Acute toxicity of toluene, hexane, xylene, and benzene to the rotifers Brachionus calyciflorus and Brachionus plicatilis  

SciTech Connect

A large number of studies on the biological effects of oil pollution in the aquatic environment deal with the effects of whole crude or refined oils or their water-soluble fractions. However, low boiling, aromatic hydrocarbons, which are probably the most toxic constituents of oil, have until now not been examined in sufficient detail. Toluene, benzene and xylene, constitute a major component of various oils. They may be readily lost by weathering but are toxic in waters that are relatively stagnant and are chronically polluted. Korn et al. have stated that toluene is more toxic than many other hydrocarbons such as benzene, though the latter are more water-soluble. Report of the effects of exposure to organic solvents like hexane or toluene are still limited although organic solvents are a well-known group of neurointoxicants. Various benzene derivates continue to be used as chemical intermediates, solvents, pesticides, so on, in spite of incomplete knowledge of their chronic toxicity. The majority of toxicity studies about the effects of pollution on aquatic organisms under controlled conditions have used either fish or the cladoceran Daphnia magna and there are few studies reported using rotifers. The effects of herbicides on population variables of laboratory rotifer cultures have been investigated. Rotifers are one of the main sources of zooplankton production and they have an important ecological significance in the aquatic environment. The present work was designed to investigate the effect of short-term exposure to some petroleum derivates which might be expected to occur immediately under an oil-slick, on freshwater and brackish environment rotifers. 18 refs., 1 tab.

Reactions of the CN Radical with Benzene and Toluene: Product Detection and Low-Temperature Kinetics  

SciTech Connect

Low temperature rate coefficients are measured for the CN + benzene and CN + toluene reactions using the pulsed Laval nozzle expansion technique coupled with laser-induced fluorescence detection. The CN + benzene reaction rate coefficient at 105, 165 and 295 K is found to be relatively constant over this temperature range, 3.9 - 4.9 x 10-10 cm3 molecule-1 s-1. These rapid kinetics, along with the observed negligible temperature dependence, are consistent with a barrierless reaction entrance channel and reaction efficiencies approaching unity. The CN + toluene reaction is measured to have a slower rate coefficient of 1.3 x 10-10 cm3 molecule-1 s-1 at 105 K. At room temperature, non-exponential decay profiles are observed for this reaction that may suggest significant back-dissociation of intermediate complexes. In separate experiments, the products of these reactions are probed at room temperature using synchrotron VUV photoionization mass spectrometry. For CN + benzene, cyanobenzene (C6H5CN) is the only product recorded with no detectable evidence for a C6H5 + HCN product channel. In the case of CN + toluene, cyanotoluene (NCC6H4CH3) constitutes the only detected product. It is not possible to differentiate among the ortho, meta and para isomers of cyanotoluene because of their similar ionization energies and the ~;; 40 meV photon energy resolution of the experiment. There is no significant detection of benzyl radicals (C6H5CH2) that would suggest a H-abstraction or a HCN elimination channel is prominent at these conditions. As both reactions are measured to be rapid at 105 K, appearing to have barrierless entrance channels, it follows that they will proceed efficiently at the temperatures of Saturn?s moon Titan (~;;100 K) and are also likely to proceed at the temperature of interstellar clouds (10-20 K).

Low cost benzene reduction for RFG  

SciTech Connect

In the typical refinery benzene comes from several sources including: light straight run gasoline, isomerate, reformate, hydrocrackate, FCC gasoline, and coker gasoline. However the benzene from the reformer usually represents 50--80% of the total. As a result the reformate is the natural place to focus benzene reduction. The benzene content of the reformate is normally in the range of 2.5 to 8 volume %. The higher benzene concentrations occur in high pressure reformers due to hydrodealkylation of toluene and heavier alkylbenzenes. Benzene can be reduced in the reformate by removing benzene precursors such as cyclic C{sub 6}`s in the reformer feed. However, hydrodealkylation of other aromatics in the reformer will still leave a reformate benzene content of 1 to 1.5 volume %. More complete control of benzene can be achieved by removing it from the reformate rather than by treating the reformer feed stream. The paper describes the conventional benzene saturation process and the CDHydro process, which combines fractionation with hydrogenation. Capitalized costs are summarized. Refiners can maintain gasoline compositions with high aromatic contents by using the flexibility offered by the Complex Model. CDHydro provides a very cost effective method of benzene control for the refiner. Benzene reduction targets for both 1995 and 2000 are easily met. CDHydro can provide much higher benzene removal than required by the models, thus giving the refiner valuable options for averaging and trading credits.

Mobility of Supercooled liquid Toluene, Ethylbenzene, and Benzene near their Glass Transition Temperatures Investigated using Inert Gas Permeation  

SciTech Connect

We investigate the mobility of supercooled liquid toluene, ethylbenzene, and benzene near their respective glass transition temperatures (Tg). The permeation rate of Ar, Kr, and Xe through the supercooled liquid created when initially amorphous overlayers heated above their glass transition temperature is used to determine the diffusivity. Amorphous benzene crystallizes at temperatures well below its Tg and as a result the inert gas underlayer remains trapped until the onset of benzene desorption. In contrast, for toluene and ethylbenzene the onset of inert gas permeation is observed at temperatues near Tg. The inert gas desorption peak temperature as a function of the heating rate and overlayer thickness is used to quantify the diffusivity of supercooled liquid toluene and ethylbenzene from 115 K to 135 K. In this temperature range, diffusivities are found to vary across five orders of magnitude (~10-14 to 10-9 cm2/s). These data are compared to viscosity measurements and used to determine the low temperature fractional Stokes-Einstein exponent. Efforts to determine the diffusivity of a mixture of benzene and ethylbenzene are detailed, and the effect of mixing these materials on benzene crystallization is explored using infrared spectroscopy.

Effects of dispersion and partial reduction on the catalytic properties of Rh/Al sub 2 O sub 3 catalysts in the steam reforming of mono- and bicyclic aromatics  

SciTech Connect

The steam reforming of toluene, cumene, and methyl-1-naphthalene was studied on well-reduced Rh/Al{sub 2}O{sub 3} catalysts of different dispersions and on partially reduced catalysts in which the dispersion of the metallic phase was maintained at 25 {plus minus} 2%. The principal reactions were dehydrogenation DH (cumene {yields} {alpha}-methylstyrene), dealkylation DA (for instance, toluene {yields} benzene), naphthalene ring opening NRO (methylnaphthalene {yields} benzene + toluene), and degradations DN (total gasification of the molecules). Dispersion and partial reduction effects are shown to occur and can be summarized as follows: a partially reduced sample behaves catalytically as would dispersed and well-reduced catalysts. In this case, DN reactions are much inhibited, whereas DA and, to a lesser extent, NRO are relatively less affected by partial reduction. Moreover, DH is quite unaffected by these factors. The results may be expressed in terms of either electronic (DN favored on particles where the metal is more capable of donating electrons) or geometric effects (DN favored on a large ensemble of adjacent sites). These models are discussed on the basis of kinetic and XPS results, particularly those obtained on partially reduced Rh/Al{sub 2}O{sub 3} catalyst samples. Alloy effects (selectivities modified by the presence of RhAl alloy) could also occur on a catalyst calcined and reduced at high temperatures.

Why Sequence a Benzene-Degrading Methanogenic Consortium?  

NLE Websites -- All DOE Office Websites (Extended Search)

a Benzene-Degrading Methanogenic Consortium? a Benzene-Degrading Methanogenic Consortium? As recently as the 1990's, aromatic hydrocarbons like benzene and toluene were thought to be resistant to degradation under anaerobic conditions. It is now appreciated that biodegradation in the absence of oxygen contributes significantly to the attenuation of hydrocarbons and other pollutants in the environment. Unravelling the yet unknown pathways and mechanisms of anaerobic benzene metabolism is a critical milestone for hydrocarbon bioremediation. While many pathways have been suggested, none has been proven, and no genes or enzymes are known. The elucidation of this pathway, including the identification of the genes and enzymes involved, is vital for the demonstration, validation, and regulatory acceptance of in-situ

Fractionation of reformate: A new variant of gasoline production technology  

SciTech Connect

The Novo-Ufa Petroleum Refinery is the largest domestic producer of the unique high-octane unleaded automotive gasolines AI-93 and AI-95 and the aviation gasolines B-91/115 and B-92. The base component for these gasolines is obtained by catalytic reforming of wide-cut naphtha; this basic component is usually blended with certain other components that are expensive and in short supply: toluene, xylenes, and alkylate. For example, the unleaded gasoline AI-93 has been prepared by blending reformate, alkylate, and toluene in a 65:20:15 weight ratio; AI-95 gasoline by blending alkylate and xylenes in an 80:20 weight ratio; and B-91/115 gasoline by compounding a reformate obtained with light straight-run feed, plus alkylate and toluene, in a 55:35:10 weight ratio. Toluene and xylenes have been obtained by process schemes that include the following consecutive processes: redistillation of straight-run naphtha cuts to segregate the required narrow fraction; catalytic reforming (Platforming) of the narrow toluene-xylene straight-run fraction; azeotropic distillation of the reformate to recover toluene and xylenes. A new technology based on the use of reformate fractions is proposed.

Scoping benzene release measurements were conducted on 4 wt percent KTPB `DEMO` formulation slurry using a round, flat bottomed 100-mL flask containing 75 mL slurry. The slurry was agitated with a magnetic stirrer bar to keep the surface refreshed without creating a vortex. Benzene release measurements were made by purging the vapor space at a constant rate and analyzing for benzene by gas chromatography with automatic data acquisition. Some of the data have been rounded or simplified in view of the scoping nature of this study.

Toluene pyrolysis studies and high temperature reactions of propargyl chloride  

SciTech Connect

The main focus of this program is to investigate the thermal decompositions of fuels that play an important role in the pre-particle soot formation process. It has been demonstrated that the condition of maximum soot yield is established when the reaction conditions of temperature and pressure are sufficient to establish a radical pool to support the production of polyaromatic hydrocarbon species and the subsequent formation of soot particles. However, elevated temperatures result in lower soot yields which are attributed to thermolyses of aromatic ring structures and result in the bell-shaped dependence of soot yield on temperature. The authors have selected several acyclic hydrocarbons to evaluate the chemical thermodynamic and kinetic effects attendant to benzene formation. To assess the thermal stability of the aromatic ring, the authors have studied the pyrolyses of benzene, toluene, ethylbenzene, chlorobenzene and pyridine. Time-of-flight mass spectrometry (TOF) is employed to analyze the reaction zone behind reflected shock waves. Reaction time histories of the reactants, products, and intermediates are constructed and mechanisms are formulated to model the experimental data. The TOF work is often performed with use of laser schlieren densitometry (LS) to measure density gradients resulting from the heats of various reactions involved in a particular pyrolytic system. The two techniques, TOF and LS, provide independent and complementary information about ring formation and ring rupture reactions.

Fuel Dependence of Benzene Pathways  

SciTech Connect

The relative importance of formation pathways for benzene, an important precursor to soot formation, was determined from the simulation of 22 premixed flames for a wide range of equivalence ratios (1.0 to 3.06), fuels (C{sub 1}-C{sub 12}), and pressures (20 to 760 torr). The maximum benzene concentrations in 15 out of these flames were well reproduced within 30% of the experimental data. Fuel structural properties were found to be critical for benzene production. Cyclohexanes and C{sub 3} and C{sub 4} fuels were found to be among the most productive in benzene formation; and long-chain normal paraffins produce the least amount of benzene. Other properties, such as equivalence ratio and combustion temperatures, were also found to be important in determining the amount of benzene produced in flames. Reaction pathways for benzene formation were examined critically in four premixed flames of structurally different fuels of acetylene, n-decane, butadiene, and cyclohexane. Reactions involving precursors, such as C{sub 3} and C{sub 4} species, were examined. Combination reactions of C{sub 3} species were identified to be the major benzene formation routes with the exception of the cyclohexane flame, in which benzene is formed exclusively from cascading fuel dehydrogenation via cyclohexene and cyclohexadiene intermediates. Acetylene addition makes a minor contribution to benzene formation, except in the butadiene flame where C{sub 4}H{sub 5} radicals are produced directly from the fuel, and in the n-decane flame where C{sub 4}H{sub 5} radicals are produced from large alkyl radical decomposition and H atom abstraction from the resulting large olefins.

Steam reforming analyzed  

SciTech Connect

This paper reports that maximum steam reformer operation without excessive coking reactions requires careful control of thermodynamic and kinetic conditions. Regardless of the syngas-based feedstock composition, carbon formation problems can be avoided while increasing reformer CO or H{sub 2} production. Steam reforming technology is best understood via: Primary steam reformer developments, Kinetics of methane steam reforming, Simulation of an industrial steam/CO{sub 2} reformer, Example conditions (steam/CO{sub 2} reforming), Thermodynamic approach (minimum to steam ratio). Hydrogen and carbon monoxide are two of the most important building blocks in the chemical industry. Hydrogen is mainly used in ammonia and methanol synthesis and petroleum refining. Carbon monoxide is used to produce pains, plastics, foams, pesticides and insecticides, to name a few. Production of H{sub 2} and CO is usually carried out by the following processes: Steam reforming (primary and secondary) of hydrocarbons, Partial oxidation of hydrocarbons, Coal gasification. Coal gasification and partial oxidation do not use catalysts and depend on partial combustion of the feedstock to internally supply reaction heat. Secondary (autothermal) reforming is a type of steam reforming that also uses the heat of partial combustion but afterwards uses a catalyst of promote the production of hydrogen and CO.

Catalytic steam reforming of hydrocarbons  

SciTech Connect

The hot effluent from the catalytic steam reforming of a major portion of a fluid hydrocarbon feed stream in the reformer tubes of a primary reformer, or said effluent after secondary reforming thereof, is mixed with the hot effluent from the catalytic steam reforming of the remaining portion of the feed discharged from the reformer tubes of a primary reformer-exchanger. The combined gas steam is passed on the shell side of the reformer-exchanger countercurrently to the passage of feed in the reformer tubes thereof, thus supplying the heat for the reforming of the portion of the feed passed through the reformer tubes of the reformerexchanger. At least about 2/3 of the hydrocarbon feed stream is passed to the reformer tubes of said primary reformer, heated by radiant heat transfer and/or by contact with combustion gases, at a steam/hydrocarbon mole ratio of about 2-4/1. The remainder of said feed stream is passed to the reformer tubes of said reformer -exchanger at a steam/hydrocarbon mole ratio of about 3-6/1. The reformer shell of the reformer-exchanger is internally insulated by a refractory lining or by use of a double shell with passage of water or a portion of the feed material between the inner and outer shells. There is no significant difference between the pressure inside and outside of the reformer tubes of said primary reformer-exchanger.

SYNCHROTRON X-RAY MICROTOMOGRAPHY, ELECTRON PROBE MICROANALYSIS, AND NMR OF TOLUENE WASTE IN CEMENT.  

SciTech Connect

Synchrotron X-ray microtomography shows vesicular structures for toluene/cement mixtures, prepared with 1.22 to 3.58 wt% toluene. Three-dimensional imaging of the cured samples shows spherical vesicles, with diameters ranging from 20 to 250 {micro}m; a search with EPMA for vesicles in the range of 1-20 {micro}m proved negative. However, the total vesicle volume, as computed from the microtomography images, accounts for less than 10% of initial toluene. Since the cements were cured in sealed bottles, the larger portion of toluene must be dispersed within the cement matrix. Evidence for toluene in the cement matrix comes from {sup 29}Si MAS NMR spectroscopy, which shows a reduction in chain silicates with added toluene. Also, {sup 2}H NMR of d{sub 8}-toluene/cement samples shows high mobility for all, toluene and thus no toluene/cement binding. A model that accounts for all observations follows: For loadings below about 3 wt%, most toluene is dispersed in the cement matrix, with a small fraction of the initial toluene phase separating from the cement paste and forming vesicular structures that are preserved in the cured cement. Furthermore, at loadings above 3 wt%, the abundance of vesicles formed during toluene/cement paste mixing leads to macroscopic phase separation (most toluene floats to the surface of the cement paste).

Methane-steam reforming  

SciTech Connect

The literature relating to the kinetics of methane-steam reforming involving integral and differential reactor data, porous nickel catalysts and nickel foil, and data over large ranges of temperature (500 to 1700/sup 0/F), pressure (0.01 to 50 atm), and intrinsic catalyst activities (200,000-fold) was reviewed. A simple reversible first-order kinetic expression for the steam-methane reaction appears to be applicable throughout the operable region of steam-to-carbon ratios. Internal pore diffusion limitation on the conversion rate, due to catalyst size and/or intrinsic catalyst activity and total operating pressure was underlined. S-shaped Arrhenium plots (changing activation energy) are obtained when steam reforming is conducted over a temperature range sufficient to produce intrinsic kinetics (low temperature, inactive catalyst, or small catalyst size), pore diffusional limitations, and reaction on the outside surface. Homogeneous gas-phase kinetics appear to contribute only at relatively high temperature (1400/sup 0/F). In steam reforming, the water-gas shift reaction departs from its equilibrium position, especially at low methane conversion level. A general correlation of approach to water-gas shift equilibration as a function of conversion level only was indicated. (DP) 18 figures, 6 tables.

Kinetic Modeling of Toluene Oxidation for Surrogate Fuel Applications  

SciTech Connect

New environmental issues, like the effect of combustion-generated greenhouse gases, provide motivation to better characterize oxidation of hydrocarbons. Transportation, in particular, significantly contributes to energy consumption and CO{sub 2} emissions. Kinetic studies about the combustion of fuels under conditions typical of internal combustion engines provides important support to improve mechanism formulation and to eventually provide better computational tools that can be used to increase the engine performance. It is foreseeable that at least in the next 30 years the main transportation fuels will be either gasoline or diesel. Unfortunately, these fuels are very complex mixtures of many components. Moreover, their specifications and performance requirements significantly change the composition of these fuels: gasoline and diesel mixtures are different if coming from different refineries or they are different from winter to summer. At the same time a fuel with a well defined and reproducible composition is needed for both experimental and modeling work. In response to these issues, surrogate fuels are proposed. Surrogate fuels are defined as mixtures of a small number of hydrocarbons whose relative concentrations is adjusted in order to approximate the chemical and physical properties of a real fuel. Surrogate fuels are then very useful both for the design of reproducible experimental tests and also for the development of reliable kinetic models. The primary reference fuels (PRF) are a typical and old example of surrogate fuel: n-heptane and iso-octane mixtures are used to reproduce antiknock propensity of complex mixtures contained in a gasoline. PRFs are not able to surrogate gasoline in operating conditions different from standard ones and new surrogates have been recently proposed. Toluene is included in all of them as a species able to represent the behavior of aromatic compounds. On the other side, the toluene oxidation chemistry is not so well established and uncertainties still remain in the mechanism. This is especially true in the low temperature regime (< 850K). In these conditions, the toluene reactivity is too low to be conveniently investigated. Nonetheless, gasoline surrogates work in the engine at low temperatures, because of the presence of very reactive alkanes. The effect of these component interactions have to be taken into account. This work's aim is to present the model activity carried out by two different research groups, comparing the main pathways and results, matching data carried out in different devices both for pure toluene and mixtures. This is the starting point for a further activity to improve the two kinetic schemes.

New nickel-based material (Sr12Al14O33) for biomass tar steam reforming for syngas production  

Science Journals Connector (OSTI)

A new “free oxygen” material Sr12Al14O33 (Sr12A7) was developed as a Ni support for biomass tar steam reforming. Toluene was chosen as the model compound for biomass gasification tar. The steam reforming process was investigated in a fixed-bed reactor. The influence of the operating parameters (i.e. reaction temperature steam-to-carbon ratio and space time) on catalyst activity and product selectivity were studied. Ni/Sr12A7 (5?wt %) showed a higher activity compared with a similar commercial catalyst Ni/Dolomite. The influence of the steam/carbon (S/C) molar ratio on gas yields at values ranging from 1.5 to 4.0 was investigated. The results show that the H2 and CO2 yields increased whereas the CO yield decreased when the S/C ratio was increased. The influence of space-time (w cat/F toluene) was also determined. The H2 CO2 and total gas yields increased when the ratio was increased. Catalyst ageing experiments were characterized by Brunauer-Emmett-Teller (BET) X-ray diffraction (XRD) and energy dispersive X-ray spectrometer (EDX). Based on the results the kinetic model is proposed as a first-order reaction for toluene with an activation energy of 131.2?kJ·mol?1 as generally accepted in the literature.

