Process for producing carbon monoxide and hydrogen from methanol  

SciTech Connect (OSTI)

A process is described for producing carbon monoxide and hydrogen which comprises contacting methanol vapor at a temperature of 200 degrees to 300 degrees C with an indirectly heated zinc containing catalyst to obtain an effluent gas in which the components of carbon monoxide and hydrogen constitute at least 90% by volume of said gas. At least a part of the impurities from said effluent gas are removed and said effluent gas is deparated into its carbon monoxide and hydrogen components by adsorption. The effluent gas can be separated into its carbon monoxide and hydrogen components by use of a plurality of adsorbers containing zeolite-type molecular sieve material where the zeolite is substantially permeable to hydrogen but sorbs carbon monoxide.

Mechanism of methanol synthesis from carbon monoxide and hydrogen on copper catalysts  

SciTech Connect (OSTI)

The authors examine possible mechanisms of methanol synthesis from carbon monoxide and hydrogen on supported copper catalysts. Two broad categories of reaction mechanism can be identified: (a) Type I: Carbon monoxide, adsorbed on the copper surface, is hydrogenated by the addition of hydrogen atoms while the C-O bond remains intact. A second C-O bond is neither formed nor broken. (b) Type II: Carbon monoxide (or a partially hydrogenated intermediate, e.g., HCO) reacts with an oxygen atom on the catalyst surface to give an intermediate, typically a formate, which contains two C-O bonds. Subsequent reaction leads overall to methanol and the reformation of the surface oxygen atom. Both mechanisms are discussed.

Carbon dioxide hydrogenation to form methanol via a reverse-water-gas-shift reaction (the CAMERE process)  

SciTech Connect (OSTI)

The CAMERE process (carbon dioxide hydrogenation to form methanol via a reverse-water-gas-shift reaction) was developed and evaluated. The reverse-water-gas-shift reactor and the methanol synthesis reactor were serially aligned to form methanol from CO{sub 2} hydrogenation. Carbon dioxide was converted to CO and water by the reverse-water-gas-shift reaction (RWReaction) to remove water before methanol was synthesized. With the elimination of water by RWReaction, the purge gas volume was minimized as the recycle gas volume decreased. Because of the minimum purge gas loss by the pretreatment of RWReactor, the overall methanol yield increased up to 89% from 69%. An active and stable catalyst with the composition of Cu/ZnO/ZrO{sub 2}/Ga{sub 2}O{sub 3} (5:3:1:1) was developed. The system was optimized and compared with the commercial methanol synthesis processes from natural gas and coal.

A Theoretical Study of Methanol Synthesis from CO(2) Hydrogenation on Metal-doped Cu(111) Surfaces  

SciTech Connect (OSTI)

Density functional theory (DFT) calculations and Kinetic Monte Carlo (KMC) simulations were employed to investigate the methanol synthesis reaction from CO{sub 2} hydrogenation (CO{sub 2} + 3H{sub 2} {yields} CH{sub 3}OH + H{sub 2}O) on metal-doped Cu(111) surfaces. Both the formate pathway and the reverse water-gas shift (RWGS) reaction followed by a CO hydrogenation pathway (RWGS + CO-Hydro) were considered in the study. Our calculations showed that the overall methanol yield increased in the sequence: Au/Cu(111) < Cu(111) < Pd/Cu(111) < Rh/Cu(111) < Pt/Cu(111) < Ni/Cu(111). On Au/Cu(111) and Cu(111), the formate pathway dominates the methanol production. Doping Au does not help the methanol synthesis on Cu(111). Pd, Rh, Pt, and Ni are able to promote the methanol production on Cu(111), where the conversion via the RWGS + CO-Hydro pathway is much faster than that via the formate pathway. Further kinetic analysis revealed that the methanol yield on Cu(111) was controlled by three factors: the dioxomethylene hydrogenation barrier, the CO binding energy, and the CO hydrogenation barrier. Accordingly, two possible descriptors are identified which can be used to describe the catalytic activity of Cu-based catalysts toward methanol synthesis. One is the activation barrier of dioxomethylene hydrogenation, and the other is the CO binding energy. An ideal Cu-based catalyst for the methanol synthesis via CO{sub 2} hydrogenation should be able to hydrogenate dioxomethylene easily and bond CO moderately, being strong enough to favor the desired CO hydrogenation rather than CO desorption but weak enough to prevent CO poisoning. In this way, the methanol production via both the formate and the RWGS + CO-Hydro pathways can be facilitated.

An Analysis of Methanol and Hydrogen Production via High-Temperature Electrolysis Using the Sodium Cooled Advanced Fast Reactor  

SciTech Connect (OSTI)

Integration of an advanced, sodium-cooled fast spectrum reactor into nuclear hybrid energy system (NHES) architectures is the focus of the present study. A techno-economic evaluation of several conceptual system designs was performed for the integration of a sodium-cooled Advanced Fast Reactor (AFR) with the electric grid in conjunction with wind-generated electricity. Cases in which excess thermal and electrical energy would be reapportioned within an integrated energy system to a chemical plant are presented. The process applications evaluated include hydrogen production via high temperature steam electrolysis and methanol production via steam methane reforming to produce carbon monoxide and hydrogen which feed a methanol synthesis reactor. Three power cycles were considered for integration with the AFR, including subcritical and supercritical Rankine cycles and a modified supercritical carbon dioxide modified Brayton cycle. The thermal efficiencies of all of the modeled power conversions units were greater than 40%. A thermal efficiency of 42% was adopted in economic studies because two of the cycles either performed at that level or could potentially do so (subcritical Rankine and S-CO2 Brayton). Each of the evaluated hybrid architectures would be technically feasible but would demonstrate a different internal rate of return (IRR) as a function of multiple parameters; all evaluated configurations showed a positive IRR. As expected, integration of an AFR with a chemical plant increases the IRR when must-take wind-generated electricity is added to the energy system. Additional dynamic system analyses are recommended to draw detailed conclusions on the feasibility and economic benefits associated with AFR-hybrid energy system operation.

Fuel processor for fuel cell power system. [Conversion of methanol into hydrogen  

DOE Patents [OSTI]

A catalytic organic fuel processing apparatus, which can be used in a fuel cell power system, contains within a housing a catalyst chamber, a variable speed fan, and a combustion chamber. Vaporized organic fuel is circulated by the fan past the combustion chamber with which it is in indirect heat exchange relationship. The heated vaporized organic fuel enters a catalyst bed where it is converted into a desired product such as hydrogen needed to power the fuel cell. During periods of high demand, air is injected upstream of the combustion chamber and organic fuel injection means to burn with some of the organic fuel on the outside of the combustion chamber, and thus be in direct heat exchange relation with the organic fuel going into the catalyst bed.

