Propane, Liquefied Petroleum Gas (LPG)  

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

Propane: Liquefied Petroleum Gas (LPG) Propane: Liquefied Petroleum Gas (LPG) Ford F-150 (Dual-Fuel LPG) Propane or liquefied petroleum gas (LPG) is a clean-burning fossil fuel that can be used to power internal combustion engines. LPG-fueled vehicles can produce significantly lower amounts of some harmful emissions and the greenhouse gas carbon dioxide (CO2). LPG is usually less expensive than gasoline, it can be used without degrading vehicle performance, and most LPG used in U.S. comes from domestic sources. The availability of LPG-fueled light-duty passenger vehicles is currently limited. A few light-duty vehicles-mostly larger trucks and vans-can be ordered from a dealer with a prep-ready engine package and converted to use propane. Existing conventional vehicles can also be converted for LPG use.

Science Journals Connector (OSTI)

A new design has been used for cooling GaAs/AlxGa1?xAs sample to ultra-low-temperatures. The sample, with electrical contacts directly soldered to the sintered silver powder heat exchangers, was immersed in liquid  3He, which was cooled by a PrNI5 nuclear refrigerator. The data analysis shows that the two-dimensional electron gas (2DEG) was cooled to 4.0 mK at the refrigerator base temperature Tb of 2.0 mK. The design with heat exchanger cooling is applicable to any ultra-low-temperature transport measurements of 2DEG system.

16 - Ultra-low nitrogen oxides (NOx) emissions combustion in gas turbine systems  

Science Journals Connector (OSTI)

Abstract: The historical development of gas turbine low \\{NOx\\} combustion from the pioneering NASA work in the early 1970s to the present generation of ultra-low \\{NOx\\} industrial gas turbine combustors is reviewed. The principles of operation of single digit ultra-low \\{NOx\\} gas turbine combustion for industrial applications are outlined. The review shows the potential has been demonstrated by several investigators using different flame stabilizers for \\{NOx\\} to be reduced to 1 ppm at 1700 K, 2 ppm at 1800 K and 3–4 ppm at 1900 K with no influence of operating pressure and with a practical operating flame stability margin. Under these conditions it is shown that no thermal \\{NOx\\} should occur and all the \\{NOx\\} is formed by the prompt \\{NOx\\} mechanisms. The elimination of thermal \\{NOx\\} makes the \\{NOx\\} emissions independent of residence time or reference velocity and independent of pressure. Also there is no influence of air inlet temperature for the same flame temperature. Where legislation requires emissions to be as low as can be achieved, emissions below 4 ppm in production engines are current technology and this review shows the potential to get even lower than this in the future.

Propane Prices Influenced by Crude Oil and Natural Gas  

Gasoline and Diesel Fuel Update (EIA)

6 6 Notes: Propane prices have been high this year for several reasons. Propane usually follows crude oil prices more closely than natural gas prices. As crude oil prices rose beginning in 1999, propane has followed. In addition, some early cold weather this year put extra pressure on prices. However, more recently, the highly unusual surge in natural gas prices affected propane supply and drove propane prices up. Propane comes from two sources of supply: refineries and natural gas processing plants. The very high natural gas prices made it more economic for refineries to use the propane they normally produce and sell than to buy natural gas. The gas processing plants found it more economic to leave propane in the natural gas streams than to extract it for sale separately.

The effects of gas-to-oil rate in ultra low sulfur diesel hydrotreating  

Science Journals Connector (OSTI)

Hydrotreating has become a critical refining process as fuel sulfur specifications are tightened around the world. Recently, refiners in the United States have been learning how to optimize the performance of ultra low sulfur diesel (ulsd) hydrotreaters. The gas-to-oil feed rate ratio is known to be an important variable in this respect. It is well known that the gas-to-oil rate must be kept high enough to maintain the desired hydrogen partial pressure through the hydrotreating reactor, and to minimize the inhibiting effect of hydrogen sulfide. A lesser-known effect is the effect of gas-to-oil rate on the vapor–liquid equilibrium in the reactor. Changing the gas-to-oil rate alters the distribution of reactants between vapor and liquid in a way that changes the relative reaction rates of different sulfur compounds. This paper presents some pilot plant data and analysis showing this effect of phase equilibrium in deep diesel desulfurization. The effect can be modeled using the Frye–Mosby equation, which accounts for the effects of feed vaporization and phase equilibrium on the reaction rates of individual sulfur compounds in a trickle bed hydrotreater.

Scattering of Slow Neutrons from Propane Gas  

Science Journals Connector (OSTI)

Measurements of the partial differential neutron scattering cross sections for room-temperature propane gas are reported. These measurements were made at incident energies of 0.0101, 0.0254, 0.0736, and 0.102 ev at seven scattering angles between 16.3° and 84.7° using the Materials Testing Reactor phased chopper velocity selector. The data are converted to the scattering-law presentation and compared with three theoretical calculations: (a) The ideal gas, using an effective mass obtained from an average of the mass tensors for the three types of H atoms in propane, gives poor agreement. (b) The Krieger-Nelkin approximation, which includes the effect of zero-point vibrations, gives limited agreement for energy transfer less than 0.5kBT at intermediate momentum transfers. At large momentum transfers where vibrational effects become important it underestimates the cross section. (c) A modification of the Krieger-Nelkin theory that includes the effects of single-quantum transitions from the three lowest vibrational states gives better agreement. The discrepancies still present at large momentum and energy transfers are attributed to an uncertainty in the methyl-group barrier height for the three lowest energy modes, to the harmonic oscillator approximation for these modes, and to the approximate molecular orientation averaging used in the calculation.

Development of an ultra-safe, ultra-low emissions natural gas fueled school bus: Final report  

SciTech Connect

This report documents work conducted under Southwest Research Institute (SwRI) Project 03-6871, ``Development of an Ultra-Safe and Low-Emission Dedicated Alternative Fuel School Bus.`` The project was sponsored by the National Renewable Energy Laboratory (NREL) under Subcontract No. ZCF-5-13519-01. This report documents Phase 3 -- Integration and Phase 4 -- Demonstration and serves as the final report for this project. Phase 1 -- Systems Design and Phase 2 -- Prototype Hardware Development were documented in NREL publications TP-425-7609 and TP-425-2 1081, respectively. Several significant areas of work are summarized in this report. Integration of the engine technologies developed under Phase 2 into a production Deere 8.1-L, spark-ignition compressed natural gas engine is detailed, including information on the engine and control system modifications that were made. Federal Test Procedure (FTP) emissions results verifying the ultra-low emissions output of this engine are also included. The informal project goal of producing oxides of nitrogen (NO{sub x}) emissions less than or equal to 1.0 g/bhp-hr over the FTP heavy-duty engine cycle was attained. In addition, a test run that resulted in less than one half of the Ultra-Low Emissions Vehicle limit for NO{sub x} plus non-methane hydrocarbons was obtained. These results were for engine-out (no catalyst) emissions. Results using a catalyst produced very low formaldehyde emissions and virtually zero carbon monoxide and particulate matter emissions. Following these excellent results, a duplicate engine was assembled and integrated into the prototype ultra-safe school bus, the Envirobus 2000. Many of the new and modified subsystems developed during this project for the engine are considered strong candidates for inclusion into the production Deere 8.1-L gas engine in the near future.

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

SciTech Connect

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

Propane Outlook  

Gasoline and Diesel Fuel Update (EIA)

4 of 24 4 of 24 Notes: EIA expects lower residential propane prices this winter compared to the high prices seen last winter. As of now, it appears that propane inventories will be more than adequate going into this winter. Although inventories in the Midwest remain low, there is still time for the ample inventories in the Gulf Coast to make their way up into the Midwest before heating season begins in earnest. As always, the major uncertainties affecting demand this winter are the weather and the economy. Other uncertainties affecting the propane market this winter are crude oil and natural gas prices. If natural gas prices this winter are around what EIA expects them to be, we will likely see very little, if any, propane production shut-in at gas plants. However, as the current situation with the TET shows, there could be short

Propane Propane Transportation Fuel Basics - Propane July 30, 2013 - 4:31pm Addthis Photo of a man standing next to a propane fuel pump with a tank in the background. Propane, also known as liquefied petroleum gas (LPG or LP-gas), or autogas in Europe, is a high-energy alternative fuel. It has been used for decades to fuel light-duty and heavy-duty propane vehicles. Propane is a three-carbon alkane gas (C3H8). Stored under pressure inside a tank, propane turns into a colorless, odorless liquid. As pressure is released, the liquid propane vaporizes and turns into gas that is used for combustion. An odorant, ethyl mercaptan, is added for leak detection. Propane has a high octane rating and excellent properties for spark-ignited internal combustion engines. It is nontoxic and presents no threat to soil,

Physics with ultra-low energy antiprotons  

SciTech Connect

The experimental observation that all forms of matter experience the same gravitational acceleration is embodied in the weak equivalence principle of gravitational physics. However no experiment has tested this principle for particles of antimatter such as the antiproton or the antihydrogen atom. Clearly the question of whether antimatter is in compliance with weak equivalence is a fundamental experimental issue, which can best be addressed at an ultra-low energy antiproton facility. This paper addresses the issue. 20 refs.

Traceable low and ultra-low temperatures in The Netherlands  

Science Journals Connector (OSTI)

The basis for worldwide uniformity of low and ultra-low temperature measurements is provided by two international temperature scales, the International Temperature Scale of 1990 (ITS-90) for temperatures above 0.65 K and the Provisional Low Temperature Scale of 2000 (PLTS-2000) for temperatures in the range 0.9 mK to 1 K. Over the past 10 years, the thermometry research in the Netherlands provided substantial contributions to the definition, realization and dissemination of these scales. We first give an overview of the Dutch contributions to the ITS-90 realization: a) 3He and 4He vapour pressure thermometer range of the ITS-90, 0.65 K to 4 K (1997), b) 4He interpolating constant volume gas thermometry for the ITS-90 range 3 K to 24.5 K (2007) and c) cryogenic fixed points for the ITS-90 range 13.8 K to 273.16 K (2005). Then we highlight our work on 3He melting pressure thermometry from 10 mK to 1 K (2003) to support the dissemination of the PLTS-2000. Finally we present the current status of the Dutch calibration facilities and dissemination devices providing for traceable low and ultra-low temperatures for use in science and industry: a) the NMi-VSL cryogenic calibration facility for the range 0.65 K to 273.16 K and b) the SRD1000 superconductive reference devices for the range 10 mK to 1 K.

TIME-VARYING FLAME IONIZATION SENSING APPLIED TO NATURAL GAS AND PROPANE BLENDS IN A PRESSURIZED LEAN PREMIXED (LPM) COMBUSTOR  

SciTech Connect

In-situ monitoring of combustion phenomena is a critical need for optimal operation and control of advanced gas turbine combustion systems. The concept described in this paper is based on naturally occurring flame ionization processes that accompany the combustion of hydrocarbon fuels. Previous work has shown that flame ionization techniques may be applied to detect flashback, lean blowout, and some aspects of thermo-acoustic combustion instabilities. Previous work has focused on application of DC electric fields. By application of time-varying electric fields, significant improvements to sensor capabilities have been observed. These data have been collected in a lean premixed combustion test rig operating at 0.51-0.76 MPa (5-7.5 atm) with air preheated to 588 K (600°F). Five percent of the total fuel flow is injected through the centerbody tip as a diffusion pilot. The fuel composition is varied independently by blending approximately 5% (volume) propane with the pipeline natural gas. The reference velocity through the premixing annulus is kept constant for all conditions at a nominal value of 70 m/s. The fuel-air equivalence ratio is varied independently from 0.46 – 0.58. Relative to the DC field version, the time-varying combustion control and diagnostic sensor (TV-CCADS) shows a significant improvement in the correlation between the measured flame ionization current and local fuel-air equivalence ratio. In testing with different fuel compositions, the triangle wave data show the most distinct change in flame ionization current in response to an increase in propane content. Continued development of this sensor technology will improve the capability to control advanced gas turbine combustion systems, and help address issues associated with variations in fuel supplies.

Optical interferometry at ultra low temperatures  

SciTech Connect

We have developed optical, interferometric methods for investigations of interfaces at ultra low temperatures. In our scheme conventional optical windows are avoided: laser illumination (He-Ne) is guided into the cryostat via a single-mode optical fiber and images are taken using a CCD sensor mounted inside the 4-K vacuum can. A real-time video camera has been successfully used in investigations of superfluid {sup 3}He down to 0.6 mK whereas a slow-scan camera has been employed for optimal contrast in low-intensity imaging of liquid/solid interfaces (reflection coefficient {approximately}10{sup -6}). The investigated topics include (1) superfluid {sup 3}He surface in rotation and during rapid deceleration, (2) hydrodynamics of thin superfluid {sup 3}He layers, (3) superfluid/solid interface in {sup 4}He, and (4) wetting of superfluid {sup 4}He by normal {sup 3}He in phase separated mixtures. A vertical resolution of 10 nm and even below has been achieved in these studies.

Ultra-Low NOx Advanced Vortex Combustor  

SciTech Connect

An ultra lean-premixed Advanced Vortex Combustor (AVC) has been developed and tested. The natural gas fueled AVC was tested at the U.S. Department of Energy’s National Energy Technology Laboratory (USDOE NETL) test facility in Morgantown (WV). All testing was performed at elevated pressures and inlet temperatures and at lean fuel-air ratios representative of industrial gas turbines. The improved AVC design exhibited simultaneous NOx/CO/UHC emissions of 4/4/0 ppmv (all emissions are at 15% O2 dry). The design also achieved less than 3 ppmv NOx with combustion efficiencies in excess of 99.5%. The design demonstrated tremendous acoustic dynamic stability over a wide range of operating conditions which potentially makes this approach significantly more attractive than other lean premixed combustion approaches. In addition, a pressure drop of 1.75% was measured which is significantly lower than conventional gas turbine combustors. Potentially, this lower pressure drop characteristic of the AVC concept translates into overall gas turbine cycle efficiency improvements of up to one full percentage point. The relatively high velocities and low pressure drops achievable with this technology make the AVC approach an attractive alternative for syngas fuel applications.

U.S. Propane Total Stocks

9 9 Notes: U.S. inventories of propane benefited from a late pre-season build that pushed inventories to over 65 million barrels by early November 2000, the second highest peak pre-heating season level since 1986. Although propane inventories were expected to remain within the normal range for the duration of the 2000-01 heating season, cold weather in November and December, along with recently high natural gas prices that discouraged propane production from gas processing, resulted in stocks falling below the normal range by the end of December. However, if the weather remains seasonally normal, and the recent decline in natural gas prices holds, EIA expects the propane inventory drawdown to slow. This is reflected in the data for January 19, which showed a draw of only 2.1 million barrels, compared to more than twice that

Welding of HSLA-100 steel using ultra low carbon bainitic weld metal to eliminate preheating  

SciTech Connect

Advanced high strength steels such as the Navy`s HSLA-100 and HSLA-80 contain sufficiently low carbon levels to be weldable without preheating. Unfortunately, commercial filler metals specifically designed to weld these steels without costly preheating have not yet been developed. The objective of this paper is to show that the Navy`s advanced steels can be welded by gas metal-arc (GMAW) and gas tungsten-arc welding (GTAW) without preheating by using filler metal compositions that produce weld metal with an ultra-low carbon bainitic (ULCB) microstructure. Filler metals were fabricated from vacuum induction melted (VIM) ingots containing ultra-low levels of C, O and N. HSLA-100 plate and plate from the VIM ingots were welded by both GMAW and GTAW with Ar-5% CO{sub 2} shielding gas using welding conditions to achieve cooling times from 800 to 500 C (t{sub 8-5}) from 35 to 14 sec. Weld metal tensile, hardness and CVN impact toughness testing as well as microstructural studies using transmission electron microscopy were conducted. The ULCB weld metal was relatively insensitive to cooling rate, resulting in good strength and toughness values over a wide range of t{sub 8-5} cooling times. Filler metal compositions which met the mechanical property requirements for HSLA-100, HSLA-80 and HSLA-65 weld metal were developed.