Ultrasonic study of an emulsion of toluene in water  

Science Journals Connector (OSTI)

Previously reported ultrasonic attenuation results in the frequency range 4 to 50 MHz and theoretical predictions [J. R. Allegra and S. A. Hawley J. Acoust. Soc. Am. 51 1545 (1971)] for an emulsion of toluene in water have indicated that the observed excess attenuation in the measured frequency range was largely due to heat conduction losses. In the present paper ultrasonicabsorptionmeasurements on a 20% emulsion of toluene in water in the frequency range 1 to 135 MHz at 25 °C are described. The excess attenuation due to the emulsion globules as a function of frequency was compared with explicit expressions for heat conduction viscous drag losses and scattering of sound by emulsion globules. Unlike the previous work the agreement between theoretically predicted excess attenuation and that observed can only be obtained if a wide distribution of globule sizes was assumed. The assumption of a globule size distribution spanning from 600 to 6000 Å in diameter produced a theoretical curve in good agreement with the observed excess absorption over the entire frequency range.

Applications of solar reforming technology  

SciTech Connect

Research in recent years has demonstrated the efficient use of solar thermal energy for driving endothermic chemical reforming reactions in which hydrocarbons are reacted to form synthesis gas (syngas). Closed-loop reforming/methanation systems can be used for storage and transport of process heat and for short-term storage for peaking power generation. Open-loop systems can be used for direct fuel production; for production of syngas feedstock for further processing to specialty chemicals and plastics and bulk ammonia, hydrogen, and liquid fuels; and directly for industrial processes such as iron ore reduction. In addition, reforming of organic chemical wastes and hazardous materials can be accomplished using the high-efficiency destruction capabilities of steam reforming. To help identify the most promising areas for future development of this technology, we discuss in this paper the economics and market potential of these applications.

Sarcosine attenuates toluene-induced motor incoordination, memory impairment, and hypothermia but not brain stimulation reward enhancement in mice  

SciTech Connect

Toluene, a widely used and commonly abused organic solvent, produces various behavioral disturbances, including motor incoordination and cognitive impairment. Toluene alters the function of a large number of receptors and ion channels. Blockade of N-methyl-D-aspartate (NMDA) receptors has been suggested to play a critical role in toluene-induced behavioral manifestations. The present study determined the effects of various toluene doses on motor coordination, recognition memory, body temperature, and intracranial self-stimulation (ICSS) thresholds in mice. Additionally, the effects of sarcosine on the behavioral and physiological effects induced by toluene were evaluated. Sarcosine may reverse toluene-induced behavioral manifestations by acting as an NMDA receptor co-agonist and by inhibiting the effects of the type I glycine transporter (GlyT1). Mice were treated with toluene alone or combined with sarcosine pretreatment and assessed for rotarod performance, object recognition memory, rectal temperature, and ICSS thresholds. Toluene dose-dependently induced motor incoordination, recognition memory impairment, and hypothermia and lowered ICSS thresholds. Sarcosine pretreatment reversed toluene-induced changes in rotarod performance, novel object recognition, and rectal temperature but not ICSS thresholds. These findings suggest that the sarcosine-induced potentiation of NMDA receptors may reverse motor incoordination, memory impairment, and hypothermia but not the enhancement of brain stimulation reward function associated with toluene exposure. Sarcosine may be a promising compound to prevent acute toluene intoxications by occupational or intentional exposure. -- Highlights: ? Toluene induces impairments in Rotarod test and novel object recognition test. ? Toluene lowers rectal temperature and ICSS thresholds in mice. ? Sarcosine reverses toluene-induced changes in motor, memory and body temperature. ? Sarcosine pretreatment does not affect toluene-induced reward enhancement.

Recover heat from steam reforming  

SciTech Connect

Steam reforming is one of the most important chemical processes--it is used in the manufacture of ammonia, hydrogen, methanol, and many chemicals made from hydrogen and carbon monoxide. Furthermore, many current trends will increase its importance. For example, methanol for addition to gasoline is likely to be produced by steam reforming. Because steam reforming occurs at high temperatures--typically 750 C--900 C--it generates a large amount of waste heat. Clearly, heat recovery is crucial to process economics. A typical 50,000 Nm[sup 3]/h hydrogen plant using natural gas feed has a radiant heat duty of about 50 MW. At a radiant efficiency of 50% and fuel cost of $3/GJ, this means that the reformer fires $9 million worth of fuel per year. Obviously, this amount of fuel justifies a close loot at ways to reduce costs. This article first provides a brief overview of steam reforming. It then outlines the available heat-recovery options and explains how to select the best method.

Hydrogen Generation Via Fuel Reforming  

Science Journals Connector (OSTI)

Reforming is the conversion of a hydrocarbon based fuel to a gas mixture that contains hydrogen. The H2 that is produced by reforming can then be used to produce electricity via fuel cells. The realization of H2?based power generation via reforming is facilitated by the existence of the liquid fuel and natural gas distribution infrastructures. Coupling these same infrastructures with more portable reforming technology facilitates the realization of fuel cell powered vehicles. The reformer is the first component in a fuel processor. Contaminants in the H2?enriched product stream such as carbon monoxide (CO) and hydrogen sulfide (H2S) can significantly degrade the performance of current polymer electrolyte membrane fuel cells (PEMFC’s). Removal of such contaminants requires extensive processing of the H2?rich product stream prior to utilization by the fuel cell to generate electricity. The remaining components of the fuel processor remove the contaminants in the H2 product stream. For transportation applications the entire fuel processing system must be as small and lightweight as possible to achieve desirable performance requirements. Current efforts at Argonne National Laboratory are focused on catalyst development and reactor engineering of the autothermal processing train for transportation applications.

The thermal plasma is a highly energetic state of matter that is characterized by extremely high temperatures (several thousand degrees Celsius), and a high degree of dissociation and a substantial degree of ionization. The high temperatures accelerate the reactions involved in the reforming process. Hydrogen-rich gas (40% H2, 17% CO2 and 33% N2, for partial oxidation/water shifting) can be efficiently made in compact plasma reformers. Experiments have been carried out in a small device (2–3 kW) and without the use of efficient heat regeneration. For partial oxidation/water shifting, it was determined that the specific energy consumption in the plasma reforming processes is 16 MJ/kg H2 with high conversion efficiencies. Larger plasmatrons, better reactor thermal insulation, efficient heat regeneration and improved plasma catalysis could also play a major role in specific energy consumption reduction and increasing the methane conversion. A system has been demonstrated for hydrogen production with low CO content (?1.5%) with power densities of ?30 kW (H2 HHV)/l of reactor, or ?10 m3/h H2 per liter of reactor. Power density should further increase with increased power and improved design.

What Determines the Likelihood of Structural Reforms?  

Science Journals Connector (OSTI)

Abstract We use data for a panel of 60 countries over the period 1980-2005 to investigate the main drivers of the likelihood of structural reforms. We find that: (i) external debt crises are the main trigger of financial and banking reforms; (ii) inflation and banking crises are the key drivers of external capital account reforms; (iii) banking crises also hasten financial reforms; and (iv) economic recessions play an important role in promoting the necessary consensus for financial, capital, banking and trade reforms, especially in the group of OECD-countries. Additionally, we also observe that the degree of globalisation is relevant for financial reforms, in particular in the group of non-OECD countries. Moreover, an increase in the income gap accelerates the implementation of structural reforms, but increased political fragmentation does not seem to have a significant impact.

Conversion of hydrocarbons for fuel-cell applications. Part I. Autothermal reforming of sulfur-free and sulfur-containing hydrocarbon liquids. Part II. Steam reforming of n-hexane on pellet and monolithic catalyst beds. Final report  

SciTech Connect

Experimental autothermal reforming (ATR) results obtained in the previous phase of this work with sulfur-free pure hydrocarbon liquids are summarized. Catalyst types and configuration used were the same as in earlier tests with No. 2 fuel oil to facilitate comparisons. Fuel oil has been found to form carbon in ATR at conditions much milder than those predicted by equilibrium. Reactive differences between paraffins and aromatics in ATR, and thus the formation of different carbon precursors, have been shown to be responsible for the observed carbon formation characteristics (fuel-specific). From tests with both light and heavy paraffins and aromatics, it is concluded that high boiling point hydrocarbons and polynuclear aromatics enhance the propensity for carbon formation in ATR. Effects of olefin (propylene) addition on the ATR performance of benzene are described. In ATR tests with mixtures of paraffins and aromatics (n-tetradecane and benzene) synergistic effects on conversion characteristics were identified. Comparisons of the No. 2 fuel oil data with the experimental results from this work with pure (and mixed) sulfur-free hydrocarbons indicate that the sulfur content of the fuel may be the limiting factor for efficient ATR operation. Steam reforming of hydrocarbons in conventional reformers is heat transfer limited. Steam reforming tasks performed have included performance comparisons between conventional pellet beds and honeycomb monolith catalysts. Metal-supported monoliths offer higher structural stability than ceramic supports, and have a higher thermal conductivity. Data from two metal monoliths of different catalyst (nickel) loading were compared to pellets under the same operating conditions.

Evaluation of the In Situ Aerobic Cometabolism of Chlorinated Ethenes by Toluene-Utilizing Microorganisms Using Push-Pull Tests  

SciTech Connect

Single-well-push-pull tests were used in a contaminated aquifer to evaluate the ability of toluene-oxidizing microorganisms to aerobically cometabolize chlorinated aliphatic hydrocarbons (CAHs) such as trichloroethene (TCE). Groundwater containing dissolved toluene was injected into the saturated zone in biostimulate indigenous toluene-utilizers. The test solution was injected into the aquifer using a standard monitoring well and then was transported under natural-gradient conditions. Transport tests demonstrated similar transport characteristics of the conservative tracer and the reactive solutes. Biostimulation tests were then performed by injecting a test solution containing dissolved toluene substrate, hydrogen peroxide, bromide and nitrate in order to increase the biomass of toluene-utilizing microorganisms. During the biostimulation tests, decreases in toluene concentration and the production of o-cresol as an intermediate oxidation product, indicated the simulation of toluene-utilizing microorganisms containing an ortho-monooxygenase enzyme. Transformation tests conducted after biostimulation demonstrated that indigenous microorganisms have the capability to transform the surrogate compounds (e.g. isobutene). Isobutene was transformed to isobutene oxide, indicating transformation by a toluene ortho-monooxygenase.

Stable Carbon Isotope Ratios of Phenolic Compounds in Secondary Particulate Organic Matter Formed by Photooxidation of Toluene  

E-Print Network (OSTI)

Compound-specific stable carbon isotope ratios for phenolic compounds in secondary particulate organic matter (POM) formed by photooxidation of toluene were studied. Secondary POM generated by photooxidation of toluene using a continuous-flow reactor and an 8 cubic meter indoor smog chamber was collected, and then extracted with acetonitrile. Eight phenolic compounds were identified in the extracts by a gas chromatograph coupled with a mass spectrometer, and their compound-specific stable carbon isotope ratios were determined by a gas chromatograph coupled with a combustion furnace followed by an isotope ratio mass spectrometer. The majority of the products, including methylnitrophenols and methylnitrocatechols, were isotopically depleted by 5 to 6 permil compared to the initial isotope ratio for toluene, whereas the isotope ratio for 4_nitrophenol remained the same as the initial isotope ratio for toluene. Based on the reaction mechanisms postulated in literature, stable carbon isotope ratios of these produc...

Effects of welfare reform on women's crime  

Science Journals Connector (OSTI)

Abstract We investigate the effects of broad-based work incentives on female crime by exploiting the welfare reform legislation of the 1990s, which dramatically increased employment among women at risk for relying on cash assistance. We base the analyses on the supply of crime model in the human capital literature which emphasizes the importance of employment prospects in the legal and illegal labor markets. We find suggestive evidence that welfare reform decreased female arrests for property crimes (by 4–5%), but that it did not affect arrests for other types of crimes. The effects appear to be stronger in states with larger welfare caseload declines. As welfare reform policies are targeted to females, it is empirically validating that we do not find any substantively or statistically significant effects of welfare reform on crime among males. The findings point to broad-based work incentives—and, by inference, employment—as an important determinant of female property crime.

Physician payments under health care reform  

Science Journals Connector (OSTI)

Abstract This study examines the impact of major health insurance reform on payments made in the health care sector. We study the prices of services paid to physicians in the privately insured market during the Massachusetts health care reform. The reform increased the number of insured individuals as well as introduced an online marketplace where insurers compete. We estimate that, over the reform period, physician payments increased at least 11 percentage points relative to control areas. Payment increases began around the time legislation passed the House and Senate—the period in which their was a high probability of the bill eventually becoming law. This result is consistent with fixed-duration payment contracts being negotiated in anticipation of future demand and competition.

Improve reformer operation with trace sulfur removal  

SciTech Connect

Modern bimetallic reforming catalysts typically have feed specifications for sulfur of 0.5 to 1 wppm in the reformer naphtha carge. Sulfur in the raw naphtha is reduced to this level by naphtha hydrotreating. While most naphtha hydrotreating operations can usually obtain these levels without substantial problems. It is difficult to obtain levels much below 0.5 to 1 wppm with this process. Revamp of a constrained existing hydrotreater to reduce product sulfur slightly can be extremely costly typically entailing replacement or addition of a new reactor. At Engelhard the authors demonstrated that if the last traces of sulfur remaining from hydrotreating can be removed, the resulting ultra-low sulfur feed greatly improves the reformer operation and provides substantial economic benefit to the refiner. Removal of the remaining trace sulfur is accomplished in a simple manner with a special adsorbent bed, without adding complexity to the reforming operation.

Toluene effects on oxidative stress in brain regions of young-adult, middle-age, and senescent Brown Norway rats  

Science Journals Connector (OSTI)

The influence of aging on susceptibility to environmental contaminants is not well understood. To extend knowledge in this area, we examined effects in rat brain of the volatile organic compound, toluene. The objective was to test whether oxidative stress (OS) plays a role in the adverse effects caused by toluene exposure, and if so, if effects are age-dependent. OS parameters were selected to measure the production of reactive oxygen species (NADPH Quinone oxidoreductase 1 (NQO1), NADH Ubiquinone reductase (UBIQ-RD)), antioxidant homeostasis (total antioxidant substances (TAS), superoxide dismutase (SOD), ?-glutamylcysteine synthetase (?-GCS), glutathione transferase (GST), glutathione peroxidase (GPX), glutathione reductase (GRD)), and oxidative damage (total aconitase and protein carbonyls). In this study, Brown Norway rats (4, 12, and 24 months) were dosed orally with toluene (0, 0.65 or 1 g/kg) in corn oil. Four hours later, frontal cortex, cerebellum, striatum, and hippocampus were dissected, quick frozen on dry ice, and stored at ? 80 °C until analysis. Some parameters of OS were found to increase with age in select brain regions. Toluene exposure also resulted in increased OS in select brain regions. For example, an increase in NQO1 activity was seen in frontal cortex and cerebellum of 4 and 12 month old rats following toluene exposure, but only in the hippocampus of 24 month old rats. Similarly, age and toluene effects on glutathione enzymes were varied and brain-region specific. Markers of oxidative damage reflected changes in oxidative stress. Total aconitase activity was increased by toluene in frontal cortex and cerebellum at 12 and 24 months, respectively. Protein carbonyls in both brain regions and in all age groups were increased by toluene, but step-down analyses indicated toluene effects were statistically significant only in 12 month old rats. These results indicate changes in OS parameters with age and toluene exposure resulted in oxidative damage in frontal cortex and cerebellum of 12 month old rats. Although increases in oxidative damage are associated with increases in horizontal motor activity in older rats, further research is warranted to determine if these changes in OS parameters are related to neurobehavioral and neurophysiological effects of toluene in animal models of aging.

Biogas fuel reforming for solid oxide fuel cells  

Science Journals Connector (OSTI)

In this paper strategies for biogas reforming and their ensuing effects on solid oxide fuel cell(SOFC) performance are explored. Synthesized biogas (65% CH4?+?35% CO2) fuel streams are reformed over a rhodium catalyst supported on a porous ?-alumina foam. Reforming approaches include steam reforming and catalytic partial oxidation (CPOX) utilizing either air or pure oxygen as the oxidant. A computational model is developed and utilized to guide the specification of reforming conditions that maximize both CH4 and CO2 conversions. Model predictions are validated with experimental measurements over a wide range of biogas-reforming conditions. Higher reforming temperatures are shown to activate the biogas-borne CO2 to enable significant methane dry-reforming chemistry. Dry reforming minimizes the oxidant-addition needs for effective biogas conversion potentially decreasing the thermal requirements for reactant heating and improving system efficiency. Such high-temperature reforming conditions are prevalent during CPOX with a pure-O2 oxidant. While CPOX-with-O2 reforming is highly exothermic the endothermicity of dry-reforming chemistry can be exploited to ensure that catalyst temperatures do not reach levels which cause catalyst sintering and degradation. SOFCelectrochemical performance under biogas reformate is shown to vary substantially with reforming approach. Cell operation under CPOX-with-O2 reformate is found to be comparable to that under humidified hydrogen.

Reforming of fuel inside fuel cell generator  

DOE Patents (OSTI)

Disclosed is an improved method of reforming a gaseous reformable fuel within a solid oxide fuel cell generator, wherein the solid oxide fuel cell generator has a plurality of individual fuel cells in a refractory container, the fuel cells generating a partially spent fuel stream and a partially spent oxidant stream. The partially spent fuel stream is divided into two streams, spent fuel stream I and spent fuel stream II. Spent fuel stream I is burned with the partially spent oxidant stream inside the refractory container to produce an exhaust stream. The exhaust stream is divided into two streams, exhaust stream I and exhaust stream II, and exhaust stream I is vented. Exhaust stream II is mixed with spent fuel stream II to form a recycle stream. The recycle stream is mixed with the gaseous reformable fuel within the refractory container to form a fuel stream which is supplied to the fuel cells. Also disclosed is an improved apparatus which permits the reforming of a reformable gaseous fuel within such a solid oxide fuel cell generator. The apparatus comprises a mixing chamber within the refractory container, means for diverting a portion of the partially spent fuel stream to the mixing chamber, means for diverting a portion of exhaust gas to the mixing chamber where it is mixed with the portion of the partially spent fuel stream to form a recycle stream, means for injecting the reformable gaseous fuel into the recycle stream, and means for circulating the recycle stream back to the fuel cells.

Low Cost Autothermal Diesel Reforming Catalyst Development  

SciTech Connect

Catalytic autothermal reforming (ATR) represents an important step of converting fossil fuel to hydrogen rich reformate for use in solid oxide fuel cell (SOFC) stacks. The state-of-the-art reforming catalyst, at present, is a Rh based material which is effective but costly. The objective of our current research is to reduce the catalyst cost by finding an efficient ATR catalyst containing no rhodium. A group of perovskite based catalysts have been synthesized and evaluated under the reforming condition of a diesel surrogate fuel. Hydrogen yield, reforming efficiency, and conversion selectivity to carbon oxides of the catalyst ATR reaction are calculated and compared with the benchmark Rh based material. Several catalyst synthesis improvements were carried out including: 1) selectively doping metals on the A-site and B-site of the perovskite structure, 2) changing the support from perovskite to alumina, 3) altering the method of metal addition, and 4) using transition metals instead of noble metals. It was found that the catalytic activity changed little with modification of the A-site metal, while it displayed considerable dependence on the B-site metal. Perovskite supports performed much better than alumina based supports.

Simulation of Steam Reformers for Methane  

Science Journals Connector (OSTI)

Abstract A model is developed for industrial steam reformers for both top fired and side fired furnaces. The catalyst tube model is a one-dimensional heterogeneous model with intra-particle diffusional resistances. The two point boundary value differential equations of the catalyst pellets are solved using a modified novel orthogonal collocation technique to obtain the effectiveness factor variation along the length of the reactor. The side fired furnace equations are algebraic equations, the top fired furnace equations are two-point boundary value differential equations which are solved using the orthogonal collocation technique. A recently developed more general rate expression is used. The model performance is checked against industrial steam reformers. The model is used to investigate the effect of various parameters on the behaviour of the catalyst tubes and the furnace. The effectiveness factor variation along the length of the catalyst tube is also analysed. Keywords: Steam Reforming, Reactor modeling, Digital Simulation, effectiveness factor

308 nm photochemical reaction of gaseous HNO3 and benzene on ?-Fe2O3 surfaces  

Science Journals Connector (OSTI)

Abstract The 308 nm photochemical reactions of nitric acid (HNO3) and benzene in the gas phase and on ?-Fe2O3 surface at 298 K was investigated by using Fourier transform infrared spectroscopy (FT-IR) combined with high performance liquid chromatography (HPLC). The concentration and yield of HONO and p-nitrophenol (p-NP) had been examined as a function of reaction time, benzene initial concentration and relative humidity on photochemical reaction. The results showed that gaseous HNO3 did not directly react with benzene in the dark, and p-NP was formed irradiation under 308 nm UV light. When HNO3 initial concentration was 400 Pa and benzene was 300 Pa, the illumination time was 100 min, the concentration of p-NP produced from the photochemical reaction of HNO3 and benzene on ?-Fe2O3 surface was about 3.08 times higher than that in the gas phase. In the meantime, while reaction time was 40 min and relative humidity was 70%, the concentration of HONO and p-NP formed on ?-Fe2O3 surface were about 3.55 and 2.51 times higher than those in the gas phase, and the yield of p-NP was 3.74% and 2.99%, respectively. Surfaces effect played a leading role in photochemical reaction of HNO3 and benzene on ?-Fe2O3 surface.