Methanol Synthesis from CO2 Hydrogenation over a Pd4/In2O3 Model Catalyst: A Combined DFT and Kinetic Study  

SciTech Connect (OSTI)

Methanol synthesis from CO2 hydrogenation on Pd4/In2O3 has been investigated using density functional theory (DFT) and microkinetic modeling. In this study, three possible routes in the reaction network of CO2 + H2 ? CH3OH + H2O have been examined. Our DFT results show that the HCOO route competes with the RWGS route whereas a high activation barrier kinetically blocks the HCOOH route. DFT results also suggest that H2COO* + H* ? H2CO* +OH* and cis-COOH* + H* ?CO* + H2O* are the rate limiting steps in the HCOO route and the RWGS route, respectively. Microkinetic modeling results demonstrate that the HCOO route is the dominant reaction route for methanol synthesis from CO2 hydrogenation. We found that the activation of H adatom on the small Pd cluster and the presence of H2O on the In2O3 substrate play important roles in promoting the methanol synthesis. The hydroxyl adsorbed at the interface of Pd4/In2O3 induces the transformation of the supported Pd4 cluster from a butterfly structure into a tetrahedron structure. This important structure change not only indicates the dynamical nature of the supported nanoparticle catalyst structure during the reaction but also shifts the final hydrogenation step from H2COH to CH3O.

Selective production of hydrogen for fuel cells via oxidative steam reforming of methanol over CuZnAl(Zr)-oxide catalysts  

Science Journals Connector (OSTI)

Fuel cell powered vehicles using hydrogen (H2) as a fuel are currently being developed in an effort to mitigate the emissions of green house gases such as CO2, NOx, and hydrocarbons. The H2 fuel is extracted from methanol onboard a vehicle by steam reforming of methanol (SRM) reaction. A considerable amount of CO is produced as a by-product, which is a poison to the Pt anode of the fuel cell. Very recently, we have demonstrated that a combined SRM and partial oxidation of methanol (POM), which we labeled as oxidative steam reforming of methanol (OSRM) reaction is more efficient for the selective production of H2 relatively at a lower temperature of around 230C over CuZnAl(Zr)-oxide catalysts derived from hydroxycarbonate precursors containing hydrotalcite (HT)-like layered double hydroxides (LDHs)/aurichalcite phases. There are several operating parameters such as catalyst composition, reaction temperature, O2/CH3OH and H2O/CH3OH molar ratios and methanol injection rate that are need to be optimized in order to produce H2 suitable for fuelling a fuel cell. In the present study, we have investigated the effect of these variable parameters on the catalytic performance over a series of CuZnAl- and CuZnAlZr-oxide catalysts. Our study indicated that among the CuZn-based catalysts, those containing Zr were the most active. The optimum O2/CH3OH and H2O/CH3OH molar ratios should be in the ranges 0.200.30 and 1.31.6, respectively, in order to achieve a better catalytic performance. Studies of the effect of methanol contact time on the catalytic performance over a Zr-containing catalyst revealed that the OSRM reaction proceeds through the formation of formaldehyde intermediate. CO was produced as a secondary product by the decomposition of formaldehyde and it is subsequently transformed into CO2 and H2 by the water-gas shift (WGS) reaction.

Abstract Cu was loaded on the S-doped TiO2 by electroless plating method. The prepared Cu/STiO2 exhibited high photocatalytic activity for hydrogen generation, and the yield is up to 7.5mmolh?1g?1cat in methanol solution. Their physical structure and chemical properties were characterized by UVVis, XRD, XPS and EXAFS. The copper species were CuO and Cu2O, and the sample showed excellent visible light absorption ability. Comparing with the sample prepared by chemical reducing method, the electroless plated copper on STiO2 was highly dispersed, which could facilitate photo-generated charges capture, transfer and separation.

Rapid system start-up is accomplished by a combination of direct and indirect heating of the cracking catalyst. Initially, liquid methanol is burned with a stoichiometric or slightly lean air mixture in the combustion chamber of the reactor assembly. The hot combustion gas travels down a flue gas chamber in heat exchange relationship with the catalytic cracking chamber transferring heat across the catalyst chamber wall to heat the catalyst indirectly. The combustion gas is then diverted back through the catalyst bed to heat the catalyst pellets directly. When the cracking reactor temperature reaches operating temperature, methanol combustion is stopped and a hot gas valve is switched to route the flue gas overboard, with methanol being fed directly to the catalytic cracking reactor. Thereafter, the burner operates on excess hydrogen from the fuel cells.

Role of the zeolitic environment in catalytic activation of methanol  

SciTech Connect (OSTI)

One of the most significant industrial applications of zeolites exploits the ability of the microporous aluminosilicate environment to catalyze the methanol to gasoline (MTG) process. The industrial process proceeds at elevated temperatures ({approximately} 700 K) and methanol pressures which correspond to a loading of {approximately} 5--6 methanol molecules per acidic hydroxyl group, which is believed to be the active site. The authors present an extensive study of the initial stages of the methanol to gasoline conversion in the framework of the ab initio molecular dynamics approach. They investigate the effect of different zeolite environments, methanol loading, and temperature and show that, for understanding the initial adsorption and activation of the adsorbed species, all three factors need to be considered simultaneously. The results allow them to develop a simple model for the activation of the methanol molecule, which elucidates the role of both the zeolite framework and the methanol solvent. The zeolite framework plays an active role in methanol protonation. The solvent significantly softens the C-O bond of the methoxonium, rendering it very anharmonic. High mobility of the methoxonium cation, promoted by some zeolite frameworks, prevents it from forming hydrogen bonds with the active sites and the solvent leading to the activation of the methoxonium species. This picture is shown to be consistent with the experimental infrared spectra.

Advanced hydrogen utilization technology demonstration  

SciTech Connect (OSTI)

This report presents the results of a study done by Detroit Diesel Corporation (DDC). DDC used a 6V-92TA engine for experiments with hydrogen fuel. The engine was first baseline tested using methanol fuel and methanol unit injectors. One cylinder of the engine was converted to operate on hydrogen fuel, and methanol fueled the remaining five cylinders. This early testing with only one hydrogen-fueled cylinder was conducted to determine the operating parameters that would later be implemented for multicylinder hydrogen operation. Researchers then operated three cylinders of the engine on hydrogen fuel to verify single-cylinder idle tests. Once it was determined that the engine would operate well at idle, the engine was modified to operate with all six cylinders fueled with hydrogen. Six-cylinder operation on hydrogen provided an opportunity to verify previous test results and to more accurately determine the performance, thermal efficiency, and emissions of the engine.

Enzymatic conversion of carbon dioxide to methanol: Enhanced methanol production in silica sol-gel matrices  

SciTech Connect (OSTI)

Strategies for effective conversion of atmospheric CO{sub 2} to methanol offer promising new technologies not only for recycling of the greenhouse gas but also for an efficient production of fuel alternatives. Partial hydrogenation of carbon dioxide has been accomplished by means of heterogeneous catalysis, electrocatalysis, and photocatalysis. Oxide-based catalysts are predominantly used for industrial fixation of carbon dioxide. A unique approach in this direction involves the use of enzymes as catalysts for conversion of carbon dioxide to methanol. The use of enzymes is particularly appealing since it provides a facile low-temperature route for generation of methanol directly from gaseous carbon dioxide. The authors report an enzymatically coupled sequential reduction of carbon dioxide to methanol by using a series of reactions catalyzed by three different dehydrogenases. Overall, the process involves an initial reduction of CO{sub 2} to formate catalyzed by formate dehydrogenase (F{sub ate}DH), followed by reduction of formate to formaldehyde by formaldehyde dehydrogenase (F{sub ald}DH), and finally formaldehyde is reduced to methanol by alcohol dehydrogenase (ADH). In this process, reduced nicotinamide adenine dinucleotide (NADH) acts as a terminal electron donor for each dehydrogenase-catalyzed reduction.

