to change the regulatory requirements in this area will be discussed including efforts by DOE and the NRC on this very complex subject.

Analysis of synthetic cannabinoids in herbal blends by means of nano-liquid chromatography  

Science Journals Connector (OSTI)

In this study, a rapid and simultaneous separation of 12 synthetic cannabinoids and ?9-tetrahydrocannabinol (?9-THC) in herbal blends was obtained by means of nano-liquid chromatography (nano-LC). The nano-LC experiments were performed in a 100 ?m i.d. capillary column packed with Cogent® bidentate C18 silica particles for 25.0 cm. All compounds were resolved using an isocratic elution mode in less than 30 min. A mobile phase containing ACN/MeOH/H2O/formic acid 69/5/25/1 (v/v/v/v) was employed for the chromatographic separation. The developed analytical method was validated in terms of precision, linearity, sensitivity and accuracy. Under optimal nano-LC–UV conditions, the resulting RSD percentages for intra-day and inter-day repeatability, related to retention time and peak area, were below 2.98 and 6.40%, respectively. Limits of detection and quantification were 0.2 and 0.5 ?g/mL, respectively, for all the studied compounds. Linearity was assessed in the concentration range of interest for all analytes with determination coefficients r2 ? 0.9975. The method was then applied to the determination of synthetic cannabinoids in herbal blends. Quantitative analyses of the cannabimimetic compounds in six products showed that there was a wide difference in the concentration of the studied compounds among different products. Further, the nano-LC system was coupled with a mass spectrometer measuring the MS and MS–MS spectra to unequivocally identify the cannabinoids present in smoking mixtures.

Experimental study on the performance, emission and combustion characteristics of rubber seed oil-diesel blends in a DI diesel engine  

Science Journals Connector (OSTI)

In the present work, experiments have been carried out to assess the suitability of rubber seed oil and its blends with diesel in a diesel engine. Tests were conducted with different blends of R80-D20 (80% of rubber seed oil and 20% of diesel by volume) and R70-D30 (70% of rubber seed oil and 30% of diesel by volume). Experimental results indicate that the brake thermal efficiency increases from 26.5% to 27.7% with the optimum blend of R70-D30. There is a reduction in emissions is also observed except NOx level at all loads. Smoke emission reduces drastically from 6.1 to 4.7 BSU. Combustion parameters indicated a decrease in ignition delay and combustion duration compared with neat RSO. This will also contribute to higher heat release rate in the premixed combustion phase. Current investigations reveal that the performance of R70-D30 blend is closer to diesel.

Characteristics of the performance and emissions of a HSDI diesel engine running with cottonseed oil or its methyl ester and their blends with diesel fuel  

Science Journals Connector (OSTI)

An experimental study has been conducted to evaluate the use of various blends of cottonseed oil or its methyl ester (bio-diesel) with diesel fuel, in blend ratios from 10/90 up to 100/0, in a fully instrumented, four-stroke, High Speed Direct Injection (HSDI), Ricardo/Cussons 'Hydra' diesel engine. The tests were conducted using each of the above fuel blends or neat fuels, with the engine working at a medium and a high load. Volumetric fuel consumption, exhaust smokiness and exhaust-regulated gas emissions such as nitrogen oxides, carbon monoxide and unburnt hydrocarbons were measured. The differences in the performance and exhaust emissions from the baseline operation of the engine, that is, when working with neat diesel fuel, were determined and compared, as well as the differences between cottonseed oil or its methyl ester and their blends. Theoretical aspects of diesel engine combustion were used to aid the correct interpretation of the engine behaviour.

Effect of different percentages of biodiesel–diesel blends on injection, spray, combustion, performance, and emission characteristics of a diesel engine  

Science Journals Connector (OSTI)

Abstract A comparative study of effect of different biodiesel–diesel blends (B5, B10, B15, B20, B25, B50 and B100) on injection, spray, combustion, performance, and emissions of a direct injection diesel engine at constant speed (1500 rpm) was carried out. The penetration distance increased with increase in percentage of biodiesel in diesel due to enhanced in-line fuel pressure. The simulation results indicate the spray penetration with biodiesel–diesel blend up to B15 does not lead to wall impingement but B20 is to be a critical limit of wall impingement (within uncertainty ±1.3%). However, it is observed clearly from the simulation results that probability of wall impingement is more with higher blends (B25, B50 and B100). The ignition delay period decreased with all biodiesel blends due to higher cetane number resulting in less rate of pressure rise and the smooth engine running operation. The engine torque does not change significantly with biodiesel–diesel blends up to 20% (B20). However, the torque reduction is about 2.7% with B100 at the rated load. Carbon monoxide (CO), hydrocarbon (HC) and smoke emissions decreased with all biodiesel–diesel blends. However, oxides of nitrogen (NOx) emission increased in the range of 1.4–22.8% with all biodiesel–diesel blends at rated load due to oxygenated fuel, automatic advance in dynamic injection timing (DIT), higher penetration and higher in-cylinder temperature. A notable conclusion emerged from this study is the optimum biodiesel–diesel blend based on no wall impingement (B15: 0% and B20 ±1.3% uncertainty limit) and increase in \\{NOx\\} emission (B15: 4.1% and B20: 15.6%) in a conventional (unmodified) diesel engine is up to B15.

Combustion analysis of a direct injection diesel engine when fuelled with sunflower methyl ester and its diesel blends  

Science Journals Connector (OSTI)

Uncertainty in the availability of petroleum-based fuels in the near future and stringent pollution norms have triggered a search for renewable and clean-burning fuels. The use of vegetable oil as an alternative fuel has for long been in the pipeline, but its direct use has been limited because of its higher viscosity. In this work, sunflower oil was taken as feedstock and the feasibility of sunflower oil methyl ester (SFME) as an alternative fuel for diesel engines was investigated. Tests were conducted in a 4.4 kW, single cylinder, naturally aspirated direct injection diesel engine. It was observed that the premixed combustion phase of SFME and its blends were less intense compared with diesel oil. In addition, it was observed that SFME and its blends had slightly lower thermal efficiency and lower tailpipe emissions than diesel oil.