Propane: A Mid-heating Season Assessment  

Gasoline and Diesel Fuel Update (EIA)

9, 2001 9, 2001 Propane - A Mid-Heating Season Assessment by David Hinton and Alice Lippert, Petroleum Division, Office of Oil and Gas, Energy Information Administration In early October 2000, the Energy Information Administration (EIA) forecast that heating fuel markets would be expected to start the season with much higher prices and lower inventories than in recent years. While this assessment was true for both the heating oil and natural gas markets, propane markets actually began the season with adequate supplies but with high prices. Since EIA's forecast, propane inventories have plunged nearly 20 million barrels from their peak during the first half of the 2000-01 heating season while propane prices have continued to soar even higher than expected during this same period. This report will analyze some

High propane recovery process, Delpro{trademark} saves energy  

SciTech Connect

There are several technologies for recovering propane from natural gas. These include simple refrigeration which typically operate at {minus}10 F for dewpoint control operations or {minus}40 F for propane recovery. Turbo-expander systems are well established for levels of propane recovery. Other processes include lean oil systems (or hydrocarbon liquid as in the Mehra process) for recovering propane up to about the 95% recovery level. Delta Hudson has developed a new process which recovers propane from natural gas using a turbo-expander. This new process has the trade name DELPRO{trademark} and has been patented in the United States, Canada and several other countries. The advantages of the DELPRO{trademark} high recovery process are as follows: Propane recovery up to 99% is economically achievable; Simple flow scheme; Power consumption is reduced by up to 15% compared to competing processes for the same propane recovery level; For the same power consumption as used by competing processes, significantly higher propane recovery levels are achieved; and DELPRO{trademark} can be adapted to ethane recovery. In this mode, the process has the advantage that it rejects carbon dioxide to a greater extent than other processes. This reduces, or in some cases, eliminates subsequent treating requirements.

Ultra-low field nuclear magnetic resonance and magnetic resonance imaging to discriminate and identify materials  

DOE Patents (OSTI)

An ultra-low magnetic field NMR system can non-invasively examine containers. Database matching techniques can then identify hazardous materials within the containers. Ultra-low field NMR systems are ideal for this purpose because they do not require large powerful magnets and because they can examine materials enclosed in conductive shells such as lead shells. The NMR examination technique can be combined with ultra-low field NMR imaging, where an NMR image is obtained and analyzed to identify target volumes. Spatial sensitivity encoding can also be used to identify target volumes. After the target volumes are identified the NMR measurement technique can be used to identify their contents.

Adsorptive separation of propylene-propane mixtures  

SciTech Connect

The separation of propylene-propane mixtures is of great commercial importance and is carried out by fractional distillation. It is claimed to be the most energy-intensive distillation practiced in the United States. The purpose of this paper is to describe experimental work that suggests a practical alternative to distillation for separating the C[sub 3] hydrocarbons: adsorption. As studied, the process involves three adsorptive steps: initial separation with molecular sieves with heavy dilution with an inert gas; separation of propylene and propane separately from the inert gas, using activated carbon; and drying of the product streams with any of several available desiccants. The research information presented here deals with the initial step and includes both equilibrium and kinetic data. Isotherms are provided for propylene and propane adsorbed on three zeolites, activated alumina, silica gel, and coconut-based activated carbon. Breakthrough data are provided for both adsorption and regeneration steps for the zeolites, which were found to be superior to the other adsorbents for breakthrough separations. A flow diagram for the complete proposed process is included.

Development of an ultra-low temperature multi-frequency ESR apparatus  

Science Journals Connector (OSTI)

An ultra-low temperature multi-frequency electron spin resonance (ESR) apparatus has been developed for use at a temperature down to about 200 mK by utilizing a 3He-4He compact dilution refrigerator and a vector network analyzer. The microwave frequency can be varied between 30 GHz and 700 GHz almost continuously. Either of the two kinds of copper blocks with a sample holder for typical two configurations, namely Faraday and Voigt configurations, is attached to a stainless steel block neighboring to a mixing chamber which provides ultra-low temperarures down to 160 mK. A magnetic field up to 16 T is produced with a superconducting magnet (14 T at 4.2 K and 16 T at 2.2 K). Thus, we have a potential to perform ESR measurements in a very wide frequency-field window at ultra-low temperatures.

Balloon observations of ultra-low-frequency waves in the electric field above the South Pole  

SciTech Connect

The physics of ultra-low-frequency waves in the magnetosphere, near the cusp and in the polar cap, is important because this region is one where ultra-low-frequency wave energy from the magnetopause can most easily enter the magnetosphere. During the 1985-1986 South Pole balloon campaign, eight stratospheric balloon payloads were launched from Amundsen-Scott Station, South Geographic Pole, Antarctica, to record data on ultra-low-frequency waves. The payloads were instrumented with three-axis double-probe electric field detectors and X-ray scintillation counters. This paper concentrates on the third flight of this series, which was launched at 2205 universal time on 21 December 1985. Good data were received from the payload until the transmitter failed at 0342 universal time on 22 December. During most of the four hours that the balloon was afloat, an intense ultra-low-frequency wave event was in progress. The electric-field data from this period have been examined in detail and compared with magnetic field data, obtained with ground-based fluxgate and induction magnetometers to determine the characteristics of the waves. After float was reached, the electric-field data in figure 1 show large-amplitude, quasi-periodic fluctuations suggesting the presence of intense ultra-low-frequency wave activity. In conclusion, the electric-field signature observed from flight 3 appears to have been essentially an electrostatic event or possibly a short-wavelength hydromagnetic wave with a varying and interesting polarization character. The authors are continuing the analysis of the data to determine the source of the observed ultra-low-frequency waves.

Titan's Prolific Propane: The Cassini CIRS Perspective  

E-Print Network (OSTI)

In this paper we select large spectral averages of data from the Cassini Composite Infrared Spectrometer (CIRS) obtained in limb-viewing mode at low latitudes (30S--30N), greatly increasing the path length and hence signal-to-noise ratio for optically thin trace species such as propane. By modeling and subtracting the emissions of other gas species, we demonstrate that at least six infrared bands of propane are detected by CIRS, including two not previously identified in Titan spectra. Using a new line list for the range 1300-1400cm -1, along with an existing GEISA list, we retrieve propane abundances from two bands at 748 and 1376 cm-1. At 748 cm-1 we retrieve 4.2 +/- 0.5 x 10(-7) (1-sigma error) at 2 mbar, in good agreement with previous studies, although lack of hotbands in the present spectral atlas remains a problem. We also determine 5.7 +/- 0.8 x 10(-7) at 2 mbar from the 1376 cm-1 band - a value that is probably affected by systematic errors including continuum gradients due to haze and also an imperf...

Ultra-low temperature laboratory freezers (ULTs) are some of the most energy-intensive pieces of equipment in a scientific research laboratory, yet there are several barriers to user acceptance and adoption of high-efficiency ULTs. One significant barrier is a relative lack of information on ULT efficiency to help purchasers make informed decisions with respect to efficient products.

Antiproton Annihilations in Propane  

Science Journals Connector (OSTI)

An experiment to study the p¯ annihilation process at 1.05 Bev/c was performed with the Lawrence Radiation Laboratory 30-in. propane bubble chamber. It was observed that the K-meson production in annihilation events rises sharply with the increase in energy, namely from 4±1% for annihilations at or near "rest" to 8±1%. On the other hand, the pion multiplicity was not observed to increase appreciably with the increase of available energy. We have found a pion multiplicity of 5.0±0.2. These numbers are discussed in this paper and compared with existing models for the p¯ annihilation process. It is pointed out that with further increase in bombarding energy different models may differ appreciably in the above quantities.We have observed a p¯-H annihilation cross section of 51±10 mb and a p¯-C annihilation cross section of 368±60 mb at a p¯ momentum of 1.05 Bev/c. Crude determinations of the p¯ charge-exchange process—which turns out to be forward peaked— and of p¯ inelastic-scattering events leading to pion production are also discussed.

Integrated production/use of ultra low-ash coal, premium liquids and clean char  

SciTech Connect

This integrated, multi-product approach for utilizing Illinois coal starts with the production of ultra low-ash coal and then converts it to high-vale, coal-derived, products. The ultra low-ash coal is produced by solubilizing coal in a phenolic solvent under ChemCoal{trademark} process conditions, separating the coal solution from insoluble ash, and then precipitating the clean coal by dilution of the solvent with methanol. Two major products, liquids and low-ash char, are then produced by mild gasification of the low-ash coal. The low ash-char is further upgraded to activated char, and/or an oxidized activated char which has catalytic properties. Characterization of products at each stage is part of this project.

Specifications of the octupole magnets required for the ATF2 ultra-low ß* lattice  

SciTech Connect

The Accelerator Test Facility 2 (ATF2) aims to test the novel chromaticity correction for higher chromaticity lattices as the one of CLIC. To this end the ATF2 ultra-low ß* lattice is designed to vertically focus the beam at the focal point or usually referred to as interaction point (IP), down to 23 nm. However when the measured multipole components of the ATF2 magnets are considered in the simulations, the evaluated spot sizes at the IP are well above the design value. The designed spot size is effectively recovered by inserting a pair of octupole magnets. In this note we address the technical specifications required for these octupole magnets.

The QDs are fabricated under optimized process conditions and have ultra-low density in the 10{sup 6} cm{sup ?2} regime. At low excitation power the optical emission of single QDs exhibit sharp excitonic lines, which are attributed to the recombination of excitonic and biexcitonic states. High excitation power measurements reveal surprisingly broad emission lines from at least six QD shell states.

On November 8, 2005, the Environmental Protection Agency (EPA) Administrator signed a direct final rule that will shift the retail compliance date for offering ultra-low sulfur diesel (ULSD) for highway use from September 1, 2006, to October 15, 2006. The change will allow more time for retail outlets and terminals to comply with the new 15 parts per million (ppm) sulfur standard, providing time for entities in the diesel fuel distribution system to flush higher sulfur fuel out of the system during the transition. Terminals will have until September 1, 2006, to complete their transitions to ULSD. The previous deadline was July 15, 2006.

Development of a dedicated ethanol ultra-low emission vehicle (ULEV) -- Phase 2 report  

SciTech Connect

The objective of this 3.5-year project is to develop a commercially competitive vehicle powered by ethanol (or an ethanol blend) that can meet California`s ultra-low emission vehicle (ULEV) standards and equivalent corporate average fuel economy (CAFE) energy efficiency for a light-duty passenger car application. The definition of commercially competitive is independent of fuel cost, but does include technical requirements for competitive power, performance, refueling times, vehicle range, driveability, fuel handling safety, and overall emissions performance. This report summarizes the second phase of this project, which lasted 12 months. This report documents two baseline vehicles, the engine modifications made to the original equipment manufacturer (OEM) engines, advanced aftertreatment testing, and various fuel tests to evaluate the flammability, lubricity, and material compatibility of the ethanol fuel blends.

GRABGAM: A Gamma Analysis Code for Ultra-Low-Level HPGe SPECTRA  

SciTech Connect

The GRABGAM code has been developed for analysis of ultra-low-level HPGe gamma spectra. The code employs three different size filters for the peak search, where the largest filter provides best sensitivity for identifying low-level peaks and the smallest filter has the best resolution for distinguishing peaks within a multiplet. GRABGAM basically generates an integral probability F-function for each singlet or multiplet peak analysis, bypassing the usual peak fitting analysis for a differential f-function probability model. Because F is defined by the peak data, statistical limitations for peak fitting are avoided; however, the F-function does provide generic values for peak centroid, full width at half maximum, and tail that are consistent with a Gaussian formalism. GRABGAM has successfully analyzed over 10,000 customer samples, and it interfaces with a variety of supplementary codes for deriving detector efficiencies, backgrounds, and quality checks.

New limits were set for WIMPs with mass between 3-6 GeV. The prospects of the realization of full-scale experiments are discussed. This detector technique makes the unexplored sub-keV energy window accessible for new neutrino and dark matter experiments.

Electrical activation and spin coherence of ultra low doseantimony implants in silicon  

SciTech Connect

We implanted ultra low doses (0.2 to 2 x 10{sup 11} cm{sup -2}) of Sb ions into isotopically enriched {sup 28}Si, and probed electrical activation and electron spin relaxation after rapid thermal annealing. Strong segregation of dopants towards both Si{sub 3}N{sub 4} and SiO{sub 2} interfaces limits electrical activation. Pulsed Electron Spin Resonance shows that spin echo decay is sensitive to the dopant profiles, and the interface quality. A spin decoherence time, T{sub 2}, of 1.5 ms is found for profiles peaking 25 nm below a Si/SiO{sub 2} interface, increasing to 2.1 ms when the surface is passivated with hydrogen. These measurements provide benchmark data for the development of devices in which quantum information is encoded in donor electron spins.

Low energy conversion electron detection in superfluid He3 at ultra-low temperature  

E-Print Network (OSTI)

We report on the first results of the MACHe3 (MAtrix of Cells of Helium 3) prototype experiment concerning the measurement of low energy conversion electrons at ultra-low temperature. For the first time, the feasibility of the detection of low energy electrons is demonstrated in superfluid He3-B cooled down to 100 microK. Low energy electrons at 7.3 keV coming from the K shell conversion of the 14.4 keV nuclear transition of a low activity Co57 source are detected, opening the possibility to use a He3-based detector for the detection of Weakly Interacting Massive Particles (WIMPs) which are expected to release an amount of energy higher-bounded by 5.6 keV.

Ultra-low-temperature neutron diffraction. Final report, July 1, 1983-June 30, 1985. Final report  

SciTech Connect

An ultra-low-temperature neutron diffraction facility has been constructed at Argonne National Laboratory. The initial and primary purpose of this facility is to study nuclear magnetic ordering phenomenon. Magnetic structure information is commonly recognized as being fundamental to the progress in theoretical and experimental efforts in the field of magnetism. We have initiated study of the nuclear spin in solid /sup 3/He and in metals. In /sup 3/He the nuclear spins order at 1.1 mK. Structure information for neutron diffraction would contribute significantly to this problem of nuclear magnetism. Despite substantial experimental difficulties, careful evaluation suggests that examination of the nuclear structure in this unique quantum crystal is indeed feasible by neutron diffraction. Substantial progress has been made in growing single crystals of /sup 3/He and establishing its temperature in the presence of a neutron flux. We have also initiated investigation of nuclear ordering in copper and PrCu/sub 6/.