The Methanol Economy Project  

SciTech Connect (OSTI)

The Methanol Economy Project is based on the concept of replacing fossil fuels with methanol generated either from renewable resources or abundant natural (shale) gas. The full methanol cycle was investigated in this project, from production of methanol through bromination of methane, bireforming of methane to syngas, CO{sub 2} capture using supported amines, co-electrolysis of CO{sub 2} and water to formate and syngas, decomposition of formate to CO{sub 2} and H{sub 2}, and use of formic acid in a direct formic acid fuel cell. Each of these projects achieved milestones and provided new insights into their respective fields. ? Direct electrophilic bromination of methane to methyl bromide followed by hydrolysis to yield methanol was investigated on a wide variety of catalyst systems, but hydrolysis proved impractical for large-scale industrial application. ? Bireforming the correct ratio of methane, CO{sub 2}, and water on a NiO / MgO catalyst yielded the right proportion of H{sub 2}:CO (2:1) and proved to be stable for at least 250 hours of operation at 400 psi (28 atm). ? CO{sub 2} capture utilizing supported polyethyleneimines yielded a system capable of adsorbing CO{sub 2} from the air and release at nominal temperatures with negligible amine leaching. ? CO{sub 2} electrolysis to formate and syngas showed considerable increases in rate and selectivity by performing the reaction in a high pressure flow electrolyzer. ? Formic acid was shown to decompose selectively to CO{sub 2} and H{sub 2} using either Ru or Ir based homogeneous catalysts. ? Direct formic acid fuel cells were also investigated and showed higher than 40% voltage efficiency using reduced loadings of precious metals. A technoeconomic analysis was conducted to assess the viability of taking each of these processes to the industrial scale by applying the data gathered during the experiments to approximations based on currently used industrial processes. Several of these processes show significant promise for industrial scale up and use towards improving our nations energy independence.

The Influence of Chain Dynamics on the Far Infrared Spectrum of Liquid Methanol-Water Mixtures  

SciTech Connect (OSTI)

Far-infrared absorption spectroscopy has been used to study the low frequency ({center_dot} 100 cm{sup -1}) intermolecular modes of methanol in mixtures with water. With the aid of a first principles molecular dynamics simulation on an equivalent system, a detailed understanding about the origin of the low frequency IR modes has been established. The total dipole spectrum from the simulation suggests that the bands appearing in the experimental spectra at approximately 55 cm{sup -1} and 70 cm{sup -1} in methanol and methanol-rich mixtures arise from both fluctuations and torsional motions occurring within the methanol hydrogen-bonded chains. The influence of these modes on both the solvation dynamics and the relaxation mechanisms in the liquid are discussed within the context of recent experimental and theoretical results that have emerged from studies focusing on the short time dynamics in the methanol hydrogen bond network.

The addition of methanol to a high-sulfidity kraft cook on Scandinavian softwood chips was studied under different process conditions. Delignification and the degradation of carbohydrates were accelerated, but the effect on delignification was greater. Thus, methanol addition improved selectivity. The positive effect of methanol could also be observed for modified kraft cooks having a leveled out alkali concentration and lower concentration of sodium ions and dissolved lignin at the end of the cook. Methanol addition had no discernible effect on pulp strength or on pulp bleachability.

In-situ characterization of adsorbed species on methanol synthesis catalysts by FT-IR spectroscopy  

SciTech Connect (OSTI)

Transmission infrared spectroscopy was used to characterize adsorbed species on methanol synthesis catalysts during reaction conditions. A copper carbonyl, bidentate formate, and methoxy species were identified as stable surface groups. An adsorbed formaldehyde species was unstable at the reaction temperature, but could be observed on the catalyst surface at the beginning of the reaction. Surface species were very similar for feed mixtures of 1) carbon monoxide and hydrogen, 2) carbon monoxide, carbon dioxide, and hydrogen, and 3) formic acid and hydrogen. The role of copper in methanol synthesis catalysts was to increase the adsorption of carbon monoxide to form a linear carbonyl species. This carbonly promoted the hydrogenation of formate groups. The formate species was adsorbed on a zinc site (Zn/sub ..beta../) different from the zinc site (Zn/sub ..gamma../) on which formaldehyde and methoxy groups were adsorbed. The rate-determining step in methanol synthesis was determined to be the reaction of hydrogen from a hydroxyl species adsorbed on another zinc site (Zn/sub ..cap alpha../) with a methoxy group to yield methanol. It was established that at the experimental conditions used in this study, the methanol synthesis reaction was far from equilibrium while the water-gas shift reaction was near equilibrium.

Methanol production with elemental phosphorus byproduct gas: technical and economic feasibility  

SciTech Connect (OSTI)

The technical and economic feasibility of using a typical, elemental, phosphorus byproduct gas stream in methanol production is assessed. The purpose of the study is to explore the potential of a substitute for natural gas. The first part of the study establishes economic tradeoffs between several alternative methods of supplying the hydrogen which is needed in the methanol synthesis process to react with CO from the off gas. The preferred alternative is the Battelle Process, which uses natural gas in combination with the off gas in an economically sized methanol plant. The second part of the study presents a preliminary basic design of a plant to (1) clean and compress the off gas, (2) return recovered phosphorus to the phosphorus plant, and (3) produce methanol by the Battelle Process. Use of elemental phosphorus byproduct gas in methanol production appears to be technically feasible. The Battelle Process shows a definite but relatively small economic advantage over conventional methanol manufacture based on natural gas alone. The process would be economically feasible only where natural gas supply and methanol market conditions at a phosphorus plant are not significantly less favorable than at competing methanol plants. If off-gas streams from two or more phosphorus plants could be combined, production of methanol using only offgas might also be economically feasible. The North American methanol market, however, does not seem likely to require another new methanol project until after 1990. The off-gas cleanup, compression, and phosphorus-recovery system could be used to produce a CO-rich stream that could be economically attractive for production of several other chemicals besides methanol.

Methanol conversion to higher hydrocarbons  

SciTech Connect (OSTI)

Several indirect options exist for producing chemicals and transportation fuels from coal, natural gas, or biomass. All involve an initial conversion step to synthesis gas (CO and H{sub 2}). Presently, there are two commercial technologies for converting syngas to liquids: Fischer-Tropsch, which yields a range of aliphatic hydrocarbons with molecular weights determined by Schulz-Flory kinetics, and methanol synthesis. Mobil`s diversity of technology for methanol conversion gives the methanol synthesis route flexibility for production of either gasoline, distillate or chemicals. Mobil`s ZSM-5 catalyst is the key in several processes for producing chemicals and transportation fuels from methanol: MTO for light olefins, MTG for gasoline, MOGD for distillates. The MTG process has been commercialized in New Zealand since 1985, producing one-third of the country`s gasoline supply, while MTO and MOGD have been developed and demonstrated at greater than 100 BPD scale. This paper will discuss recent work in understanding methanol conversion chemistry and the various options for its use.