Alternative technologies to steam-methane reforming  

SciTech Connect

Steam-methane reforming (SMR) has been the conventional route for hydrogen and carbon monoxide production from natural gas feedstocks. However, several alternative technologies are currently finding favor for an increasing number of applications. The competing technologies include: steam-methane reforming combined with oxygen secondary reforming (SMR/O2R); autothermal reforming (ATR); thermal partial oxidation (POX). Each of these alternative technologies uses oxygen as a feedstock. Accordingly, if low-cost oxygen is available, they can be an attractive alternate to SMR with natural gas feedstocks. These technologies are composed technically and economically. The following conclusions can be drawn: (1) the SMR/O2R, ATR and POX technologies can be attractive if low-cost oxygen is available; (2) for competing technologies, the H{sub 2}/CO product ratio is typically the most important process parameter; (3) for low methane slip, the SMR/O2R, ATR and POX technologies are favored; (4) for full CO{sub 2} recycle, POX is usually better than ATR; (5) relative to POX, the ATR is a nonlicensed technology that avoids third-party involvement; (6) economics of each technology are dependent on the conditions and requirements for each project and must be evaluated on a case-by-case basis.

Carbon deposition in steam reforming and methanation  

SciTech Connect

The purpose of this review is to survey recent studies of carbon deposition on metals used as catalysts in steam reforming and methanation, emphasizing research where significant progress has been made. Where possible, an attempt is made to treat the fundamental nature of carbon formation and deactivation by carbon and the relationships between these two phenomena. Steam reforming and methanation are emphasized in this review because (1) deactivation of catalysts by carbon deposits is a serious concern in both processes, (2) much of the previous research with carbon formation on metals involved one or the other of these two reactions, and (3) there are interesting differences and similarities between these two reactions; for example, methanation is typically carried out at moderate reaction temperatures (200-450/sup 0/C) while steam reforming is typically carried out at significantly higher reaction temperatures (600-900/sup 0/C). Yet the two reactions are very closely related, since methane steam reforming is the reverse of methanation of CO. Moreover, there is evidence that some of the carbons formed in these two different processes are similar in their morphology.

A process is described for producing ammonia which comprises: (a) primary catalytically reforming at super atmospheric pressure in a direct-fired primary reforming zone, a hydrocarbon feedstock with steam to produce a gas containing carbon oxides, hydrogen and methane; (b) secondary catalytically reforming the gas from step (a) by introducing air and bringing the mixture towards equilibrium thereby producing a secondary reformer effluent gas containing nitrogen, carbon oxides, hydrogen and a decreased quantity of methane; (c) converting carbon monoxide catalytically with steam to carbon dioxide and hydrogen; (d) removing carbon oxides to give an ammonia synthesis gas comprising nitrogen and hydrogen and compressing the gas to ammonia synthesis pressure; (e) reacting the synthesis gas in an ammonia synthesis zone to produce ammonia and recovering ammonia from the reacted gas to produce an ammonia-depleted gas stream; (f) recycling at least a portion of the ammonia-depleted gas stream to the ammonia synthesis zone; and (g) treating a sidestream of the ammonia-depleted gas to separate a stream enriched in hydrogen and an inerts-enriched gas stream, and returning the enriched hydrogen stream to the ammonia synthesis zone.

Test of electron beam technology on Savannah River Laboratory low-activity aqueous waste for destruction of benzene, benzene derivatives, and bacteria  

SciTech Connect

High energy radiation was studied as a means for destroying hazardous organic chemical wastes. Tests were conducted at bench scale with a {sup 60}Co source, and at full scale (387 l/min) with a 1.5 MV electron beam source. Bench scale tests for both benzene and phenol included 32 permutations of water quality factors. For some water qualities, as much as 99.99% of benzene or 90% of phenol were removed by 775 krads of {sup 60}Co irradiation. Full scale testing for destruction of benzene in a simulated waste-water mix showed loss of 97% of benzene following an 800 krad dose and 88% following a 500 krad dose. At these loss rates, approximately 5 Mrad of electron beam irradiation is required to reduce concentrations from 100 g/l to drinking water quality (5 {mu}g/l). Since many waste streams are also inhabited by bacterial populations which may affect filtering operations, the effect of irradiation on those populations was also studied. {sup 60}Co and electron beam irradiation were both lethal to the bacteria studied at irradiation levels far lower than were necessary to remove organic contaminants.

Evaluation of the economic and environmental impact of combining dry reforming with steam reforming of methane  

Science Journals Connector (OSTI)

Lately, there has been considerable interest in the development of more efficient processes to generate syngas, an intermediate in the production of fuels and chemicals, including methanol, dimethyl ether, ethylene, propylene and Fischer–Tropsch fuels. Steam methane reforming (SMR) is the most widely applied method of producing syngas from natural gas. Dry reforming of methane (DRM) is a process that uses waste carbon dioxide to produce syngas from natural gas. Dry reforming alone has not yet been implemented commercially; however, a combination of steam methane reforming and dry reforming of methane (SMR + DRM) has been used in industry for several years. The aim of this work was to simulate both the SMR and SMR + DRM processes and to conduct an economic and environmental analysis to determine whether the SMR + DRM process is competitive with the more popular SMR process. The results indicate that the SMR + DRM process has a lower carbon footprint. Further research on DRM catalysts could make this process economically competitive with steam methane reforming.

Analysis of the catalysts suggested that the hydrotalcite precursor after thermal treatment lead to a good dispersion of nickel forming the solid solution NiO-MgO and spinel (Ni,Mg)Al{sub 2}O{sub 4}. The promoted catalysts had higher oxygen permeation flux, better catalytic activity, and better resistance to carbon formation, which will be promising catalysts in the catalytic partial oxidation reforming of hot COG. 29 refs., 11 figs., 2 tabs.

Structural and regulatory reform in Turkey: Lessons form public utilities  

Science Journals Connector (OSTI)

Abstract Turkey is one of the countries that recently initiated regulatory reform in public utilities. Although Turkey tried to introduce competition to many industries through a liberalization movement that started in the 1980s, utilities remained as monopolies until the early 2000s. In the beginning of the 2000s, reforms restructured the utilities through deregulation and competition policies and established independent regulatory agencies. Whereas the reforms have been successful in some aspects, they remain insufficient in others. This paper anecdotally investigates the effects of (de)regulation on selected public utility industries and analyzes the pros and cons of the reform process. Also, it presents a comparative analysis to better understand the current institutional and governmental issues in the reform process. The findings suggest that the recently changing stance of government towards the (de)regulatory process could thwart the success of reform.

On the performance and mechanisms of toluene removal by FeOx/SBA-15-assisted non-thermal plasma at atmospheric pressure and room temperature  

Science Journals Connector (OSTI)

Abstract FeOx/SBA-15 catalysts were prepared via impregnation and utilized for toluene removal in dielectric barrier discharge (DBD) plasma at atmospheric pressure and room temperature. Toluene removal was investigated in the environment of various mixed N2/O2 plasmas, showing that toluene removal efficiency and \\{COx\\} selectivity were greatly increased by FeOx/SBA-15 and that the organic intermediates were greatly reduced by catalysts. In pure N2 plasma, the bulk oxygen in the catalyst was involved in the toluene oxidation, and the 3%FeOx/SBA-15 catalyst showed the optimal toluene oxidation activity. The catalysts were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), N2 adsorption–desorption, X-ray photoelectron spectroscopy (XPS), H2 temperature-programmed reduction (H2-TPR) and O2 temperature-programmed desorption (O2-TPD), showing that toluene oxidation was closely related to the highly dispersed nature of iron on the SBA-15 surface, the reduction temperature of Fe2+ and the oxygen adsorption ability of the catalyst. The pathways of toluene decomposition in the combination of FeOx/SBA-15 with a non-thermal plasma (NTP) system were proposed based on the identified intermediates.

Science Journals Connector (OSTI)

Three basic concepts of solid oxide fuel cell (SOFC) systems operating on hydrocarbon fuels, with external, internal, and partial prereforming, respectively, are presented and discussed. Internal reforming of methane is advantageously used for additional cooling of the SOFC stack, thus increasing system efficiency. Basic thermodynamics, catalysis, and kinetics of the methane steam reforming process are presented. Examples of SOFC stacks operating on internal reforming of methane and simulated partial prereforming of mine gas and natural gas are discussed. The latter is used to illustrate the effect of internal methane reforming on heat management in SOFC stacks.

Organosulfur chemistry on W(211) surfaces. 2. A comparison of benzene, thiophene, and tetrahydrothiophene  

SciTech Connect

The interactions of benzene, thiophene, and tetrahydrothiophene with clean, oxidized, and sulfided W(211) surfaces were studied with LEED, AES, and temperature programmed reaction. Benzene and thiophene appear to absorb as bases making -bonds to the surface. Benzene decomposed to yield adsorbed carbon and hydrogen. Thiophene appeared to undergo electrophilic attack at the 2-position forming a carbon bound surface intermediate. This surface intermediate was desulfurized and the resulting hydrocarbon surface intermediate underwent C-C bond scission forming C3 hydrocarbons as the dominate desorption product. The electrophilic attack at the 2-position was shown by methyl group elimination from 2,5-dimethylthiophene. Adsorbed oxygen and sulfur enhanced the adsorption of benzene and thiophene by making the surface more acidic. Tetrahydrothiophene (THT) appear to adsorb as a base, forming a bond between the S(3p) electrons and the surface. Desulfurization of adsorbed THT led to C4 hydrocarbons as the dominate desorption product. Adsorbed oxygen and sulfur inhibited reaction of THT. These results suggest that the surface reactivity and subsequent desulfurization of thiophene is controlled by electrophilic attack on the aromatic ring, and the ensuing reduction of resonance stabilization facilitates sulfur removal. 41 references, 8 figures, 4 tables.

Accurately modeling benzene and alkylbenzenes using a group contribution based SAFT approach  

Science Journals Connector (OSTI)

Abstract In recent work, the GC-SAFT-VR equation, which combines the SAFT equation for potentials of variable range (VR) with a group contribution (GC) approach, was proposed. Parameters for key functional groups (such as CH3, CH2, CH, CH2CH, CO, C6H5, ether, ester, OH, NH2, CHO, COOH) were obtained by fitting to experimental vapor pressure and saturated liquid density data for selected low molecular weight fluids and then used to predict the phase behavior of both pure non-associating and associating fluids and their mixtures, generally without adjusting the group parameters to binary mixture data. In the GC-SAFT-VR approach the benzene ring was modeled as a single group (C6H6 for benzene and C6H5, for alkylbenzenes) however, in common with other group-contribution based SAFT approaches, this approach fails to reproduce the correct curvature seen in the experimental liquid density of alkylbenzenes. In this work, to improve upon the model adopted for ring molecules, the benzene ring is explicitly considered through the connectivity of several smaller groups to more accurately capture the ?–? interactions. We demonstrate that the improved model better captures the curvature present in the experimental saturated liquid density data of pure alkylbenzenes. Additionally, mixtures of several non-associating and associating fluids with benzene and alklybenzenes are studied.

Effects of Current upon Electrochemical Catalytic Reforming of Anisole  

Science Journals Connector (OSTI)

The reforming of anisole (as model compound of bio-oil) was performed over the NiCuZn-Al2O3 catalyst, using a recently-developed electrochemical catalytic reforming (ECR). The influence of the current on the anisole reforming in the ECR process has been investigated. It was observed that anisole reforming was significantly enhanced by the current approached over the catalyst in the electrochemical catalytic process, which was due to the non-uniform temperature distribution in the catalytic bed and the role of the thermal electrons originating from the electrified wire. The maximum hydrogen yield of 88.7% with a carbon conversion of 98.3% was obtained through the ECR reforming of anisole at 700°C and 4 A. X-ray diffraction was employed to characterize catalyst features and their alterations in the anisole reforming. The apparent activation energy for the anisole reforming is calculated as 99.54 kJ/mol, which is higher than ethanol, acetic acid, and light fraction of bio-oil. It should owe to different physical and chemical properties and reforming mechanism for different hydrocarbons.

Telecommunications reform and efficiency performance: Do good institutions matter?  

Science Journals Connector (OSTI)

Abstract Until recently, most studies investigating telecommunication reforms performance have failed to incorporate the importance of institutions into the empirical analysis. This study highlights the importance of institutional governance on telecommunications efficiency and provides empirical results for the impact of institutions on reform outcomes. It provides significant evidence that the institutional environment in which reform progress takes place is an important determinant for successful reform. This study uses the stochastic distance function approach to capture the role of institutions in explaining efficiency differences across 70 countries. The empirical analysis reveals that policy stability in the form of substantive checks and balances on executive power is the most important aspect for successful reform. Independently, legal integrity improves telecommunications efficiency through privatization, while greater freedom from corruption influences the effectiveness of a regulatory body.

Steam reformers heated by helium from high temperature reactors  

Science Journals Connector (OSTI)

The manifold possibilities of the application of helium-heated steam reformers combined with high temperature nuclear reactors are elucidated in this article. It is shown that the thermodynamic interpretation of the processes does not cause difficulties because of the good heat transfer in helium at high pressure and that helium peak temperatures of 950°C are sufficient for carrying out the process. The mechanical design of the reformer tube does not lead to problems because the helium and process pressures are so chosen as to be approximately equal. The problems of hydrogen and tritium permeation as well as the contamination of the reformer tube with solid fission products seem to be solvable using the knowledge available at present. Furthermore, the various possibilities for the design arrangements of helium-heated reformer tube furnaces are shown. The status of development attained to date is outlined and in conclusion there is a survey regarding the next steps to be taken in steam reformer technology.

For production of synthesis gas from natural gas the steam reforming process is still the most economical. It generates synthesis gas for ammonia and methanol production as well as hydrogen, oxo gas and town gas. After desulfurization, the natural gas is mixed with steam and fed to the reforming furnace where decomposition of hydrocarbons takes place in the presence of a nickel-containing catalyst. Synthesis gas that must be free of CO and CO/sub 2/ is further treated in a CO shift conversion, a CO/sub 2/ scrubbing unit and a methanation unit. The discussion covers the following topics - reforming furnace; the outlet manifold system; secondary reformer; reformed gas cooling. Many design details of equipment used are given.

Catalyst for steam reforming of hydrocarbons  

SciTech Connect

A catalyst's resistance to deactivation by polymer formation is vital to the successful gasification of heavy feedstocks such as kerosene and gas oil. The improved polymer-resistance performance of this steam-reforming catalyst is directly relate to the distribution of the pore sizes in its calcined (but unreduced) precursor form and to a certain pore-size ratio: 1) At least 55% of the pore volume of pores having a radius of between 12 and 120 A(2000A) is in the range of 12-30 A(2000A) and 2) the ratio of the pore volume contained in pores of 10-50 A(2000A) to the volume contained in pores of 50-300 A(2000A) is at least 5:1. The catalyst-preparation method involves coprecipitation with a minimum of heat treatment (at temperatures not greater than 140/sup 0/F or 60/sup 0/C).

Performance tests for steam methane reformers  

SciTech Connect

Most of the synthesis gas plants in operation in the United States for production of hydrogen, carbon monoxide, methanol, and ammonia use steam methane reforming (SMR). Economic projections indicate that the SMR plant may continue to be the most favorable process choice through the 1980s or until partial oxidation or coal gasification processes are technically proven. The complexity of an efficiently designed SMR plant for production of these chemicals requires a thorough understanding of many unit operations to correctly evaluate the performance of an operating plant. Air Products and Chemicals, Inc. (APCI) owns and operates various types of SMR plants for production of hydrogen and carbon monoxide gases for pipe line sales, liquid hydrogen for merchant sale, methanol and ammonia. Over the past few years, APCI has developed guidelines and procedures for plant performance tests done at its major SMR plants. This article documents the plant test procedure used in conducting onsite SMR plant performance tests.

A process is provided for the steam reforming of normally liquid hydrocarbons to produce carbon monoxide and hydrogen, which does not promote the deposition of carbonacious materials upon catalytic surfaces. The catalyst consists of nickel promoted with the oxides of iron and manganese within a specific manganese to iron ratio, said metal and metal oxides being supported upon a refractory support. The support is preferably aluminum oxide in its alpha phase having a surface area of more than 0.5 m2/gm but no more than 10 m2/gm.

The counting of naturally occuring radiocarbon in the form of benzene in a liquid scintillation counter  

Science Journals Connector (OSTI)

A counting system is described for C14 dating with a benzene scintillator solution. The single photomultiplier counter used is relatively simple and reliable. Different sizes and forms of the counting solution containers were investigated. A 6 ml cell with a background of 4?0 counts/min and a 45 per cent detection efficiency is recommended for routine C14 dating. A 60 ml cell with a background of 14?6 counts/min and a 45 per cent detection efficiency is capable of dating samples as old as 57,500 years (4 ? statistics, 48 hr counting). The calibration and operation of the counter is discussed. On comparison with standard gas counter methods, it is suggested that routine C14 dating by the benzene method is preferable in those cases where the laboratory personnel are more skilled in chemical manipulations than electronic technique.

Thermally efficient melting and fuel reforming for glass making  

DOE Patents (OSTI)

An integrated process for utilizing waste heat from a glass making furnace. The hot off-gas from the furnace is initially partially cooled, then fed to a reformer. In the reformer, the partially cooled off-gas is further cooled against a hydrocarbon which is thus reformed into a synthesis gas, which is then fed into the glass making furnace as a fuel. The further cooled off-gas is then recycled back to absorb the heat from the hot off-gas to perform the initial cooling.

Multi-fuel reformers for fuel cells used in transportation. Multi-fuel reformers: Phase 1 -- Final report  

SciTech Connect

DOE has established the goal, through the Fuel Cells in Transportation Program, of fostering the rapid development and commercialization of fuel cells as economic competitors for the internal combustion engine. Central to this goal is a safe feasible means of supplying hydrogen of the required purity to the vehicular fuel cell system. Two basic strategies are being considered: (1) on-board fuel processing whereby alternative fuels such as methanol, ethanol or natural gas stored on the vehicle undergo reformation and subsequent processing to produce hydrogen, and (2) on-board storage of pure hydrogen provided by stationary fuel processing plants. This report analyzes fuel processor technologies, types of fuel and fuel cell options for on-board reformation. As the Phase 1 of a multi-phased program to develop a prototype multi-fuel reformer system for a fuel cell powered vehicle, the objective of this program was to evaluate the feasibility of a multi-fuel reformer concept and to select a reforming technology for further development in the Phase 2 program, with the ultimate goal of integration with a DOE-designated fuel cell and vehicle configuration. The basic reformer processes examined in this study included catalytic steam reforming (SR), non-catalytic partial oxidation (POX) and catalytic partial oxidation (also known as Autothermal Reforming, or ATR). Fuels under consideration in this study included methanol, ethanol, and natural gas. A systematic evaluation of reforming technologies, fuels, and transportation fuel cell applications was conducted for the purpose of selecting a suitable multi-fuel processor for further development and demonstration in a transportation application.