Construction of a Dilution Refrigerator Based Ultra-Low Temperature Scanning Tunneling Microscope  

Science Journals Connector (OSTI)

We constructed a dilution refrigerator based ultra-low temperature scanning tunneling microscope (ULT-STM) which works at temperatures down to 20 mK, in magnetic fields up to 6 T and in ultrahigh vacuum (UHV). One can load samples/tips, which are prepared in a UHV chamber, to an STM head maintaining the low temperature and UHV conditions. After then they can be cooled back to the base temperature in several hours. We report results of a test measurement on a superconducting NbSe2 sample as well as recent STM/STS studies on graphite samples such as observations of the Landau quantization and visualization of the possible localized states in magnetic fields.

An ultra low noise AC beam transformer for deceleration and diagnostics of low intensity beams  

E-Print Network (OSTI)

The design of a broad band ultra-low noise ferrite loaded AC beam transformer is presented. It is designed for use in the CERN Antiproton Decelerator (AD), where beams of a few 107 charges must be decelerated from 3.5 GeV/c to 100 MeV/c. It is used in the RF beam-phase loop, and for intensity and bunch shape measurements during deceleration. When the beam is debunched for cooling on magnetic flat tops, the pick-up is used for measurements of intensity and momentum distribution by means of longitudinal Schottky scans. When used as Schottky pick-up, the signal to noise ratio should be better by about 40 dB than the existing stripline based longitudinal Schottky pick-up. The integrated design of pick-up and associated low-noise amplifier is presented. The achieved noise performance of a few from 1 to 3 MHz is obtained by attaching a low-noise, high-impedance silicon JFET (junction field effect transistor) amplifier to a high-Q resonant ferrite loaded cavity, and then eliminating the resonant response by low-nois...

CMOS preamplifier with high linearity and ultra low noise for x-ray spectroscopy  

SciTech Connect

We present an ultra low noise charge preamplifier suitable for small capacitance (200M), low leakage current solid state detectors. A self adaptive bias circuit for the MOS feedback device establishes the static feedback resistance in the G{Omega} range while tracking the threshold variations and power supply and temperature fluctuations. The linearity of the gain versus input charge has been improved by means of a voltage divider between the output of the charge-sensitive amplifier and the source of the feedback transistor. With the preamplifier alone, we measure a room-temperature equivalent noise charge (ENC) of 9 e{sup -} rms at 12 usec shaping time. When coupled to a cooled detector a FWHM of 130 eV is obtained at 2.4 usec shaping, corresponding to an ENC of 16 e{sup -} rms. This is the best reported resolution obtained with a CMOS preamplifier. The circuit has good linearity (< 0.2%) up to 1.8 W. Since the preamplifier`s ENC is limited by flicker noise, we fabricated the circuit in two 1.2um CMOS technologies. Device measurements allow us to compare the 1/f noise behavior of each foundry. In addition to the preamplifiers, a 1 us shaper and a 50{Omega} output driver are included on the die.

Advanced furnace air staging and burner modifications for ultra-low NOx firing systems  

SciTech Connect

Overfire air is an effective means to reduce NOx emissions from coal fired furnaces. The current range of overfire air usage on wall-fired boilers in the US is in the range of 10 to 20%. In most cases this is enough to achieve current Title IV NOx reduction requirements. Future applications are likely to go beyond 20% Overfire Air to reduce NOx further for lower investment and operating costs of SCR retrofits. Summer ozone reduction requires NOx emissions of 0.15 lb/MBtu. Currently, industry is exploring the conditions under which this goal is attainable. The paper discussed the approach to achieve ultra-low NOx emissions by using advanced furnace air staging. It describes the unique approach of redesigning the burner to maintain low NOx burner performance when the overfire air system is added or increased in capacity. The impact on furnace corrosion and unburned carbon losses are presented. A case study is used to show the effects of overfire air both on emissions and unburned carbon.

Development of a dedicated ethanol ultra-low emission vehicle (ULEV): Final report  

SciTech Connect

The objective of this project was to develop a commercially competitive vehicle powered by ethanol (or an ethanol blend) that can meet California`s ultra-low emission vehicle (ULEV) standards and equivalent corporate average fuel economy (CAFE) energy efficiency for a light-duty passenger car application. The definition of commercially competitive is independent of fuel cost, but does include technical requirements for competitive power, performance, refueling times, vehicle range, driveability, fuel handling safety, and overall emissions performance. This report summarizes the fourth and final phase of this project, and also the overall project. The focus of this report is the technology used to develop a dedicated ethanol-fueled ULEV, and the emissions results documenting ULV performance. Some of the details for the control system and hardware changes are presented in two appendices that are SAE papers. The demonstrator vehicle has a number of advanced technological features, but it is currently configured with standard original equipment manufacturer (OEM) under-engine catalysts. Close-coupled catalysts would improve emissions results further, but no close-coupled catalysts were available for this testing. Recently, close-coupled catalysts were obtained, but installation and testing will be performed in the future. This report also briefly summarizes work in several other related areas that supported the demonstrator vehicle work.

Development of a dedicated ethanol ultra-low emission vehicle (ULEV) system design

The objective of this 3.5 year project is to develop a commercially competitive vehicle powered by ethanol (or ethanol blend) that can meet California`s ultra-low emission vehicle (ULEV) standards and equivalent corporate average fuel economy (CAFE) energy efficiency for a light-duty passenger car application. The definition of commercially competitive is independent of fuel cost, but does include technical requirements for competitive power, performance, refueling times, vehicle range, driveability, fuel handling safety, and overall emissions performance. This report summarizes a system design study completed after six months of effort on this project. The design study resulted in recommendations for ethanol-fuel blends that shall be tested for engine low-temperature cold-start performance and other criteria. The study also describes three changes to the engine, and two other changes to the vehicle to improve low-temperature starting, efficiency, and emissions. The three engine changes are to increase the compression ratio, to replace the standard fuel injectors with fine spray injectors, and to replace the powertrain controller. The two other vehicle changes involve the fuel tank and the aftertreatment system. The fuel tank will likely need to be replaced to reduce evaporative emissions. In addition to changes in the main catalyst, supplemental aftertreatment systems will be analyzed to reduce emissions before the main catalyst reaches operating temperature.

SQUID gradiometer for ultra-low temperature magnetic micro-calorimeter  

Science Journals Connector (OSTI)

First-order integrated planar SQUID gradiometers with pick-up loops of 40 µm in diameter and a baseline of 200 µm were designed specially for the readout of signals from magnetic micro-calorimeters. The SQUID has to operate in magnetic fields up to 5 mT and at temperatures down to 7 mK. The design is a first step to develop a multi-pixel x-ray detector, which can be used in high-resolution x-ray fluorescence analysis. Chip coils with a heater switch produce a magnetic field up to a few millitesla in persistent current mode. A SQUID-array amplifier was used to readout the signal of the SQUID gradiometer. The intrinsic noise of the gradiometer at 4.2 K is lower than 1 ??0 Hz?1/2. The SQUID can withstand external magnetic fields up to 7 mT without losing its performance. The results of a test with the SQUID gradiometer at ultra low temperatures are reported.

Propane vehicles : status, challenges, and opportunities.  

SciTech Connect

Propane as an auto fuel has a high octane value and has key properties required for spark-ignited internal combustion engines. To operate a vehicle on propane as either a dedicated fuel or bi-fuel (i.e., switching between gasoline and propane) vehicle, only a few modifications must be made to the engine. Until recently propane vehicles have commonly used a vapor pressure system that was somewhat similar to a carburetion system, wherein the propane would be vaporized and mixed with combustion air in the intake plenum of the engine. This leads to lower efficiency as more air, rather than fuel, is inducted into the cylinder for combustion (Myers 2009). A newer liquid injection system has become available that injects propane directly into the cylinder, resulting in no mixing penalty because air is not diluted with the gaseous fuel in the intake manifold. Use of a direct propane injection system will improve engine efficiency (Gupta 2009). Other systems include the sequential multi-port fuel injection system and a bi-fuel 'hybrid' sequential propane injection system. Carbureted systems remain in use but mostly for non-road applications. In the United States a closed-loop system is used in after-market conversions. This system incorporates an electronic sensor that provides constant feedback to the fuel controller to allow it to measure precisely the proper air/fuel ratio. A complete conversion system includes a fuel controller, pressure regulator valves, fuel injectors, electronics, fuel tank, and software. A slight power loss is expected in conversion to a vapor pressure system, but power can still be optimized with vehicle modifications of such items as the air/fuel mixture and compression ratios. Cold start issues are eliminated for vapor pressure systems since the air/fuel mixture is gaseous. In light-duty propane vehicles, the fuel tank is typically mounted in the trunk; for medium- and heavy-duty vans and trucks, the tank is located under the body of the vehicle. Propane tanks add weight to a vehicle and can slightly increase the consumption of fuel. On a gallon-to-gallon basis, the energy content of propane is 73% that of gasoline, thus requiring more propane fuel to travel an equivalent distance, even in an optimized engine (EERE 2009b).

Performance and cost of automotive fuel cell systems with ultra-low platinum loadings.  

SciTech Connect

An automotive polymer-electrolyte fuel cell (PEFC) system with ultra-low platinum loading (0.15 mg-Pt cm{sup -2}) has been analyzed to determine the relationship between its design-point efficiency and the system efficiency at part loads, efficiency over drive cycles, stack and system costs, and heat rejection. The membrane electrode assemblies in the reference PEFC stack use nanostructured, thin-film ternary catalysts supported on organic whiskers and a modified perfluorosulfonic acid membrane. The analyses show that the stack Pt content can be reduced by 50% and the projected high-volume manufacturing cost by >45% for the stack and by 25% for the system, if the design-point system efficiency is lowered from 50% to 40%. The resulting penalties in performance are a <1% reduction in the system peak efficiency; a 2-4% decrease in the system efficiency on the urban, highway, and LA92 drive cycles; and a 6.3% decrease in the fuel economy of the modeled hybrid fuel-cell vehicle on the combined cycle used by EPA for emission and fuel economy certification. The stack heat load, however, increases by 50% at full power (80 kW{sub e}) but by only 23% at the continuous power (61.5 kW{sub e}) needed to propel the vehicle on a 6.5% grade at 55 mph. The reduced platinum and system cost advantages of further lowering the design-point efficiency from 40% to 35% are marginal. The analyses indicate that thermal management in the lower efficiency systems is very challenging and that the radiator becomes bulky if the stack temperature cannot be allowed to increase to 90-95 C under driving conditions where heat rejection is difficult.

A pilot reactor study to determine operational factors of the commercial hydrodesulphurization (HDS) catalyst to produce ultra-low sulphur diesel (ULSD)  

Science Journals Connector (OSTI)

Abstract A pilot plant test was carried out using a catalyst from the refinery hydrotreater unit to process blend feed of 70 vol% Light Gas Oil – LGO & 30 vol% hydrotreated Gas Oil – HDT GO to produce 8 ppm ultra-low sulphur diesel (ULSD) product. The impact of changes in process conditions have been studied for catalyst deactivation rate and hydrogen consumption. Test results shown that refinery unit can process such blend feed to reach 8 ppm sulphur product by an increase of the reactor bed temperature. However due to higher aromatic content in the blend feed as compare to reference feed LGO, moderate increase in hydrogen consumption was also observed. Catalyst performance was evaluated at 55/42/32 bar hydrogen partial pressure (PPH2) to determine catalyst deactivation rate and hydrogen consumption, targeting ULSD product. A decrease of PPH2 from 52 bar (which is current operating condition) to 32 bar resulted in reduction of H2 consumption but also shows decrease of catalyst cycle length due to higher deactivation rate. Pilot plant test shows that by contriving computational methods and analysis techniques for hydrogen balance & catalyst deactivation rate from the pilot plant test data, it becomes possible to predict catalyst performance in commercial unit.

Prospects for ultra-low-energy muon beam at J-PARC  

Science Journals Connector (OSTI)

Spin-polarized ultra-low-energy muons (LE-?+) with energies in eV–keV range provide a sensitive magnetic microprobe for studying near-surface regions, thin-film samples, multi-layered materials, etc. with depth resolution on a nanometer scale. Yet, worldwide there is currently only one (continuous) source of low-energy muons that is routinely used for such measurements. A pulsed source with many unique parameters (such as low-energy resolution of ?14 eV, time resolution of 7 ns, low background and spot size of just 4 mm) has been demonstrated at RIKEN-RAL muon facility at ISIS, but its use is limited by a rate of only 15 ?+/s. The method of low-energy muon generation is based on a resonant laser ionization of thermal energy muonium and is ideally suited for a pulsed muon source such as J-PARC MUSE, since the pulse structure of the generated LE-?+ is then determined by the laser pulse duration. The double pulse structure of the surface muon beam can, therefore, be converted to a single LE-?+ pulse with a pulse duration that can be as short as 1 ns and can also be externally triggered. J-PARC is designed to deliver surface muon beam with rates up to 4×108 ?+/s and direct transfer of the same laser technology from RIKEN-RAL to J-PARC would provide a LE-?+ beam with rates comparable to the existing continuous LE-?+ beam at PSI (?104 LE-?+/s). An improvement in the laser pulse energy could lead to a higher efficiency and higher rates up to 106 LE-?+/s may be possible. Construction of an intense LE-?+ beamline at J-PARC MUSE would open up the possibility to do routine depth-dependent ?SR measurements with thin film samples, with the muon implantation depth as low as 1 nm. In addition, the unique capability to synchronize the muon implantation with the sample excitation (e.g. by another laser or rf pulse) would allow to carry out pump-probe-type experiments.

State Heating Oil & Propane Program. Final report 1997/98 heating season  

SciTech Connect

The following is a summary report of the New Hampshire Governor`s Office of Energy and Community Services (ECS) participation in the State Heating Oil and Propane Program (SHOPP) for the 1997/98 heating season. SHOPP is a cooperative effort, linking energy offices in East Coast and Midwest states, with the Department of Energy (DOE), Energy Information Administration (EIA) for the purpose of collecting retail price data for heating oil and propane. The program is funded by the participating state with a matching grant from DOE. SHOPP was initiated in response to congressional inquires into supply difficulties and price spikes of heating oil and propane associated with the winter of 1989/90. This is important to New Hampshire because heating oil controls over 55% of the residential heating market statewide. Propane controls 10% of the heating market statewide and is widely used for water heating and cooking in areas of the state where natural gas is not available. Lower installation cost, convenience, lower operating costs compared to electricity, and its perception as a clean heating fuel have all worked to increase the popularity of propane in New Hampshire and should continue to do so in the future. Any disruption in supply of these heating fuels to New Hampshire could cause prices to skyrocket and leave many residents in the cold.

Propane-Fueled Vehicle Basics | Department of Energy  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Propane-Fueled Vehicle Basics Propane-Fueled Vehicle Basics Propane-Fueled Vehicle Basics August 20, 2013 - 9:16am Addthis There are more than 270,000 on-road propane vehicles in the United States and more than 10 million worldwide. Many are used in fleets, including light- and heavy-duty trucks, buses, taxicabs, police cars, and rental and delivery vehicles. Compared with vehicles fueled with conventional diesel and gasoline, propane vehicles can produce significantly fewer harmful emissions. The availability of new light-duty original equipment manufacturer propane vehicles has declined in recent years. However, certified installers can economically and reliably retrofit many light-duty vehicles for propane operation. Propane engines and fueling systems are also available for heavy-duty vehicles such as school buses and street sweepers.