ATOM-ECONOMICAL PATHWAYS TO METHANOL FUEL CELL FROM BIOMASS  

SciTech Connect (OSTI)

An economical production of alcohol fuels from biomass, a feedstock low in carbon and high in water content, is of interest. At Brookhaven National Laboratory (BNL), a Liquid Phase Low Temperature (LPLT) concept is under development to improve the economics by maximizing the conversion of energy carrier atoms (C,H) into energy liquids (fuel). So far, the LPLT concept has been successfully applied to obtain highly efficient methanol synthesis. This synthesis was achieved with specifically designed soluble catalysts, at temperatures < 150 C. A subsequent study at BNL yielded a water-gas-shift (WGS) catalyst for the production of hydrogen from a feedstock of carbon monoxide and H{sub 2}O at temperatures < 120 C. With these LPLT technologies as a background, this paper extends the discussion of the LPLT concept to include methanol decomposition into 3 moles of H{sub 2} per mole of methanol. The implication of these technologies for the atom-economical pathways to methanol fuel cell from biomass is discussed.

Methanol adsorption and decomposition on rhodium  

SciTech Connect (OSTI)

The decomposition of methanol on rhodium probed from {approximately}200 atomic sites of the (001) or (111) planes or Rh field emitter crystals but randomly with regard to crystallographic zones was studied by pulsed field desorption mass spectrometry. High electric field pulses were used to quantitatively desorb the final products, carbon monoxide and hydrogen, thus achieving steady-state conditions. Substantial amounts of methoxy (mainly desorbed as CH{sub 3}{sup +} ions) were also present at the surface. Applying a steady electric field, F{sub R} {ge} 4 V/nm, between the field pulses, led to a deceleration of the decomposition reaction and to increase of the amount of adsorbed CH{sub 3}O and CH{sub 2}O species. There were indicators that the rate-determining step of the reaction is C-H bond cleavage in adsorbed methoxy to form the CH{sub 2}O intermediate. This was supported by the observation of a kinetic isotope effect in the formation of CD{sub 2}O and CHDO from methyl-d{sub 2}-alcohol, CHD{sub 2}OH. Here, the C-H bond breaking to form the CD{sub 2}O was found to be twice as fast as the breaking of the C-D bond which results in CHDO. Field ion microscopy was applied to investigate the influence of the reaction on the structure of the whole hemispherical single crystal surface. There were neither topographic changes nor corrosion of the Rh surface after field-free exposure to 2 Pa methanol at temperatures up to 423 K.

Approaches to methanol-tolerant air cathodes for methanol-air fuel cells  

SciTech Connect (OSTI)

The achievement of truly methanol-tolerant oxygen cathodes will greatly assist the development of direct methanol-air fuel cells, because the cathode performance will not be affected by the presence of methanol or its oxidation products, which can diffuse across the cell from the anode. In addition, methanol will not be consumed at the cathode. Although platinum-based oxygen cathodes can continue to perform well in the presence of methanol under certain conditions, methanol can be consumed rapidly at such electrodes. Oxygen electrocatalysts were examined in the present work which are largely inactive for methanol oxidation and are also not affected significantly by the presence of methanol. These included heat-treated transition metal macrocycles and hydrated ruthenium dioxide. The most promising electrocatalyst examines thus far is heat-treated iron tetramethoxyphenylporphyrin supported on high area carbon.

Process for the conversion of carbonaceous feedstocks to particulate carbon and methanol  

DOE Patents [OSTI]

A process is described for the production of a pollutant-free particulate carbon (i.e., a substantially ash-, sulfur- and nitrogen-free carbon) from carbonaceous feedstocks. The basic process involves de-oxygenating one of the gas streams formed in a cyclic hydropyrolysis-methane pyrolysis process in order to improve conversion of the initial carbonaceous feedstock. De-oxygenation is effected by catalytically converting carbon monoxide, carbon dioxide, and hydrogen contained in one of the pyrolysis gas streams, preferably the latter, to a methanol co-product. There are thus produced two products whose use is known per se, viz., a substantially pollutant-free particulate carbon black and methanol. These products may be admixed in the form of a liquid slurry of carbon black in methanol. 3 figs.

Study of the methanol conversion to ethylene and propylene using small pore size zeolites  

SciTech Connect (OSTI)

This project consisted of the study of the kinetics of the reaction of methanol to olefins. A combined selectivity to ethylene and propylene of 90% is readily achieved by selecting a proper set of operating conditions. The investigation encompassed the study of external and internal diffusion, adsorption and reaction. Instantaneous and overall material balances were developed, and a minimization technique was used to calculate the rate of formation of coke, the amount of coke deposition on the catalyst, and the hydrogen to carbon ratio. This procedure allowed the adjustment of several parameters in order to satisfy the material balances. The results were used to calculate the rate constants of the proposed model. The results indicated that the dehydration of methanol was inhibited by the adsorption of methanol. In general low methanol partial pressures, achieved by decreasing the total pressure in the case of pure methanol feeds, or by diluting methanol with water or nitrogen, increased the selectivity toward olefins. All the catalysts studied showed deactivation due to the accumulation of aromatic compounds (coke), which had a hydrogen to carbon ration close to 1.1. The maximum amount of coke that can be deposited on the catalyst was about 0.16 grams coke/gram catalyst. The catalyst was regenerated by burning the coke with air. Residence time distribution experiments using a step input change showed that perfect mixing could be obtained with 200 grams of powder catalyst of 30-100 microns particle size by using flow rates smaller than 5 cc/sec measured at reactor conditions, and impeller speeds higher than 12 rev/sec.

Advanced direct methanol fuel cells. Final report  

SciTech Connect (OSTI)

The goal of the program was an advanced proton-exchange membrane (PEM) for use as the electrolyte in a liquid feed direct methanol fuel cell which provides reduced methanol crossover while simultaneously providing high conductivity and low membrane water content. The approach was to use a membrane containing precross-linked fluorinated base polymer films and subsequently to graft the base film with selected materials. Over 80 different membranes were prepared. The rate of methanol crossover through the advanced membranes was reduced 90%. A 5-cell stack provided stable performance over a 100-hour life test. Preliminary cost estimates predicted a manufacturing cost at $4 to $9 per kW.

Experimental investigation of methanol crossover evolution during direct methanol fuel cell degradation tests  

Science Journals Connector (OSTI)

Abstract Methanol crossover and severe degradation are two of the most critical issues hindering the commercialization of direct methanol fuel cells. The experimental investigations found in the literature show that degradation has both permanent and temporary contributions; the latter can be recovered thanks to a suitable operation interruption. This work reports the experimental characterization of methanol crossover and water content in cathode exhaust during different degradation tests performed in continuous and cycling operation modes. Such investigation evidences a reduction of methanol crossover during the DMFC degradation tests that can be partially restored. Methanol crossover reduction presents both temporary and permanent contributions: the latter could be related to membrane degradation. Moreover the effect of both methanol crossover and electric power reduction on fuel cell efficiency are discussed.