Hydrogen from Bio-Derived Liquids Hydrogen from Bio-Derived Liquids Bio-derived liquid fuels can be produced from renewable agricultural products, such as wood chips. Background Bio-derived renewable fuels are attractive for their high energy density and ease of transport. One scenario for a sustainable hydrogen economy considers that these bio-derived liquid fuels will be produced at plants close to the biomass resource, and then transported to distributed hydrogen production centers (e.g., hydrogen refueling stations), where the fuels will be reformed via the steam reforming process, similar to the current centralized production of hydrogen by the steam reforming of natural gas. Hydrogen produced by reforming these fuels must first be purified and compressed to appropriate storage and dispensing pressures. Compressing

Steam reforming of n-heptane at low concentration as a means for hydrogen injection into internal combustion engines  

SciTech Connect

Steam reforming of n-heptane at low concentration as a means for hydrogen injection into internal combustion engines, with the aim of running the engine at a lean fuel-air ratio (to reduce emissions and improve fuel economy), was studied in laboratory flow systems with both an integral and gradientless (Berty-type) fixed-bed reactor. The reaction kinetics were determined in the gradientless reactor over a Ni/Al/sub 2/O/sub 3/ catalyst at 632/sup 0/-679/sup 0/K, 1 atm total pressure, and 0.15-1.75 kPa partial pressure of n-heptane, with a recycling ratio of over 20:1. The reaction orders in hydrogen and n-heptane were 0.22 and -0.23, respectively, and the activation energy was 83.6 kj/mole. The reactant concentrations did not satisfy the equilibrium equations for the water-gas shift and methane-steam reactions at low conversions, but the agreement was good at high conversions. A small amount of benzene was produced, which decreased with increasing temperature, probably because of the polymerization, and ultimately, carbon formation.

Hydrogen plant expansion using oxygen secondary reforming  

SciTech Connect

As crude oil feedstocks become heavier and more sour, the H/sub 2/ demands of a refinery increase. Heavier sour crudes require more H/sub 2/ for hydrodesulfurization, hydrocracking and hydrotreating to produce the lighter, high quality products currently in demand. In most cases, this additional H/sub 2/ requirement is satisfied by the generation of on purpose H/sub 2/. The on purpose H/sub 2/ demand is typically satisfied by steam methane reforming (SMR). The conventional SMR process, utilizing shift, CO/sub 2/ removal, and methanation for H/sub 2/ purification, can produce 90 to 98% pure H/sub 2/ at 150 to 400 psig at an energy efficiency of 410 Btu (HHV)/SCF H/sub 2/. An SMR process employing shift and pressure swing adsorption (PSA) for H/sub 2/ purification can produce H/sub 2/ at a purity up to 99.999% and an energy efficiency of 390 Btu (HHV)/SCF H/sub 2/. Two options available for satisfying an increased on purpose H/sub 2/ demand are the addition of a new SMR plant and the debottlenecking of an existing SMR. A new SMR plant is the most capital-intensive means of expanding H/sub 2/ capacity.

THOR Bench-Scale Steam Reforming Demonstration  

SciTech Connect

The Idaho Nuclear Technology and Engineering Center (INTEC) was home to nuclear fuel reprocessing activities for decades at the Idaho National Engineering and Environmental Laboratory. As a result of the reprocessing activities, INTEC has accumulated approximately one million gallons of acidic, radioactive, sodium-bearing waste (SBW). The purpose of this demonstration was to investigate a reforming technology, offered by THORsm Treatment Technologies, LLC, for treatment of SBW into a ''road ready'' waste form that would meet the waste acceptance criteria for the Waste Isolation Pilot Plant (WIPP). A non-radioactive simulated SBW was used based on the known composition of waste tank WM-180 at INTEC. Rhenium was included as a non-radioactive surrogate for technetium. Data was collected to determine the nature and characteristics of the product, the operability of the technology, the composition of the off-gases, and the fate of key radionuclides (cesium and technetium) and volatile mercury compounds. The product contained a low fraction of elemental carbon residues in the cyclone and filter vessel catches. Mercury was quantitatively stripped from the product but cesium, rhenium (Tc surrogate), and the heavy metals were retained. Nitrates were not detected in the product and NOx destruction exceeded 98%. The demonstration was successful.

A complex chemical kinetic mechanism for the oxidation of gasoline surrogate fuels: n heptane, iso octane and toluene - Mechanism development and validation  

E-Print Network (OSTI)

The development and validation against experimental results of a new gasoline surrogate complex kinetic mechanism is presented in this paper. The surrogate fuel is a ternary mixture of n heptane, iso octane and toluene. The full three components mechanism is based on existing n heptane/iso octane (gasoline PRF) and toluene mechanisms which were modified and coupled for the purpose of this work. Mechanism results are compared against available experimental data from the literature. Simulations with the PRF plus toluene mechanism show that its behavior is in agreement with experimental results for most of the tested settings. These include a wide variety of thermodynamic conditions and fuel proportions in experimental configurations such as HCCI engine experiments, rapid compression machines, a shock tube and a jet stirred reactor.

The flash pyrolysis and methanolysis of biomass (wood) for production of ethylene, benzene and methanol  

SciTech Connect

The process chemistry of the flash pyrolysis of biomass (wood) with the reactive gases, H{sub 2} and CH{sub 4} and with the non-reactive gases He and N{sub 2} is being determined in a 1 in. downflow tubular reactor at pressures from 20 to 1000 psi and temperatures from 600 to 1000{degrees}C. With hydrogen, flash hydropyrolysis leads to high yields of methane and CO which can be used for SNG and methanol fuel production. With methane, flash methanolysis leads to high yields of ethylene, benzene and CO which can be used for the production of valuable chemical feedstocks and methanol transportation fuel. At reactor conditions of 50 psi and 1000{degrees}C and approximately 1 sec residence time, the yields based on pine wood carbon conversion are up to 25% for ethylene, 25% for benzene, and 45% for CO, indicating that over 90% of the carbon in pine is converted to valuable products. Pine wood produces higher yields of hydrocarbon products than Douglas fir wood; the yield of ethylene is 2.3 times higher with methane than with helium or nitrogen, and for pine, the ratio is 7.5 times higher. The mechanism appears to be a free radical reaction between CH{sub 4} and the pyrolyzed wood. There appears to be no net production or consumption of methane. A preliminary process design and analysis indicates a potentially economical competitive system for the production of ethylene, benzene and methanol based on the methanolysis of wood. 10 refs., 18 figs., 1 tab.

Walk the line: Conflict, state capacity and the political dynamics of reform  

Science Journals Connector (OSTI)

Abstract This paper develops a dynamic framework to analyze the political sustainability of economic reforms in developing countries. First, we demonstrate that economic reforms that are proceeding successfully may run into a political impasse, with the reform's initial success having a negative impact on its political sustainability. Second, we demonstrate that greater state capacity, to make compensatory transfers to those adversely affected by reform, need not always help the political sustainability of reform, but can also hinder it. Finally, we argue that in ethnically divided societies, economic reform may be completed not despite ethnic conflict, but because of it.

FLUIDIZED BED STEAM REFORMER MONOLITH FORMATION  

SciTech Connect

Fluidized Bed Steam Reforming (FBSR) is being considered as an alternative technology for the immobilization of a wide variety of aqueous high sodium containing radioactive wastes at various DOE facilities in the United States. The addition of clay, charcoal, and a catalyst as co-reactants converts aqueous Low Activity Wastes (LAW) to a granular or ''mineralized'' waste form while converting organic components to CO{sub 2} and steam, and nitrate/nitrite components, if any, to N{sub 2}. The waste form produced is a multiphase mineral assemblage of Na-Al-Si (NAS) feldspathoid minerals with cage-like structures that atomically bond radionuclides like Tc-99 and anions such as SO{sub 4}, I, F, and Cl. The granular product has been shown to be as durable as LAW glass. Shallow land burial requires that the mineralized waste form be able to sustain the weight of soil overburden and potential intrusion by future generations. The strength requirement necessitates binding the granular product into a monolith. FBSR mineral products were formulated into a variety of monoliths including various cements, Ceramicrete, and hydroceramics. All but one of the nine monoliths tested met the <2g/m{sup 2} durability specification for Na and Re (simulant for Tc-99) when tested using the Product Consistency Test (PCT; ASTM C1285). Of the nine monoliths tested the cements produced with 80-87 wt% FBSR product, the Ceramicrete, and the hydroceramic produced with 83.3 wt% FBSR product, met the compressive strength and durability requirements for an LAW waste form.

The use of advanced steam reforming technology for hydrogen production  

SciTech Connect

The demand for supplementary hydrogen production in refineries is growing significantly world-wide as environmental legislation concerning cleaner gasoline and diesel fuels is introduced. The main manufacturing method is by steam reforming. The process has been developed both to reduce the capital cost and increase efficiency, reliability and ease of operation. ICI Katalco`s Leading Concept Hydrogen or LCH process continues this process of improvement by replacing the conventional fired steam reformer with a type of heat exchange reformer known as the Gas Heated Reformer or GHR. The GHR was first used in the Leading Concept Ammonia process, LCA at ICI`s manufacturing site at Severnside, England and commissioned in 1988 and later in the Leading Concept Methanol (LCM) process for methanol at Melbourne, Australia and commissioned in 1994. The development of the LCH process follows on from both LCA and LCM processes. This paper describes the development and use of the GHR in steam reforming, and shows how the GHR can be used in LCH. A comparison between the LCH process and a conventional hydrogen plant is given, showing the benefits of the LCH process in certain circumstances.

Evolution of soot size distribution in premixed ethylene/air and ethylene/benzene/air flames: Experimental and modeling study  

SciTech Connect

The effect of benzene concentration in the initial fuel on the evolution of soot size distribution in ethylene/air and ethylene/benzene/air flat flames was characterized by experimental measurements and model predictions of size and number concentration within the flames. Experimentally, a scanning mobility particle sizer was used to allow spatially resolved and online measurements of particle concentration and sizes in the nanometer-size range. The model couples a detailed kinetic scheme with a discrete-sectional approach to follow the transition from gas-phase to nascent particles and their coagulation to larger soot particles. The evolution of soot size distribution (experimental and modeled) in pure ethylene and ethylene flames doped with benzene showed a typical nucleation-sized (since particles do not actually nucleate in the classical sense particle inception is often used in place of nucleation) mode close to the burner surface, and a bimodal behavior at greater height above burner (HAB). However, major features were distinguished between the data sets. The growth of nucleation and agglomeration-sized particles was faster for ethylene/benzene/air flames, evidenced by the earlier presence of bimodality in these flames. The most significant changes in size distribution were attributed to an increase in benzene concentration in the initial fuel. However, these changes were more evident for high temperature flames. In agreement with the experimental data, the model also predicted the decrease of nucleation-sized particles in the postflame region for ethylene flames doped with benzene. This behavior was associated with the decrease of soot precursors after the main oxidation zone of the flames. (author)

Steam methane reforming in molten carbonate salt. Final report  

SciTech Connect

This report documents the work accomplished on the project {open_quotes}Steam Methane Reforming in Molten Carbonate Salt.{close_quotes}. This effort has established the conceptual basis for molten carbonate-based steam reforming of methane. It has not proceeded to prototype verification, because corrosion concerns have led to reluctance on the part of large hydrogen producers to adopt the technology. Therefore the focus was shifted to a less corrosive embodiment of the same technology. After considerable development effort it was discovered that a European company (Catalysts and Chemicals Europe) was developing a similar process ({open_quotes}Regate{close_quotes}). Accordingly the focus was shifted a second time, to develop an improvement which is generic to both types of reforming. That work is still in progress, and shows substantial promise.

Pyrochlore-type catalysts for the reforming of hydrocarbon fuels  

DOE Patents (OSTI)

A method of catalytically reforming a reactant gas mixture using a pyrochlore catalyst material comprised of one or more pyrochlores having the composition A.sub.2-w-xA'.sub.wA''.sub.xB.sub.2-y-zB'.sub.yB''.sub.zO.sub.7-.DELTA.. Distribution of catalytically active metals throughout the structure at the B site creates an active and well dispersed metal locked into place in the crystal structure. This greatly reduces the metal sintering that typically occurs on supported catalysts used in reforming reactions, and reduces deactivation by sulfur and carbon. Further, oxygen mobility may also be enhanced by elemental exchange of promoters at sites in the pyrochlore. The pyrochlore catalyst material may be utilized in catalytic reforming reactions for the conversion of hydrocarbon fuels into synthesis gas (H.sub.2+CO) for fuel cells, among other uses.

Energy and exergy analysis of an ethanol reforming process for solid oxide fuel cell applications  

Science Journals Connector (OSTI)

Abstract The fuel processor in which hydrogen is produced from fuels is an important unit in a fuel cell system. The aim of this study is to apply a thermodynamic concept to identify a suitable reforming process for an ethanol-fueled solid oxide fuel cell (SOFC). Three different reforming technologies, i.e., steam reforming, partial oxidation and autothermal reforming, are considered. The first and second laws of thermodynamics are employed to determine an energy demand and to describe how efficiently the energy is supplied to the reforming process. Effect of key operating parameters on the distribution of reforming products, such as H2, CO, CO2 and CH4, and the possibility of carbon formation in different ethanol reformings are examined as a function of steam-to-ethanol ratio, oxygen-to-ethanol ratio and temperatures at atmospheric pressure. Energy and exergy analysis are performed to identify the best ethanol reforming process for SOFC applications.

Steam reforming of carbo-metallic oils  

SciTech Connect

A process is disclosed for economically converting carbo-metallic oils to liquid fuel products by bringing a converter feed containing 650/sup 0/ F. + material characterized by a carbon residue on pyrolysis of at least about 1 and by containing at least about 4 ppm of nickel equivalents of heavy metals, including nickel, into contact with a particulate cracking catalyst in a progressive flow type reactor having an elongated conversion zone. The suspension of catalyst and feed in the reactor has a vapor residence time in the range of about 0.5 to about 10 seconds, a temperature of about 900/sup 0/ F. to about 1400/sup 0/ F. and a pressure of about 10 to about 50 pounds per square inch absolute for causing a conversion per pass in the range of about 50 to about 90 percent while depositing nickel on the catalyst and coke on the catalyst in amounts in the range of about 0.3 to about 3 percent by weight. The coke-laden catalyst is separated from the resulting stream of hydrocarbons and regenerated by combustion of the coke with oxygen, the regenerated catalyst being characterized by deposited nickel in at least a partially oxidized state and a level of carbon on catalyst of about 0.25 percent by weight or less. The regenerated catalyst is contacted with a reducing gas under reducing conditions sufficient to reduce at least a portion of the oxidized nickel deposits to a reduced state and the regenerated catalyst with reduced nickel deposits is recycled to the conversion zone for contact with fresh feed. Water is also introduced into the reactor conversion zone and the amount of water and the amount of reduced nickel on the recycled catalyst are sufficient to provide a steam reforming reaction so that hydrogen deficient components of the feed are converted to products having higher hydrogen to carbon ratios and the amount of feed converted to coke is reduced. The amount of deposited nickel on catalyst is preferably in the range from about 2,000 to about 20,000 ppm.

DOE Patents (OSTI)

A heat exchanger uses the heat from processed fuel gas from a reformer for a fuel cell to superheat steam, to preheat raw fuel prior to entering the reformer and to heat a water-steam coolant mixture from the fuel cells. The processed fuel gas temperature is thus lowered to a level useful in the fuel cell reaction. The four temperature adjustments are accomplished in a single heat exchanger with only three heat transfer cores. The heat exchanger is preheated by circulating coolant and purge steam from the power section during startup of the latter.

Carbon Dioxide Reforming of Methane to Syngas by Thermal Plasma  

Science Journals Connector (OSTI)

Experiments were conducted on syngas preparation from dry reforming of methane by carbon dioxide with a DC arc plasma at atmospheric pressure. In all experiments, nitrogen gas was used as the working gas for thermal plasma to generate a high-temperature jet into a horizontal tube reactor. A mixture of methane and carbon dioxide was fed vertically into the jet. In order to obtain a higher conversion rate of methane and carbon dioxide, chemical energy efficiency and fuel production efficiency, parametric screening studies were conducted, in which the volume ratio of carbon dioxide to methane in fed gases and the total flux of fed gases were taken into account. Results showed that carbon dioxide reforming of methane to syngas by thermal plasma exhibited a larger processing capacity, higher conversion of methane and carbon dioxide and higher chemical energy efficiency and fuel production efficiency. In addition, thermodynamic simulation for the reforming process was conducted. Experimental data agreed well with the thermodynamic results, indicating that high thermal efficiency can be achieved with the thermal plasma reforming process.

Sulfur-deactivated steam reforming of gasified biomass  

SciTech Connect

The effect of hydrogen sulfide on the stream reforming of methane has been studied. Methane is the most difficult component to convert by steam reforming in the mixture of hydrocarbons, which is produced in biomass gasification. Two catalysts were subjected to hydrogen sulfide levels up to 300 ppm so as to study the effect of sulfur on their deactivation. These catalysts were the C11-9-061, from United Catalyst Inc., and the HTSR1, from Haldor Topsoee. The activation energy of the sulfur-deactivated steam-reforming reaction was calculated to be 280 and 260 kJ/mol, for each catalyst, respectively. The high values most probably originate from the fact that the degree of sulfur coverage of the nickel surface is close to 1 for these experiments. Even under these severe conditions, steam reforming of methane is possible without any carbon formation. The HTSR1 catalyst exhibits a very high sulfur-free activity, resulting in a performance in the presence of hydrogen sulfide higher than that for the C11-9-061 catalyst. By using the HTSR1 catalyst, the reactor temperature can be lowered by 60 C in order to reach comparable levels of conversion.

Static and Dynamic Simulation of Steam Methane Reformers  

Science Journals Connector (OSTI)

The steam-methane reaction is an essential step for many processing plants. Hydrogen, ammonia and methanol are mostly produced by means of methane steam reforming. Since hydrogen is essential for any refinery employing hydrotreating, the performance monitoring of the hydrogen plant is highly desirable. The use of models or simulation is now a standard practice in most chemical plants and refineries. However, reliable models are still lacking for speciality reactors like the methane steam reformer. This paper describes steady-state and dynamic models for the reactions involved in reforming methane and higher hydrocarbon gases. The performance of the reformer is then illustrated by sensitivity analysis to various input disturbances like inlet pressure, temperature, feed concentration and rate, fuel rate and density and steam to carbon ratio. The effect of these disturbances on exit temperature and conversion is studied and analyzed. Catalyst deactivation effects are also discussed and it is shown by sample calculations that the simulator can give insight into catalyst performance and assist in monitoring catalyst deactivation. The transient effects are also reported and dynamic elements like gains and response time are discussed. Such information should give insight into controller design and effects of various parameters.

The design construction, and testing of the PDU as well as performance and economic projections for a 500- lb/hr demonstration and commercial system are described. The overall system offers an environmentally safe, non-incinerating, cost-effective, and publicly acceptable method of processing LLMW. The steam-reforming technology was ranked the No. 1 non-incineration technology for destruction of hazardous organic wastes in a study commissioned by the Mixed Waste Focus Area published April 1997.1 The ThermoChem steam-reforming system has been developed over the last 13 years culminating in this successful test campaign on LLMW surrogates. Six surrogates were successfidly tested including a 750-hour test on material simulating a PCB- and Uranium- contaminated solid waste found at the Portsmouth Gaseous Diffusion Plant. The test results indicated essentially total (>99.9999oA) destruction of RCRA and TSCA hazardous halogenated organics, significant levels of volume reduction (> 400 to 1), and retention of radlonuclides in the volume-reduced solids. Cost studies have shown the steam-reforming system to be very cost competitive with more conventional and other emerging technologies.

Syngas production in a novel methane dry reformer by utilizing of tri-reforming process for energy supplying: Modeling and simulation  

Science Journals Connector (OSTI)

Abstract In this study, tri-reforming process has been utilized as an energy source for driving highly endothermic process of methane dry reforming process in a multi-tubular recuperative thermally coupled reactor (TCTDR). 184 two-concentric-tubes have been proposed for this configuration. Outer tube sides of the two-concentric-tubes have been considered for the tri-reforming reactions while dry reforming process takes place in inner tube sides. Simulation results of co-current mode have been compared with corresponding predictions of thermally coupled tri- and steam reformer (TCTSR); in which the tri-reforming process has been coupled with steam reforming of methane in same conditions. A mathematical heterogeneous model has been applied to simulate both dry and tri-reforming sides of the TCTDR. Results showed that methane conversion at the output of dry and tri-reforming sides reached to 63% and 93%, respectively. Also, molar flow rate of syngas at the output of DR side of TCTDR reached to 7464 kmol h?1 in comparison to 3912 kmol h?1 for SR side of TCTSR.