The comparative analysis of diesel engine combustion and emission parameters fuelled with palm oil methyl esters and its diesel blends  

Science Journals Connector (OSTI)

In this work, the combustion and emission characteristics of a direct injection compression ignition engine fuelled with diesel-Palm Oil Methyl Ester (POME) blends are investigated. This study shows that the ignition delay decreases with increase in the POME addition. The maximum rate of pressure rise and maximum rate of heat release decreases with increase in POME addition at all loads. As the percentage of POME in the blend increases, the crank angle at which the maximum rate of heat release takes place advances. The brake thermal efficiency decreases with increase in POME addition. The unburned hydrocarbon, carbon monoxide and soot intensity decreases, while nitrogen oxides (NOx) increase with increase in POME addition. [Received: April 4, 2008; Accepted: November 24, 2008

Effect of simultaneous electrical and thermal treatment on the performance of bulk heterojunction organic solar cell blended with organic salt  

SciTech Connect (OSTI)

This work presents the influence of simultaneous electrical and thermal treatment on the performance of organic solar cell blended with organic salt. The organic solar cells were composed of indium tin oxide as anode, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]: (6,6)-phenyl-C61 butyric acid methyl ester: tetrabutylammonium hexafluorophosphate blend as organic active layer and aluminium as cathode. The devices underwent a simultaneous fixed-voltage electrical and thermal treatment at different temperatures of 25, 50 and 75 °C. It was found that photovoltaic performance improved with the thermal treatment temperature. Accumulation of more organic salt ions in the active layer leads to broadening of p-n doped regions and hence higher built-in electric field across thin intrinsic layer. The simultaneous electrical and thermal treatment has been shown to be able to reduce the electrical treatment voltage.

Effect of palm methyl ester-diesel blends performance and emission of a single-cylinder direct-injection diesel engine  

Science Journals Connector (OSTI)

The purpose of this study is to investigate engine performance and exhaust emission when using several blends of neat palm oil methyl ester (POME) with conventional diesel (D2) in a small direct injection diesel engine and to compare the outcomes to that of the D2 fuel. Engine performances exhaust emissions and some other important parameters were observed as a function of engine load and speed. In addition the effect of modifying compression ratio was also carried out in this study. From the engine experimental work neat and blended fuels behaved comparably to diesel (D2) in terms of fuel consumption thermal efficiency and rate of heat released. Smoke density showed better results than that emitted by D2 operating under similar conditions due to the presence of inherited oxygen and lower sulphur content in the biofuel and its blends. The emissions of CO CO2 and HC were also lower using blended mixtures and in its neat form. However NOx concentrations were found to be slight higher for POME and its blends and this was largely due to higher viscosity of POME and possibly the presence of nitrogen in the palm methyl ester. General observation indicates that biofuel blends can be use without many difficulties in this type of engine but for optimized operation minor modifications to the engine and its auxiliaries are required.

A novel technique for assessing the coking potential of coals/coal blends for non-recovery coke making process  

Science Journals Connector (OSTI)

Abstract In an effort to broaden the scope of coal selection, the authors have developed a novel procedure based on a coefficient, named as Composite Coking Potential (CCP). CCP value assesses the suitability of a coal/coal blend for producing coke of desired quality; measured by the parameter coke strength after reaction (CSR). The coking potential takes into account of various properties of the coals and their proportions in a given coal blend and convert them into a single value. This technique is having advantage since each of these parameters represents different aspects of the coking phenomena along with inter dependence of some of these parameters also exists. This makes the coal selection process extremely difficult and in majority of the cases, decision is taken based on experience. In this investigation, CCP model has been used for selecting the least expensive coal blends which will comply with the minimum coke quality requirements of blast furnace. The study confirms the inter relations between the CCP and the hot strength of coke i.e. CSR. Actual plant data of a non-recovery coke oven have been used for developing and validation of the model. The technique was successfully used in identifying cheaper coals for producing coke with desired quality.

A field test using coal:DRDF blends in spreader stoker-fired boilers. Final report, June 1976-July 1978  

SciTech Connect (OSTI)

This program was conducted to characterize and demonstrate the technical, economic, and environmental feasibility of combustion densified forms of refuse derived fuel (dRDF) blended with coal in spreader stoker-fired boilers. A total of 258.5 Mg (285 tons) of pelletized 1/2-inch-diameter x 3/4-inch-long dRDF was co-fired with coal in 2.7 x 7.5 kg/sec (60,000 lb/hr) and 3.6 x 10 kg/sec (75,000 lb/hr) of 1.03 MPa (150 psig) saturated steam. The results indicate that coal:dRDF blends up to 1:2 can be handled and burned in conventional spreader stoker-fired boilers without major equipment modification. As more dRDF was substituted for coal, the flame volume increased, the opacity decreased, the fly ash carbon burnout improved, and the turndown ratio of boiler operation increased. The emissions from the blend firing decreased slightly in mass flux, dropped significantly in particulate size and stack opacity, and had satisfactory particulate resistivities.

An experimental study of gaseous exhaust emissions of diesel engine using blend of natural fatty acid methyl ester  

Science Journals Connector (OSTI)

Vegetable oil form in Natural Fatty Acid Methyl Ester (FAME) has their own advantages: first of all they are available everywhere in the world. Secondly, they are renewable as the vegetables which produce oil seeds can be planted year after year. Thirdly, they are friendly with our environment, as they seldom contain sulphur element in them. This makes vegetable fuel studies become current among the various popular investigations. This study is attempt to optimization of using blend FAME on diesel engine by experimental laboratory. The investigation experimental project is comparison between using blend FAME and base diesel fuel. The engine experiment is conducted with YANMAR TF120M single cylinder four stroke diesel engine set-up at variable engine speed with constant load. The data have been taken at each point of engine speed during the stabilized engine-operating regime. Measurement of emissions parameters at difference engine speed conditions have generally indicated lower in emission NOx, but slightly higher on CO2 emission. The result also shown that the blends FAME are good in fuel consumption and potentially good substitute fuels for diesel engine

THE EFFECTS OF BIODIESEL BLENDS AND ARCO EC-DIESEL ON EMISSIONS from LIGHT HEAVY-DUTY DIESEL VEHICLES  

SciTech Connect (OSTI)

Chassis dynamometer tests were performed on 7 light heavy-duty diesel trucks comparing the emissions of a California diesel fuel with emissions from 4 other fuels: ARCO EC-diesel (EC-D) and three 20% biodiesel blends (1 yellow grease and 2 soy-based). The EC-D and the yellow grease biodiesel blend both showed significant reductions in THC and CO emissions over the test vehicle fleet. EC-D also showed reductions in PM emission rates. NOx emissions were comparable for the different fuel types over the range of vehicles tested. The soy-based biodiesel blends did not show significant or consistent emissions differences over all test vehicles. Total carbon accounted for more than 70% of the PM mass for 4 of the 5 sampled vehicles. Elemental and organic carbon ratios varied significantly from vehicle-to-vehicle but showed very little fuel dependence. Inorganic species represented a smaller portion of the composite total, ranging from 0.2 to 3.3% of the total PM. Total PAH emissions ranged from approximately 1.8 mg/mi to 67.8 mg/mi over the different vehicle/fuel combinations representing between 1.6 and 3.8% of the total PM mass.