Fuel cells—I. Propane on palladium catalyst  

Science Journals Connector (OSTI)

For the reaction at low temperatures of a gaseous hydrocarbon as a fuel gas at a negative electrode in a fuel cell, the choice of a suitable catalyst is of the first importance. In the present study, catalysts consisting of palladium reduced by hydrogen and palladium reduced by formate, supported on four types of porous skeleton disks (thin nickel, thick nickel and two types of carbon), were examined. In many cases, the electrodes were given a water-proofing treatment. The specific fuel cell used involved the prepared fuel electrode using gaseous propane, 30% KOH solution, a carbon-black air electrode and a temperature of 5O°C We attempt to distinguish the behaviour of propane from that due to hydrogen contained in the electrode, mainly on the basis of the relationship between (a) electrode preparation and treatment and (b) the open-circuit potential behaviour of the fuel electrode. The repetition of small current discharges resulted in open-circuit potentials reaching steady high potentials and in electrodes exhibiting comparatively good dischargeabilities.

An analysis of US propane markets, winter 1996-1997  

SciTech Connect

In late summer 1996, in response to relatively low inventory levels and tight world oil markets, prices for crude oil, natural gas, and products derived from both began to increase rapidly ahead of the winter heating season. Various government and private sector forecasts indicated the potential for supply shortfalls and sharp price increases, especially in the event of unusually severe winter weather. Following a rapid runup in gasoline prices in the spring of 1996, public concerns were mounting about a possibly similar situation in heating fuels, with potentially more serious consequences. In response to these concerns, the Energy Information Administration (EIA) participated in numerous briefings and meetings with Executive Branch officials, Congressional committee members and staff, State Energy Offices, and consumers. EIA instituted a coordinated series of actions to closely monitor the situation and inform the public. This study constitutes one of those actions: an examination of propane supply, demand, and price developments and trends.

An Estimate of the Signal-to-Noise Ratio in Nuclear Magnetic Resonance Measurements at Ultra-Low Temperatures  

Science Journals Connector (OSTI)

The signal-to-noise ratios for nuclear magnetic resonance (NMR) measurements by the Continuous Wave (CW) and the Pulsed NMR techniques are compared for applications at ultra-low temperatures. This comparison is made at 0.1, 1 and 10 mK as a function of the energy dissipation. The resonance signal is to be detected by a conventional method using a receiver r-f coil or by using a SQUID detector and the relative merits of the two detection methods are discussed for both the CW and the Pulse techniques. For the CW NMR, the SQUID detection method is found to have an advantage over the conventional method except at a relatively high applied DC field. For the pulsed NMR, the SQUID detection results in a better signal-to-noise ratio for a relatively high r-f field, (short pulses) while the conventional method becomes more advantageous with a decreasing r-f field.

New results of ultra-low temperature experiments in the second Landau level of a two-dimensional electron system.  

SciTech Connect

In the second Landau level around {nu} = 5/2 filling of an extremely high quality 2D electron system and at temperatures T down to 9 mK we observe a very strong even-denominator fractional quantum Hall effect at Landau level filling {nu} = 5/2 and its energy gap is large and {Delta} {approx} 0.45 K. A clear FQHE state is seen at {nu} = 2+2/5, with well-quantized R{sub xy}. A novel, even denominator FQHE state at {nu} = 2+3/8 seems to develop, as deduced from the T-dependence of dR{sub xy}/dB. In addition, four fully developed re-entrant integral quantum Hall effect (RIQHE) states are also observed. At low temperatures, the wide RIQHE plateau around at {nu} = 2+2/7 is interrupted by a dip, indicating an additional reentrance. Finally, the tilted magnetic field experiment at an ultra-low temperature of 10 mK was carried out to examine the spin-polarization of the {nu} = 5/2 FQHE state.

A Design Report of the Baseline for PEP-X: an Ultra-Low Emittance Storage Ring  

SciTech Connect

Over the past year, we have worked out a baseline design for PEP-X, as an ultra-low emittance storage ring that could reside in the existing 2.2-km PEPII tunnel. The design features a hybrid lattice with double bend achromat (DBA) cells in two arcs and theoretical minimum emittance (TME) cells in the remaining four arcs. Damping wigglers are used to reduce the horizontal emittance to 86 pm-rad at zero current for a 4.5 GeV electron beam. At a design current of 1.5 A, the horizontal emittance increases, due to intrabeam scattering, to 164 pm-rad when the vertical emittance is maintained at a diffraction limited 8 pm-rad. The baseline design will produce photon beams achieving a brightness of 10{sup 22} (ph/s/mm{sup 2}/mrad{sup 2}/0.1% BW) at 10 keV in a 3.5-m conventional planar undulator. Our study shows that an optimized lattice has adequate dynamic aperture, while accommodating a conventional off-axis injection system. In this report, we present the results of study, including the lattice properties, nonlinear dynamics, intra-beam scattering and Touschek lifetime, RF system, and collective instabilities.

Integrated production/use of ultra low-ash coal, premium liquids and clean char. Technical report, September 1, 1991--November 30, 1991  

SciTech Connect

This integrated, multi-product approach for utilizing Illinois coal starts with the production of ultra low-ash coal and then converts it to high-vale, coal-derived, products. The ultra low-ash coal is produced by solubilizing coal in a phenolic solvent under ChemCoal{trademark} process conditions, separating the coal solution from insoluble ash, and then precipitating the clean coal by dilution of the solvent with methanol. Two major products, liquids and low-ash char, are then produced by mild gasification of the low-ash coal. The low ash-char is further upgraded to activated char, and/or an oxidized activated char which has catalytic properties. Characterization of products at each stage is part of this project.

SciTech Connect

Conservation Research and Development/New Ultra-Low Carbon High Strength Steels with Improved Bake Hardenability for Enhanced Stretch Formability and Dent Resistance. The experimental work can be divided into four phases. In each phase, the materials were received or designed, processed and tested, to evaluate the BH increment or response, as a function of compositions and processing conditions. Microstructural characterization by various techniques was performed in order to gain insights into the mechanisms of flow stress increment by bake hardening.

Maglev Launch: Ultra?low Cost, Ultra?high Volume Access to Space for Cargo and Humans  

Science Journals Connector (OSTI)

Despite decades of efforts to reduce rocket launch costs improvements are marginal. Launch cost to LEO for cargo is ?$10 000 per kg of payload and to higher orbit and beyond much greater. Human access to the ISS costs $20 million for a single passenger. Unless launch costs are greatly reduced large scale commercial use and human exploration of the solar system will not occur. A new approach for ultra low cost access to space—Maglev Launch—magnetically accelerates levitated spacecraft to orbital speeds 8 km/sec or more in evacuated tunnels on the surface using Maglev technology like that operating in Japan for high speed passenger transport. The cost of electric energy to reach orbital speed is less than $1 per kilogram of payload. Two Maglev launch systems are described the Gen?1System for unmanned cargo craft to orbit and Gen?2 for large?scale access of human to space. Magnetically levitated and propelled Gen?1 cargo craft accelerate in a 100 kilometer long evacuated tunnel entering the atmosphere at the tunnel exit which is located in high altitude terrain (?5000 meters) through an electrically powered “MHD Window” that prevents outside air from flowing into the tunnel. The Gen?1 cargo craft then coasts upwards to space where a small rocket burn ?0.5 km/sec establishes the final orbit. The Gen?1 reference design launches a 40 ton 2 meter diameter spacecraft with 35 tons of payload. At 12 launches per day a single Gen?1 facility could launch 150 000 tons annually. Using present costs for tunneling superconductors cryogenic equipment materials etc. the projected construction cost for the Gen?1 facility is 20 billion dollars. Amortization cost plus Spacecraft and O&M costs total $43 per kg of payload. For polar orbit launches sites exist in Alaska Russia and China. For equatorial orbit launches sites exist in the Andes and Africa. With funding the Gen?1 system could operate by 2020 AD. The Gen?2 system requires more advanced technology. Passenger spacecraft enter the atmosphere at 70 000 feet where deceleration is acceptable. A levitated evacuated launch tube is used with the levitation force generated by magnetic interaction between superconducting cables on the levitated launch tube and superconducting cables on the ground beneath. The Gen?2 system could launch 100’s of thousands of passengers per year and operate by 2030 AD. Maglev launch will enable large human scale exploration of space thousands of gigawatts of space solar power satellites for beamed power to Earth a robust defense against asteroids and comets and many other applications not possible now.

Comparison of propane and methane performance and emissions in a turbocharged direct injection dual fuel engine  

SciTech Connect

With increasingly restrictive NO x and particulate matter emissions standards, the recent discovery of new natural gas reserves, and the possibility of producing propane efficiently from biomass sources, dual fueling strategies have become more attractive. This paper presents experimental results from dual fuel operation of a four-cylinder turbocharged direct injection (DI) diesel engine with propane or methane (a natural gas surrogate) as the primary fuel and diesel as the ignition source. Experiments were performed with the stock engine control unit at a constant speed of 1800 rpm, and a wide range of brake mean effective pressures (BMEPs) (2.7-11.6 bars) and percent energy substitutions (PESs) of C 3 H 8 and CH 4. Brake thermal efficiencies (BTEs) and emissions (NO x, smoke, total hydrocarbons (THCs), CO, and CO 2) were measured. Maximum PES levels of about 80-95% with CH 4 and 40-92% with C 3 H 8 were achieved. Maximum PES was limited by poor combustion efficiencies and engine misfire at low loads for both C 3 H 8 and CH 4, and the onset of knock above 9 bar BMEP for C 3 H 8. While dual fuel BTEs were lower than straight diesel BTEs at low loads, they approached diesel BTE values at high loads. For dual fuel operation, NO x and smoke reductions (from diesel values) were as high as 66-68% and 97%, respectively, but CO and THC emissions were significantly higher with increasing PES at all engine loads

ZnO film with ultra-low background electron concentration grown by plasma-assisted MBE using Mg film as the buffer layer  

SciTech Connect

Highlights: ? High quality ZnO film with ultra-low background electron concentration is grown by plasma-assisted molecular beam epitaxy using Mg film as a buffer layer. ? High resolution X-ray diffraction and photoluminescence (PL) spectroscopy indicate a high degree of crystallization. ? Hall measurement shows a carrier concentration as low as ?10{sup 14} cm{sup ?3}. ? The mechanism of the improved crystallinity is discussed in detail. -- Abstract: High quality ZnO epilayer with background electron concentration as low as 2.6 × 10{sup 14} cm{sup ?3} was obtained by plasma-assisted MBE on c-sapphire using a thin Mg film as the buffer layer. High-resolution XRD measurement shows a sharp (0 0 2) peak with full width at half maximum (FWHM) of only 0.029°. Photoluminescence spectroscopy presents a weak defect-related near-edge emission. A metal–semiconductor–metal (MSM) typed photodetector based on the material demonstrates a response of ?43 A/W under the bias of 1 V and an ON/OFF ratio of 10{sup 4}. This un-doped ZnO with ultra-low background electron concentration could be a promising starting material for p-type doping.

An ultra-low energy (30-200 eV) ion-atomic beam source for ion-beam-assisted deposition in ultrahigh vacuum  

SciTech Connect

The paper describes the design and construction of an ion-atomic beam source with an optimized generation of ions for ion-beam-assisted deposition under ultrahigh vacuum (UHV) conditions. The source combines an effusion cell and an electron impact ion source and produces ion beams with ultra-low energies in the range from 30 eV to 200 eV. Decreasing ion beam energy to hyperthermal values ({approx_equal}10{sup 1} eV) without loosing optimum ionization conditions has been mainly achieved by the incorporation of an ionization chamber with a grid transparent enough for electron and ion beams. In this way the energy and current density of nitrogen ion beams in the order of 10{sup 1} eV and 10{sup 1} nA/cm{sup 2}, respectively, have been achieved.

Hybrid adsorption-distillation process for separating propane and propylene  

SciTech Connect

The separation of propylene from a propane-propylene mixture by distillation is a energy-intensive process. A hybrid adsorption-distillation system has a great potential in reducing the energy consumption. A significant amount of energy can be saved relative to a process using only distillation, if a typical separation is carried out by distillation up to a propylene concentration of approximately 80% and then continuing the separation of propane from propylene by adsorption. A volumetric adsorption apparatus was designed to obtain the data at high pressures. The pure component data of propane and propylene were obtained on silica gel, molecular sieve 13X, and activated carbon. Although activated carbon has a greater capacity for both propane and propylene than either of the two adsorbents, it was only slightly selective for propylene. Silica gel has the greatest selectivity for propylene, which ranged from 2 to 4. None of the adsorbents was found to be selective for propane. The propane-propylene mixture behaved nonideally on the solid surface as indicated by the negative deviations of activity coefficients. The nonideality of the mixture can be attributed primarily to surface effects rather than to interactions between adsorbate molecules. A binary model has been proposed to predict mole fractions in the adsorbed phase and the total amount adsorbed from the pure component data. The pure component isotherm model of Hines et al. was extended to binary mixtures when the binary model was developed. Excellent agreement was obtained between experimental data and predicted values for mole fractions in the adsorbed phased, the total amount adsorbed, and adsorbed-phase activity coefficients.

Synthesis and Characterization of Gold Clusters Ligated with 1,3-Bis(dicyclohexylphosphino)propane  

SciTech Connect

In this multidisciplinary study we combine chemical reduction synthesis of novel gold clusters in solution with high-resolution analytical mass spectrometry (MS) to gain insight into the composition of the gold clusters and how their size, ionic charge state and ligand substitution influences their gas-phase fragmentation pathways. Ultra small cationic gold clusters ligated with 1,3-bis(dicyclohexylphosphino)propane (DCPP) were synthesized for the first time and introduced into the gas phase using electrospray ionization (ESI). Mass-selected cluster ions were fragmented employing collision induced dissociation (CID) and the product ions were analysed using MS. The solutions were found to contain the multiply charged cationic gold clusters Au9L43+, Au13L53+, Au6L32+, Au8L32+ and Au10L42+ (L = DCPP). The gas-phase fragmentation pathways of these cluster ions were examined systematically employing CID combined with MS. In addition, CID experiments were performed on related gold clusters of the same size and ionic charge state but capped with 1,3-bis(diphenylphosphino)propane (DPPP) ligands containing phenyl functional groups at the two phosphine centers instead of cyclohexane rings. It is shown that this relatively small change in the molecular substitution of the two phosphine centers in diphosphine ligands (C6H11 versus C6H5) exerts a pronounced influence on the size of the species that are preferentially formed in solution during reduction synthesis as well as the gas-phase fragmentation channels of otherwise identical gold cluster ions. The mass spectrometry results indicate that in addition to the length of the alkyl chain between the two phosphine centers, the substituents at the phosphine centers also play a crucial role in determining the composition, size and stability of diphosphine ligated gold clusters synthesized in solution.

Investigation of self-sealing in high-strength and ultra-low-permeability concrete in water using micro-focus X-ray CT  

SciTech Connect

High-strength and ultra-low-permeability concrete (HSULPC) is thought to be useful as a radioactive waste package. Thus, a high confining ability is desirable. For cementitious materials, sealing of cracks may occur in water due to the precipitation of calcium compounds. This can affect the confining ability. In this study, the sealing of a crack in HSULPC in water was investigated using micro-focus X-ray computed tomography (CT). The sealing by precipitation occurred only around the end of the specimen. Sealed regions of the crack were identified using three-dimensional image registration and CT image subtraction of images obtained for the specimen before and after it was immersed in water to evaluate temporal changes of the sealing deposits in the crack. The sealing deposits increased as the HSULPC specimen was kept in water longer. It was concluded that cracks in HSULPC in water are sealed by precipitation.