Development of Ni–Fe bimetallic based catalysts for biomass tar cracking/reforming: Effects of catalyst support and co-fed reactants on tar conversion characteristics  

Science Journals Connector (OSTI)

Abstract Catalytic activities of Ni- and Ni–Fe bimetallic based catalysts supported by palygorskite, MgO–Al2O3, La0.8Ca0.2CrO3, and La0.8Ca0.2CrO3/MgO–Al2O3 toward the cracking and reforming of naphthalene and toluene (as biomass tar model compounds) as well as real biomass tar from pyrolysis of eucalyptus wood chips were studied. At 700-900 °C, the main products from the cracking of these hydrocarbons are H2, CH4, C2H4, C2H6, and C3H6. Among all catalysts, Ni–Fe supported by MgO–Al2O3 and La0.8Ca0.2CrO3/MgO–Al2O3 show the highest H2 yield values and good resistance toward carbon deposition. Additions of H2O and CO2 can promote steam and dry reforming, from which H2 and CO were the major products from the reaction and the amount of carbon formation was considerably reduced. Importantly, the H2O/tar and CO2/tar ratios strongly affect the H2 yield value, particularly for Ni–Fe/La0.8Ca0.2CrO3/MgO–Al2O3 due to the presence of perovskite-based La0.8Ca0.2CrO3. At proper H2O/tar and CO2/tar ratios, La0.8Ca0.2CrO3 behaves like the partly-reduced metal-oxide catalysts and promotes the reforming activity. Addition of O2 along with H2O and/or CO2 can further reduce the carbon formation and increase the H2 yield. Nevertheless, excess O2 could oxidize metal particles and combusted H2 to H2O, which causes lower H2 yield production.

Effect of Key Parameters on the Photocatalytic Oxidation of Toluene at Low Concentrations in Air under 254 + 185 nm UV Irradiation  

SciTech Connect

The effect of key experimental parameters on the removal of toluene under 254 + 185 nm irradiation was investigated using a benchtop photocatalytic flow reactor. Toluenewas introduced at low concentrations between 10 and 500 ppbv, typical of indoorenvironments, and reacted on TiO2-coated Raschig rings. Two different TiO2-coated rings were prepared: in one case, by dip-coating using a P25 aqueous suspension and, on the other, using an organic/inorganic sol-gel method that produced thin films of mesoporous anatase. Flow rates in the photoreactor varied between 4 L min-1 and 125 mL min-1, leading to residence times in the range 100 ms< tau< 2 s. For these conditions, toluene removal efficiencies were between 30 and 90percent, indicating that the system did not achieve total conversion in any case. For each air flow rate, the conversion oftoluene was significantly higher when the reactor length was 10 cm, as compared with 5 cm; however, only marginal increases in conversions were achieved in the two reactor lengths at equal residence time and different concentration of toluene, suggesting that that the reactor is effectively behaving as an ideal reactor and that the reaction is first-order in the concentration of toluene. Experiments were carried out between 0 and 66percent relative humidity (RH), the fastest reaction rate being observed at moderately low humidity conditions (10percent RH), with respect to both dry air and higher humidity levels. Formaldehyde was formed as a partial oxidation byproduct at low and at high residence times (240 and 960 ms), although higher formaldehyde molar yields (up to 20percent) were observed at low tau (240 ms) and moderate humidity conditions (10 and 33percent), suggesting that both tau and RH can be optimized toreduce the formation of harmful intermediates. Toluene removal efficiency increased with the TiO2 thickness (i.e., mass) until a maximum value of 500 nm, beyond which the removal efficiency decreased. This should be attributed to limitations on the rates of toluene decomposition imposed by radiation transport through the film and/or internal diffusion resistances, which can take place within the porous photocatalytic films.

Reforming petroleum-based fuels for fuel cell vehicles : composition-performance relationships.  

SciTech Connect

Onboard reforming of petroleum-based fuels, such as gasoline, may help ease the introduction of fuel cell vehicles to the marketplace. Although gasoline can be reformed, it is optimized to meet the demands of ICEs. This optimization includes blending to increase the octane number and addition of oxygenates and detergents to control emissions. The requirements for a fuel for onboard reforming to hydrogen are quite different than those for combustion. Factors such as octane number and flame speed are not important; however, factors such as hydrogen density, catalyst-fuel interactions, and possible catalyst poisoning become paramount. In order to identify what factors are important in a hydrocarbon fuel for reforming to hydrogen and what factors are detrimental, we have begun a program to test various components of gasoline and blends of components under autothermal reforming conditions. The results indicate that fuel composition can have a large effect on reforming behavior. Components which may be beneficial for ICEs for their octane enhancing value were detrimental to reforming. Fuels with high aromatic and naphthenic content were more difficult to reform. Aromatics were also found to have an impact on the kinetics for reforming of paraffins. The effects of sulfur impurities were dependent on the catalyst. Sulfur was detrimental for Ni, Co, and Ru catalysts. Sulfur was beneficial for reforming with Pt catalysts, however, the effect was dependent on the sulfur concentration.

Long term savings decisions: Financial reform, peer effects and ethnicity  

Science Journals Connector (OSTI)

Abstract In 2005, a drastic reform in the Israeli capital market shifted the power to choose savings vehicles from employers to individuals. Using a unique dataset from a large employer, this event provides us a rare window into individuals’ savings decisions and the effect of their social environment. In the first year following the reform's implementation, 7% of the employees switched out of the fund in which they all previously saved. Choice of fund was not associated with observable measures of fund performance, but was strongly affected by the employees’ social environment. Exploiting within-department variation in peer groups, we find that savings decisions were strongly influenced by the choices of co-workers from the same ethnic group. Interviews also point to the influence of non-professional colleagues.

Addiction treatment centers' progress in preparing for health care reform  

Science Journals Connector (OSTI)

Abstract The Patient Protection and Affordable Care Act (PPACA) is expected to significantly alter addiction treatment service delivery. Researchers designed the Health Reform Readiness Index (HRRI) for addiction treatment organizations to assess their readiness for the PPACA. Four-hundred twenty-seven organizations completed the HRRI throughout a 3-year period, using a four-point scale to rank their readiness on 13 conditions. HRRI results completed during two different time periods (between 10/1/2010–6/30/2011 and 9/1/2011–9/30/2012) were analyzed and compared. Most respondents self-assessed as being in the early stages of preparation for 9 of the 13 conditions. Survey results showed that organizations with annual budgets  $5 million (n = 132). The HRRI results suggest that the addiction field, and in particular smaller organizations, is not preparing adequately for health care reform; organizations that are making preparations are making only modest gains.

In situ Gas Conditioning in Fuel Reforming for Hydrogen Generation  

SciTech Connect

The production of hydrogen for fuel cell applications requires cost and energy efficient technologies. The Absorption Enhanced Reforming (AER), developed at ZSW with industrial partners, is aimed to simplify the process by using a high temperature in situ CO2 absorption. The in situ CO2 removal results in shifting the steam reforming reaction equilibrium towards increased hydrogen concentration (up to 95 vol%). The key part of the process is the high temperature CO2 absorbent. In this contribution results of Thermal Gravimetric Analysis (TGA) investigations on natural minerals, dolomites, silicates and synthetic absorbent materials in regard of their CO2 absorption capacity and absorption/desorption cyclic stability are presented and discussed. It has been found that the inert parts of the absorbent materials have a structure stabilizing effect, leading to an improved cyclic stability of the materials.

Modelling, simulation and sensitivity analysis of steam-methane reformers  

Science Journals Connector (OSTI)

A mathematical model to calculate temperature, conversion and pressure profiles for static operations in steam-methane reformers was simulated. A rigorous kinetic model describing steam-methane reactions was compared to a first order one and an empirical heat distribution model was fitted to describe heat absorbed along the reactor length. A control interface was simulated to allow sensitivity analysis with different control schemes. The kinetic models were tested with data from industrial steam-gas reformers. Simulation results agreed with actual plant data for conversion, temperature and pressure. Nevertheless, the first order kinetic model gave unrealistic sensitivity results to pressure and steam-to-carbon ratio variations. The rigorous model could confidently be used for design analysis, control, and economic evaluation purposes.

Graphical abstract: Reaction of a SeCl{sub 4} aqueous solution with a NiCl{sub 2}·6H{sub 2}O aqueous solution in presence of sodium dodecyl benzene sulfonate (SDBS) as capping agent and hydrazine (N{sub 2}H{sub 4}·H{sub 2}O) as reductant, produces nanosized nickel selenide through a hydrothermal method. The effect of temperature, reaction time and amounts of reductant on the morphology, particle sizes of NiSe nanostructures has been investigated. Highlights: ? NiSe nanostructures were synthesized by hydrothermal method. ? A novel Se source was used to synthesize NiSe. ? SDBS as capping agent plays a crucial role on the morphology of products. ? A mixture of Ni{sub 3}Se{sub 2} and NiSe was prepared in the presence of 2 ml hydrazine. ? A pure phase of NiSe was prepared in the presence of 4 or 6 ml hydrazine. -- Abstract: The effects of the anionic surfactant on the morphology, size and crystallization of NiSe precipitated from NiCl{sub 2}·6H{sub 2}O and SeCl{sub 4} in presence of hydrazine (N{sub 2}H{sub 4}·H{sub 2}O) as reductant were investigated. The products have been successfully synthesized in presence of sodium dodecyl benzene sulfonate (SDBS) as surfactant via an improved hydrothermal route. A variety of synthesis parameters, such as reaction time and temperature, capping agent and amount of reducing agent have a significant effect on the particle size, phase purity and morphology of the obtained products. The sample size became bigger with decreasing reaction temperature and increasing reaction time. In the presence of 2 ml hydrazine, the samples were found to be the mixture of Ni{sub 3}Se{sub 2} and NiSe. With increasing the reaction time and amount of hydrazine a pure phase of hexagonal NiSe was obtained. X-ray diffraction analysis (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM) images indicate phase, particle size and morphology of the products. Chemical composition and purity of the products were characterized by X-ray energy dispersive spectroscopy (EDS). Photoluminescence (PL) was used to study the optical properties of NiSe samples.

Payment reform and changes in health care in China  

Science Journals Connector (OSTI)

Abstract This paper is intended to assess the primary effects on cost, utilization and quality of care from payment reform of capitation and open enrollment in Changde city, Hunan Province of China. Open enrollment policy was introduced to deal with possible cream skimming associated with capitation. Based on the longitudinal Urban Resident Basic Medical Insurance (URBMI) Household Survey, this study analyses the URBMI data through a set of regression models. The original data included over five thousand inpatient admissions during the study period between 2008 and 2010. The study finds the payment reform to reduce its inpatient out-of-pocket cost by 19.7%, out-of-pocket ratio by 9.5%, and length of stay by 17.7%. However, the total inpatient cost, drug cost ratio, treatment effect, and patient satisfaction showed little difference between Fee-For-Service and capitation models. We conclude that the payment reform in Changde did not reduce overall inpatient expenditure, but it decreased the financial risk and length of stay of inpatient patients without compromising quality of care. The findings would contribute to the health care payment literatures from developing countries and open further research tracks on the ability of open enrollment to compensate for capitation drawbacks.

Steam reforming of low-level mixed waste. Final report  

SciTech Connect

ThermoChem has successfully designed, fabricated and operated a nominal 90 pound per hour Process Development Unit (PDU) on various low-level mixed waste surrogates. The design, construction, and testing of the PDU as well as performance and economic projections for a 300-lb/hr demonstration and commercial system are described. The overall system offers an environmentally safe, non-incinerating, cost-effective, and publicly acceptable method of processing LLMW. The steam-reforming technology was ranked the No. 1 non-incineration technology for destruction of hazardous organic wastes in a study commissioned by the Mixed Waste Focus Area and published in April 1997. The ThermoChem steam-reforming system has been developed over the last 13 years culminating in this successful test campaign on LLMW surrogates. Six surrogates were successfully tested including a 750-hour test on material simulating a PCB- and Uranium-contaminated solid waste found at the Portsmouth Gaseous Diffusion Plant. The test results indicated essentially total (> 99.9999%) destruction of RCRA and TSCA hazardous halogenated organics, significant levels of volume reduction (> 400 to 1), and retention of radionuclides in the volume-reduced solids. Economic evaluations have shown the steam-reforming system to be very cost competitive with more conventional and other emerging technologies.

A Complete Basis Set Estimate of Cation-p Bond Strengths: Na+(ethylene) and Na+(benzene)  

SciTech Connect

Large scale second order perturbation theory and couple cluster theory calculations were performed on the Na+(ethylene) and Na+(benzene) complexes in an effort to estimate binding enthalpies in the complete basis set limit. The resulting best estimates are DH0[Na+(ethylene)] = -13.7 ? 0.2 kcal/mol and DH0[Na+(benzene)] = -23.9 ? 0.3 kcal/mol, which include small corrections for core/valence correlation effects. The former value can be compared to a measurement of -10.3 ? 1.0 kcal/mol obtained from collision induced dissociation, while the latter value is approximately midway between the two existing experimental values which differed by 6.5 kcal/mol. For the basis sets considered in this study, the counterpoise-corrected binding energies were found to be in much worse agreement with the complete basis set limit than the raw values.

Hydrogen Production by Catalytic Steam Reforming of Bio-oil, Naphtha  

Science Journals Connector (OSTI)

Hydrogen production by catalytic steam reforming of the bio-oil, naphtha, and CH4 was investigated over a novel metal-doped catalyst of (Ca24Al28O64)4+4O?/Mg (C12A7-Mg). The catalytic steam reforming was investigated from 250 to 850°C in the fixed-bed continuous flow reactor. For the reforming of bio-oil, the yield of hydrogen of 80% was obtained at 750°C, and the maximum carbon conversion is nearly close to 95% under the optimum steam reforming condition. For the reforming of naphtha and CH4, the hydrogen yield and carbon conversion are lower than that of bio-oil at the same temperature. The characteristics of catalyst were also investigated by XPS. The catalyst deactivation was mainly caused by the deposition of carbon in the catalytic steam reforming process.

Reformer-pressure swing adsorption process for the production of carbon monoxide  

SciTech Connect

An improved process for the production of carbon monoxide by the steam reforming of hydrocarbons is described comprising: (a) catalytically reacting a fluid hydrocarbon feed stream with steam in a steam reformer; (b) passing the reformer effluent containing hydrogen, carbon monoxide and carbon dioxide from the steam reformer, without scrubbing to remove the carbon dioxide content thereof, to a pressure swing adsorption system having at least four adsorbent beds, each bed of which, on a cyclic basis, undergoes a processing sequence; (c) recycling the carbon dioxide-rich stream to the steam reformer for reaction with additional quantities of the hydrocarbon feed stream being passed to the stream reformer to form additional quantities of carbon monoxide and hydrogen, with product recovery being enhanced and the need for employing a carbon dioxide wash system being obviated.

Thorium ions transport across Tri-n-butyl phosphate-benzene based supported liquid membranes  

SciTech Connect

Transport of Th(IV) ions across tri-n-butyl phosphate (TBP) benzene based liquid membranes supported in microporous hydrophobic polypropylene film (MHPF) has been studied. Various parameters such as variation of nitric acid concentration in the feed, TBP concentration in the membrane, and temperature on the given metal ions transport have been investigated. The effects of nitric acid and TBP concentrations on the distribution coefficient were also studied, and the data obtained were used to determine the Th ions-TBP complex diffusion coefficient in the membrane. Permeability coefficients of Th(IV) ions were also determined as a function of the TBP and nitric acid concentrations. The optimal conditions for the transport of Th(IV) ions across the membrane are 6 mol{sm_bullet}dm{sup -3} HNO{sub 3} concentration, 2.188 mol {center_dot} dm{sup -3} TBP concentration, and 25{degrees}C. The stoichiometry of the chemical species involved in chemical reaction during the transport of Th(IV) ions has also been studied.

Columbia River Hatchery Reform System-Wide Report.  

SciTech Connect

The US Congress funded the Puget Sound and Coastal Washington Hatchery Reform Project via annual appropriations to the US Fish and Wildlife Service (USFWS) beginning in fiscal year 2000. Congress established the project because it recognized that while hatcheries have a necessary role to play in meeting harvest and conservation goals for Pacific Northwest salmonids, the hatchery system was in need of comprehensive reform. Most hatcheries were producing fish for harvest primarily to mitigate for past habitat loss (rather than for conservation of at-risk populations) and were not taking into account the effects of their programs on naturally spawning populations. With numerous species listed as threatened or endangered under the Endangered Species Act (ESA), conservation of salmon in the Puget Sound area was a high priority. Genetic resources in the region were at risk and many hatchery programs as currently operated were contributing to those risks. Central to the project was the creation of a nine-member independent scientific review panel called the Hatchery Scientific Review Group (HSRG). The HSRG was charged by Congress with reviewing all state, tribal and federal hatchery programs in Puget Sound and Coastal Washington as part of a comprehensive hatchery reform effort to: conserve indigenous salmonid genetic resources; assist with the recovery of naturally spawning salmonid populations; provide sustainable fisheries; and improve the quality and cost-effectiveness of hatchery programs. The HSRG worked closely with the state, tribal and federal managers of the hatchery system, with facilitation provided by the non-profit organization Long Live the Kings and the law firm Gordon, Thomas, Honeywell, to successfully complete reviews of over 200 hatchery programs at more than 100 hatcheries across western Washington. That phase of the project culminated in 2004 with the publication of reports containing the HSRG's principles for hatchery reform and recommendations for Puget Sound/Coastal Washington hatchery programs, followed by the development in 2005 of a suite of analytical tools to support application of the principles (all reports and tools are available at www.hatcheryreform.us). In 2005, Congress directed the National Oceanic and Atmospheric Administration-Fisheries (NOAA Fisheries) to replicate the Puget Sound and Coastal Washington Hatchery Reform Project in the Columbia River Basin. The HSRG was expanded to 14 members to include individuals with specific knowledge about the Columbia River salmon and steelhead populations. This second phase was initially envisioned as a one-year review, with emphasis on the Lower Columbia River hatchery programs. It became clear however, that the Columbia River Basin needed to be viewed as an inter-connected ecosystem in order for the review to be useful. The project scope was subsequently expanded to include the entire Basin, with funding for a second year provided by the Bonneville Power Administration (BPA) under the auspices of the Northwest Power and Conservation Council's (NPCC) Fish and Wildlife Program. The objective of the HSRG's Columbia River Basin review was to change the focus of the Columbia River hatchery system. In the past, these hatchery programs have been aimed at supplying adequate numbers of fish for harvest as mitigation primarily for hydropower development in the Basin. A new, ecosystem-based approach is founded on the idea that harvest goals are sustainable only if they are compatible with conservation goals. The challenge before the HSRG was to determine whether or not conservation and harvest goals could be met by fishery managers and, if so, how. The HSRG determined that in order to address these twin goals, both hatchery and harvest reforms are necessary. The HSRG approach represents an important change of direction in managing hatcheries in the region. It provides a clear demonstration that current hatchery programs can indeed be redirected to better meet both conservation and harvest goals.

SMALL SCALE FUEL CELL AND REFORMER SYSTEMS FOR REMOTE POWER  

SciTech Connect

New developments in fuel cell technologies offer the promise of clean, reliable affordable power, resulting in reduced environmental impacts and reduced dependence on foreign oil. These developments are of particular interest to the people of Alaska, where many residents live in remote villages, with no roads or electrical grids and a very high cost of energy, where small residential power systems could replace diesel generators. Fuel cells require hydrogen for efficient electrical production, however. Hydrogen purchased through conventional compressed gas suppliers is very expensive and not a viable option for use in remote villages, so hydrogen production is a critical piece of making fuel cells work in these areas. While some have proposed generating hydrogen from renewable resources such as wind, this does not appear to be an economically viable alternative at this time. Hydrogen can also be produced from hydrocarbon feed stocks, in a process known as reforming. This program is interested in testing and evaluating currently available reformers using transportable fuels: methanol, propane, gasoline, and diesel fuels. Of these, diesel fuels are of most interest, since the existing energy infrastructure of rural Alaska is based primarily on diesel fuels, but this is also the most difficult fuel to reform, due to the propensity for coke formation, due to both the high vaporization temperature and to the high sulfur content in these fuels. There are several competing fuel cell technologies being developed in industry today. Prior work at UAF focused on the use of PEM fuel cells and diesel reformers, with significant barriers identified to their use for power in remote areas, including stack lifetime, system efficiency, and cost. Solid Oxide Fuel Cells have demonstrated better stack lifetime and efficiency in demonstrations elsewhere (though cost still remains an issue), and procuring a system for testing was pursued. The primary function of UAF in the fuel cell industry is in the role of third party independent testing. In order for tests to be conducted, hardware must be purchased and delivered. The fuel cell industry is still in a pre-commercial state, however. Commercial products are defined as having a fixed set of specifications, fixed price, fixed delivery date, and a warrantee. Negotiations with fuel cell companies over these issues are often complex, and the results of these discussions often reveal much about the state of development of the technology. This work includes some of the results of these procurement experiments. Fuel cells may one day replace heat engines as the source of electrical power in remote areas. However, the results of this program to date indicate that currently available hardware is not developed sufficiently for these environments, and that significant time and resources will need to be committed for this to occur.