It can be seen that the laminar-burning velocity of hydrogen is 5 times that of natural gas and that the quenching distance of hydrogen is one-third that of natural gas, while the latter is beneficial to reduce the unburned hydrocarbons near the wall and from the top-land crevice. ... The signal of cylinder pressure was acquired for every 0.5 deg CA, the acquisition process covered 254 completed cycles, and the averaged value of these 254 cycles was outputted as the pressure data for calculation of the combustion parameters. ... Two factors are considered to influence the cylinder pressure:? one is the increase in flame propagation speed or combustion speed with the increase of the hydrogen fraction in the blends, and this will cause a rapid rising in the cylinder pressure and bring a higher value of the peak cylinder pressure; another is the decrease in the heating value of the fuel blends with the increase of the hydrogen fraction in natural gas?hydrogen blends, and this will decrease the volumetric heat release rate and the cylinder pressure rising, leading to the lower value of the peak cylinder pressure. ...

Molecular Components of Catalytic Selectivity  

SciTech Connect (OSTI)

Selectivity, that is, to produce one molecule out of many other thermodynamically feasible product molecules, is the key concept to develop 'clean manufacturing' processes that do not produce byproducts (green chemistry). Small differences in potential energy barriers for elementary reaction steps control which reaction channel is more likely to yield the desired product molecule (selectivity), instead of the overall activation energy for the reaction that controls turnover rates (activity). Recent studies have demonstrated the atomic- or molecular-level tailoring of parameters such as the surface structures of active sites that give rise to nanoparticle size and shape dependence of turnover rates and reaction selectivities. Here, we highlight seven molecular components that influence reaction selectivities. These include: surface structure, adsorbate-induced restructuring, adsorbate mobility, reaction intermediates, surface composition, charge transport, and oxidation states for model metal single crystal and colloid nanoparticle catalysts. We show examples of their functioning and describe in-situ instruments that permit us to investigate their roles in surface reactions.

Norsk Hydro's communication to international capital markets: A blend of accounting principles  

Science Journals Connector (OSTI)

Companies operating internationally are faced with the dilemma of how to attract investors from multiple exchanges to provide capital. While each investor may prefer a report tailored to his or her country's generally accepted accounting and auditing framework, such an approach can be prohibitively expensive. The selection of International Accounting Standards Committee (IASC) guidance for reporting suffers from its lack of acceptance to date by the International Organization of Securities Commissions (IOSCO). The choice of the United States Generally Accepted Accounting Principles (U.S.GAAP) and Generally Accepted Auditing Standards (U.S. GAAS) facilitate access to large capital markers on the New York Stock Exchange, AMEX or NASDAQ but may not communicate effectively to the European or other markets. Norsk Hydro, the subject of this paper, chose to blend its domestic and U.S. accounting principles, with some episodic integration of European audit report language. The potential communication and regulatory challenges that resulted are described, as are the plethora of topics for future research, given such experimentation in financial reporting.

Eight-band k?p model of strained zinc-blende crystals  

Science Journals Connector (OSTI)

Second-order Löwdin perturbation theory is used to calculate the interaction matrices for an eight-band k?p model (near the ? point) of zinc-blende crystals under a uniform strain. The model treats the ?6 conduction bands, ?8 valence bands, and ?7 spin-orbit split-off bands. The model includes strain interactions arising from both the orbital and spin-orbit terms of the Hamiltonian. In addition to the usual Pikus-Bir deformation-potential constants, a, b, and d, which describe the coupling of the valence band to strain, two new deformation-potential constants arise, a’ and b’, which describe the coupling of the conduction band to strain. The constant a’ couples the conduction band to hydrostatic deformations and the constant b’, which results from a lack of inversion symmetry, couples the conduction band to shear deformations. The strain also introduces a k-dependent conduction-band–valence-band mixing that is linear in strain, in wave vector, and in the momentum matrix element between the conduction and valence bands. In the absence of strain, the eight-band Kane model is recovered. Under a finite strain, in the limit of a large conduction-band–valence-band gap and large spin-orbit splitting, the four-band Luttinger model with strain is recovered.

Effects of Propane/Natural Gas Blended Fuels on Gas Turbine Pollutant Emissions  

SciTech Connect (OSTI)

U.S. natural gas composition is expected to be more variable in the future. Liquefied natural gas (LNG) imports to the U.S. are expected to grow significantly over the next 10-15 years. Unconventional gas supplies, like coal-bed methane, are also expected to grow. As a result of these anticipated changes, the composition of fuel sources may vary significantly from existing domestic natural gas supplies. To allow the greatest use of gas supplies, end-use equipment should be able to accommodate the widest possible gas composition. For this reason, the effect of gas composition on combustion behavior is of interest. This paper will examine the effects of fuel variability on pollutant emissions for premixed gas turbine conditions. The experimental data presented in this paper have been collected from a pressurized single injector combustion test rig at the National Energy Technology Laboratory (NETL). The tests are conducted at 7.5 atm with a 589K air preheat. A propane blending facility is used to vary the Wobbe Index of the site natural gas. The results indicate that propane addition of about five (vol.) percent does not lead to a significant change in the observed NOx emissions. These results vary from data reported in the literature for some engine applications and potential reasons for these differences are discussed.

Study of polymers and their blends using TOF-SIMS ion imaging  

Science Journals Connector (OSTI)

Abstract Time of flight mass spectrometry (TOF-SIMS) was used to see the feasibility of viewing polymer directionality initially of simple polymers like polyethylene (PE) and then graduating to relatively more complex polymer composites involving poly-urethene (PU) and Carbon Nano Tube (CNT) admixture with different mixture concentrations using the Bi ion source. Based on the ion images obtained, it is suggested that directional characteristics of polyethylene, or polyurethane were not visible. However, CNT clusters were identifiable in the pure form of the material and so was CNT inside the admixture. Change in cluster shape inside the admixture at different concentrations indicated the extent of change in strength in the polymer mixture to expect. It was possible to correlate such information with the polymer tensile strength and hardness data measured separately by traditional methods. Similar analysis of high resolution TOF-SIMS ion imaging of other polymer blends are likely to fetch important information on why certain compositions are stronger or why certain compositions do not have the desired or expected properties.