Vacuum-ultraviolet (VUV) photoionization of small methanol and methanol-water clusters  

SciTech Connect (OSTI)

In this work we report on thevacuum-ultraviolet (VUV) photoionization of small methanol and methanol-water clusters. Clusters of methanol with water are generated via co-expansion of the gas phase constituents in a continuous supersonic jet expansion of methanol and water seeded in Ar. The resulting clusters are investigated by single photon ionization with tunable vacuumultraviolet synchrotron radiation and mass analyzed using reflectron mass spectrometry. Protonated methanol clusters of the form (CH3OH)nH + (n=1-12) dominate the mass spectrum below the ionization energy of the methanol monomer. With an increase in water concentration, small amounts of mixed clusters of the form (CH3OH)n(H2O)H + (n=2-11) are detected. The only unprotonated species observed in this work are the methanol monomer and dimer. Appearance energies are obtained from the photoionization efficiency (PIE) curves for CH3OH +, (CH 3OH)2 +, (CH3OH)nH + (n=1-9), and (CH 3OH)n(H2O)H + (n=2-9 ) as a function of photon energy. With an increase in the water content in the molecular beam, there is an enhancement of photoionization intensity for methanol dimer and protonated methanol monomer at threshold. These results are compared and contrasted to previous experimental observations.

Methanol's transformation to commodity status stretches supply  

SciTech Connect (OSTI)

Methanol is undergoing a renaissance. Beginning in the US in the fourth quarter of 1993, methanol has seen a transformation from a low-growth, low-priced, overly abundant commodity chemical into a high-demand, undersupplied, cost-price driven product. As the economic recovery has spread to the rest of the world, methanol demand has dramatically increased. this meteoric rise has been further sparked in the US by increased use of methanol as an ingredient in gasoline oxygenates required by the federal government. Increased demand has led to the consolidation of producers, a scramble to reopen existing capacity, addition of capacity via product conversion, and plans for various future capacity expansions. Methanol fits alongside the other long-standing, major organic commodity chemicals-ethylbenzene, ethylene, ethylene dichloride, formaldehyde, propylene, styrene, terephthalic acid, and vinyl chloride. Methanol also serves both as a building block for many other chemicals--formaldehyde, acetic acid, and terephthalic acid--and as a solvent for many industrial uses.

Basic metal oxides as cocatalysts for Cu/SiO{sub 2} catalysts in the conversion of synthesis gas to methanol  

SciTech Connect (OSTI)

The catalytic behavior of Cu catalysts supported on ultrapure silica and promoted with Ca, Zn, and La oxides was investigated in the hydrogenation of CO and CO{sub 2} to methanol at high pressure. Cu on very pure silica produces hardly any methanol, while the addition of basic oxides and the use of {gamma}-alumina as support improve the catalyst performance. The strong promoting effect of Ca and La oxide on the silica-supported Cu and the weak promoting effect for alumina-supported Cu suggest that the basic oxide additives must be close to or in contact with the Cu particles to be effective in methanol synthesis. The methanol activity of Zn/Cu/SiO{sub 2} increased with increasing CO{sub 2} content in a CO-CO{sub 2}-H{sub 2} mixture, suggesting that CO{sub 2} is the main carbon source for methanol.

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

SciTech Connect (OSTI)

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

Science Journals Connector (OSTI)

Recent developments aiming at the accelerated commercialization of fuel cells for automotive applications have triggered an intensive research on fuel storage concepts for fuel cell cars. The fuel cell technology currently lacks technically and economically viable hydrogen storage technologies. On-board reforming of gasoline or methanol into hydrogen can only be regarded as an intermediate solution due to the inherently poor energy efficiency of such processes. Hydrogen storage in carbon nanofibers may lead to an efficient solution to the above described problems.

Opportunities for coal to methanol conversion  

SciTech Connect (OSTI)

The accumulations of mining residues in the anthracite coal regions of Pennsylvania offer a unique opportunity to convert the coal content into methanol that could be utilized in that area as an alternative to gasoline or to extend the supplies through blending. Additional demand may develop through the requirements of public utility gas turbines located in that region. The cost to run this refuse through coal preparation plants may result in a clean coal at about $17.00 per ton. After gasification and synthesis in a 5000 ton per day facility, a cost of methanol of approximately $3.84 per million Btu is obtained using utility financing. If the coal is to be brought in by truck or rail from a distance of approximately 60 miles, the cost of methanol would range between $4.64 and $5.50 per million Btu depending upon the mode of transportation. The distribution costs to move the methanol from the synthesis plant to the pump could add, at a minimum, $2.36 per million Btu to the cost. In total, the delivered cost at the pump for methanol produced from coal mining wastes could range between $6.20 and $7.86 per million Btu.

PtAu nanoparticles supported on carbon aerogel, namely 2:1 has been synthesized by the microwave-assisted polyol process. The structure of PtAu nanoparticles is characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The electrochemical property of PtAu catalysts for methanol oxidation is evaluated by cyclic voltammetry (CV). The results show that Au-modified Pt catalysts exhibit a high methanol tolerance and improved electrochemical catalytic activity, suggesting that carbon aerogel supported PtAu catalysts are better catalysts for the electrochemical oxidation of methanol than conventional Pt catalysts.

Hydrogen & Fuel Cells - Hydrogen - Hydrogen Quality  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Hydrogen Quality Issues for Fuel Cell Vehicles Hydrogen Quality Issues for Fuel Cell Vehicles Introduction Developing and implementing fuel quality specifications for hydrogen are prerequisites to the widespread deployment of hydrogen-fueled fuel cell vehicles. Several organizations are addressing this fuel quality issue, including the International Standards Organization (ISO), the Society of Automotive Engineers (SAE), the California Fuel Cell Partnership (CaFCP), and the New Energy and Industrial Technology Development Organization (NEDO)/Japan Automobile Research Institute (JARI). All of their activities, however, have focused on the deleterious effects of specific contaminants on the automotive fuel cell or on-board hydrogen storage systems. While it is possible for the energy industry to provide extremely pure hydrogen, such hydrogen could entail excessive costs. The objective of our task is to develop a process whereby the hydrogen quality requirements may be determined based on life-cycle costs of the complete hydrogen fuel cell vehicle "system." To accomplish this objective, the influence of different contaminants and their concentrations in fuel hydrogen on the life-cycle costs of hydrogen production, purification, use in fuel cells, and hydrogen analysis and quality verification are being assessed.

Theoretical model for methanol formation from CO and H/sub 2/ on zinc oxide surfaces  

SciTech Connect (OSTI)

Models are developed for the polar (0001) and nonpolar (1010) surfaces of ZnO in order to consider methanol formation from adsorbed carbon monoxide and hydrogen atoms. The heats of adsorption of H/sub x/CO and OH/sub x/CO (x = 0-3) species involved in methanol formation are computed to determine the enthalpy changes of reaction. Reaction sequences involving formyl or formate intermediates are considered. The reaction mechanism is catalyzed by the Cu/sup +/ to proceed through a methoxy intermediate on Cu/sup +//ZnO with a lower of the energy pathway. The ZnO surfaces are poor donors and function primarily as acceptors of electron density from CO. The donor role of Cu/sup +/ is demonstrated on the polar surface by increasing the heat of adsorption of acceptor adspecies and decreasing the heat of adsorption of donor adspecies. 22 references, 8 figures, 4 tables.