Combustion behaviour of a heavy duty common rail marine Diesel engine fumigated with propane  

Science Journals Connector (OSTI)

This paper presents results from the testing of a heavy duty common rail marine Diesel engine with electronically controlled two stage liquid fuel injection, operating under load on a test bench with propane mixed into the inlet air at various rates. Results are presented for a range of engine loads, with brake mean effective pressure up to 22 bar at 1800 rpm. The electronic engine control unit is not modified and allowed to respond to the addition of propane according to its inbuilt map. This results in retarded injection timing with increased propane addition at some test points. At each test point, constant engine speed and brake torque are maintained for various rates of propane addition. Cylinder pressure and the injector activation voltage are recorded with a high speed data acquisition system. Apparent heat release rate is calculated from the measured cylinder pressure. At high rates of propane addition very high pressure rise rates and severe knock are measured. At the high brake mean effective pressure conditions tested, knock limits propane supply rates to less than 20% by energy. Small increases in thermal efficiency are indicated with moderate rates of propane addition. Exhaust emissions of NOx, CO, HC and smoke are measured. CO, HC and smoke emissions increase significantly with increasing propane addition. For high propane supply rates, two distinct peaks in heat release rate are measured. Analysis is made of the flammability of the propane–air mixtures at the elevated temperatures at the end of the compression stroke, using the modified Burgess–Wheeler Law. At propane supply rates greater than 25%, the propane–air mixture is flammable in its own right at compression temperature. The apparent heat release rate, fuel injection timing and flammability data allow analysis of the mechanism of the combustion process with propane fumigation.

Strange Particle Production by Bevatron Neutrons in Propane  

Science Journals Connector (OSTI)

A liquid propane bubble chamber was exposed to a beam of neutrons with energies up to 6 Bev from the Bevatron. 10 000 pictures of interactions in the hydrocarbon were scanned to detect neutral heavy unstable particles. 349 neutral V-events were found, most of which came from the stainless steel walls of the chamber. 86% of these events could be identified as one or the other or either of the neutral strange particles: ?0 or ?10. The ?0?10 ratio is about 0.6.8200 stars of 2 or more prongs formed by neutrons interacting in the liquid propane were observed in the chamber and 17 of these produced V0's. An additional 5 V0's were formed in single-prong events produced by neutrons, and 8 others were produced in events in the propane caused by charged particles.The energy spectrum of the incident neutrons was estimated from study of ?-meson production interactions in the hydrogen. The distribution shows that the neutrons had energies up to 6 Bev with a mean value of about 4 Bev. For the energy range 1 to 6 Bev, the production of strange particles occurs in about 1% of all inelastic interactions of neutrons with hydrogen and carbon.

The realisation of an on-board emission measuring system serving as a R&D tool for ultra low emitting vehicles  

Science Journals Connector (OSTI)

The negative impact of deteriorating air quality on public health etc. is receiving growing attention. As a result, the contributing emission sources are increasingly regulated. Thus, the emissions of road transport - being one of the largest contributors - are under constant pressure. As such, the evolving legislation on emissions of new cars is forcing to ultra low emitting vehicles. To assist in the development of those vehicles an on-board measuring system capable of determining ppm level emissions of carbon monoxide (CO), total hydrocarbons (THC) and nitrogen oxides (NOx) is realised. This system combines the latest in laboratory grade analysers with a high speed condensing type sampling system in a state of the-art shock proof design. The regulated emission components can be detected to at least one ppm. The data-acquisition allows for the simultaneous retrieval of engine and vehicle parameters in order to calculate on-line mass based time resolved emissions that can be quickly linked to relevant parameters of the emission control system. The data treatment is automated under LabView. The on-board system is validated by over 130 comparative simultaneous measurements on a Constant Volume Sampling chassis dynamometer. The tests are executed on three modern light duty vehicles of which one ultra low emitting Euro 4 certified petrol one. The comparison revealed that differences in emissions are below 10% except for very low levels i.e. underneath 0.02 g/km where the reference system is thought to be more inaccurate then the on-board one. On-board emission measurements performed on a Euro 4 petrol vehicle showed differences of more then a decade when compared to the type approval cycle on chassis dynamometer. An in-depth analysis revealed that, outside this cycle, the engine can be differently calibrated resulting in deviations from the stoichiometric air to fuel ratio and subsequent raise in emissions. Also, very short emission events could be studied such as NOx raise during accelerations immediately following a motoring period. This could be attributed to a slightly lean air fuel mixture just at the start of fuel injection.

Experimental study on transmission of an overdriven detonation wave from propane/oxygen to propane/air  

SciTech Connect

Two sets of experiments were performed to achieve a strong overdriven state in a weaker mixture by propagating an overdriven detonation wave via a deflagration-to-detonation transition (DDT) process. First, preliminary experiments with a propane/oxygen mixture were used to evaluate the attenuation of the overdriven detonation wave in the DDT process. Next, experiments were performed wherein a propane/oxygen mixture was separated from a propane/air mixture by a thin diaphragm to observe the transmission of an overdriven detonation wave. Based on the characteristic relations, a simple wave intersection model was used to calculate the state of the transmitted detonation wave. The results showed that a rarefaction effect must be included to ensure that there is no overestimate of the post-transmission wave properties when the incident detonation wave is overdriven. The strength of the incident overdriven detonation wave plays an important role in the wave transmission process. The experimental results showed that a transmitted overdriven detonation wave occurs instantaneously with a strong incident overdriven detonation wave. The near-CJ state of the incident wave leads to a transmitted shock wave, and then the transition to the overdriven detonation wave occurs downstream. The attenuation process for the overdriven detonation wave decaying to a near-CJ state occurs in all tests. After the attenuation process, an unstable detonation wave was observed in most tests. This may be attributed to the increase in the cell width in the attenuation process that exceeds the detonability cell width limit. (author)

Unusual behavior of propane as a co-guest during hydrate formation in silica sand: Potential application to seawater desalination and carbon dioxide capture  

Science Journals Connector (OSTI)

Abstract We report an unusual behavior of hydrate formation in silica sand with gas mixtures containing propane as a co-guest. Based on morphology study we observed that propane as a co-guest has the ability to draw water dispersed in silica sand to the hydrate formation region and showed a tendency to result in drastic hydrate growth due to the migration of water molecules to the gas phase region. Hydrate nucleation occurred in the interstitial pore space between the silica sand particles and hydrate growth occurred in the gas phase above the silica sand bed and to sustain the hydrate growth, dispersed water was drawn towards the hydrate growth front. In addition, we elucidated the effect of sand bed height to maximize the growth rates utilizing this behavior that results in enhanced kinetics. We propose conceptual designs for utilizing this behavior of propane as a co-guest in sand for seawater desalination and an innovative approach to simultaneously capture carbon dioxide and desalinate seawater.

A novel adsorption-distillation hybrid scheme is proposed for propane/propylene separation. The suggested scheme has potential for saving up to [approximately]50% energy and [approximately]15-30% in capital costs as compared with current technology. The key concept of the proposed scheme is to separate olefins from alkanes by adsorption and then separate individual olefins and alkanes by simple distillation, thereby eliminating energy intensive and expensive olefin-alkane distillation. A conceptual flow schematic for the proposed hybrid scheme and potential savings are outlined.s

In this study, basic data for the HSULPC regarding its the impervious character and the thermodynamics during cement hydration were obtained through water permeability measurements using cold isostatic pressing (CIP) and adiabatic concrete hydration experiments, respectively. Then, a prediction tool to find concrete package construction conditions to avoid thermal cracking was developed, which could deal with coupled calculations of cement hydration, heat transfer, stress, and cracking. The developed tool was applied to HSULPC hydration on a small-scale cylindrical model to examine whether there was any effect on cracking which depended on the ratio of concrete cylinder thickness to its inner diameter. The results were compared to experiments. For concrete with a compressive strength of 200MPa, the water permeability coefficient was 4 x 10{sup 19} m/s. Dependences of activation energy and frequency factor on degree of cement hydration had a sharp peaking due to the nucleation rate-determining step, and a gradual increase region due to the diffusion rate-determining step. From analyses of the small-scale cylindrical model, dependences of the maximum principal stress on the radius were obtained. When the ratio of the concrete thickness to the heater diameter was around 1, the risk of cracking was predicted to be minimized. These numerical predictions from the developed tool were verified by experiments.

Performance and Emissions Characteristics of Bio-Diesel (B100)-Ignited Methane and Propane Combustion in a Four Cylinder Turbocharged Compression Ignition Engine  

SciTech Connect

Different combustion strategies and fuel sources are needed to deal with increasing fuel efficiency demands and emission restrictions. One possible strategy is dual fueling using readily available resources. Propane and natural gas are readily available with the current infrastructure and biodiesel is growing in popularity as a renewable fuel. This paper presents experimental results from dual fuel combustion of methane (as a surrogate for natural gas) and propane as primary fuels with biodiesel pilots in a 1.9 liter, turbocharged, 4 cylinder diesel engine at 1800 rev/min. Experiments were performed with different percentage energy substitutions (PES) of propane and methane and at different brake mean effective pressures (BMEP/bmep). Brake thermal efficiency (BTE) and emissions (NOx, HC, CO, CO2, O2 and smoke) were also measured. Maximum PES levels for B100-methane dual fuelling were limited to 70% at 2.5 bar bmep and 48% at 10 bar bmep, and corresponding values for B100-propane dual fuelling were 64% and 43%, respectively. Maximum PES was limited by misfire at 2.5 bar bmep and the onset of engine knock at 10 bar bmep. Dual fuel BTEs approached straight B100 values at 10 bar bmep while they were significantly lower than B100 values at 2.5 bar bmep. In general dual fuelling was beneficial in reducing NOx and smoke emissions by 33% and 50%, respectively from baseline B100 levels; however, both CO and THC emissions were significantly higher than baseline B100 levels at all PES and loads.

Propane ammoxidation over Mo–V–Te–Nb–O M1 phase: Density functional theory study of propane oxidative dehydrogenation steps  

Science Journals Connector (OSTI)

Abstract Propane ammoxidation to acrylonitrile catalyzed by the bulk Mo–V–Te–Nb oxides has received considerable attention because it is more environmentally benign than the current process of propylene ammoxidation and relies on a more abundant feedstock. This process is proposed to consist of a series of elementary steps including propane oxidative dehydrogenation (ODH), ammonia and O2 activation, \\{NHx\\} insertion into C3 surface intermediates, etc. Density functional theory calculations were performed here to investigate the three sequential H abstraction steps that successively convert propane into isopropyl, propene, and ?-allyl on cation sites in the proposed selective and active center present in the ab plane of the Mo–V–Te–Nb–O M1 phase. The initial H abstraction from propane was found to be the rate-limiting step of this process, consistent with both the proposed reaction mechanism for propane ammoxidation on the Mo–V–Te–Nb oxides and current understanding of V5+ as the active site for alkane activation on V-based oxides. Te=O was found to be significantly more active than V5+=O for the H abstraction from propane, which suggests that the surface and bulk Te species may be different. The role of Mo=O is most likely limited to being an H acceptor from isopropyl to form propene under ammoxidation conditions.

Polarization effects on low-energy electron collisions with propane  

Science Journals Connector (OSTI)

We employed the Schwinger multichannel method to compute elastic cross sections for low-energy electron collisions with propane (C3H8). The calculations are carried out within the static-exchange and static-exchange plus polarization approximations and covered the energy range from 0 to 15 eV. The computed differential cross sections show good agreement with the experiment, and the computed integral cross sections present the same shape as the measured total cross sections. We found a broad structure in the integral cross section around 8.5 eV and also a Ramsauer-Townsend minimum around 0.1 eV. These results are in agreement with the experimental observations.

Simulation of hydrogen and hydrogen-assisted propane ignition in Pt catalyzed microchannel  

SciTech Connect

This paper deals with self-ignition of catalytic microburners from ambient cold-start conditions. First, reaction kinetics for hydrogen combustion is validated with experimental results from the literature, followed by validation of a simplified pseudo-2D microburner model. The model is then used to study the self-ignition behavior of lean hydrogen/air mixtures in a Platinum-catalyzed microburner. Hydrogen combustion on Pt is a very fast reaction. During cold start ignition, hydrogen conversion reaches 100% within the first few seconds and the reactor dynamics are governed by the ''thermal inertia'' of the microburner wall structure. The self-ignition property of hydrogen can be used to provide the energy required for propane ignition. Two different modes of hydrogen-assisted propane ignition are considered: co-feed mode, where the microburner inlet consists of premixed hydrogen/propane/air mixtures; and sequential feed mode, where the inlet feed is switched from hydrogen/air to propane/air mixtures after the microburner reaches propane ignition temperature. We show that hydrogen-assisted ignition is equivalent to selectively preheating the inlet section of the microburner. The time to reach steady state is lower at higher equivalence ratio, lower wall thermal conductivity, and higher inlet velocity for both the ignition modes. The ignition times and propane emissions are compared. Although the sequential feed mode requires slightly higher amount of hydrogen, the propane emissions are at least an order of magnitude lower than the other ignition modes. (author)

Effect of temperature and pressure on the dynamics of nanoconfined propane  

SciTech Connect

We report the effect of temperature and pressure on the dynamical properties of propane confined in nanoporous silica aerogel studied using quasielastic neutron scattering (QENS). Our results demonstrate that the effect of a change in the pressure dominates over the effect of temperature variation on the dynamics of propane nano-confined in silica aerogel. At low pressures, most of the propane molecules are strongly bound to the pore walls, only a small fraction is mobile. As the pressure is increased, the fraction of mobile molecules increases. A change in the mechanism of motion, from continuous diffusion at low pressures to jump diffusion at higher pressures has also been observed.

A rapid compression machine study of the oxidation of propane in the negative temperature coefficient regime  

SciTech Connect

The oxidation of propane has been studied in the temperature range 680-970 K at compressed gas pressures of 21, 27, and 37 atm and at varying equivalence ratios of 0.5, 1.0, and 2.0. These data are consistent with other experiments presented in the literature for alkane fuels in that, when ignition delay times are plotted as a function of temperature, a characteristic negative coefficient behavior is observed. In addition, these data were simulated using a detailed chemical kinetic model. It was found that qualitatively the model correctly simulated the effect of change in equivalence ratio and pressure, predicting that fuel-rich, high-pressure mixtures ignite fastest, while fuel-lean, low-pressure mixtures ignite slowest. Moreover, reactivity as a function of temperature is well captured, with the model predicting negative temperature coefficient behavior similar to the experiments. Quantitatively the model is faster than experiment for all mixtures at the lowest temperatures (650-750 K) and is also faster than experiment throughout the entire temperature range for fuel-lean mixtures.

We precisely measured conductance spectra near the zero-bias conductance peak (ZBCP) in La0.67Sr0.33MnO3/YBa2Cu3O7?? junctions, which reflects the formation of the surface bound states in the d-wave superconductors. When the conductance spectra of the junctions were measured at ultra-low temperatures (mK), very sharp \\{ZBCPs\\} were observed. We found the notable features of the magnetic field response of the ZBCP, i.e., the coexistence of spin-dependent and spin-independent components in the ZBCP and the apparent absence of the Zeeman splitting.