Compact reaction cell for homogenizing and down-blending highly enriched uranium metal  

DOE Patents [OSTI]

The invention is a specialized reaction cell for converting uranium metal to uranium oxide. In a preferred form, the reaction cell comprises a reaction chamber with increasing diameter along its length (e.g. a cylindrical chamber having a diameter of about 2 inches in a lower portion and having a diameter of from about 4 to about 12 inches in an upper portion). Such dimensions are important to achieve the necessary conversion while at the same time affording criticality control and transportability of the cell and product. The reaction chamber further comprises an upper port and a lower port, the lower port allowing for the entry of reactant gases into the reaction chamber, the upper port allowing for the exit of gases from the reaction chamber. A diffuser plate is attached to the lower port of the reaction chamber and serves to shape the flow of gas into the reaction chamber. The reaction cell further comprises means for introducing gases into the reaction chamber and a heating means capable of heating the contents of the reaction chamber. The present invention also relates to a method for converting uranium metal to uranium oxide in the reaction cell of the present invention. The invention is useful for down-blending highly enriched uranium metal by the simultaneous conversion of highly enriched uranium metal and natural or depleted uranium metal to uranium oxide within the reaction cell. 4 figs.

Expandable Metal Liner For Downhole Components  

DOE Patents [OSTI]

A liner for an annular downhole component is comprised of an expandable metal tube having indentations along its surface. The indentations are formed in the wall of the tube either by drawing the tube through a die, by hydroforming, by stamping, or roll forming and may extend axially, radially, or spirally along its wall. The indentations accommodate radial and axial expansion of the tube within the downhole component. The tube is inserted into the annular component and deformed to match an inside surface of the component. The tube may be expanded using a hydroforming process or by drawing a mandrel through the tube. The tube may be expanded in such a manner so as to place it in compression against the inside wall of the component. The tube is useful for improving component hydraulics, shielding components from contamination, inhibiting corrosion, and preventing wear to the downhole component during use. It may also be useful for positioning conduit and insulated conductors within the component. An insulating material may be disposed between the tube and the component in order to prevent galvanic corrosion of the downhole component.

Reducing hazardous waste incinerator emissions through blending: A study of 1,1,1-trichloroethane injection  

SciTech Connect (OSTI)

We investigate whether blending liquid hazardous wastes with hydrocarbons such as alkanes can improve the destruction efficiency and reduce the combustion byproduct levels in the post-flame region of a laboratory scale combustor. Outlet species concentrations are measured with an FTIR spectrometer for mixtures of 1,1,1-trichloroethane and 25% (by volume) dodecane or heptane injected as a spray of droplets. We also inject sprays of liquid pure 1,1,1-trichloroethane, gaseous pure 1,1,1-trichloroethane, and gaseous 1,1,1-trichloroethane with 25% (by volume) heptane. Once vaporized, the 1,1,1-trichloroethane decomposes to form CO{sub 2} and HCl through the intermediates 1,1-dichloroethylene, phosgene, acetylene, and carbon monoxide. The 1,1,1-trichloroethane/alkane mixtures also form the intermediate ethylene. No significant differences are observed between injecting the compounds as a droplet spray or as a gaseous jet, not as unexpected result as the mixing time of the gas jet is longer than the vaporization time of the droplets. The addition of heptane or dodecane to 1,1,1-trichloroethane produces two principal effects: an increase in ethylene, acetylene and carbon monoxide levels for injection temperatures between 950 to 1040 K, and a decrease in 1,1-dichloroethylene, phosgene, acetylene, and carbon monoxide levels for injection temperatures greater than 1050 K. Reaction of the injected alkane causes the former effect, while the additional heat of combustion of the alkane additives causes the latter. 17 refs., 6 figs., 3 tabs.

Emission Characteristics of a Diesel Engine Operating with In-Cylinder Gasoline and Diesel Fuel Blending  

SciTech Connect (OSTI)

Advanced combustion regimes such as homogeneous charge compression ignition (HCCI) and premixed charge compression ignition (PCCI) offer benefits of reduced nitrogen oxides (NOx) and particulate matter (PM) emissions. However, these combustion strategies often generate higher carbon monoxide (CO) and hydrocarbon (HC) emissions. In addition, aldehydes and ketone emissions can increase in these modes. In this study, the engine-out emissions of a compression-ignition engine operating in a fuel reactivity- controlled PCCI combustion mode using in-cylinder blending of gasoline and diesel fuel have been characterized. The work was performed on a 1.9-liter, 4-cylinder diesel engine outfitted with a port fuel injection system to deliver gasoline to the engine. The engine was operated at 2300 rpm and 4.2 bar brake mean effective pressure (BMEP) with the ratio of gasoline to diesel fuel that gave the highest engine efficiency and lowest emissions. Engine-out emissions for aldehydes, ketones and PM were compared with emissions from conventional diesel combustion. Sampling and analysis was carried out following micro-tunnel dilution of the exhaust. Particle geometric mean diameter, number-size distribution, and total number concentration were measured by a scanning mobility particle sizer (SMPS). For the particle mass measurements, samples were collected on Teflon-coated quartz-fiber filters and analyzed gravimetrically. Gaseous aldehydes and ketones were sampled using dinitrophenylhydrazine-coated solid phase extraction cartridges and the extracts were analyzed by liquid chromatography/mass spectrometry (LC/MS). In addition, emissions after a diesel oxidation catalyst (DOC) were also measured to investigate the destruction of CO, HC and formaldehydes by the catalyst.

VALIDATION OF FIRESIDE PERFORMANCE INDICES: FOULING/CORROSION EVALUATION OF MDF PARTICLEBOARD AND BLENDS WITH WHEAT STRAW BOARD  

SciTech Connect (OSTI)

Sauder Woodworking currently fires a large portion of all wood wastes in a boiler producing process steam. It is investigating using particleboard made from wheat straw in its manufacturing process and is concerned with the effects of the inorganics on its boiler. Wheat straw board contains higher ash contents and increased levels of potassium, creating concern over fouling characteristics in Sauder's tight boiler design. In addition, the wheat straw board contains high concentrations of chlorine, which may affect boiler tube corrosion when fired in combination with the particleboard wastes currently generated. Sauder has engaged the services of the Energy & Environmental Research Center (EERC) at the University of North Dakota to investigate the potential detrimental effects of firing blends containing wheat straw on boiler tube fouling and corrosion. Additional funding for this project was provided through the U.S. Department of Energy Jointly Sponsored Research Program (DOE JSRP) project ''Validation of Fireside Performance Indices'' to validate, improve, and expand the PCQUEST (Predictive Coal Quality Effects Screening Tool) program. The PCQUEST fuel database is constantly expanding and adding new fuels, for which the algorithms may need refinement and additional verification in order to accurately predict index values. A key focus is on performing advanced and conventional fuel analyses and adding these analyses to the PCQUEST database. Such fuels include coals of all ranks and origins, upgraded coals, petroleum coke, biomass and biomass-coal blends, and waste materials blended with coal. Since there are differences in the chemical and mineral form of the inorganic content in biomass and substantial differences in organic matrix characteristics, analysis and characterization methods developed for coal fuels may not be applicable. The project was seen to provide an excellent opportunity to test and improve the ability of PCQUEST to handle nontypical soil and biomass minerals.