Supercritical methanol for polyethylene terephthalate depolymerization: Observation using simulator  

SciTech Connect (OSTI)

To apply PET depolymerization in supercritical methanol to commercial recycling, the benefits of supercritical methanol usage in PET depolymerization was investigated from the viewpoint of the reaction rate and energy demands. PET was depolymerized in a batch reactor at 573 K in supercritical methanol under 14.7 MPa and in vapor methanol under 0.98 MPa in our previous work. The main products of both reactions were the PET monomers of dimethyl terephthalate (DMT) and ethylene glycol (EG). The rate of PET depolymerization in supercritical methanol was faster than that of PET depolymerization in vapor methanol. This indicates supercritical fluid is beneficial in reducing reaction time without the use of a catalyst. We depicted the simple process flow of PET depolymerization in supercritical methanol and in vapor methanol, and by simulation evaluated the total heat demand of each process. In this simulation, bis-hydroxyethyl terephthalate (BHET) was used as a model component of PET. The total heat demand of PET depolymerization in supercritical methanol was 2.35 x 10{sup 6} kJ/kmol Produced-DMT. That of PET depolymerization in vapor methanol was 2.84 x 10{sup 6} kJ/kmol Produced-DMT. The smaller total heat demand of PET depolymerization in supercritical methanol clearly reveals the advantage of using supercritical fluid in terms of energy savings.

The hydrogen economy: Its history  

Science Journals Connector (OSTI)

The concept leading to a hydrogen economy lay in the work of a Nazi engineer, Lawaceck, 1968. I heard his suggestion of cheaper transfer of energy in hydrogen through pipes at a dinner in that year. A paper was published with Appleby in 1972 which was the first published document concerning that title and involving the title of A Hydrogen Economy. The first meeting was in Cornell University in 1973. In 1974 T. Nejat Veziroglu organized the first big meeting on hydrogen (900 attendees). At this meeting I presented privately to Veziroglu the possibilities of a world development and he told me that he was ready to put his organizing ability to use in spreading the ideas worldwide. However, he not only proceeded to do this but he, also a professor at the University of Miami, contributed several papers of notes, particularly the one with Awad of 1974 about the cost of pollution. Gregory worked at the Gas Research Institute from 1971 and confirmed the expectations put down by Lawaceck. Veziroglu founded the International Journal of Hydrogen Energy in 1974. Research in hydrogen was relatively low cost and therefore was taken up most eagerly by those from the newer countries. The National Science Foundation awarded Texas A&M University in 1982 a five year support for hydrogen as a fuel with the condition that half the costs be borne by at least five industrial companies. I was appointed director of the research under the grant and chose to concentrate upon the decomposition of water by solar light via an electrochemical photo fuel cell. We were able to obtain considerable increases in efficiency of decomposition of water by solar light, and at the time the work was interrupted we had 9.6 percent efficiency for decomposition. S.U.M. Khan and R. Kainthla were the principal contributors to the theory of using light via electrochemical cells for this purpose. The Texas A&M University work on hydrogen was interrupted in 1989 by the arrival of claims that one of my former students had carried out electrolysis of deuterium oxide saying that an extra unexplained heat had been observed and he suggested this heat was nuclear in origin. Later, seeking to reduce the cost of hydrogen as a fuel I involved Sol Zaromb in discussions and we came across the idea that if one included a carbon dioxide molecule obtained by removing it from the atmosphere in the structure of methanolAT, no increase in global warming would occur from the use of methanol with that condition, (published in 2008). By this condition methanol took on the largest advantage of gaseous hydrogen: That it did not cause global warming. The estimated cost of the new (anti-global warming) fuel, methanolAT was less than $30/GJ. This estimated cost could be compared with the $48/GJ which is now being supported by a French Canadian group who published an attractive book with six pages of calculations of costs. The difference between the cost estimated by this group and the costs which have been assumed by hydrogen enthusiasts in earlier times was that they took into account the auxiliary expenses which would come with the use of hydrogen, in particular the storage at high pressure. The characteristics of the new methanol to cause no global warming put that aspect of it on an equal footing to the gaseous hydrogen. The CO2 which was an essential part of the structure of methanolAT was necessary to be created in a stream, rather than directly from the atmosphere, but it was easily shown that this could be done by the use of biomass and by carbonaceous wastes. A German team under Weiderman and Grob appeared in 2008 and proceeded to suggest some extensions of the ideas which had been undergoing publication for some time. The aim of the German work was to reduce costs of a compound which they called Methasyn. The present situation is that the claim of methanolAT as a world fuel to be used without any concerns of exhaustion or pollution depends on the commercial point of view of the costs being less than that of obtaining oil from the tar sands.

Mechanism of methanol synthesis on Cu(100) and Zn/Cu(100) surfaces: Comparative dipped adcluster model study  

SciTech Connect (OSTI)

The mechanism of methanol synthesis from CO{sub 2} and H{sub 2} on Cu(100) and Zn/Cu(100) surfaces was studied using the dipped adcluster model (DAM) combined with ab initio Hartree-Fock (HF) and second-order Moeller-Plesset (MP2) calculations. On clean Cu(100) surface, calculations show that five successive hydrogenations are involved in the hydrogenation of adsorbed CO{sub 2} to methanol, and the intermediates are formate, dioxomethylene, formaldehyde, and methoxy. The rate-limiting step is the hydrogenation of formate to formaldehyde, and the Cu-Cu site is responsible for the reaction on Cu(100). The roles of Zn on Zn/Cu(100) catalyst are to modify the rate-limiting step of the reaction: to lower the activation energies of this step and to stabilize the dioxomethylene intermediate at the Cu-Zn site. The present comparative results indicate that the Cu-Zn site is the active site, which cooperates with the Cu-Cu site to catalyze methanol synthesis on a Cu-based catalyst. Electron transfer from surface to adsorbates is the most important factor in affecting the reactivity of these surface catalysts.

Hydrogenation apparatus  

DOE Patents [OSTI]

Hydrogenation reaction apparatus is described comprising a housing having walls which define a reaction zone and conduits for introducing streams of hydrogen and oxygen into the reaction zone, the oxygen being introduced into a central portion of the hydrogen stream to maintain a boundary layer of hydrogen along the walls of the reaction zone. A portion of the hydrogen and all of the oxygen react to produce a heated gas stream having a temperature within the range of from 1,100 to 1,900 C, while the boundary layer of hydrogen maintains the wall temperature at a substantially lower temperature. The heated gas stream is introduced into a hydrogenation reaction zone and provides the source of heat and hydrogen for a hydrogenation reaction. There also is provided means for quenching the products of the hydrogenation reaction. The present invention is particularly suitable for the hydrogenation of low-value solid carbonaceous materials to provide high yields of more valuable liquid and gaseous products. 2 figs.

Coking of zeolites during methanol conversion: Basic reactions of the MTO-, MTP- and MTG processes  

Science Journals Connector (OSTI)

Deactivation of acidic zeolite catalysts during methanol conversion is investigated for elucidating how spatial constraints interfere mechanistically. Detailed product composition including retained organic matter is determined in a time resolved mode. At 270300C with H-ZSM-5, first unsaturated hydrocarbons are formedmethane being the indicative co-product. Then the reaction rate increases auto-catalytically, but soon declines because of exhaustive pore filling. The retained organic matter consists mainly of ethyl-trimethyl-benzene- and isopropyl-dimethyl-benzene molecules. Alkylation of benzene rings with ethene and propene produces the deactivating molecules. At 475C, alkylation of benzene rings with olefins has shifted to the reverse, reactivating the H-ZSM-5 catalyst. Coke forms slowly on the surface of H-ZSM-5 crystallites. Spatial constraints suppress the formation of 2-ring aromatics. With the wide pore zeolite H-Y, fast deactivation is noticedbigger aromatic molecules can be formed and are retained. Methanol reactions on the protonic catalyst sites are visualized as CH3+ attack for methylation and dehydrogenation, methane being the hydrogen-rich co-product. Methanol conversion on zeolites H-ZSM-58, H-EU-1 and H-Beta is comparatively investigated. Zone ageing is discussed for favorable reactor design. It is shown, how a multi-compound product composition is the source of information for elucidating complex reaction mechanisms.