Electron-induced dry reforming of methane in a temperature-controlled dielectric barrier discharge reactor  

Science Journals Connector (OSTI)

Dry reforming of methane has the potential to reduce the greenhouse gases methane and carbon dioxide and to generate hydrogen-rich syngas. In reforming methane, plasma-assisted reforming processes may have advantages over catalytic processes because they are free from coking and their response time for mobile applications is quick. Although plasma-assisted reforming techniques have seen recent developments, systematic studies that clarify the roles that electron-induced chemistry and thermo-chemistry play are needed for a full understanding of the mechanisms of plasma-assisted reformation. Here, we developed a temperature-controlled coaxial dielectric barrier discharge (DBD) apparatus to investigate the relative importance of electron-induced chemistry and thermo-chemistry in dry reforming of methane. In the tested background temperature range 297–773 K, electron-induced chemistry, as characterized by the physical properties of micro-discharges, was found to govern the conversions of CH4 and CO2, while thermo-chemistry influenced the product selectivities because they were found to depend on the background temperature. Comparisons with results from arc-jet reformation indicated that thermo-chemistry is an efficient conversion method. Our findings may improve designs of plasma-assisted reformers by using relatively hotter plasma sources. However, detailed chemical kinetic studies are needed.

Fiftieth CCR reformer goes on stream in Germany  

SciTech Connect

The fiftieth continuous catalytic reformer built since this technology was introduced by UOP Process Division in 1971 has gone on stream in West Germany. The 21,300-b/sd unit is in Deutsche Shell AG's Godorf refinery. It is the sixth such unit put in service by Shell International. Others are in refineries at Harburg, West Germany; Shellhaven, England; Palau Bokum, Singapore; Pernis, Netherlands; and Geelong, Australia. CCR units operate at much higher severity than older reforming units. Severity is a function of higher octane, lower pressure, and feedstock. The operating severity or catalyst deactivation rate may be 20 times that of high pressure, low octane units. Continuous catalyst regeneration is then the key for maintaining long-term operations at steady state conditions. To facilitate continuous catalyst regeneration, the three reactors are stacked. This design permits the catalyst to move in essentially plug flow through the reactors at a rate determined by the rate of catalyst withdrawal to the regeneration section.

Modified Ni-Cu catalysts for ethanol steam reforming  

SciTech Connect

Three Ni-Cu catalysts, having different Cu content, supported on ?-alumina were synthesized by wet co-impregnation method, characterized and tested in the ethanol steam reforming (ESR) reaction. The catalysts were characterized for determination of: total surface area and porosity (N{sub 2} adsorption - desorption using BET and Dollimer Heal methods), Ni surface area (hydrogen chemisorption), crystallinity and Ni crystallites size (X-Ray Diffraction), type of catalytic active centers (Hydrogen Temperature Programmed Reduction). Total surface area and Ni crystallites size are not significantly influenced by the addition of Cu, while Ni surface area is drastically diminished by increasing of Cu concentration. Steam reforming experiments were performed at atmospheric pressure, temperature range 150-350°C, and ethanol - water molar ration of 1 at 30, using Ar as carrier gas. Ethanol conversion and hydrogen production increase by the addition of Cu. At 350°C there is a direct connection between hydrogen production and Cu concentration. Catalysts deactivation in 24h time on stream was studied by Transmission Electron Microscopy (TEM) and temperature-programmed reduction (TPR) on used catalysts. Coke deposition was observed at all studied temperatures; at 150°C amorphous carbon was evidenced, while at 350°C crystalline, filamentous carbon is formed.

Hydrogen production in Multi-Channel Membrane Reactor via Steam Methane Reforming and Methane Catalytic Combustion  

Science Journals Connector (OSTI)

Abstract A novel Multi-Channel Membrane Reactor (MCMR) was designed and built for the small-scale production of hydrogen via Steam Methane Reforming (SMR). The prototype alternates an SMR gas channel to produce hydrogen catalytically, with a Methane Catalytic Combustion (MCC) gas channel to provide the heat of reaction needed by the endothermic reforming. A palladium–silver membrane inside the reforming gas channel shifts the reaction equilibrium, allowing lower operating temperatures, and producing pure hydrogen in a single vessel. Using an innovative air-spray coating technique, channels were coated with Ru–MgO–La2O3/?-Al2O3 and Pd/?-Al2O3 catalyst particles for the SMR and MCC reactions, respectively. Results for the proof-of-concept MCMR showed that methane conversion in the reformer of 91% and a hydrogen purity in excess of 99.99% were possible with the reformer operating at 570 °C and 15 bar.

Forging growth by governing the market in reform-era urban China  

Science Journals Connector (OSTI)

Abstract China’s accelerating urban growth over the past decade has been examined from the perspectives of state devolution or place-making initiatives. Relatively little has been written to contextualize the burgeoning urbanism in China’s reform and the resultant changing relationship between state and market. Through an investigation of fiscal and land use reforms since the mid-1990s, this paper argues that China’s gradual and partial reform has fundamentally re-engineered local states from inward-looking market actors running business to entrepreneurial market governors controlling land supply. Though this transition has triggered urban growth by levering manufacturing and real estate capital, it has also introduced constraints for future urban development by generating inter-regional tensions and making further reforms politically difficult. This paper concludes that sustainable urbanism requires a more clearly oriented and more holistic reform framework.

Activity and structure of perovskites as diesel reforming catalysts for solid oxide fuel cells.  

SciTech Connect

Recent progress in developing perovskite materials as more cost-effective catalysts in autothermal reforming (ATR) of diesel fuel to hydrogen-rich reformate for solid oxide fuel cell (SOFC) application is reported. Perovskite-type metal oxides with B sites partially exchanged by ruthenium were prepared and evaluated under ATR reaction conditions. The hydrogen yield, reforming efficiency, and CO{sub x} selectivity of these catalysts were investigated using diesel surrogate fuel with 50 ppm sulfur. The catalyst performances have approached or exceeded a benchmark, high-cost rhodium-based material. In parallel with the reactivity study, we also investigated the physical properties of B-site doped perovskites and their impact on the reforming performance using various characterization techniques such as BET, X-ray powder diffraction, temperature programmable reduction, scanning electron microscopy, and synchrotron X-ray absorption spectroscopy. We found that ruthenium is highly dispersed into perovskite lattice and its redox behavior is directly associated with reforming activity.

Steam reforming of methane using double-walled reformer tubes containing high-temperature thermal storage Na2CO3/MgO composites for solar fuel production  

Science Journals Connector (OSTI)

Abstract Double-walled reactor tubes containing thermal storage materials based on the molten carbonate salts—100 wt% Na2CO3 molten salt, 90 wt% Na2CO3/10 wt% MgO and 80 wt% Na2CO3/20 wt% MgO composite materials—were studied for the performances of the reactor during the heat charging mode, while those of methane reforming with steam during heat discharging mode for solar steam reforming. The variations in the temperatures of the catalyst and storage material, methane conversion, duration of reforming for obtaining high levels of methane conversion (>90%), higher heating value (HHV) power of reformed gas and efficiency of the reactor tubes were evaluated for the double-walled reactor tubes and a single-wall reactor tube without the thermal storage. The results for the heat charging mode indicated that the composite thermal storage could successfully store the heat transferred from the exterior wall of the reactor in comparison to the pure molten-salt. The double-walled reactor tubes with the 90 wt% Na2CO3/10 wt% MgO composite material was the most desirable for steam reforming of methane to realize large HHV amounts of reformed gas and higher efficiencies during heat-discharging mode.

Ultraviolet photoelectron spectroscopic study of the interaction of potassium with carbon monoxide and benzene on the Pt(111) surface  

SciTech Connect

The interaction of potassium with carbon monoxide and benezene has been studied on the Pt(111) crystal surface by ultraviolet photoelectron spectroscopy (UPS). The adsorptive changes reported in previous studies for carbon monoxide and benzene when potassium is coadsorbed are correlated with the UPS results presented here and are explained with the aid of a molecular orbital analysis. The authors find that the valence molecular orbitals increase their binding energy slightly when the potassium is coadsorbed, implying a model in which the adsorbates sense the potassium-induced changes in dipole field at the surface. 36 references, 11 figures.

Impact of the revised OSHA exposure standard on evaluation and control of benzene and other volatile organic chemicals in the liquid petroleum pipeline industry  

SciTech Connect

The primary purpose of this study was to determine the benzene exposure potential of workers in the liquid petroleum pipeline industry and to assess the impact of compliance with the revised standard on this industry. In addition, exposure to ethylene dibromide (EDB), and ethylene dichloride (EDC), which have toxicological profiles similar to that of benzene and are routinely found in this industry, were evaluated and appropriate control protocols were recommended. Exposure potential to benzene in excess of the 0.5 ppm (8-hour TWA) OSHA action level was shown to be limited to three free product handling operations, and that this increased exposure potential was dependent on the length of time necessary to perform the operations. The incidence and magnitude of benzene overexposure was not severe and control could be accomplished with engineering methods, along with work practice controls and personal protective equipment. Through application of a risk assessment model it was shown that 14 excess leukemia deaths per one thousand workers could be expected in the employee population that routinely performs those operation having maximum benzene exposure potential. This compares to less than on excess leukemia death per one thousand workers in the total work population. The evaluation of EDB and EDC indicated that exposure potential to EDB was of greatest concern. Even though exposure could be limited through application of standard industrial hygiene methods, any control protocol short of total elimination of EDB from the product stream may be not sufficient to reduce exposure to accepted levels.

Surface structure of coadsorbed benzene and carbon monoxide on the rhodium(111) single crystal analyzed with low-energy electron diffraction intensities  

SciTech Connect

The first structural analysis of a molecular coadsorbate system is presented. Mutual reordering and site shifting are found to occur for benzene and CO coadsorbed in a (/sub 13//sup 31/) lattice on Rh(111). This low-energy electron diffraction (LEED) intensity analysis yields the first confirmed hollow-site adsorption of CO on a single-crystal metal surface, with a C-O bond length expanded by 0.06 +/- 0.05 A from the gas phase. The flat-lying benzene is found centered over hcp-type hollow sites with a strong Kekule-type distortion: C-C bond lengths alternate between 1.33 +/- 0.15 A (hydrogen positions were not determined). This suggests the possibility of a 1,3,5-cyclohexatriene species being formed. The Rh-C bond length is 2.35 +/- 0.05 A for benzene and 2.16 +/- 0.04 A for CO.

Facile preparation of sphere-like copper ferrite nanostructures and their enhanced visible-light-induced photocatalytic conversion of benzene  

SciTech Connect

Graphical abstract: - Highlights: • Spinel CuFe{sub 2}O{sub 4} nanospheres were successfully synthesized via a facile method. • CuFe{sub 2}O{sub 4} nanospheres showed high photocatalytic activity toward benzene. • Ethyl acetate, carboxylic acid and aldehyde were the intermediate products. - Abstract: Spinel copper ferrite nanospheres with diameters of about 116 nm were synthesized in high yield via a facile solvothermal route. The prepared nanospheres had cubic spinel structure and exhibited good size uniformity and regularity. The band-gap energy of CuFe{sub 2}O{sub 4} nanospheres was calculated to be about 1.69 eV, indicating their potential visible-light-induced photocatalytic activity. The dramatically enhanced photocatalytic activity of the CuFe{sub 2}O{sub 4} nanospheres was evaluated via the photocatalytic conversion of benzene under Xe lamp irradiation. By using the in situ FTIR technique, ethyl acetate, carboxylic acid and aldehyde could be regarded as the intermediate products, and CO{sub 2} was produced as the final product during the reaction process. This study provided new insight into the design and preparation of functional nanomaterials with sphere structure in high yield, and the as-grown architectures demonstrated an excellent ability to remove organic pollutants in the atmosphere.

The Internal Molecular Potential Between the Substituent Groups in a Benzene Ring as Derived from the Heats of Combustion  

Science Journals Connector (OSTI)

It is shown that differences in the observed heats of combustion of isomeric benzene derivatives can be interpreted as the internal molecular potential existing between their substituent groups. A like interpretation can be given for the differences between the values observed for the heats of combustion of certain nonisomeric benzene derivatives and those calculated by the rule of additivity. This internal potential, to which the attractive and repulsive forces between the groups are due, results from the electrostatic potential of the group moments (dipole effect), the polarization of the substituents and of the ring (induction effect), the dispersion effect, and from steric hindrance. We have, therefore, a new and direct method of measuring the internal potential, which determines both the internal motion of groups within an organic molecule and its most stable configuration. The values thus measured are in good agreement with values theoretically evaluated from the above intermolecular (van der Waals) forces. From the data derived by this method we conclude in the case of o-xylene that valence angles of 120° between the C—CH3 bond and the aromatic C—C bonds are extremely stable, for the energy required to distort these angles through 10° is greater than 2 K cal/mole. We find, also, very restricted rotation for the butane molecule, from which it follows that saturated aliphatic hydrocarbons in the gaseous state tend to form zigzag chains. Such restricted rotation is found for the ether molecule as well.

Has Massachusetts health care reform worked for the working poor? Results from an analysis of opportunity  

Science Journals Connector (OSTI)

AbstractPurpose Health care reform was introduced in Massachusetts (MA) in 2006 and serves as a model for what was subsequently introduced nationally as the Patient Protection and Affordable Care Act. The Boston Area Community Health survey collected data before (2002–2005) and after (2006–2010) introduction of the MA health insurance mandate, providing a unique opportunity to assess its effects in a large, epidemiologic cohort. Methods We report on the apparent effects of the mandate on the same participants over time, focusing specifically on the vulnerable working poor (WP). We evaluated differences in subpopulations of interest at pre- and post-reform periods to explore whether MA health care reform resulted in an overall gain in insurance coverage. Results MA health care reform was associated with net gains in health insurance coverage overall and among the subgroups studied. Our findings suggest that despite being targeted by health care reform legislation, the WP in MA continue to report lower rates of insurance coverage compared with both the nonworking poor and the not poor. Conclusions MA health care reform legislation, including the expansion of Medicaid, resulted in substantial overall gains in coverage. Disparities in insurance coverage persist among some subgroups following health care reform implementation in MA. These results have important implications for health services researchers and policy makers, particularly in light of the ongoing implementation of the Patient Protection and Affordable Care Act.

Vehicle type choice under the influence of a tax reform and rising fuel prices  

Science Journals Connector (OSTI)

Abstract Differentiated vehicle taxes are considered by many a useful tool for promoting environmentally friendly vehicles. Various structures have been implemented in several countries, e.g. Ireland, France, The Czech Republic, and Denmark. In many countries the tax reforms have been followed by a steep change in new vehicle purchases toward more diesel vehicles and more fuel-efficient vehicles. The paper analyses to what extent a vehicle tax reform similar to the Danish 2007 reform may explain changes in purchasing behaviour. The paper investigates the effects of a tax reform, fuel price changes, and technological development on vehicle type choice using a mixed logit model. The model allows a simulation of the effect of car price changes that resemble those induced by the tax reform. This effect is compared to the effects of fuel price changes and technology improvements. The simulations show that the effect of the tax reform on fuel efficiency is similar to the effect of rising fuel prices while the effect of technological development is much larger. The conclusion is that while the tax reform appeared in the same year as a large increase in fuel efficiency, it seems likely that it only explains a small part of the shift in fuel efficiency that occurred and that the main driver was the technological development.

In silico search for novel methane steam reforming catalysts  

Science Journals Connector (OSTI)

This paper demonstrates a method for screening transition metal and metal alloy catalysts based on their predicted rates and stabilities for a given catalytic reaction. This method involves combining reaction and activation energies (available to the public via a web-based application 'CatApp') with a microkinetic modeling technique to predict the rates and selectivities of a prospective material. This paper illustrates this screening technique using the steam reforming of methane to carbon monoxide and hydrogen as a test reaction. While catalysts are already commercially available for this process, the method demonstrated in this paper is very general and could be applied to a wide range of catalytic reactions. Following the steps outlined herein, such an analysis could potentially enable researchers to understand reaction mechanisms on a fundamental level and, on this basis, develop leads for new metal alloy catalysts.

Catalytic deactivation on methane steam reforming catalysts. 2. Kinetic study  

SciTech Connect

The kinetics of methane steam reforming reaction over an alumina-supported nickel catalyst was investigated at a temperature range of 640-740/sup 0/C in a flow reactor at atmospheric pressure. The experiments were performed varying the inlet concentration of methane, hydrogen, and water. A kinetic scheme of the Houghen-Watson type was satisfactorily proposed assuming the dissociative adsorption of CH/sub 4/ as the rate-limiting step, but this kinetic scheme can be easily replaced by a first-order kinetics (r/sub CH/4/sub / = kapparho/sub CH/4/sub /) for engineering purposes. Catalyst activation with H/sub 2/ and N/sub 2/ mixtures or with the reactant mixture results in the same extent of reaction.

Abstract In this study, the steam reforming of tar was catalyzed by dolomite, Ni/dolomite, and Ni/CeO2 for syngas production under different reaction temperature and weight hourly space velocity (WHSV, h?1). The tar was the major side product from the biomass gasification. Current results revealed that the nickel doped catalyst on dolomite with CO2 in the feed stream yielded the highest H2 and syngas production among all reaction conditions. Comparing to the use of dolomite, when Ni–dolomites was used as catalyst, the yield of H2 increased by 33%, the yield of syngas increased by 7%, and the yield of CH4 decreased by 59%. It was also found that the yield of syngas, H2, or CO under the Ni/dolomite catalyst were significant higher (p  CO2 concentration in the feed stream > reaction temperature > weight hourly space velocity.

Chemical Looping Reforming for H2, CO and Syngas Production  

SciTech Connect

We demonstrate that the extension of CLC onto oxidants beyond air opens new, highly efficient pathways for production of ultra-pure hydrogen, activation of CO{sub 2} via reduction to CO, and are currently working on production of syngas using nanocomposite Fe-BHA. CLR hold great potential due to fuel flexibility and CO{sub 2} capture. Chemical Looping Combustion (CLC) is a novel clean combustion technology which offers an elegant and highly efficient route for fossil fuel combustion. In CLC, combustion of a fuel is broken down into two spatially separated steps. In the reducer, the oxygen carrier (typically a metal) supplies the stoichiometric oxygen required for fuel combustion. In the oxidizer, the oxygen-depleted carrier is then re-oxidized with air. After condensation of steam from the effluent of the reducer, a high-pressure, high-purity sequestration-ready CO{sub 2} stream is obtained. In the present study, we apply the CLC principle to the production of high-purity H{sub 2}, CO, and syngas streams by replacing air with steam and/or CO{sub 2} as oxidant, respectively. Using H{sub 2}O as oxidant, pure hydrogen streams can be obtained. Similarly, using CO{sub 2} as oxidant, CO is obtained, thus opening an efficient route for CO{sub 2} utilization. Using steam and CO{sub 2} mixtures for carrier oxidation should thus allow production of syngas with adjustable CO:H{sub 2} ratios. Overall, these processes result in Chemical Looping Reforming (CLR), i.e. the net overall reaction is the steam and/or dry reforming of the respective fuel.

Online quality control methods for steam-gas reformers  

Science Journals Connector (OSTI)

This paper presents a classification of online quality control (QC) methods from the view of process control. The QC can be applied on the control loops from each of its three sides: the input (manipulative variable) side, the output (controlled variable) side and from the disturbance side. It was found that online QC can be direct or indirect, depending on the measures taken for quality. This classification can lead to interesting and new options for the control variables that otherwise would have been obscure. Once the proper control variable is selected (in terms of adequate representation of quality) it can be used for control systems analysis and design. Process application is presented for an industrial Steam Gas Reformer. The input is the fuel gas quality for which various options were presented. A correlation was obtained to relate heat input to simple measurements. The output hydrogen quality control options were discussed. Coil outlet temperature is adequate for a crude estimate of conversion, provided that S/C ratio is controlled. S/C ratio correlation was obtained to enable its estimation and control from simple measurements. A precise quality control of hydrogen can be achieved provided that COT is also controlled to protect reformer catalyst. An improved strategy can be implemented where both COT and conversion are controlled in a multivariable sense. This strategy is economically attractive, since it allows continuous manipulation of S/C ratio to the minimum required for COT control. Savings in fuel gas can be achieved accordingly. The feasibility of multivariable control was established via interaction analysis.

How fuel composition affects on-board reforming for fuel cell vehicles.  