In this brief communication, we present new experimental species profile measurements for the low and intermediate temperature oxidation of ethanol under knock-prone conditions. These experiments show that ethanol exhibits no global low temperature reactivity at these conditions, although we note the heterogeneous decomposition of ethanol to ethylene and water. Similar behavior is reported for an E85 blend in n-heptane. Kinetic modeling results are presented to complement these experiments and elucidate the interaction of ethanol and primary reference fuels undergoing cooxidation. (author)

Experimental study on combustion characteristics of a spark-ignition engine fueled with natural gas–hydrogen blends combining with EGR  

Science Journals Connector (OSTI)

An experimental study on the effect of hydrogen fraction and EGR rate on the combustion characteristics of a spark-ignition engine fueled with natural gas–hydrogen blends was investigated. The results show that flame development duration, rapid combustion duration and total combustion duration are increased with the increase of EGR rate and decreased with the increase of hydrogen fraction in the blends. Hydrogen addition shows larger influence on flame development duration than that on rapid combustion duration. The coefficient of variation of the indicated mean effective pressure increases with the increase of EGR rate. And hydrogen addition into natural gas decreases the coefficient of variation of the indicated mean effective pressure, and this effectiveness becomes more obviously at high EGR rate. Engine fueled with natural gas–hydrogen blends combining with proper EGR rate can realize the stable low temperature combustion in gas engine.

Correct Execution of Reconfiguration for Stateful Components  

Science Journals Connector (OSTI)

In component-based software engineering, reconfiguration describes structural changes to the architecture of a component system. For stateful components, not only structural but also behavioural aspects have to be taken into account in reconfiguration. We present a procedure to conduct reconfiguration in systems of concurrent, stateful components that interferes as little as possible with unchanged subsystems. Reconfiguration is described by a plan for adding, deleting and reconnecting components. A plan is executed by a sequence of simple, local steps, which are suitable for implementation in a programming language. We prove that plan execution is indistinguishable from atomic reconfiguration and use this fact for state-space reduction for verifying properties by model checking.

In collaboration with participants of the Coordinating Research Council (CRC) Advanced Vehicle/Fuels/Lubricants (AVFL) Committee, and project AVFL-19, the characteristics of fuels from advanced and renewable sources were compared to commercial diesel fuels. The main objective of this study was to highlight similarities and differences among the fuel types, i.e. ULSD, renewables, and alternative fuels, and among fuels within the different fuel types. This report summarizes the carbon-type analysis from 1H and 13C{1H} nuclear magnetic resonance spectroscopy (NMR) of 14 diesel fuel samples. The diesel fuel samples come from diverse sources and include four commercial ultra-low sulfur diesel fuels (ULSD), one gas-to-liquid diesel fuel (GTL), six renewable diesel fuels (RD), two shale oil-derived diesel fuels, and one oil sands-derived diesel fuel. Overall, the fuels examined fall into two groups. The two shale oil-derived samples and the oil-sand-derived sample closely resemble the four commercial ultra-low sulfur diesels, with SO1 and SO2 most closely matched with ULSD1, ULSD2, and ULSD4, and OS1 most closely matched with ULSD3. As might be expected, the renewable diesel fuels, with the exception of RD3, do not resemble the ULSD fuels because of their very low aromatic content, but more closely resemble the gas-to-liquid sample (GTL) in this respect. RD3 is significantly different from the other renewable diesel fuels in that the aromatic content more closely resembles the ULSD fuels. Fused-ring aromatics are readily observable in the ULSD, SO, and OS samples, as well as RD3, and are noticeably absent in the remaining RD and GTL fuels. Finally, ULSD3 differs from the other ULSD fuels by having a significantly lower aromatic carbon content and higher cycloparaffinic carbon content. In addition to providing important comparative compositional information regarding the various diesel fuels, this report also provides important information about the capabilities of NMR spectroscopy for the detailed characterization and comparison of fuels and fuel blends.

Determination of the effect of different additives in coking blends using a combination of in situ high-temperature {sup 1}H NMR and rheometry  

SciTech Connect (OSTI)

High-temperature {sup 1}H NMR and rheometry measurements were carried out on 4:1 wt/wt blends of a medium volatile bituminous coal with two anthracites, two petroleum cokes, charcoal, wood, a low-temperature coke breeze, tyre crumb, and active carbon to determine the effects on fluidity development to identify the parameters responsible for these effects during pyrolysis and to study possible relationships among the parameters derived from these techniques. Positive, negative, and neutral effects were identified on the concentration of fluid material. Small positive effects (ca. 5-6%) were caused by blending the coal with petroleum cokes. Charcoal, wood, and active carbon all exerted negative effects on concentration (18-27% reduction) and mobility (12-25% reduction in T2) of the fluid phase, which have been associated with the inert character and high surface areas of these additives that adsorb the fluid phase of the coal. One of the anthracites and the low-temperature coke breeze caused deleterious effects to a lesser extent on the concentration (7-12%) and mobility (13-17%) of the fluid material, possibly due to the high concentration of metals in these additives (ca. 11% ash). Despite the high fluid character of tyre crumb at the temperature of maximum fluidity of the coal (73%), the mobility of the fluid phase of the blend was lower than expected. The comparison of {sup 1}H NMR and rheometry results indicated that to account for the variations in minimum complex viscosity for all the blends, both the maximum concentration of fluid phase and the maximum mobility of the fluid material had to be considered. For individual blends, two exponential relationships have been found between the complex viscosity and the concentration of solid phase in both the softening and resolidification stages but the parameters are different for each blend. 30 refs., 8 figs., 5 tabs.