Coal to methanol to gasoline by the hydrocarb process  

SciTech Connect (OSTI)

The HYDROCARB Process converts coal or any other carbonaceous material to a clean carbon fuel and co-product gas or liquid fuel. By directing the co-product to liquid methanol, it becomes possible to produce methanol at costs as low as $0.13 to $0.14/gal as shown in Table 1 for a Western Lignite and Table 2 for an Eastern Bituminous coal. In the case of Western lignite, it is assumed that the carbon black fuel product can be sold at $3.00/MMBtu ($18/Bbl FOE) and for the Eastern coal at $2.50/MMBtu ($15/Bbl FOE). A methanol market is expected to develop due to the need for an automotive fuel with reduced pollutant emissions. However, should the methanol market not materialize as expected, then methanol can be readily converted to conventional gasoline by the addition of an MTG, methanol to gasoline process step. 1 fig., 3 tabs.

Liquefaction of natural gas to methanol for shipping and storage  

SciTech Connect (OSTI)

The penetration of natural gas into distant markets can be substantially increased by a new methanol synthesis process under development at the Brookhaven National Laboratory. The new methanol process is made possible by the discovery of a catalyst that drops synthesis temperatures from about 275/sup 0/C to about 100/sup 0/C. The new low temperature liquid catalyst can convert synthesis gas completely to methanol in a single pass through the methanol synthesis reactor. This characteristic leads to a further major improvement in the methanol plant. As a result of process design factors made possible by the BNL catalyst, the plant required to convert natural gas to methanol is very simple. Conversion of natural gas to methanol requires two chemical reactions, both of which are exothermic, and thus represent a loss of heating value in the feed natural gas. This loss is about 20% of the feed gas energy, and is, therefore, higher than the 10% loss in energy in natural gas liquefaction, which is a simpler physical - not a chemical - change. The energy disadvantage of the methanol option must be balanced against the advantage of a much lower capital investment requirement made possible by the new BNL synthesis. Preliminary estimates show that methanol conversion and shipping require an investment for liquefaction to methanol, and shipping liquefied methanol that can range from 35 to 50% of the capital needed for the LNG plant and LNG tanker fleet. This large reduction in capital requirements is expected to make liquefaction to methanol attractive in many cases where the LNG capital needs are prohibitive. 3 tabs.

Chapter 4 - Hydrogen and Fuel Cell Systems  

Science Journals Connector (OSTI)

Abstract In this chapter, hydrogen and fuel cell systems are introduced. Hydrogen is closely related to fuel cells because fuel cells are very efficient devices for power generation which when supplied with hydrogen generate non-polluting effluents, mainly water or steam. A hydrogen economy is necessary in the context of continuous growth of population and per-capita energy consumption. In this context, renewable energy solutionsespecially solarbecome more important and their harvesting requires hydrogen as energy carrier. Therefore the role of hydrogen and fuel cell systems in power generation becomes very important. As detailed in the chapter, these systems are useful for converting the fluctuating and intermittent energy of renewable sources and providing power on demand. Hydrogen and fuel cell systems can work either as grid-connected or as independent power generators. Connection to the grid allows for better load leveling and major savings as well as for reduction of pollution associated with power generation. Hydrogen can also be used to power residences and to cogenerate heat or other commodities. In addition, hydrogen and fuel cell technologies are much required for the transportation sector, where they can contribute to pollution and cost reduction and increased efficiency. Hydrogen production methods are reviewed in this chapter with a focus on electrolysis and thermochemical cycles. These systems appear to be leading technologies for the future. Other revised hydrogen production methods are gasification and reforming, which are very relevant for biomass conversion into hydrogen. Photochemical and photo-biochemical hydrogen production methods are also discussed. All types of fuel cells are introduced; these include alkaline, proton-exchange-membrane, phosphoric acid, molten carbonate, solid oxide, direct methanol, and direct ammonia fuel cells. Construction and specific application for power generation are presented for each type. The modeling and optimization aspects of fuel cells and their systems are explained. Several power generation systems with fuel cells are discussed, in which each type of fuel cells has specific system requirements. The overall system must include various types of separators, pumps, and compressors depending on the case. In aqueous systems water must be recycled, e.g., in the case of proton-exchange membrane fuel cells water must be actually fed in excess so that the membrane is wetted. Also for a direct methanol fuel cell water must be recovered and recycled. In molten carbonate fuel cell systems carbon dioxide must be recovered and recycled. In solid oxide fuel cell systems, the fuel must be supplied in excess and is not completely consumed; therefore it is important to couple these systems with gas turbines.

Conversion of methanol to gasoline commercial plant study. Coal to gasoline via methanol  

SciTech Connect (OSTI)

Under the joint sponsorship of the German Federal Minister of Research and Technology (BMFT) and the US Department of Energy (DOE), a research program was initiated concerning the ''Conversion of Methanol to Gasoline (MTG), Engineering, Construction and Operation of a Demonstration Plant''. The purpose of the 100 BPD demonstration plant was to demonstrate the feasibility of and to obtain data required for scale-up of the fluid-bed MTG process to a commercial size plant. As per requirements of Annex 3 of the Governmental Agreement, this study, in addition to the MTG plant, also includes the facilities for the production of methanol. The feedstock basis for the production of methanol shall be coal. Hence this study deals with the production of gasoline from coal (CTG-Coal to Gasoline). The basic objective of this study is to assess the technical feasibility of the conversion of methanol to gasoline in a fluid-bed system and to evaluate the process economies i.e., to evlauate the price of the product in relation to the price of the feedstock and plant capacity. In connection with technical feasibility, the scale up criteria were developed from the results obtained and experience gathered over an operational period of 8600 hours of the ''100 BPD Demonstration Plant''. The scale up philosophy is detailed in chapter 4. The conditions selected for the design of the MTG unit are detailed in chapter 5. The scope of the study covers the production of gasoline from coal, in which MTG section is dealt with in detail (refer to chapter 5). Information on other plant sections in this study are limited to that sufficient to: generate overall mass balance; generate rate of by-products and effluents; incorporate heat integration; generate consumption figures; and establish plant investment cost.

Hydrogen & Fuel Cells - Hydrogen - Hydrogen Storage  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Hydrogen Storage Systems Modeling and Analysis Hydrogen Storage Systems Modeling and Analysis Several different approaches are being pursued to develop on-board hydrogen storage systems for light-duty vehicle applications. The different approaches have different characteristics, such as: the thermal energy and temperature of charge and discharge kinetics of the physical and chemical process steps involved requirements for the materials and energy interfaces between the storage system and the fuel supply system on one hand, and the fuel user on the other Other storage system design and operating parameters influence the projected system costs as well. Argonne researchers are developing thermodynamic, kinetic, and engineering models of the various hydrogen storage systems to understand the characteristics of storage systems based on these approaches and to evaluate their potential to meet the DOE targets for on-board applications. The DOE targets for 2015 include a system gravimetric capacity of 1.8 kWh/kg (5.5 wt%) and a system volumetric capacity of 1.3 kWh/L (40 g/L). We then use these models to identify significant component and performance issues, and evaluate alternative system configurations and design and operating parameters.