A novel integrated thermally double coupled configuration for methane steam reforming, methane oxidation and dehydrogenation of propane  

Science Journals Connector (OSTI)

Abstract The goal of this study is the simultaneous production of synthesis gas, hydrogen and propylene in a thermally double coupled steam reformer reactor. This reactor has three concentric tubes where the exothermic reaction of methane oxidation is supposed to occur in the middle tube and the inner and outer tubes are considered to be endothermic sides of steam reforming and propane dehydrogenation, respectively. The motivation is to combine the energy efficient concept of coupling one exothermic reaction with two endothermic reactions, enhancement of synthesis gas production, propylene and hydrogen production and also producing two different H2/CO ratio streams of syngas. A steady state homogeneous model of fixed bed for three sides predicts the performance of this new configuration. The simulation results are compared with corresponding predictions of the conventional steam reformer. The results prove that synthesis gas production is increased in a thermally double coupled reactor in comparison with conventional steam reforming. In addition, the thermally double coupled reactor reduces the capital and operating costs by reducing the reactor size and consumption of energy.

No. 2 heating oil/propane program 1994--1995. Final report  

SciTech Connect

During the 1994--95 heating season, the Massachusetts Division of Energy Resources (DOER) participated in a joint data collection program between several state energy offices and the federal Department of Energy`s (DOE) Energy Information Administration (EIA). The purpose of the program was to collect and monitor retail and wholesale heating oil and propane prices and inventories from October 1994 through March 1995. This program augmented the existing Massachusetts data collection system and served several important functions. The information helped the federal and state governments respond to consumer, congressional and media inquiries regarding No. 2 oil and propane. The information also provided policy decision-makers with timely, accurate and consistent data to monitor current heating oil and propane markets and develop appropriate state responses when necessary. In addition, the communication network between states and the DOE was strengthened through this program. This final report begins with an overview of the unique events that had an impact on the petroleum markets prior to and during the reporting period. Next, the report summarizes the results from residential heating oil and propane price surveys conducted by DOER over the 1994--95 heating season. The report also incorporates the wholesale heating oil and propane prices and inventories collected by EIA and distributed to the states. Finally, the report outlines DOER`s use of the data.

Dynamics of Propane in Silica Mesopores Formed upon PropyleneHydrogenation over Pt Nanoparticles by Time-Resolved FT-IRSpectroscopy  

SciTech Connect

Propylene hydrogenation over Pt nanoparticles supported onmesoporous silica type SBA-15 was monitored by time-resolved FT-IRspectroscopy at 23 ms resolution using short propylene gas pulses thatjoined a continuous flow of hydrogen in N2 (1 atm total pressure).Experiments were conducted in the temperature range 323-413 K. Propanewas formed within 100 milliseconds or faster. The CH stretching regionrevealed distinct bands for propane molecules emerging inside thenanoscale channels of the silica support. Spectral analysis gave thedistribution of the propane product between support and surrounding gasphase as function of time. Kinetic analysis showed that the escape ofpropane molecules from the channels occurred within hundreds ofmilliseconds (3.1 + 0.4 s-1 at 383 K). A steady state distribution ofpropane between gas phase and mesoporous support is established as theproduct is swept from the catalyst zone by the continuous flow ofhydrogen co-reactant. This is the first direct spectroscopic observationof emerging products of heterogeneous catalysis on nanoporous supportsunder reaction conditions.

Aromatization of propane: Techno-economic analysis by multiscale “kinetics-to-process” simulation  

Science Journals Connector (OSTI)

Abstract This paper addresses the techno-economic analysis of the propane aromatization process, by adopting a novel kinetics-to-process approach. The recent interest in this technological route derives from the development of new third generation biorefinery concepts, in which, algal oil is subjected to catalytic hydrodeoxygenation processes for the production of (Hydrotreated Renewable Jet) HRJ fuels. Beside biofuels, co-production of large amounts of propane is observed, which can be upgraded by a catalytic conversion to aromatics on zeolites. Kinetic studies of propane aromatization over H-ZSM-5 zeolite in a wide range of conversions are reported in the literature. Based on these results, a general kinetic model of propane aromatization has been developed. The revised kinetic scheme is then embedded in a process simulation, performed with the commercial code SimSci PRO/II by Schneider Electric. Basing on the process simulation and on available price assessments, a techno-economic analysis has been performed to show limits as well as potentialities of the proposed layout.

Metallurgical failure analysis of a propane tank boiling liquid expanding vapor explosion (BLEVE).  

SciTech Connect

A severe fire and explosion occurred at a propane storage yard in Truth or Consequences, N.M., when a truck ran into the pumping and plumbing system beneath a large propane tank. The storage tank emptied when the liquid-phase excess flow valve tore out of the tank. The ensuing fire engulfed several propane delivery trucks, causing one of them to explode. A series of elevated-temperature stress-rupture tears developed along the top of a 9800 L (2600 gal) truck-mounted tank as it was heated by the fire. Unstable fracture then occurred suddenly along the length of the tank and around both end caps, along the girth welds connecting the end caps to the center portion of the tank. The remaining contents of the tank were suddenly released, aerosolized, and combusted, creating a powerful boiling liquid expanding vapor explosion (BLEVE). Based on metallography of the tank pieces, the approximate tank temperature at the onset of the BLEVE was determined. Metallurgical analysis of the ruptured tank also permitted several hypotheses regarding BLEVE mechanisms to be evaluated. Suggestions are made for additional work that could provide improved predictive capabilities regarding BLEVEs and for methods to decrease the susceptibility of propane tanks to BLEVEs.

Novel Pt/Mg(In)(Al)O catalysts for ethane and propane dehydrogenation  

SciTech Connect

Catalysts for the dehydrogenation of light alkanes were prepared by dispersing Pt on the surface of a calcined hydrotalcite-like support containing indium, Mg(In)(Al)O. Upon reduction in H{sub 2} at temperatures above 673 K, bimetallic particles of PtIn are observed by TEM, which have an average diameter of 1 nm. Analysis of Pt LIII-edge extended X-ray absorption fine structure (EXAFS) data shows that the In content of the bimetallic particles increases with increasing bulk In/Pt ratio and reduction temperature. Pt LIII-edge X-ray absorption near edge structure (XANES) indicates that an increasing donation of electronic charge from In to Pt occurs with increasing In content in the PtIn particles. The activity and selectivity of the Pt/Mg(In)(Al)O catalysts for ethane and propane dehydrogenation reactions are strongly dependent on the bulk In/Pt ratio. For both reactants, maximum activity was achieved for a bulk In/Pt ratio of 0.48, and at this In/Pt ratio, the selectivity to alkene was nearly 100%. Coke deposition was observed after catalyst use for either ethane or propane dehydrogenation, and it was observed that the alloying of Pt with In greatly reduced the amount of coke deposited. Characterization of the deposit by Raman spectroscopy indicates that the coke is present as highly disordered graphite particles <30 nm in diameter. While the amount of coke deposited during ethane and propane dehydrogenation are comparable, the effects on activity are dependent on reactant composition. Coke deposition had no effect on ethane dehydrogenation activity, but caused a loss in propane dehydrogenation activity. This difference is attributed to the greater ease with which coke produced on the surface of PtIn nanoparticles migrates to the support during ethane dehydrogenation versus propane dehydrogenation.

Effects of alloying elements on the strength and cooling rate sensitivity of ultra-low carbon alloy steel weld metals. Technical report  

SciTech Connect

A study was conducted to evaluate the effect of weld cooling rate on the strength of autogenous GTAW deposited weld metal. The basic weld metal composition was based on a low carbon bainite metallurgical system. The weld metal yield strength goal was 130 ksi, needed to surpass the current HY-13O weld metal requirements. Vacuum Induction Melted (VIM) heats of steel were produced and processed into 3/4` thickness plates. The autogenous gas tungsten arc welds (GTAW) on the parent steel plates were produced under two different heat input conditions. Tensile specimens were produced from the weldments; specimens from certain heats were subjected to gleeble thermal simulations of multi-pass welding conditions using the Gleeble 1500. All specimens were then evaluated for yield and ultimate tensile strength. From the data presented, it was found that the experimental compositions studied were less sensitive to cooling rate than current HY-130 welding consumables. The compositions tested approached the target yield strength of 130 ksi, but further work is necessary in this area.

Towards a kinetic understanding of the ignition of air-propane mixture by a non-equilibrium discharge: the decomposition mechanisms of propane  

Science Journals Connector (OSTI)

The decomposition of propane in non-thermal plasmas of N2/C3H8 and N2/O2/C3H8 mixtures (oxygen percentage up to 20%) at low temperature is studied in a photo-triggered discharge. Quenching of nitrogen metastable states dissociate C3H8 to produce propene and hydrogen. Oxidation reactions are growing in importance when the O2 concentration increases, but the dissociation quenching reactions still occurs for the air-based mixture. Even for a low concentration of oxygen, OH is an important specie involved in the conversion of the hydrocarbon. A kinetic analysis emphasises that OH comes in great part from the production of H, in which the methyl radical plays a role, strengthening the role of the dissociation processes of propane and propene in the medium reactivity. Results of PLIF measurements performed on OH during the diffuse afterglow of a nanosecond corona discharge correlate with results obtained on the photo-triggered discharge.

Propane dehydrogenation over Al2O3 supported Pt nanoparticles: Effect of cerium addition  

Science Journals Connector (OSTI)

Abstract The catalyst of Pt nanoparticles loaded on Al2O3 support has been prepared by a facile liquid phase synthesis–ultrasonic vibration method. With propane dehydrogenation as a probe reaction, the influence of promoter cerium (Ce) on the catalyst was investigated by means of transmission electron microscope (TEM), X-ray diffraction (XRD), N2 adsorption–desorption, X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy of CO adsorption, H2-temperature programmed reduction (H2-TPR), and catalytic properties for propane dehydrogenation. The results revealed that the Pt nanograins with diameter of 1.6–4.8 nm were evenly dispersed on the Ce-containing Al2O3 support. The introduction of a small amount Ce into Pt/Al2O3 results in a bimetallic surface interaction, enhancing the surface reducibility and dispersity of Pt nanoparticles. The study of propane dehydrogenation performance shows that Ce-containing Pt catalyst is more active and less coke deposition than Ce-free Pt/Al2O3 counterpart. This study can provide an insight into the design and development of new Pt-based catalyst, especially for the improvement of catalytic activity and stability towards alkane dehydrogenation.

A prospective randomized multicenter clinical trial of the Provox2 and Groningen Ultra Low Resistance voice prostheses in the rehabilitation of post-laryngectomy patients: A lifetime and preference study  

Science Journals Connector (OSTI)

Summary To prospectively study patients’ preference for and the lifetime of the Groningen Ultra Low Resistance (GULR) and Provox2 tracheo-esophageal shunt prosthesis (TESP, plural TESPs) in post-laryngectomy patients. Eighty post-laryngectomy patients were included in 4 oncological centers in the Netherlands. We used a repeated measures design study with 4 randomized groups in a partial cross-over design using 3 consecutive \\{TESPs\\} (3 intervals) in different orders. (Group 1: GULR-GULR-GULR; Group 2: GULR-GULR-Provox2; Group 3: Provox2-Provox2-GULR; and Group 4: Provox2- Provox2-Provox2). Replacement dates and reasons for replacement were monitored with questionnaires as were patients’ preferences for GULR or Provox2. A great variability of lifetime within and between groups was seen. Mean lifetimes found (all groups and intervals added) were 106.2 and 102.7 days, and median lifetimes were 76 and 65 days for GULR and Provox2, respectively. Lifetime showed no significant differences between groups, intervals, and TESP types. Many patients dropped out due to reasons having to do with GULR-characteristics (n = 21). The main dropout reason was “high phonating resistance (HPR)” (57.1%). Only 10 patients preferred GULR. A significantly larger number of patients (n = 39, 79.6%) preferred Provox2 either by choice or by dropping out due to GULR-characteristics (P < 0.001). The main replacement reasons were “leakage though TESP” (GULR 59.1%, Provox2 52.1%) and HPR (GULR 15.9%, Provox2 12.7%). No significant differences in lifetime between GULR and Provox2 were found. The patients’ preference for Provox2 was significant (P < 0.001). Patients’ preference was a more important outcome measurement in TESP effectiveness than device lifetime.

Search for 2{nu}{beta}{beta} Decay of {sup 130}Te to the First Excited State of {sup 130}Xe with an Ultra-Low-Background Germanium Crystal Array  

SciTech Connect

The goal of searching for zero-neutrino double-beta (0{nu}{beta}{beta}) decay is to probe an absolute neutrino mass scale suggested by the mass-splitting parameters observed by neutrino oscillation experiments. Furthermore, observation of 0{nu}{beta}{beta} decay is an explicit instance of Lepton-number non-conservation. A sensitive measurement of two-neutrino double-beta (2{nu}{beta}{beta}) decay can provide critical input to Quasiparticle Random Phase Approximation (QRPA) calculations of the nuclear matrix elements in models similar to those used to extract the absolute neutrino mass from (0{nu}{beta}{beta}) decay experiments. Tellurium-130, an even-even nucleus, can undergo 2{nu}{beta}{beta} decay to the first 0+ excited state of {sup 130}Xe producing three possible {gamma}-ray cascades as it transitions to the ground state. The Cascades detector is a high purity germanium (HPGe) crystal array consisting of two ultra-low-background copper cryostats each housing a hexagonal array of seven crystals. The project is currently being developed at Pacific Northwest National Laboratory in Richland, WA (USA), and aims to obtain very high {gamma}-ray detection efficiency while utilizing highly effective and low-background shielding. GEANT4 simulations of the detector are performed for a {sup 130}Te sample in order to determine the optimum size and geometry of the source for maximum detection efficiency and predict its sensitivity for measuring 2{nu}{beta}{beta} decay to the first 0+ excited state of {sup 130}Xe. These simulations are validated with calibration sources and presented.

An investigation of diesel–ignited propane dual fuel combustion in a heavy-duty diesel engine  

Science Journals Connector (OSTI)

Abstract This paper presents a detailed experimental analysis of diesel–ignited propane dual fuel combustion on a 12.9-l, six-cylinder, production heavy-duty diesel engine. Gaseous propane was fumigated upstream of the turbocharger air inlet and ignited using direct injection of diesel sprays. Results are presented for brake mean effective pressures (BMEP) from 5 to 20 bar and different percent energy substituted (PES) by propane at a constant engine speed of 1500 rpm. The effect of propane PES on apparent heat release rates, combustion phasing and duration, fuel conversion and combustion efficiencies, and engine-out emissions of oxides of nitrogen (NOx), smoke, carbon monoxide (CO), and total unburned hydrocarbons (HC) were investigated. Exhaust particle number concentrations and size distributions were also quantified for diesel–ignited propane combustion. With stock engine parameters, the maximum propane PES was limited to 86%, 60%, 33%, and 25% at 5, 10, 15, and 20 bar BMEPs, respectively, either by high maximum pressure rise rates (MPRR) or by excessive HC and CO emissions. With increasing PES, while fuel conversion efficiencies increased slightly at high \\{BMEPs\\} or decreased at low BMEPs, combustion efficiencies uniformly decreased. Also, with increasing PES, \\{NOx\\} and smoke emissions were generally decreased but these reductions were accompanied by higher HC and CO emissions. Exhaust particle number concentrations decreased with increasing PES at low loads but showed the opposite trends at higher loads. At 10 bar BMEP, by adopting a different fueling strategy, the maximum possible propane PES was extended to 80%. Finally, a limited diesel injection timing study was performed to identify the optimal operating conditions for the best efficiency-emissions-MPRR tradeoffs.