Evaluating the use of EN 14078 for determination of biodiesel in diesel blends sold in the Brazilian market  

Science Journals Connector (OSTI)

Abstract In Brazil, the National Agency of Petroleum, Natural Gas and Biofuels (ANP) is a regulatory agency responsible for monitoring the distribution and sale of fuels. After the introduction of biodiesel in Brazil, problems began to emerge as well as questions regarding the quality of diesel fuel in the country. One of the problems is related to the determination of biodiesel content in the diesel available in fuel stations. This work shows that biodiesel prepared from different feedstock during storage suffers oxidative degradation leading to different oxygenated compounds. The presence of these biodiesel oxidation products affects the accuracy of the result provided by the standard method EN 14078 in relation to the content of biodiesel in diesel. The result showed determination errors of almost 100%. Indeed, a B5 blend after accelerated oxidation was determined using EN 14078 as B10. Another problem observed using EN 14078 was that in countries like Brazil, where different oleaginous or alcohol are used to produce biodiesel, it is mandatory to calibrate the method with the same biodiesel present in diesel blends. Indeed, it was observed important changes in the position of the stretching related to the ester carboxyl group according to the raw materials used to prepare the biofuel, leading to significant errors in the biodiesel content determination.

Effects of oxygenated fuel blends on carbonaceous particulate composition and particle size distributions from a stationary diesel engine  

Science Journals Connector (OSTI)

Abstract A systematic study was conducted to evaluate and compare the effects of blending five different oxygenated compounds, diglyme (DGM), palm oil methyl ester (PME), dimethyl carbonate (DMC), diethyl adipate (DEA) and butanol (Bu) with ultralow sulfur diesel (ULSD), on engine performance, particulate mass concentrations, organic (OC) and elemental (EC) carbon fractions of the particles and particle size distributions from a single cylinder, direct injection stationary diesel engine with the engine working at a constant engine speed and at three engine loads. A small increase in the brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) was observed with the use of oxygenates blended with ULSD. All five oxygenates were found to be effective at reducing particulate mass emissions at medium and high engine loads, with butanol being the most effective and DGM being the least effective. Analysis of the relative contribution of changes in the OC and EC emissions to the reduction of particulate matter indicated that under the same oxygen content, EC made a dominant contribution to the reduction of particulate mass. The results also indicated that reduction in both particle mass and number emissions was affected not only by the oxygen content, but also by the chemical structure and thermophysical properties of oxygenates as well as engine operating conditions.

Performance Engineering Technology for Scientific Component Software  

SciTech Connect (OSTI)

Large-scale, complex scientific applications are beginning to benefit from the use of component software design methodology and technology for software development. Integral to the success of component-based applications is the ability to achieve high-performing code solutions through the use of performance engineering tools for both intra-component and inter-component analysis and optimization. Our work on this project aimed to develop performance engineering technology for scientific component software in association with the DOE CCTTSS SciDAC project (active during the contract period) and the broader Common Component Architecture (CCA) community. Our specific implementation objectives were to extend the TAU performance system and Program Database Toolkit (PDT) to support performance instrumentation, measurement, and analysis of CCA components and frameworks, and to develop performance measurement and monitoring infrastructure that could be integrated in CCA applications. These objectives have been met in the completion of all project milestones and in the transfer of the technology into the continuing CCA activities as part of the DOE TASCS SciDAC2 effort. In addition to these achievements, over the past three years, we have been an active member of the CCA Forum, attending all meetings and serving in several working groups, such as the CCA Toolkit working group, the CQoS working group, and the Tutorial working group. We have contributed significantly to CCA tutorials since SC'04, hosted two CCA meetings, participated in the annual ACTS workshops, and were co-authors on the recent CCA journal paper [24]. There are four main areas where our project has delivered results: component performance instrumentation and measurement, component performance modeling and optimization, performance database and data mining, and online performance monitoring. This final report outlines the achievements in these areas for the entire project period. The submitted progress reports for the first two years describe those year's achievements in detail. We discuss progress in the last project period in this document. Deployment of our work in CCA components, frameworks, and applications is an important metric of success. We also summarize the project's accomplishments in this regard at the end of the report. A list of project publications is also given.

Investigation of the Effects of Biodiesel-based Na on Emissions Control Components  

SciTech Connect (OSTI)

A single-cylinder diesel engine was used to investigate the impact of biodiesel-based Na on emissions control components using specially blended 20% biodiesel fuel (B20). The emissions control components investigated were a diesel oxidation catalyst (DOC), a Cu-zeolite-based NH{sub 3}-SCR (selective catalytic reduction) catalyst, and a diesel particulate filter (DPF). Both light-duty vehicle, DOC-SCR-DPF, and heavy-duty vehicle, DOC-DPF-SCR, emissions control configurations were employed. The accelerated Na aging is achieved by introducing elevated Na levels in the fuel, to represent full useful life exposure, and periodically increasing the exhaust temperature to replicate DPF regeneration. To assess the validity of the implemented accelerated Na aging protocol, engine-aged lean NO{sub x} traps (LNTs), DOCs and DPFs are also evaluated. To fully characterize the impact on the catalytic activity the LNT, DOC and SCR catalysts were evaluated using a bench flow reactor. The evaluation of the aged DOC samples and LNT show little to no deactivation as a result of Na contamination. However, the SCR in the light-duty configuration (DOC-SCR-DPF) was severely affected by Na contamination, especially when NO was the only fed NO{sub x} source. In the heavy-duty configuration (DOC-DPF-SCR), no impact is observed in the SCR NO{sub x} reduction activity. Electron probe micro-analysis (EPMA) reveals that Na contamination on the LNT, DOC, and SCR samples is present throughout the length of the catalysts with a higher concentration on the washcoat surface. In both the long-term engine-aged DPF and the accelerated Na-aged DPFs, there is significant Na ash present in the upstream channels; however, in the engine-aged sample lube oil-based ash is the predominant constituent.

Engine combustion, performance and emission characteristics of gas to liquid (GTL) fuels and its blends with diesel and bio-diesel  

Science Journals Connector (OSTI)

Abstract Crude oil price hikes, energy security concerns and environmental drivers have turned the focus to alternative fuels. Gas to liquid (GTL) diesel is regarded as a promising alternative diesel fuel, considering the adeptness to use directly as a diesel fuel or in blends with petroleum-derived diesel or bio-diesel. GTL fuel derived from Fischer–Tropsch synthesis is of distinctly different characteristics than fossil diesel fuel due to its paraffinic nature, virtually zero sulfur, low aromatic contents and very high cetane number. GTL fuel is referred to as a “clean fuel” for its inherent ability to reduce engine exhaust emission even with blends of diesel and bio-diesel. This paper illustrates feasibility of GTL fuel in context of comparative fuel properties with conventional diesel and bio-diesels. This review also describes the technical attributes of GTL and its blends with diesel and bio-diesel focusing their impact on engine performance and emission characteristics on the basis of the previous research works. It can introduce an efficacious guideline to devise several blends of alternative fuels, further the development of engine performance and constrain exhaust emission to cope with the relentless efforts to manufacture efficient and environment friendly powertrains.