SciTech Connect

Different blends of gasoline range hydrocarbons were investigated to determine the effect of aromatic, naphthenic, and paraffinic content on performance in an autothermal reformer. In addition, we investigated the effects of detergent, antioxidant, and oxygenate additives. These tests indicate that composition effects are minimal at temperatures of 800C and above, but at lower temperatures or at high gas hourly space velocities (GHSV approaching 100,000 h{sup -1} ) composition can have a large effect on catalyst performance. Fuels high in aromatic and naphthenic components were more difficult to reform. In addition, additives, such as detergents and oxygenates were shown to decrease reformer performance at lower temperatures.

Fiscal consolidation in the euro area: How much pain can structural reforms ease?  

Science Journals Connector (OSTI)

Abstract The IMF's Global Integrated Monetary and Fiscal model (GIMF) is used to examine the scope for structural reforms in the euro area to offset the negative impact of fiscal consolidation required to put public debt back on a sustainable path. The results suggest that structural reforms in core countries could be expected to offset the near-term negative impact on activity arising from the required fiscal consolidation. However, for the periphery, the results suggest that it would take several years before structural reforms could return the level of output back to its pre-consolidation path.

The role of civil society in health care reforms: An arena for hegemonic struggles  

Science Journals Connector (OSTI)

Abstract The present paper argues that current mainstream understandings of civil society as ontologically different from the state and essentially positive (either normative or functionally) are problematic in order to understand the development of health care reforms. The paper proposes to ground an explanation of the role of civil society in health care reforms in a Gramscian understanding of civil society as analytically different from the state, and as an arena for hegemonic struggles. The study of health care reform in Israel serves as a case study for this claim.

HYDROGEN GENERATION FROM PLASMATRON REFORMERS: A PROMISING TECHNOLOGY FOR NOX ADSORBER REGENERATION AND OTHER AUTOMOTIVE APPLICATIONS  

SciTech Connect

Plasmatron reformers are being developed at MIT and ArvinMeritor [1]. In these reformers a special low power electrical discharge is used to promote partial oxidation conversion of hydrocarbon fuels into hydrogen and CO. The partial oxidation reaction of this very fuel rich mixture is difficult to initiate. The plasmatron provides continuous enhanced volume initiation. To minimize electrode erosion and electrical power requirements, a low current, high voltage discharge with wide area electrodes is used. The reformers operate at or slightly above atmospheric pressure. Plasmatron reformers provide the advantages of rapid startup and transient response; efficient conversion of the fuel to hydrogen rich gas; compact size; relaxation or elimination of reformer catalyst requirements; and capability to process difficult to reform fuels, such as diesel and bio-oils. These advantages facilitate use of onboard hydrogen-generation technology for diesel exhaust after-treatment. Plasma-enhanced reformer technology can provide substantial conversion even without the use of a catalyst. Recent progress includes a substantial decrease in electrical power consumption (to about 200 W), increased flow rate (above 1 g/s of diesel fuel corresponding to approximately 40 kW of chemical energy), soot suppression and improvements in other operational features.. Plasmatron reformer technology has been evaluated for regeneration of NOx adsorber after-treatment systems. At ArvinMeritor tests were performed on a dual-leg NOx adsorber system using a Cummins 8.3L diesel engine both in a test cell and on a vehicle. A NOx adsorber system was tested using the plasmatron reformer as a regenerator and without the reformer i.e., with straight diesel fuel based regeneration as the baseline case. The plasmatron reformer was shown to improve NOx regeneration significantly compared to the baseline diesel case. The net result of these initial tests was a significant decrease in fuel penalty, roughly 50% at moderate adsorber temperatures. This fuel penalty improvement is accompanied by a dramatic drop in slipped hydrocarbon emissions, which decreased by 90% or more. Significant advantages are demonstrated across a wide range of engine conditions and temperatures. The study also indicated the potential to regenerate NOx adsorbers at low temperatures where diesel fuel based regeneration is not effective, such as those typical of idle conditions. Two vehicles, a bus and a light duty truck, have been equipped for plasmatron reformer NOx adsorber regeneration tests.

Steam-Methane Reformer Kinetic Computer Model with Heat Transfer and Geometry Options  

SciTech Connect

A kinetic computer model of a steam/methane reformer has been developed as a design and analytical tool for a fuel cell system's fuel conditioner. This model has reaction, geometry, flow arrangement, and heat transfer options. Model predictions have been compared to previous experimental data, and close agreement was obtained. Initially, the Leva-type, packed-bed, heat transfer correlations were used. However, calculations based upon the reacting, reformer gases indicate a considerably higher heat transfer coefficient for this reforme design. Data analysis from similar designs in the literature also shows this phenomenon. This is thought to be reaction-induced effect, brought about by the changing of gas composition, the increased gas velocity, the lower catalyst temperature during reaction, and the higher thermal and reaction gradients involved in compact fuel cell reformer designs. Future experimental work is planned to verify the model's predictions further.

Science Journals Connector (OSTI)

Isothermal vapor–liquid equilibrium (VLE) for tetrahydrothiophene + toluene and tetrahydrothiophene + o-xylene at 368.15 K and 383.15 K was measured with a recirculation still. Liquid- and vapor-phase compositions were determined with gas chromatography. All systems exhibit a small positive deviation from Raoult's law and show nearly ideal behavior. All VLE measurements passed the point test used. The experimental results were correlated with the Wilson model and compared with COSMO-SAC predictive models. COSMO-SAC predictions show a slight negative deviation from Raoult's law for all systems measured. Raoult's law can be used to describe all systems studied. The activity coefficients at infinite dilution are presented.

Health system reform in rural China: Voices of healthworkers and service-users  

Science Journals Connector (OSTI)

Abstract Like many other countries China is undergoing major health system reforms, with the aim of providing universal health coverage, and addressing problems of low efficiency and inequity. The first phase of the reforms has focused on strengthening primary care and improving health insurance coverage and benefits. The aim of the study was to explore the impacts of these reforms on healthworkers and service-users at township level, which has been the major target of the first phase of the reforms. From January to March 2013 we interviewed eight health officials, 80 township healthworkers and 80 service-users in eight counties in Zhejiang and Yunnan provinces, representing rich and poor provinces respectively. Thematic analysis identified key themes around the impacts of the health reforms. We found that some elements of the reforms may actually be undermining primary care. While the new health insurance system was popular among service-users, it was criticised for contributing to fast-growing medical costs, and for an imbalance of benefits between outpatient and inpatient services. Salary reform has guaranteed healthworkers' income, but greatly reduced their incentives. The essential drug list removed perverse incentives to overprescribe, but led to falls in income for healthworkers, and loss of autonomy for doctors. Serious problems with drug procurement also emerged. The unintended consequences have included a brain drain of experienced healthworkers from township hospitals, and patients have flowed to county hospitals at greater cost. In conclusion, in the short term resources must be found to ensure rural healthworkers feel appropriately remunerated and have more clinical autonomy, measures for containment of the medical costs must be taken, and drug procurement must show increased transparency and accountability. More importantly the study shows that all countries undergoing health reforms should elicit the views of stakeholders, including service-users, to avoid and address unintended consequences.

Steam Reforming on Transition-metal Carbides from Density-functional Theory  

SciTech Connect

A screening study of the steam reforming reaction on clean and oxygen covered early transition-metal carbides surfaces is performed by means of density-functional theory calculations. It is found that carbides provide a wide spectrum of reactivities, from too reactive via suitable to too inert. Several molybdenum-based systems are identified as possible steam reforming catalysts. The findings suggest that carbides provide a playground for reactivity tuning, comparable to the one for pure metals.

Lignin removal and benzene–alcohol extraction effects on lignin measurements of the hydrothermal pretreated bamboo substrate  

Science Journals Connector (OSTI)

Abstract Lignin content of hydrothermal pretreated bamboo chips was determined by the two methods: TAPPI standard method (222om-06) and TAPPI standard method without benzene–alcohol extraction (BAE). The results showed that including BAE resulted in lower Klason lignin (KL) and acid soluble lignin (ASL) measurements in the prehydrolyzed substrate, that is to say, BAE removed parts of KL and ASL. Therefore, the TAPPI standard method should be modified by omitting the BAE for lignin measurements of pretreated substrate. The following lignin removal analysis suggested that lignin was removed from the bamboo substrate during pretreatment by a combination of degradation reaction and deconstruction; thereafter the pseudo lignin generated in the hydrothermal pretreatment and condensation reaction between the lignin fragments accounted for the later KL increase.

DATA QUALITY OBJECTIVES FOR SELECTING WASTE SAMPLES FOR BENCH-SCALE REFORMER TREATABILITY STUDIES  

SciTech Connect

This document describes the data quality objectives to select archived samples located at the 222-S Laboratory for Bench-Scale Reforming testing. The type, quantity, and quality of the data required to select the samples for Fluid Bed Steam Reformer testing are discussed. In order to maximize the efficiency and minimize the time to treat Hanford tank waste in the Waste Treatment and Immobilization Plant, additional treatment processes may be required. One of the potential treatment processes is the fluidized bed steam reformer. A determination of the adequacy of the fluidized bed steam reformer process to treat Hanford tank waste is required. The initial step in determining the adequacy of the fluidized bed steam reformer process is to select archived waste samples from the 222-S Laboratory that will be used in a bench scale tests. Analyses of the selected samples will be required to confirm the samples meet the shipping requirements and for comparison to the bench scale reformer (BSR) test sample selection requirements.

Steam reforming of low-level mixed waste  

SciTech Connect

The U.S. department of Energy (DOE) is responsible for the treatment and disposal of an inventory of approximately 160,000 tons of Low-Level Mixed Waste (LLMW). Most of this LLMW is stored in drums, barrels and steel boxes at 20 different sites throughout the DOE complex. The basic objective of low-level mixed waste treatment systems is to completely destroy the hazardous constituents and to simultaneously isolate and capture the radionuclides in a superior final waste form such as glass. The DOE is sponsoring the development of advanced technologies that meet this objective while achieving maximum volume reduction, low-life cycle costs and maximum operational safety. ThermoChem, Inc. is in the final stages of development of a steam-reforming system capable of treating a wide variety of DOE low-level mixed waste that meets these objectives. The design, construction, and testing of a nominal 1 ton/day Process Development Unit is described.

Second Law Analysis of a Solar Methane Reforming System  

Science Journals Connector (OSTI)

Abstract In this paper, we present the results of a Second Law analysis of a highly efficient, solar thermochemical reaction system for the production of syngas using micro- and meso-channel process technology. The evaluation includes the initial conversion of solar energy/exergy into physical energy/exergy and its subsequent conversion into chemical energy/exergy through the catalytic, endothermic reforming reaction, including quantifications of exergy destruction for components and the overall system. Possible applications include the combustion of the product syngas in a hybrid, solar/natural gas power plant, providing an efficient solar augment to the natural gas fuel; the thermochemical storage of solar energy, as part of an open or closed-cycle storage process; the production of hydrogen for use in fuel cells and for other purposes; and the production of synthetic fuels such as methanol or long-chain hydrocarbons. The analyses show that the overall process is exergetically-efficient and consistent with First Law and economic analyses. Finally, opportunities for improving the exergetic efficiency of the process are identified and discussed

DURABILITY TESTING OF FLUIDIZED BED STEAM REFORMER (FBSR) WASTE FORMS  

SciTech Connect

Fluidized Bed Steam Reforming (FBSR) is being considered as a potential technology for the immobilization of a wide variety of high sodium aqueous radioactive wastes. The addition of clay and a catalyst as co-reactants converts high sodium aqueous low activity wastes (LAW) such as those existing at the Hanford and Idaho DOE sites to a granular ''mineralized'' waste form that may be made into a monolith form if necessary. Simulant Hanford and Idaho high sodium wastes were processed in a pilot scale FBSR at Science Applications International Corporation (SAIC) Science and Technology Applications Research (STAR) facility in Idaho Falls, ID. Granular mineral waste forms were made from (1) a basic Hanford Envelope A low-activity waste (LAW) simulant and (2) an acidic INL simulant commonly referred to as sodium-bearing waste (SBW). The FBSR waste forms were characterized and the durability tested via ASTM C1285 (Product Consistency Test), the Environmental Protection Agency (EPA) Toxic Characteristic Leaching Procedure (TCLP), and the Single Pass Flow Through (SPFT) test. The durability of the FBSR waste form products was tested in order to compare the measured durability to previous FBSR waste form testing on Hanford Envelope C waste forms that were made by THOR Treatment Technologies (TTT) and to compare the FBSR durability to vitreous LAW waste forms, specifically the Hanford low activity waste (LAW) glass known as the Low-activity Reference Material (LRM). The durability of the FBSR waste form is comparable to that of the LRM glass for the test responses studied.

Reform towards National Health Insurance in Malaysia: The equity implications  

Science Journals Connector (OSTI)

Objective This paper assesses the potential equity impact of Malaysia's projected reform of its current tax financed system towards National Health Insurance (NHI). Methods The Kakwani's progressivity index was used to assess the equity consequences of the new NHI system (with flat rate NHI scheme) compared to the current tax financed system. It was also used to model a proposed system (with a progressive NHI scheme) that can generate the same amount of funding more equitably. Results The new NHI system would be less equitable than the current tax financed system, as evident from the reduction of Kakwani's index to 0.168 from 0.217. The new flat rate NHI scheme, if implemented, would reduce the progressivity of the health finance system because it is a less progressive finance source than that of general government revenue. We proposed a system with a progressive NHI scheme that generates the same amount of funding whilst preserving the equity at the Kakwani's progressivity index of 0.213. Conclusions A NHI system with a progressive NHI scheme is proposed to be implemented to raise health funding whilst preserving the equity in health care financing.

Fuel processing for fuel cells: a model for fuel conversion and carbon formation in the adiabatic steam reformer  

SciTech Connect

In present fuel cell power plants the fuel processor is a catalytic steam reformer which is limited to the use of fuels such as naphtha and natural gas. The sulfur content of these feeds must be reduced to low levels by hydrotreatment before contacting the nickel catalyst in the reformer. However, future fuel cell power plants may be required to ue coal-derived liquid fuel or heavy petroleum distillates which are more difficult to hydrotreat and reform. To meet this requirement, an adiabatic steam reformer is being developed by United Technologies Corporation with the support of the Electric Power Research Institute. In the adiabatic reformer, air is added to the process stream to provide, by combustion, the heat for endothermic reforming in a catalyst bed. In the inlet section of the reformer, air and fuel combust, and reforming is initiated on special catalysts whose primary functon is to prevent formation and accumulation of carbon. Following the inlet section, catalysts with high activity for steam reforming complete the conversion of the remaining fuel, principally methane. The objective of the present program is to establish a reactor model for the adiabatic reformer which would predict process stream compositions and temperatures and include carbon formation processes. Progress is reported on the four tasks: (1) determine rate expressions for catalytic reactions occurring in the adiabatic reformer; (2) establish a reactor model to predict process stream compositions in the adiabatic reformer using data from Task 1 for cataytic reactions and data from the literature for homogeneous gas-phase reactions; (3) determine critical conditions for carbon formation on selected catalysts using microbalance experiments; and (4) establish a model to predict carbon formation by combination of the model for process stream composition from Task 2 and data for carbon formation from Task 3.

Method for the operation of internal combustion engines. [gasification reactor for reforming gasoline  

SciTech Connect

This is a method for the operation of internal combustion engines which is designed to decontaminate the exhaust gases. The method includes: feeding a gasification air stream into a gasification reactor; feeding fuel into the same gasification reactor; combining the fuel with the gasification air into a homogeneous fuel-air mixture in the gasification reactor; and converting the fuel-air mixture by partial combustion into a soot -free reformed gas. Then, the reformed gas is fed from the gasification reactor to a mixer where the reformed gas is mixed with combustion air and the reformed gas-air mixture is fed to the internal combustion engine for further combustion with the result that there is intensive decontamination of the exhaust gases which thereby reduces air pollution. The reformed gas temperature is adjusted low for maximum engine output, and is adjusted higher for lower engine temperatures in order to obtain a reformed gas which is richer in hydrogen and thereby produce exhaust gases which are lower in harmful substances. In reference to the exhaust gases in an internal combustion engine, this method achieves the highest possible degree of decontamination, not only of the carbon monoxide and hydrocarbons , but also of the nitrous oxides in the exhaust gases. Using this method, the internal combustion engine can be operated not only with high-test, no-knock gasoline, but also with cheap, lead-free low octane, straight-run gasoline which is low in aromatics and olefins, which normally do not have no-knock properties, and the internal combustion engine can be operated with the lowest possible fuel consumption. The gasification reactor operates through chemical reaction in the presence of a catalyst. Optionally, this method may include a return of part of the reformed gas to the input of the gasification reactor.

Lineage and land reforms in Malawi: Do matrilineal and patrilineal landholding systems represent a problem for land reforms in Malawi?  

Science Journals Connector (OSTI)

Abstract Based on government statistics and interviews with villagers across Malawi this article argues that customary matrilineal and patrilineal land tenure systems serve to weaken security of land tenure for some family members as well as obstructing the creation of gender-neutral inheritance of lands. Data from the National Census of Agriculture and Livestock 2007and the 2008 Population and Housing Census are used to characterize marriage systems and landholding patterns of local communities. Marriage systems correspond to customary land-tenure patterns of matrilineal or patrilineal cultures. The differences between the two ways of land holding represent a challenge for land reforms aimed at unifying rules for land tenure and land devolution. Drawing on an analogy of the resilience of the patrilineal land holding system in Norway, we argue that it will be difficult to remove the preferential rights of lineage members directly. We recommend that, instead of creating a unified national system, existing land rights should be formally recognized and circumscribed by fair procedures. A well-designed landholding system should aim to ease the transitions of diverse customary tenure systems towards the requirements of a modern large-scale society.

Simultaneous carbon dioxide and steam reforming of methane to syngas over NiO-CaO catalyst  

SciTech Connect

Steam reforming, Co{sub 2} reforming, and simultaneous steam and CO{sub 2} reforming of methane to CO and H{sub 2} over NiO-CaO catalyst (without any prereduction treatment) at different temperatures (700--850 C) and space velocities (5000--70,000 cm{sup 3}/g{center_dot}h) are investigated. The catalyst is characterized by XRD, XPS, and temperature-programmed reduction (TPR). The catalyst showed high activity/selectivity in both the steam and CO{sub 2} reforming reactions and the simultaneous steam and CO{sub 2} reforming. In the CO{sup 2} reforming, the coke deposition on the catalyst is found to be very fast. However, when the CO{sub 2} reforming is carried out simultaneously with the steam reforming, the coke deposition on the catalyst is drastically reduced. By the simultaneous CO{sub 2} and steam reforming (at {ge} 800 C and space velocity of about 20,000--30,000 cm{sup 3}/g{center_dot}h)m methane can be converted almost completely to syngas with 100% selectivity for both CO and H{sub 2}. The H{sub 2}/CO ratio in products can be varied between 1.5 and 2.5 quite conveniently by manipulating the relative concentration of steam and CO{sub 2} in the feed.

Development of a Catalyst/Sorbent for Methane Reforming  

SciTech Connect

This project led to the further development of a combined catalyst and sorbent for improving the process technology required for converting CH{sub 4} and/or CO into H{sub 2} while simultaneously separating the CO{sub 2} byproduct all in a single step. The new material is in the form of core-in-shell pellets such that each pellet consists of a CaO core surrounded by an alumina-based shell capable of supporting a Ni catalyst. The Ni is capable of catalyzing the reactions of steam with CH{sub 4} or CO to produce H{sub 2} and CO{sub 2}, whereas the CaO is capable of absorbing the CO{sub 2} as it is produced. The absorption of CO{sub 2} eliminates the reaction inhibiting effects of CO{sub 2} and provides a means for recovering the CO{sub 2} in a useful form. The present work showed that the lifecycle performance of the sorbent can be improved either by incorporating a specific amount of MgO in the material or by calcining CaO derived from limestone at 1100 C for an extended period. It also showed how to prepare a strong shell material with a large surface area required for supporting an active Ni catalyst. The method combines graded particles of {alpha}-alumina with noncrystalline alumina having a large specific surface area together with a strength promoting additive followed by controlled calcination. Two different additives produced good results: 3 {micro}m limestone and lanthanum nitrate which were converted to their respective oxides upon calcination. The oxides partially reacted with the alumina to form aluminates which probably accounted for the strength enhancing properties of the additives. The use of lanthanum made it possible to calcine the shell material at a lower temperature, which was less detrimental to the surface area, but still capable of producing a strong shell. Core-in-shell pellets made with the improved shell materials and impregnated with a Ni catalyst were used for steam reforming CH{sub 4} at different temperatures and pressures. Under all conditions tested, the CH{sub 4} conversion was large (>80%) and nearly equal to the predicted thermodynamic equilibrium level as long as CO{sub 2} was being rapidly absorbed. Similar results were obtained with both shell material additives. Limited lifecycle tests of the pellets also produced similar results that were not affected by the choice of additive. However, during each lifecycle test the period during which CO{sub 2} was rapidly absorbed declined from cycle to cycle which directly affected the corresponding period when CH{sub 4} was reformed rapidly. Therefore, the results showed a continuing need for improving the lifecycle performance of the sorbent. Core-in-shell pellets with the improved shell materials were also utilized for conducting the water gas shift reaction in a single step. Three different catalyst formulations were tested. The best results were achieved with a Ni catalyst, which proved capable of catalyzing the reaction whether CO{sub 2} was being absorbed or not. The calcined alumina shell material by itself also proved to be a very good catalyst for the reaction as long as CO{sub 2} was being fully absorbed by the core material. However, neither the alumina nor a third formulation containing Fe{sub 2}O{sub 3} were good catalysts for the reaction when CO{sub 2} was not absorbed by the core material. Furthermore, the Fe{sub 2}O{sub 3}-containing catalyst was not as good as the other two catalysts when CO{sub 2} was being absorbed.