Fraction of Stopped Antiprotons which Annihilate on Free Hydrogen in Propane  

Science Journals Connector (OSTI)

Antiprotons were stopped in a liquid-propane bubble chamber. In a sample of film containing 75 000 annihilations at rest, 21 examples of the reactions p¯p??+?- or p¯p?K+K- were identified. This number, together with the previously measured branching ratios of these channels in liquid hydrogen, leads to a determination that (11±3)% of the antiprotons annihilate on free protons. The remaining 89% annihilate on bound nucleons in carbon. This fraction is markedly higher than the fraction of ?- at rest which charge exchange on free protons in similar hydrocarbons. An explanation of the large difference is suggested.

Analysis of ignition behavior in a turbocharged direct injection dual fuel engine using propane and methane as primary fuels  

SciTech Connect

This paper presents experimental analyses of the ignition delay (ID) behavior for diesel-ignited propane and diesel-ignited methane dual fuel combustion. Two sets of experiments were performed at a constant speed (1800 rev/min) using a 4-cylinder direct injection diesel engine with the stock ECU and a wastegated turbocharger. First, the effects of fuel-air equivalence ratios (���© pilot �¢���¼ 0.2-0.6 and ���© overall �¢���¼ 0.2-0.9) on IDs were quantified. Second, the effects of gaseous fuel percent energy substitution (PES) and brake mean effective pressure (BMEP) (from 2.5 to 10 bar) on IDs were investigated. With constant ���© pilot (> 0.5), increasing ���© overall with propane initially decreased ID but eventually led to premature propane autoignition; however, the corresponding effects with methane were relatively minor. Cyclic variations in the start of combustion (SOC) increased with increasing ���© overall (at constant ���© pilot), more significantly for propane than for methane. With increasing PES at constant BMEP, the ID showed a nonlinear (initially increasing and later decreasing) trend at low BMEPs for propane but a linearly decreasing trend at high BMEPs. For methane, increasing PES only increased IDs at all BMEPs. At low BMEPs, increasing PES led to significantly higher cyclic SOC variations and SOC advancement for both propane and methane. Finally, the engine ignition delay (EID) was also shown to be a useful metric to understand the influence of ID on dual fuel combustion.

Influence of propane on CO2/CH4 and N2/CH4 separations in CHA zeolite membranes  

Science Journals Connector (OSTI)

Abstract Two types of CHA zeolite membranes (SAPO-34, SSZ-13) were used for CO2/CH4, N2/CH4, and CO2/i-butane separations at both low (270 and 350 kPa) and high (1.73 MPa) pressures. The SSZ-13 membranes were more selective, with CO2/CH4 separation selectivities as high as 280 and N2/CH4 separation selectivities of 12 at 270 kPa feed pressure. For both types of membranes, selectivities and permeances decreased as the feed pressure increased. The CO2/i-butane separation selectivities were greater than 500,000 for SAPO-34 membranes, indicating extremely low densities of defects because i-butane is too large to enter the CHA pores. The CO2/i-butane selectivities were smaller for SSZ-13 membranes (2,800–20,000), in part because the SSZ-13 layer was on the outside of the porous mullite tubes and sealing the membrane on the zeolite surface was more difficult than for the SAPO-34 membranes that were grown on the inside of glazed alumina tubes. Propane, in feed concentrations from 1 to 9%, significantly influenced separations by decreasing permeances in most cases. The effect was larger for N2/CH4 than for CO2/CH4 mixtures, apparently because the more strongly-adsorbing CO2 competes better than N2 with propane for adsorption sites. Although propane caused permeances to decrease significantly over time, selectivities decreased much less. Propane decreased permeances more for SAPO-34 membranes than for SSZ-13 membranes at 350 kPa, and at high pressure propane even increased CO2 permeances and decreased CH4 permeances in SSZ-13 membranes, thus significantly increasing CO2/CH4 selectivities. Propane permeances reached steady state relatively quickly because its permeation was mostly through defects, but CO2, N2, and CH4 permeances did not stabilize in the presence of propane, even after seven days. The effects of propane were reversible when it was removed from the feed and the membranes were heated.

Shock tube and theoretical studies on the thermal decomposition of propane : evidence for a roaming radical channel.  

SciTech Connect

The thermal decomposition of propane has been studied using both shock tube experiments and ab initio transition state theory-based master equation calculations. Dissociation rate constants for propane have been measured at high temperatures behind reflected shock waves using high-sensitivity H-ARAS detection and CH{sub 3} optical absorption. The two major dissociation channels at high temperature are C{sub 3}H{sub 8} {yields} CH{sub 3} + C{sub 2}H{sub 5} (eq 1a) and C{sub 3}H{sub 8} {yields} CH{sub 4} + C{sub 2}H{sub 4} (eq 1b). Ultra high-sensitivity ARAS detection of H-atoms produced from the decomposition of the product, C{sub 2}H{sub 5}, in (1a), allowed measurements of both the total decomposition rate constants, k{sub total}, and the branching to radical products, k{sub 1a}/k{sub total}. Theoretical analyses indicate that the molecular products are formed exclusively through the roaming radical mechanism and that radical products are formed exclusively through channel 1a. The experiments were performed over the temperature range 1417-1819 K and gave a minor contribution of (10 {+-} 8%) due to roaming. A multipass CH{sub 3} absorption diagnostic using a Zn resonance lamp was also developed and characterized in this work using the thermal decomposition of CH{sub 3}I as a reference reaction. The measured rate constants for CH{sub 3}I decomposition agreed with earlier determinations from this laboratory that were based on I-atom ARAS measurements. This CH{sub 3} diagnostic was then used to detect radicals from channel 1a allowing lower temperature (1202-1543 K) measurements of k1a to be determined. Variable reaction coordinate-transition state theory was used to predict the high pressure limits for channel (1a) and other bond fission reactions in C{sub 3}H{sub 8}. Conventional transition state theory calculations were also used to estimate rate constants for other tight transition state processes. These calculations predict a negligible contribution (<1%) from all other bond fission and tight transition state processes, indicating that the bond fission channel (1a) and the roaming channel (1b) are indeed the only active channels at the temperature and pressure ranges of the present experiments. The predicted reaction exo- and endothermicities are in excellent agreement with the current version of the Active Thermochemical Tables. Master equation calculations incorporating these transition state theory results yield predictions for the temperature and pressure dependence of the dissociation rate constants for channel 1a. The final theoretical results reliably reproduce the measured dissociation rate constants that are reported here and in the literature. The experimental data are well reproduced over the 500-2500 K and 1 x 10{sup -4} to 100 bar range (errors of {approx}15% or less) by the following Troe parameters for Ar as the bath gas: k{sub {infinity}} = 1.55 x 10{sup 24}T{sup -2.034} exp(-45490/T) s{sup -1}, k{sub 0} = 7.92 x 10{sup 53}T{sup -16.67} exp(-50380/T) cm{sup 3} s{sup -1}, and F{sub c} = 0.190 exp(-T/3091) + 0.810 exp(-T/128) + exp(-8829/T).

Process for using preferential physical solvents for selective processing of hydrocarbon gas streams  

SciTech Connect

This patent describes a process for the removal of hydrocarbon gas liquids, comprising hydrocarbons heavier than methane, from a hydrocarbon gas stream, wherein a need exists for recovering to any selected degree and at extremely high recoveries a selected hydrocarbon component and heavier hydrocarbons. The hydrocarbons are within the group consisting of ethane, propane, butane, and pentane without the need simultaneously to recover hydrocarbons lighter than the selected hydrocarbon component from the hydrocarbon gas stream, The improvement of selectively extracting the hydrocarbon gas liquids from the hydrocarbon gas stream with a preferential physical solvent is described here. The method provides selective capability for recovery according to the selected degree of (a) ethane in amounts ranging from 2-98%, (b) propane in amounts ranging from 2-99%, (c) butane in amounts ranging from 2-100%, or (d) pentanes and higher molecular weight hydrocarbons in amounts ranging up to 100%.

Power spectral density estimation for wireless fluctuation enhanced gas sensor nodes  

E-Print Network (OSTI)

Fluctuation enhanced sensing (FES) is a promising method to improve the selectivity and sensitivity of semiconductor and nanotechnology gas sensors. Most measurement setups include high cost signal conditioning and data acquisition units as well as intensive data processing. However, there are attempts to reduce the cost and energy consumption of the hardware and to find efficient processing methods for low cost wireless solutions. In our paper we propose highly efficient signal processing methods to analyze the power spectral density of fluctuations. These support the development of ultra-low-power intelligent fluctuation enhanced wireless sensor nodes while several further applications are also possible.

A comparison of advanced distillation control techniques for a propylene/propane splitter  

SciTech Connect

A detailed dynamic simulator of a propylene/propane (C{sub 3}) splitter, which was bench-marked against industrial data, has been used to compare dual composition control performance for a diagonal PI controller and several advanced controllers. The advanced controllers considered are DMC, nonlinear process model based control, and artificial neural networks. Each controller was tuned based upon setpoint changes in the overhead production composition using 50% changes in the impurity levels. Overall, there was not a great deal of difference in controller performance based upon the setpoint and disturbance tests. Periodic step changes in feed composition were also used to compare controller performance. In this case, oscillatory variations of the product composition were observed and the variabilities of the DMC and nonlinear process model based controllers were substantially smaller than that of the PI controller. The sensitivity of each controller to the frequency of the periodic step changes in feed composition was also investigated.

Cross sections for electron scattering by propane in the low- and intermediate-energy ranges  

SciTech Connect

We present a joint theoretical-experimental study on electron scattering by propane (C{sub 3}H{sub 8}) in the low- and intermediate-energy ranges. Calculated elastic differential, integral, and momentum transfer as well as total (elastic + inelastic) and total absorption cross sections are reported for impact energies ranging from 2 to 500 eV. Also, experimental absolute elastic cross sections are reported in the 40- to 500-eV energy range. A complex optical potential is used to represent the electron-molecule interaction dynamics. A theoretical method based on the single-center-expansion close-coupling framework and corrected by the Pade approximant is used to solve the scattering equations. The experimental angular distributions of the scattered electrons are converted to absolute cross sections using the relative flow technique. The comparison of our calculated with our measured results, as well as with other experimental and theoretical data available in the literature, is encouraging.

Well log evaluation of natural gas hydrates  

SciTech Connect

Gas hydrates are crystalline substances composed of water and gas, in which a solid-water-lattice accommodates gas molecules in a cage-like structure. Gas hydrates are globally widespread in permafrost regions and beneath the sea in sediment of outer continental margins. While methane, propane, and other gases can be included in the clathrate structure, methane hydrates appear to be the most common in nature. The amount of methane sequestered in gas hydrates is probably enormous, but estimates are speculative and range over three orders of magnitude from about 100,000 to 270,000,000 trillion cubic feet. The amount of gas in the hydrate reservoirs of the world greedy exceeds the volume of known conventional gas reserves. Gas hydrates also represent a significant drilling and production hazard. A fundamental question linking gas hydrate resource and hazard issues is: What is the volume of gas hydrates and included gas within a given gas hydrate occurrence? Most published gas hydrate resource estimates have, of necessity, been made by broad extrapolation of only general knowledge of local geologic conditions. Gas volumes that may be attributed to gas hydrates are dependent on a number of reservoir parameters, including the areal extent ofthe gas-hydrate occurrence, reservoir thickness, hydrate number, reservoir porosity, and the degree of gas-hydrate saturation. Two of the most difficult reservoir parameters to determine are porosity and degreeof gas hydrate saturation. Well logs often serve as a source of porosity and hydrocarbon saturation data; however, well-log calculations within gas-hydrate-bearing intervals are subject to error. The primary reason for this difficulty is the lack of quantitative laboratory and field studies. The primary purpose of this paper is to review the response of well logs to the presence of gas hydrates.

Variability in natural gas fuel composition and its effects on the performance of catalytic combustion systems. Final report for period September 18, 1998 - September 17, 2000  

SciTech Connect

Natural gas is composed primarily of methane with small amounts of higher hydrocarbons and diluents, which vary by region and over time. Compositions of natural gas from domestic and worldwide sources were surveyed with respect to content of higher hydrocarbons and diluents. The survey showed slight compositional variability between most of the gases, with a small fraction of them containing significantly larger contents of higher hydrocarbons than the mean. As gas-fired turbines will be used for power generation all over the world, they will need to tolerate operation with fuels with a wide variety of compositions, particularly with respect to the concentration of higher hydrocarbons and diluents. Subscale catalytic combustion modules typical of those used in gas turbine power generation with ultra low emissions of pollutants were tested in a subscale test system with natural gas alone and with added known levels of hydrocarbon compounds and diluents. The range of compositions tested contained the range observed in the survey. Test results were used to calculate the effect of composition on catalyst performance. The compositional variability is of little consequence to the catalyst for most of the gases in the survey, including nearly all of the gases delivered in the U.S. To accommodate the remaining gases, the catalyst inlet temperature must be lowered to maintain combustor durability. These results support commercial acceptance of catalytic combustion systems for use in natural gas fired turbines in distributed power generation with ultra low NO{sub x} emissions.

Adsorption of propane, isopropyl, and hydrogen on cluster models of the M1 phase of Mo-V-Te-Nb-O mixed metal oxide catalyst  

SciTech Connect

The Mo-V-Te-Nb-O mixed metal oxide catalyst possessing the M1 phase structure is uniquely capable of directly converting propane into acrylonitrile. However, the mechanism of this complex eight-electron transformation, which includes a series of oxidative H-abstraction and N-insertion steps, remains poorly understood. We have conducted a density functional theory study of cluster models of the proposed active and selective site for propane ammoxidation, including the adsorption of propane, isopropyl (CH{sub 3}CHCH{sub 3}), and H which are involved in the first step of this transformation, that is, the methylene C-H bond scission in propane, on these active site models. Among the surface oxygen species, the telluryl oxo (Te=O) is found to be the most nucleophilic. Whereas the adsorption of propane is weak regardless of the MO{sub x} species involved, isopropyl and H adsorption exhibits strong preference in the order of Te=O > V=O > bridging oxygens > empty Mo apical site, suggesting the importance of TeO{sub x} species for H abstraction. The adsorption energies of isopropyl and H and consequently the reaction energy of the initial dehydrogenation of propane are strongly dependent on the number of ab planes included in the cluster, which points to the need to employ multilayer cluster models to correctly capture the energetics of surface chemistry on this mixed metal oxide catalyst.