U.S. Department of Energy FreedomCAR & Vehicle Technologies Program Advanced Vehicle Testing Activity, Hydrogen/CNG Blended Fuels Performance Testing in a Ford F-150  

SciTech Connect (OSTI)

Federal regulation requires energy companies and government entities to utilize alternative fuels in their vehicle fleets. To meet this need, several automobile manufacturers are producing compressed natural gas (CNG)-fueled vehicles. In addition, several converters are modifying gasoline-fueled vehicles to operate on both gasoline and CNG (Bifuel). Because of the availability of CNG vehicles, many energy company and government fleets have adopted CNG as their principle alternative fuel for transportation. Meanwhile, recent research has shown that blending hydrogen with CNG (HCNG) can reduce emissions from CNG vehicles. However, blending hydrogen with CNG (and performing no other vehicle modifications) reduces engine power output, due to the lower volumetric energy density of hydrogen in relation to CNG. Arizona Public Service (APS) and the U.S. Department of Energy’s Advanced Vehicle Testing Activity (DOE AVTA) identified the need to determine the magnitude of these effects and their impact on the viability of using HCNG in existing CNG vehicles. To quantify the effects of using various blended fuels, a work plan was designed to test the acceleration, range, and exhaust emissions of a Ford F-150 pickup truck operating on 100% CNG and blends of 15 and 30% HCNG. This report presents the results of this testing conducted during May and June 2003 by Electric Transportation Applications (Task 4.10, DOE AVTA Cooperative Agreement DEFC36- 00ID-13859).

Artificial neural networks based prediction of performance and exhaust emissions in direct injection engine using castor oil biodiesel-diesel blends  

Science Journals Connector (OSTI)

In this study the performance and emission characteristics of a direct injection diesel engine using castor oil biodiesel (COB)-diesel blended fuels were investigated experimentally and then predicted by artificial neural networks. For this aim castor oil was converted to its biodiesel via transesterification approach. Then the effects of the biodiesel percentage in blend engine load and speed on brake power brake specific fuel consumption (BSFC) nitrogen oxides (NOx) carbon dioxide (CO2) carbon monoxide (CO) and particle matter (PM) have been considered. Fuel blends with various percentages of biodiesel (0% 5% 10% 15% 20% 25% and 30%) at various engine speeds and loads were tested. The results indicated that blends of COB with diesel fuel provide admissible engine performance; on the other side emissions decreased so much. Two types of neural networks a group method of data handling (GMDH) and feed forward were used for modeling of the diesel engine to predict brake power BSFC and exhaust emissions such as CO CO2 NOx and PM values. The comparison results demonstrate the superiority of the feed forward neural networkmodels over GMDH type models in terms of the statistical measures in the training and testing data but in the number of hidden neurons and model simplicity GMDH models are preferred.

Engine performance and emissions from the combustion of low-temperature Fischerâ??Tropsch synthetic diesel fuel and biodiesel rapeseed methyl ester blends  

Science Journals Connector (OSTI)

The combustion of oxygenated biodiesel (rapeseed methyl ester (RME)) improves the engine-out particulate matter, hydrocarbon and carbon monoxide (CO) emissions, while the low-temperature Fischerâ??Tropsch synthetic paraffinic diesel fuel improves engine-out NOx, CO, hydrocarbon and particulate matter emissions. Blending synthetic diesel (SD) fuel with oxygenated biodiesel could unlock potential performance synergies in the fuel properties (e.g. O2 content in RME and high cetane number of the synthetic fuels) of such blends and benefit engine performance and emissions. The combustion of synthetic diesel fuel/RME blend, named synthetic diesel B50, has shown similar combustion characteristics to diesel fuel, while simultaneous improvements in engine efficiency and smoke-NOx trade-off were achieved by taking advantage of the fuel's properties. The engine thermal efficiency was dependent on the fuel type, and followed the general trend: synthetic diesel > SDB50 > diesel > RME. Therefore, it has been shown that the design of a synthetic fuel with properties similar to the fuel blends presented in this work could improve engine-out NOx, smoke and hydrocarbon emissions and maintain or improve engine performance.

Effect of Biodiesel Blending on the Speciation of Soluble Organic Fraction from a Light Duty Diesel Engine  

SciTech Connect (OSTI)

Soy methyl ester (SME) biodiesel was volumetrically blended with 2007 certification ultra low sulfur diesel (ULSD) fuel and run in a 1.7L direct-injection common rail diesel engine at one speed-load point (1500rpm, 2.6bar BMEP). Engine fueling rate and injection timing were adjusted to maintain a constant load, while particulate samples were collected in a diesel particulate filter (DPF) and with a dilution tunnel sampling train. The samples collected at these two locations were found to contain different levels of soluble organic fraction (SOF) and the different hydrocarbon species in the SOF. This observation indicates that traditional SOF measurements, in light of the specific sampling procedure used, may not be appropriate to DPF applications.

In 1993, the United States alone generated approximately 207 million ton per year of Municipal Solid Waste (MSW), with 62% landfilled, 220/6 recycled, and 16% combusted for energy recovery. Despite strenuous efforts to make these disposal methods meet present needs, the cost of disposal is rising dramatically. Concurrently, the Clean Air Act Amendments (CAAA) of 1990 have severely restricted the SO{sub 2} emissions from coal fired boilers. Medium and high sulfur coals will not comply with the Phase II CAAA regulation limit of 1.2 lb SO{sub 2}/MM Btu, without advanced coal cleaning technologies or flue gas desulfurization, including the majority of the North Dakota lignite reserves. Utility power plants have attempted to burn refuse derived fuel (RDF), a heterogeneous solid fuel produced from MSW, with coal in utility scale boilers (generally referred to as co-firing). Co-firing of RDF with coal has been attempted in sixteen different boilers, five commercially. While lower SO{sub 2} emissions provided the impetus, co-firing RDF with coal suffered from several disadvantages including increased solids handling, increased excess air requirements, higher HCI, CO, NO{sub x} and chlorinated organic emissions, increased slag formation in the boiler, and higher fly ash resistivity. Currently, only two of the sixteen boilers are still regularly used to co-fire RDF. The overall objective of this research program was to assess the feasibility of blending RDF with lignite coal to form SO{sub 2} Compliant slurry fuels using EnerTech`s SlurryCarb{trademark} process. In particular, the objective was to overcome the difficulties of conventional co-firing. Blended slurry fuels were produced with the Energy & Environmental Research Center`s (EERC) bench-scale autoclave and were combusted in a pressurized fluidized-bed reactor (PFBR).