An Innovative Injection and Mixing System for Diesel Fuel Reforming  

SciTech Connect

This project focused on fuel stream preparation improvements prior to injection into a solid oxide fuel cell reformer. Each milestone and the results from each milestone are discussed in detail in this report. The first two milestones were the creation of a coking formation test rig and various testing performed on this rig. Initial tests indicated that three anti-carbon coatings showed improvement over an uncoated (bare metal) baseline. However, in follow-up 70 hour tests of the down selected coatings, Scanning Electron Microscope (SEM) analysis revealed that no carbon was generated on the test specimens. These follow-up tests were intended to enable a down selection to a single best anti-carbon coating. Without the formation of carbon it was impossible to draw conclusions as to which anti-carbon coating showed the best performance. The final 70 hour tests did show that AMCX AMC26 demonstrated the lowest discoloration of the metal out of the three down selected anti-carbon coatings. This discoloration did not relate to carbon but could be a useful result when carbon growth rate is not the only concern. Unplanned variations in the series of tests must be considered and may have altered the results. Reliable conclusions could only be drawn from consistent, repeatable testing beyond the allotted time and funding for this project. Milestones 3 and 4 focused on the creation of a preheating pressure atomizer and mixing chamber. A design of experiment test helped identify a configuration of the preheating injector, Build 1, which showed a very uniform fuel spray flow field. This injector was improved upon by the creation of a Build 2 injector. Build 2 of the preheating injector demonstrated promising SMD results with only 22psi fuel pressure and 0.7 in H2O of Air. It was apparent from testing and CFD that this Build 2 has flow field recirculation zones. These recirculation zones may suggest that this Build 2 atomizer and mixer would require steam injection to reduce the auto ignition potential. It is also important to note that to achieve uniform mixing within a short distance, some recirculation is necessary. Milestone 5 generated CFD and FEA results that could be used to optimize the preheating injector. CFD results confirmed the recirculation zones seen in test data and confirmed that the flow field would not change when attached to a reformer. The FEA predicted fuel wetted wall temperatures which led to several suggested improvements that could possibly improve nozzle efficiency. Milestone 6 (originally an optional task) took a different approach than the preheating pressure atomizer. It focused on creation and optimization of a piezoelectric injector which could perform at extremely low fuel pressures. The piezoelectric atomizer showed acceptable SMD results with fuel pressure less than 1.0 psig and air pressure less than 1.0 in H2O. These SMD values were enhanced when a few components were changed, and it is expected would improve further still at elevated air temperatures. It was demonstrated that the piezoelectric injector could accomplish the desired task. The addition of phase tracking and a burst mode to the frequency controller increased the usability of the piezoelectric injector. This injector is ready to move on to the next phase of development. Engine Components has met the required program milestones of this project. Some of the Milestones were adjusted to allow Milestone 6 to be completed in parallel with the other Milestones. Because of this, Task 3.10 and 3.13 were made optional instead of Milestone 6. Engine Components was extremely grateful for the support that was provided by NETL in support of this work.

Durability Testing of Fluidized Bed Steam Reforming Products  

SciTech Connect

Fluidized Bed Steam Reforming (FBSR) is being considered as a potential technology for the immobilization of a wide variety of radioactive wastes but especially aqueous high sodium wastes at the Hanford site, at the Idaho National Laboratory (INL), and at the Savannah River Site (SRS). The FBSR technology converts organic compounds to CO{sub 2} and H{sub 2}O, converts nitrate/nitrite species to N{sub 2}, and produces a solid residue through reactions with superheated steam, the fluidizing media. If clay is added during processing a ''mineralized'' granular waste form can be produced. The mineral components of the waste form are primarily Na-Al-Si (NAS) feldspathoid minerals with cage-like and ring structures and iron bearing spinel minerals. The cage and ring structured minerals atomically bond radionuclides like Tc{sup 99} and Cs{sup 137} and anions such as SO{sub 4}, I, F, and Cl. The spinel minerals appear to stabilize Resource Conservation and Recovery Act (RCRA) hazardous species such as Cr and Ni. Durability testing of the FBSR products was performed using ASTM C1285 (Product Consistency Test) and the Environmental Protection Agency (EPA) Toxic Characteristic Leaching Procedure (TCLP). The FBSR mineral products (bed and fines) evaluated in this study were found to be two orders of magnitude more durable than the Hanford Low Activity Waste (LAW) glass requirement of 2 g/m{sup 2} release of Na{sup +}. The PCT responses for the FBSR samples tested were consistent with results from previous FBSR Hanford LAW product testing. Differences in the response can be explained by the minerals formed and their effects on PCT leachate chemistry.

Effects of Current on Microcosmic Properties of Catalyst and Reforming of Bio-oil  

Science Journals Connector (OSTI)

Highly effective production of hydrogen from bio-oil was achieved by using a low-temperature electrochemical catalytic reforming approach over the conventional Ni-based reforming catalyst (NiO-Al2O3), where an AC electronic current passed through the catalyst bed. The promoting effects of current on the bio-oil reforming were studied. It was found that the performance of the bio-oil reforming was remarkably enhanced by the current which passed through the catalyst. The effects of currents on the microcosmic properties of the catalyst, including the Brunauer–Emmett–Teller (BET) surface area, pore diameter, pore volume, the size of the crystallites and the reduction level of NiO into Ni, were carefully characterized by BET, X-ray diffraction, X-ray photoelectron spectroscopy, and scanning electron microscope. The desorption of the thermal electrons from the electrified catalyst was directly observed by the TOF (time of flight) measurements. The mechanism of the electrochemical catalytic reforming of bio-oil is discussed based on the above investigation.

Plasma steam reforming of E85 for hydrogen rich gas production  

Science Journals Connector (OSTI)

E85 (85?vol% ethanol and 15?vol% gasoline) is a partly renewable fuel that is increasing in supply availability. Hydrogen production from E85 for fuel cell or internal combustion engine applications is a potential method for reducing CO2 emissions. Steam reforming of E85 using a nonthermal plasma (pulse corona discharge) reactor has been exploited at low temperature (200–300?°C) without external heating, diluent gas, oxidant or catalyst in this work. Several operational parameters, including the discharge current, E85 concentration and feed flow rate, have been investigated. The results show that hydrogen rich gases (63–67% H2 and 22–29% CO, with small amounts of CO2, C2 hydrocarbons and CH4) can be produced by this method. A comparison with ethanol reforming and gasoline reforming under identical conditions has also been made and the behaviour of E85 reforming is found to be close to that of ethanol reforming with slightly higher C2 hydrocarbons yields.

Experimental and computational investigations of sulfur-resistant bimetallic catalysts for reforming of biomass gasification products  

SciTech Connect

A combination of density functional theory (DFT) calculations and experimental studies of supported catalysts was used to identify H{sub 2}S-resistant biomass gasification product reforming catalysts. DFT calculations were used to search for bimetallic, nickel-based (1 1 1) surfaces with lower sulfur adsorption energies and enhanced ethylene adsorption energies. These metrics were used as predictors for H{sub 2}S resistance and activity toward steam reforming of ethylene, respectively. Relative to Ni, DFT studies found that the Ni/Sn surface alloy exhibited enhanced sulfur resistance and the Ni/Ru system exhibited an improved ethylene binding energy with a small increase in sulfur binding energy. A series of supported bimetallic nickel catalysts was prepared and screened under model ethylene reforming conditions and simulated biomass tar reforming conditions. The observed experimental trends in activity were consistent with theoretical predictions, with observed reforming activities in the order Ni/Ru > Ni > Ni/Sn. Interestingly, Ni/Ru showed a high level of resistance to sulfur poisoning compared with Ni. This sulfur resistance can be partly explained by trends in sulfur versus ethylene binding energy at different types of sites across the bimetallic surface.

Comparison of several glycerol reforming methods for hydrogen and syngas production using Gibbs energy minimization  

Science Journals Connector (OSTI)

Abstract This paper focuses on the comparison of different glycerol reforming technologies aimed to hydrogen and syngas production. The reactions of steam reforming, partial oxidation, autothermal reforming, dry reforming and supercritical water gasification were analyzed. For this, the Gibbs energy minimization approach was used in combination with the virial equation of state. The validation of the model was made between the simulations of the proposed model and both, simulated and experimental data obtained in the literature. The effects of modifications in the operational temperature, operational pressure and reactants composition were analyzed with regard to composition of the products. The effect of coke formation was discussed too. Generally, higher temperatures and lower pressures resulted in higher hydrogen and syngas production. All reforming technologies demonstrated to be feasible for use in hydrogen or synthesis gas production in respect of the products composition. The proposed model showed good predictive ability and low computational time (close to 1 s) to perform the calculation of the combined chemical and phase equilibrium for all systems analyzed.

The impact of higher education reform on research performance of Chinese universities  

Science Journals Connector (OSTI)

Abstract To address challenges for the 21st century, the Chinese government initiated a series of higher education reforms to support the open-door policy of China. Part of the education reform involves an allocation of additional funding of US$ 20 billion to a group of 112 universities to strengthen their research capabilities with an ultimate goal for them to become national catalysts for raising Chinese educational standards to world-class quality. The target university group is known as Project 211 universities. Other non-Project 211 universities have not received such resources. This paper is the first to provide rigorous assessment of the impact of the latest higher education reform on the performance of Chinese universities for the period 2007–2009. Evidence from meta-frontier analysis reveals that the reform had intended impact on the Chinese universities in our sample. Project 211 universities, on average, performed better than the non-Project 211 group and managerial inefficiency is the key attribute of low overall productive efficiency. Unlike Project 211 universities, non-Project 211 universities have limited access to the best available technology. However, the Malmquist productivity index suggests that Project 211 universities experienced more severe productivity regress than non-Project 211 universities. Our mixed evidence may reflect economy-wide conditions and warrant further research. Nevertheless, evidence suggests that the higher education reforms should be broadened to allow non-Project 211 universities to compete with Project 211 universities for additional financial support required to enhance their research capability.

Policy processes and police reform: Examining similarities and differences between Scotland and the Netherlands  

Science Journals Connector (OSTI)

Abstract During 2013 the national governments of both the Netherlands and Scotland have introduced radical reforms which have replaced largely autonomous regional police forces with a national police service. Despite these structural similarities, however, there are important differences in the underlying processes which have shaped these reforms and the broader narratives about policing which have informed public and policy discourses. The purpose of this paper is to understand the underlying dynamics of these police reforms. Following an overview of concepts drawn from the public policy literature regarding policy change, the paper describes in detail the structural changes to policing that have occurred in both countries. These structural changes relate not just to the spatial re-organization of policing but also to the structure of police governance and accountability. The focus then shifts to disentangling key aspects of the decision-making processes which led to the reforms drawing on Kingdon's analysis of policy change and policy formation. The paper concludes with a broader discussion of the similarities and differences in police reform in the two countries, highlighting important issues regarding the significance of political context, debates around localism and policing, and narratives regarding a normative vision of the police role.

High-temperature gas-cooled-reactor steam-methane reformer design  

SciTech Connect

The concept of the long distance transportation of process heat energy from a High Temperature Gas Cooled Reactor (HTGR) heat source, based on the steam reforming reaction, is currently being evaluated as an energy source/application for use early in the 21st century. The steam-methane reforming reaction is an endothermic reaction at temperatures approximately 700/sup 0/C and higher, which produces hydrogen, carbon monoxide and carbon dioxide. The heat of the reaction products can then be released, after being pumped to industrial site users, in a methanation process producing superheated steam and methane which is then returned to the reactor plant site. In this application the steam reforming reaction temperatures are produced by the heat energy from the core of the HTGR through forced convection of the primary or secondary helium circuit to the catalytic chemical reactor (steam reformer). This paper summarizes the design of a helium heated steam reformer utilized in conjunction with a 1170 MW(t) intermediate loop, 850/sup 0/C reactor outlet temperature, HTGR process heat plant concept. This paper also discusses various design considerations leading to the mechanical design features, the thermochemical performance, materials selection and the structural design analysis.

Development of Sulfur and Carbon Tolerant Reforming Alloy Catalysts Aided Fundamental Atomistic Insights  

SciTech Connect

Current hydrocarbon reforming catalysts suffer from rapid carbon and sulfur poisoning. Even though there is a tremendous incentive to develop more efficient catalysts, these materials are currently formulated using inefficient trial and error experimental approaches. We have utilized a hybrid experimental/theoretical approach, combining quantum Density Functional Theory (DFT) calculations and various state-of-the-art experimental tools, to formulate carbon tolerant reforming catalysts. We have employed DFT calculations to develop molecular insights into the elementary chemical transformations that lead to carbon poisoning of Ni catalysts. Based on the obtained molecular insights, we have identified, using DFT quantum calculation, various Ni alloy catalysts as potential carbon tolerant reforming catalysts. The alloy catalysts were synthesized and tested in steam reforming and partial oxidation of methane, propane, and isooctane. We demonstrated that the alloy catalysts are much more carbon-tolerant than monometallic Ni catalysts under nearly stoichiometric steam-to-carbon ratios. Under these conditions, monometallic Ni is rapidly poisoned by sp2 carbon deposits. The research approach is distinguished by two characteristics: (a) knowledge-based, bottomup approach, compared to the traditional trial and error approach, allows for a more efficient and systematic discovery of improved catalysts. (b) the focus is on exploring alloy materials which have been largely unexplored as potential reforming catalysts.

Improving gasoline direct injection (GDI) engine efficiency and emissions with hydrogen from exhaust gas fuel reforming  

Science Journals Connector (OSTI)

Abstract Exhaust gas fuel reforming has been identified as a thermochemical energy recovery technology with potential to improve gasoline engine efficiency, and thereby reduce CO2 in addition to other gaseous and particulate matter (PM) emissions. The principle relies on achieving energy recovery from the hot exhaust stream by endothermic catalytic reforming of gasoline and a fraction of the engine exhaust gas. The hydrogen-rich reformate has higher enthalpy than the gasoline fed to the reformer and is recirculated to the intake manifold, i.e. reformed exhaust gas recirculation (REGR). The REGR system was simulated by supplying hydrogen and carbon monoxide (CO) into a conventional EGR system. The hydrogen and CO concentrations in the REGR stream were selected to be achievable in practice at typical gasoline exhaust temperatures. Emphasis was placed on comparing REGR to the baseline gasoline engine, and also to conventional EGR. The results demonstrate the potential of REGR to simultaneously increase thermal efficiency, reduce gaseous emissions and decrease PM formation.

Hydrogen Production From Crude Bio-oil and Biomass Char by Electrochemical Catalytic Reforming  

Science Journals Connector (OSTI)

We reports an efficient approach for production of hydrogen from crude bio-oil and biomass char in the dual fixed-bed system by using the electrochemical catalytic reforming method. The maximal absolute hydrogen yield reached 110.9 g H2/kg dry biomass. The product gas was a mixed gas containing 72%H2, 26%CO2, 1.9%CO, and a trace amount of CH4. It was observed that adding biomass char (a by-product of pyrolysis of biomass) could remarkably increase the absolute H2 yield (about 20%-50%). The higher reforming temperature could enhance the steam reforming reaction of organic compounds in crude bio-oil and the reaction of CO and H2O. In addition, the CuZn-Al2O3 catalyst in the water-gas shift bed could also increase the absolute H2 yield via shifting CO to CO2.

Catalytic performances of Ni–CaO–mayenite in CO2 sorption enhanced steam methane reforming  

Science Journals Connector (OSTI)

Abstract Ni–CaO–mayenite (Ca12Al14O33) catalysts for the CO2 Sorption Enhanced Steam Methane Reforming (SE-SMR) have been developed using the microwave assisted self-combustion method of preparation. The sorption of CO2 by CaO shifts the steam reforming and the Water Gas Shift reaction (WGS) towards H2 production and favors the heat balance of the global reaction. The CO2 sorption has been studied on materials with different CaO/Ca12Al14O33 ratios and for different types of preparation. The specific surface area of materials, the temperature of Ni phases' reducibility and CO2 sorption are all essential for material efficiency. The Ni–CA75MM catalyst was the most active and stable in methane steam reforming with CO2 sorption, even at an unusually low temperature (650 °C).

Implementing health care reform in the United States: Intergovernmental politics and the dilemmas of institutional design  

Science Journals Connector (OSTI)

Abstract The Affordable Care Act (ACA) was enacted, and continues to operate, under conditions of political polarization. In this article, we argue that the law's intergovernmental structure has amplified political conflict over its implementation by distributing governing authority to political actors at both levels of the American federal system. We review the ways in which the law's demands for institutional coordination between federal and state governments (and especially the role it preserves for governors and state legislatures) have created difficulties for rolling out health-insurance exchanges and expanding the Medicaid program. By way of contrast, we show how the institutional design of the ACA's regulatory reforms of the insurance market, which diminish the reform's political salience, has allowed for considerably less friction during the implementation process. This article thus highlights the implications of multi-level institutional designs for the post-enactment politics of major reforms.

Process and apparatus for the production of hydrogen by steam reforming of hydrocarbon  

DOE Patents (OSTI)

In the steam reforming of hydrocarbon, particularly methane, under elevated temperature and pressure to produce hydrogen, a feed of steam and hydrocarbon is fed into a first reaction volume containing essentially only reforming catalyst to partially reform the feed. The balance of the feed and the reaction products of carbon dioxide and hydrogen are then fed into a second reaction volume containing a mixture of catalyst and adsorbent which removes the carbon dioxide from the reaction zone as it is formed. The process is conducted in a cycle which includes these reactions followed by countercurrent depressurization and purge of the adsorbent to regenerate it and repressurization of the reaction volumes preparatory to repeating the reaction-sorption phase of the cycle.

Solar steam reforming of natural gas integrated with a gas turbine power plant  

Science Journals Connector (OSTI)

Abstract This paper shows a hybrid power plant wherein solar steam reforming of natural gas and a steam injected gas turbine power plant are integrated for solar syngas production and use. The gas turbine is fed by a mixture of natural gas and solar syngas (mainly composed of hydrogen and water steam) from mid-low temperature steam reforming reaction whose heat duty is supplied by a parabolic trough Concentrating Solar Power plant. A comparison is made between a traditional steam injected gas turbine and the proposed solution to underline the improvements introduced by the integration with solar steam reforming of the natural gas process. The paper also shows how solar syngas can be considered as an energy vector consequent to solar energy conversion effectiveness and the natural gas pipeline as a storage unit, thus accomplishing the idea of a smart energy grid.

Steam reforming on transition-metal carbides from density-functional theory  

E-Print Network (OSTI)

A screening study of the steam reforming reaction (CH_4 + H_2O -> CO + 3H_2) on early transition-metal carbides (TMC's) is performed by means of density-functional theory calculations. The set of considered surfaces includes the alpha-Mo_2C(100) surfaces, the low-index (111) and (100) surfaces of TiC, VC, and delta-MoC, and the oxygenated alpha-Mo_2C(100) and TMC(111) surfaces. It is found that carbides provide a wide spectrum of reactivities towards the steam reforming reaction, from too reactive via suitable to too inert. The reactivity is discussed in terms of the electronic structure of the clean surfaces. Two surfaces, the delta-MoC(100) and the oxygen passivated alpha-Mo_2C(100) surfaces, are identified as promising steam reforming catalysts. These findings suggest that carbides provide a playground for reactivity tuning, comparable to the one for pure metals.