Operation of a Four-Cylinder 1.9L Propane Fueled HCCI Engine  

SciTech Connect

A four-cylinder 1.9 Volkswagen TDI Engine has been converted to run in Homogeneous Charge Compression Ignition (HCCI) mode. The stock configuration is a turbocharged direct injection Diesel engine. The combustion chamber has been modified by discarding the in-cylinder Diesel fuel injectors and replacing them with blank inserts (which contain pressure transducers). The stock pistons contain a reentrant bowl and have been retained for the tests reported here. The intake and exhaust manifolds have also been retained, but the turbocharger has been removed. A heater has been installed upstream of the intake manifold and fuel is added just downstream of this heater. The performance of this engine in naturally aspirated HCCI operation, subject to variable intake temperature and fuel flow rate, has been studied. The engine has been run with propane fuel at a constant speed of 1800 rpm. This work is intended to characterize the HCCI operation of the engine in this configuration that has been minimally modified from the base Diesel engine. The performance (BMEP, IMEP, efficiency, etc) and emissions (THC, CO, NOx) of the engine are presented, as are combustion process results based on heat release analysis of the pressure traces from each cylinder.

Autoignited laminar lifted flames of propane in coflow jets with tribrachial edge and mild combustion  

SciTech Connect

Characteristics of laminar lifted flames have been investigated experimentally by varying the initial temperature of coflow air over 800 K in the non-premixed jets of propane diluted with nitrogen. The result showed that the lifted flame with the initial temperature below 860 K maintained the typical tribrachial structure at the leading edge, which was stabilized by the balance mechanism between the propagation speed of tribrachial flame and the local flow velocity. For the temperature above 860 K, the flame was autoignited without having any external ignition source. The autoignited lifted flames were categorized in two regimes. In the case with tribrachial edge structure, the liftoff height increased nonlinearly with jet velocity. Especially, for the critical condition near blowout, the lifted flame showed a repetitive behavior of extinction and reignition. In such a case, the autoignition was controlled by the non-adiabatic ignition delay time considering heat loss such that the autoignition height was correlated with the square of the adiabatic ignition delay time. In the case with mild combustion regime at excessively diluted conditions, the liftoff height increased linearly with jet velocity and was correlated well with the square of the adiabatic ignition delay time.

Modeling of the formation of short-chain acids in propane flames  

E-Print Network (OSTI)

In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of propane stabilized at atmospheric pressure with nitrogen as diluent have been performed. It was found that amounts up to 25 ppm of acetic acid, 15 ppm of formic acid and 1 ppm of C3 acid can be formed for some positions in the flames. Simulations showed that the more abundant C3 acid formed is propenic acid. A quite acceptable agreement has been obtained with the scarce results from the literature concerning oxygenated compounds, including aldehydes (CH2O, CH3CHO) and acids. A reaction pathways analysis demonstrated that each acid is mainly derived from the aldehyde of similar structure.

Subnanometer platinum clusters highly active and selective catalysts for the oxidative dehydrogenation of propane.  

SciTech Connect

Small clusters are known to possess reactivity not observed in their bulk analogues, which can make them attractive for catalysis. Their distinct catalytic properties are often hypothesized to result from the large fraction of under-coordinated surface atoms. Here, we show that size-preselected Pt{sub 8-10} clusters stabilized on high-surface-area supports are 40-100 times more active for the oxidative dehydrogenation of propane than previously studied platinum and vanadia catalysts, while at the same time maintaining high selectivity towards formation of propylene over by-products. Quantum chemical calculations indicate that under-coordination of the Pt atoms in the clusters is responsible for the surprisingly high reactivity compared with extended surfaces. We anticipate that these results will form the basis for development of a new class of catalysts by providing a route to bond-specific chemistry, ranging from energy-efficient and environmentally friendly synthesis strategies to the replacement of petrochemical feedstocks by abundant small alkanes.

Analysis of natural gas supply strategies at Fort Drum  

SciTech Connect

This analysis investigates strategies for Fort Drum to acquire a reliable natural gas supply while reducing its gas supply costs. The purpose of this study is to recommend an optimal supply mix based on the life-cycle costs of each strategy analyzed. In particular, this study is intended to provide initial guidance as to whether or not the building and operating of a propane-air mixing station is a feasible alternative to the current gas acquisition strategy. The analysis proceeded by defining the components of supply (gas purchase, gas transport, supplemental fuel supply); identifying alternative options for each supply component; constructing gas supply strategies from different combinations of the options available for each supply component and calculating the life-cycle costs of each supply strategy under a set of different scenarios reflecting the uncertainty of future events.

Lithium bromide absorption chiller passes gas conditioning field test  

SciTech Connect

A lithium bromide absorption chiller has been successfully used to provide refrigeration for field conditioning of natural gas. The intent of the study was to identify a process that could provide a moderate level of refrigeration necessary to meet the quality restrictions required by natural-gas transmission companies, minimize the initial investment risk, and reduce operating expenses. The technology in the test proved comparatively less expensive to operate than a propane refrigeration plant. Volatile product prices and changes in natural-gas transmission requirements have created the need for an alternative to conventional methods of natural-gas processing. The paper describes the problems with the accumulation of condensed liquids in pipelines, gas conditioning, the lithium bromide absorption cycle, economics, performance, and operating and maintenance costs.

ED-XAS Data Reveal In-situ Time-Resolved Adsorbate Coverage on Supported Molybdenum Oxide Catalysts during Propane Dehydrogenation  

SciTech Connect

Energy-Dispersive X-ray Absorption Spectroscopy (ED-XAS) data combined with UV/Vis, Raman, and mass spectrometry data on alumina- and silica-supported molybdenum oxide catalysts under propane dehydrogenation conditions have been previously reported. A novel {delta}{mu} adsorbate isolation technique was applied here to the time-resolved (0.1 min) Mo K-edge ED-XAS data by taking the difference of absorption, {mu}, at t>1 against the initial time, t=0. Further, full multiple scattering calculations using the FEFF 8.0 code are performed to interpret the {delta}{mu} signatures. The resulting difference spectra and interpretation provide real time propane coverage and O depletion at the MoOn surface. The propane coverage is seen to correlate with the propene and/or coke production, with the maximum coke formation occurring when the propane coverage is the largest. Combined, these data give unprecedented insight into the complicated dynamics for propane dehydrogenation.

Efficiency Improvement Opportunities for Light-Duty Natural-Gas-Fueled Vehicles  

SciTech Connect

The purpose of this report is to evaluate and make recommendations concerning technologies that promise to improve the efilciency of compressed natural gas (CNG) light-duty vehicles. Technical targets for CNG automotive technology given in the March 1998 OffIce of Advanced Automotive Technologies research and development plan were used as guidance for this effort. The technical target that necessitates this current study is to validate technologies that enable CNG light vehicles to have at least 10% greater - fuel economy (on a miles per gallon equivalent basis) than equivalent gasoline vehicles by 2006. Other tar- gets important to natural gas (NG) automotive technology and this study are to: (1) increase CNG vehicle range to 380 miles, (2) reduce the incremental vehicle cost (CNG vs gasoline) to $1500, and (3) meet the California ultra low-emission vehicle (ULEV) and Federal Tier 2 emission standards expected to be in effect in 2004.

Thermogenic and secondary biogenic gases, San Juan Basin, Colorado and New Mexico - Implications for coalbed gas producibility  

SciTech Connect

The objectives of this paper are to (1) describe the types and the major components of coalbed gases, (2) evaluate the variability of Fruitland coalbed gas composition across the basin, (3) assess factors affecting coalbed gas origin and composition, (4) determine the timing and extent of gas migration and entrapment, and (5) suggest application of these results to coalbed gas producibility. Data from more than 750 Fruitland coalbed gas wells were used to make gas-composition maps and to evaluate factors controlling gas origin. The gas data were divided into overpressured, underpressured, and transitional categories based on regional pressure regime. Also, [delta][sup 13]C isotopic values from 41 methane, 7 ethane and propane, 13 carbon dioxide, and 10 formation-water bicarbonate samples were evaluated to interpret gas origin. The data suggests that only 25-50% of the gas produced in the high-productivity fairway was generated in situ during coalification. 82 refs., 14 figs., 3 tabs.

High-Pressure Micellar Solutions of Polystyrene-block-Polybutadiene and Polystyrene-block-Polyisoprene Solutions in Propane Exhibit Cloud-Pressure Reduction and Distinct Micellization End Points  

SciTech Connect

Micellar solutions of polystyrene-block-polybutadiene and polystyrene-block-polyisoprene in propane are found to exhibit significantly lower cloud pressures than the corresponding hypothetical non-micellar solutions. Such a cloud-pressure reduction indicates the extent to which micelle formation enhances the apparent diblock solubility in near-critical and hence compressible propane. Pressure-temperature points beyond which no micelles can be formed, referred to as the micellization end points, are found to depend on the block type, size and ratio, and on the polymer concentration. For a given pressure, the micellization end-point temperature corresponds to the "critical micelle temperature." The cloud-pressure reduction and the micellization end point measured for styrene-diene diblocks in propane should be characteristic of all amphiphilic diblock copolymer solutions that form micelles in compressible solvents.

Synergistic effect of mixing dimethyl ether with methane, ethane, propane, and ethylene fuels on polycyclic aromatic hydrocarbon and soot formation  

SciTech Connect

Characteristics of polycyclic aromatic hydrocarbon (PAH) and soot formation in counterflow diffusion flames of methane, ethane, propane, and ethylene fuels mixed with dimethyl ether (DME) have been investigated. Planar laser-induced incandescence and fluorescence techniques were employed to measure relative soot volume fractions and PAH concentrations, respectively. Results showed that even though DME is known to be a clean fuel in terms of soot formation, DME mixture with ethylene fuel increases PAH and soot formation significantly as compared to the pure ethylene case, while the mixture of DME with methane, ethane, and propane decreases PAH and soot formation. Numerical calculations adopting a detailed kinetics showed that DME can be decomposed to produce a relatively large number of methyl radicals in the low-temperature region where PAH forms and grows; thus the mixture of DME with ethylene increases CH{sub 3} radicals significantly in the PAH formation region. Considering that the increase in the concentration of O radicals is minimal in the PAH formation region with DME mixture, the enhancement of PAH and soot formation in the mixture flames of DME and ethylene can be explained based on the role of methyl radicals in PAH and soot formation. Methyl radicals can increase the concentration of propargyls, which could enhance incipient benzene ring formation through the propargyl recombination reaction and subsequent PAH growth. Thus, the result substantiates the importance of methyl radicals in PAH and soot formation, especially in the PAH formation region of diffusion flames. (author)

Experimental and kinetic study of autoignition in methane/ethane/air and methane/propane/air mixtures under engine-relevant conditions  

SciTech Connect

The ignition delay of homogeneous methane/air mixtures enriched with small fractions of ethane/propane was measured using the reflected-shock technique at temperatures from 900 to 1400 K and pressures from 16 to 40 bar. The results show complex effects of ethane/propane on the ignition of methane, but a common trend observed with both hydrocarbons is an increased promotion effect for temperatures below 1100 K. A detailed kinetic mechanism was used to investigate the interaction between ethane/propane and the ignition chemistry of methane under the above conditions. It was found that at relatively low temperatures, the reactions between ethane/propane and methylperoxy (CH{sub 3}O{sub 2}) lead to an enhanced rate of formation of OH radicals in the initiation phase of the ignition. By systematically applying the quasi-steady-state assumptions to the intermediate species involved in the main reaction path identified, we have achieved an analytical description of the ignition process in the transitional temperature regime. The analytical solutions agree reasonably well with the detailed kinetic model and the experimental results for both ignition delay and concentrations of major intermediate species.

An In-Situ XAS Study of the Structural Changes in a CuO-CeO2/Al2O3 Catalyst during Total Oxidation of Propane  

SciTech Connect

A CuOx-CeOx/Al2O3 catalyst was studied with in-situ transmission Cu K XAS for the total oxidation of propane as model reaction for the catalytic elimination of volatile organic compounds. The local Cu structure was determined for the catalyst as such, after pre-oxidation and after reduction with propane. The catalyst as such has a local CuO structure. No structural effect was observed upon heating in He up to 600 deg. C or after pre-oxidation at 150 deg. C. A full reduction of the Cu2+ towards metallic Cu0 occurred, when propane was fed to the catalyst. The change in local Cu structure during propane reduction was followed with a time resolution of 1 min. The {chi}(k) scans appeared as linear combinations of start and end spectra, CuO and Cu structure, respectively. However, careful examination of the XANES edge spectra indicates the presence of a small amount of additional Cu1+ species.

Cracking of simulated oil refinery off-gas over a coal char, petroleum coke, and quartz  

SciTech Connect

The cracking of oil refinery off-gas, simulated with a gas mixture containing methane (51%), ethylene (21.4%), ethane (21.1%), and propane (6.5%), over a coal char, petroleum coke, and quartz, respectively, has been studied in a fixed bed reactor. The experiments were performed at temperatures between 850 and 1000{sup o}C and at atmospheric pressure. The results show that the conversions of all species considered increased with increasing temperature. Ethane and propane completely decomposed over all three bed materials in the temperature range investigated. However, the higher initial conversion rates of methane and ethylene cracking at all temperatures were observed only over the coal char and not on the petroleum coke and quartz, indicating a significant catalytic effect of the coal char on methane and ethylene cracking. Methane and ethylene conversions decreased with reaction time due to deactivation of the coal char by carbon deposition on the char surface and, in the later stage of a cracking experiment, became negative, suggesting that methane and ethylene had been formed during the cracking of ethane and propane. 16 refs., 13 figs., 2 tabs.

Impact of Fuel Interchangeability on dynamic Instabilities in Gas Turbine Engines  

SciTech Connect

Modern, low NOx emitting gas turbines typically utilize lean pre-mixed (LPM) combustion as a means of achieving target emissions goals. As stable combustion in LPM systems is somewhat intolerant to changes in operating conditions, precise engine tuning on a prescribed range of fuel properties is commonly performed to avoid dynamic instabilities. This has raised concerns regarding the use of imported liquefied natural gas (LNG) and natural gas liquids (NGL’s) to offset a reduction in the domestic natural gas supply, which when introduced into the pipeline could alter the fuel BTU content and subsequently exacerbate problems such as combustion instabilities. The intent of this study is to investigate the sensitivity of dynamically unstable test rigs to changes in fuel composition and heat content. Fuel Wobbe number was controlled by blending methane and natural gas with various amounts of ethane, propane and nitrogen. Changes in combustion instabilities were observed, in both atmospheric and pressurized test rigs, for fuels containing high concentrations of propane (> 62% by vol). However, pressure oscillations measured while operating on typical “LNG like” fuels did not appear to deviate significantly from natural gas and methane flame responses. Mechanisms thought to produce changes in the dynamic response are discussed.

Compressible Solution Properties of Amorphous Polystyrene-block-Polybutadiene, Crystalline Polystyrene-block-Poly(Hydrogenated Polybutadiene) and Their Corresponding Homopolymers: Fluid-Fluid, Fluid-Solid and Fluid-Micelle Phase Transitions in Propane and Propylene  

SciTech Connect

Abstract Polystyrene, polybutadiene, hydrogenated polybutadiene, and styrene diblock copolymers of these homopolymers can form homogenous solutions in compressible solvents, such as propane and propylene, which separate into two bulk phases upon reducing pressure. The cloud and micellization pressures for homopolymer and diblock copolymers are generally found to be higher in propane than in propylene, except for hydrogenated polybutadiene and polystyrene-block-(hydrogenated polybutadiene). Hydrogenated polybutadiene homopolymers and copolymers exhibit relatively pressure-independent crystallization and melting observed in both propane and propylene solutions.