Component external leakage and rupture frequency estimates  

SciTech Connect (OSTI)

In order to perform detailed internal flooding risk analyses of nuclear power plants, external leakage and rupture frequencies are needed for various types of components - piping, valves, pumps, flanges, and others. However, there appears to be no up-to-date, comprehensive source for such frequency estimates. This report attempts to fill that void. Based on a comprehensive search of Licensee Event Reports (LERs) contained in Nuclear Power Experience (NPE), and estimates of component populations and exposure times, component external leakage and rupture frequencies were generated. The remainder of this report covers the specifies of the NPE search for external leakage and rupture events, analysis of the data, a comparison with frequency estimates from other sources, and a discussion of the results.

Five-quark components in baryons  

E-Print Network [OSTI]

Evidence has been accumulating for the existence of significant intrinsic non-perturbative five-quark components in various baryons. The inclusion of the five-quark components gives a natural explanation of the excess of $\\bar d$ over $\\bar u$, significant quark orbital angular momentum in the proton, the problematic mass and decay pattern of the lowest $1/2^-$ baryon nonet, etc.. A breathing mode of $qqq\\leftrightarrow qqqq\\bar q$ is suggested for the lowest $1/2^-$ baryon octet. Evidence of a predicted member of the new scheme, $\\Sigma^*(1/2^-)$ around 1380 MeV, is introduced.

Technique for Measuring Hybrid Electronic Component Reliability  

SciTech Connect (OSTI)

Materials compatibility studies of aged, engineered materials and hardware are critical to understanding and predicting component reliability, particularly for systems with extended stockpile life requirements. Nondestructive testing capabilities for component reliability would significantly enhance lifetime predictions. For example, if the detection of crack propagation through a solder joint can be demonstrated, this technique could be used to develop baseline information to statistically determine solder joint lifelengths. This report will investigate high frequency signal response techniques for nondestructively evaluating the electrical behavior of thick film hybrid transmission lines.

A robust transmission element for transmitting information between downhole tools, such as sections of drill pipe, in the presence of hostile environmental conditions, such as heat, dirt, rocks, mud, fluids, lubricants, and the like. The transmission element maintains reliable connectivity between transmission elements, thereby providing an uninterrupted flow of information between drill string components. A transmission element is mounted within a recess proximate a mating surface of a downhole drilling component, such as a section of drill pipe. To close gaps present between transmission elements, transmission elements may be biased with a "spring force," urging them closer together.

Enabling Technologies for Ceramic Hot Section Components  

SciTech Connect (OSTI)

Silicon-based ceramics are attractive materials for use in gas turbine engine hot sections due to their high temperature mechanical and physical properties as well as lower density than metals. The advantages of utilizing ceramic hot section components include weight reduction, and improved efficiency as well as enhanced power output and lower emissions as a result of reducing or eliminating cooling. Potential gas turbine ceramic components for industrial, commercial and/or military high temperature turbine applications include combustor liners, vanes, rotors, and shrouds. These components require materials that can withstand high temperatures and pressures for long duration under steam-rich environments. For Navy applications, ceramic hot section components have the potential to increase the operation range. The amount of weight reduced by utilizing a lighter gas turbine can be used to increase fuel storage capacity while a more efficient gas turbine consumes less fuel. Both improvements enable a longer operation range for Navy ships and aircraft. Ceramic hot section components will also be beneficial to the Navy's Growth Joint Strike Fighter (JSF) and VAATE (Versatile Affordable Advanced Turbine Engines) initiatives in terms of reduced weight, cooling air savings, and capability/cost index (CCI). For DOE applications, ceramic hot section components provide an avenue to achieve low emissions while improving efficiency. Combustors made of ceramic material can withstand higher wall temperatures and require less cooling air. Ability of the ceramics to withstand high temperatures enables novel combustor designs that have reduced NO{sub x}, smoke and CO levels. In the turbine section, ceramic vanes and blades do not require sophisticated cooling schemes currently used for metal components. The saved cooling air could be used to further improve efficiency and power output. The objectives of this contract were to develop technologies critical for ceramic hot section components for gas turbine engines. Significant technical progress has been made towards maturation of the EBC and CMC technologies for incorporation into gas turbine engine hot-section. Promising EBC candidates for longer life and/or higher temperature applications relative to current state of the art BSAS-based EBCs have been identified. These next generation coating systems have been scaled-up from coupons to components and are currently being field tested in Solar Centaur 50S engine. CMC combustor liners were designed, fabricated and tested in a FT8 sector rig to demonstrate the benefits of a high temperature material system. Pretest predictions made through the use of perfectly stirred reactor models showed a 2-3x benefit in CO emissions for CMC versus metallic liners. The sector-rig test validated the pretest predictions with >2x benefit in CO at the same NOx levels at various load conditions. The CMC liners also survived several trip shut downs thereby validating the CMC design methodology. Significant technical progress has been made towards incorporation of ceramic matrix composites (CMC) and environmental barrier coatings (EBC) technologies into gas turbine engine hot-section. The second phase of the program focused on the demonstration of a reverse flow annular CMC combustor. This has included overcoming the challenges of design and fabrication of CMCs into 'complex' shapes; developing processing to apply EBCs to 'engine hardware'; testing of an advanced combustor enabled by CMCs in a PW206 rig; and the validation of performance benefits against a metal baseline. The rig test validated many of the pretest predictions with a 40-50% reduction in pattern factor compared to the baseline and reductions in NOx levels at maximum power conditions. The next steps are to develop an understanding of the life limiting mechanisms in EBC and CMC materials, developing a design system for EBC coated CMCs and durability testing in an engine environment.

Coatings for hot section gas turbine components  

Science Journals Connector (OSTI)

Components in the hot section of gas turbines are protected from the environment by oxidation-resistant coatings while thermal barrier coatings are applied to reduce the metal operating temperature of blades and vanes. The integrity of these protective coatings is an issue of major concern in current gas turbine designs. Premature cracking of the protective layer in oxidation-resistant coatings and of the interface in thermal barrier coating systems has become one of the life limiting factors of coated components in gas turbines. Following a brief overview of the state-of-the-art of coated material systems with respect to coating types and their status of application, the fracture mechanisms and mechanics of coated systems are presented and discussed.