Methanol synthesis using a catalyst combination of alkali or alkaline earth salts and reduced copper chromite for methanol synthesis  

DOE Patents [OSTI]

The present invention relates to a novel route for the synthesis of methanol, and more specifically to the production of methanol by contacting synthesis gas under relatively mild conditions in a slurry phase with a catalyst combination comprising reduced copper chromite and basic alkali salts or alkaline earth salts. The present invention allows the synthesis of methanol to occur in the temperature range of approximately 100.degree.-160.degree. C. and the pressure range of 40-65 atm. The process produces methanol with up to 90% syngas conversion per pass and up to 95% methanol selectivity. The only major by-product is a small amount of easily separated methyl formate. Very small amounts of water, carbon dioxide and dimethyl ether are also produced. The present catalyst combination also is capable of tolerating fluctuations in the H.sub.2 /CO ratio without major deleterious effect on the reaction rate. Furthermore, carbon dioxide and water are also tolerated without substantial catalyst deactivation.

Methanol production from Eucalyptus wood chips. Working Document 9. Economics of producing methanol from Eucalyptus in Central Florida  

SciTech Connect (OSTI)

A detailed feasibility study of producing methanol from Eucalyptus in Central Florida encompasses all phases of production - from seedling to delivery of finished methanol. The project includes the following components: (1) production of 55 million, high quality, Eucalyptus seedlings through tissue culture; (2) establishment of a Eucalyptus energy plantation on approximately 70,000 acres; and (3) engineering for a 100 million gallon-per-year methanol production facility. In addition, the potential environmental impacts of the whole project were examined, safety and health aspects of producing and using methanol were analyzed, and site specific cost estimates were made. The economics of the project are presented here. Each of the three major components of the project - tissue culture lab, energy plantation, and methanol refinery - are examined individually. In each case a site specific analysis of the potential return on investment was conducted.

Research on methanol-burning, two-stroke engines  

SciTech Connect (OSTI)

In looking for the possibility of burning methanol in the two-stroke marine diesel engine, Mitsubishi decided that its investigations would be for a pure methanol-burning engine. Since ignition of methanol by the straight forward diesel cycle is not attainable, Mitsubishi decided to use glow plugs for ignition. The result has been the adaptation of the 450 mm bore test engine, at Nagasaki, with a special cylinder head carrying two methanol precombustion chambers and two main methanol injectors. Results from the tests at Nagasaki showed that NO[sub x] formation was no more than 500 ppm at full load, while thermal efficiency was at least equal to that of a straight diesel engine. A base model ship for Japanese coastal waters operation is being studied. Plans of the ship have been sent to the Japanese classification society, NK, and they include a separate methanol treatment room and storage tanks. The committee concluded that a methanol-engined ship of about 1000 dwt can be operated economically with a relatively small increase in freight rate. Lower crew costs are part of that equation, because of an expected decrease in machinery maintenance. Conceptual approval for the project is now being sought with NK. 2 figs.

Methanol adsorption in zeolites - A first-priniciples study  

SciTech Connect (OSTI)

The methanol to gasoline (MTG) conversion process, using a zeolite catalyst, is of major commercial importance. However, the first step of the reaction, involving methanol adsorption on the zeolite catalyst, is still not well understood. This paper describes first-principles calculations performed on periodic zeolite models to investigate the nature of methanol adsorption. We have examined a number of possible geometries for this adsorption and found that the nature of the adsorbed species can depend on the particular zeolites structure. In more open ring structures, as found in chabazite, the stable form of methanol is found to be protonated, in contrast to results of previous calculations on cluster models. However, in the sodalite structure methanol is found to be simply physisorbed. The vibrational spectra of the adsorbed species have been studied and compared to experimental results. It is found that both chemisorbed methanol and physisorbed methanol give strongly red-shifted O-H stretching frequencies, but the former can be distinguished by the H-O-H bending mode. 50 refs., 13 figs., 3 tabs.

Hydrogen as a fuel for fuel cell vehicles: A technical and economic comparison  

SciTech Connect (OSTI)

All fuel cells currently being developed for near term use in vehicles require hydrogen as a fuel. Hydrogen can be stored directly or produced onboard the vehicle by reforming methanol, ethanol or hydrocarbon fuels derived from crude oil (e.g., Diesel, gasoline or middle distillates). The vehicle design is simpler with direct hydrogen storage, but requires developing a more complex refueling infrastructure. In this paper, the authors compare three leading options for fuel storage onboard fuel cell vehicles: compressed gas hydrogen storage; onboard steam reforming of methanol; onboard partial oxidation (POX) of hydrocarbon fuels derived from crude oil. Equilibrium, kinetic and heat integrated system (ASPEN) models have been developed to estimate the performance of onboard steam reforming and POX fuel processors. These results have been incorporated into a fuel cell vehicle model, allowing us to compare the vehicle performance, fuel economy, weight, and cost for various fuel storage choices and driving cycles. A range of technical and economic parameters were considered. The infrastructure requirements are also compared for gaseous hydrogen, methanol and hydrocarbon fuels from crude oil, including the added costs of fuel production, storage, distribution and refueling stations. Considering both vehicle and infrastructure issues, the authors compare hydrogen to other fuel cell vehicle fuels. Technical and economic goals for fuel cell vehicle and hydrogen technologies are discussed. Potential roles for hydrogen in the commercialization of fuel cell vehicles are sketched.

Active Hydrogen  

Science Journals Connector (OSTI)

Dry hydrogen can be activated in an electric discharge if the pressure and voltage are carefully regulated. Active hydrogen reduces metallic sulphides whose heat of formation is 22 000 cal. or less. The active gas is decomposed by 3 cm of well packed glass wool. A quantitative method is given for the determination of active hydrogen. Less of the active gas is formed in a tube coated with stearic acid or phosphoric acid than when no coating is employed. The decay reaction was found to follow the expression for a unimolecular reaction. The rate of decay appears to be independent of the wall surface. The period of half?life at room temperature and 40 mm pressure is 0.2 sec. approximately. The energy of formation of active hydrogen is approximately 18 000 cal. The energy of activation for the decay of the active constituent is approximately 17 800 cal. The properties of active hydrogen are considered in relation to the properties predicted for H3.

Evaluation of platinum-based catalysts for methanol electro-oxidation in phosphoric acid electrolyte  

SciTech Connect (OSTI)

Carbon-supported catalysts of Pt, Pt/Ru, Pt/Ru/W, and Pt/Ru/Pd were evaluated for the electro-oxidation of methanol in phosphoric acid at 180 C. These catalysts were characterized using cyclic voltammetry and x-ray diffraction. Addition of Ru to a 0.5 mg/cm{sup 2} Pt catalyst (1:1 atomic ratio) caused a large reduction in polarization. The open-circuit voltage was reduced by 100 mV and polarization at 400 mA/cm{sup 2} was reduced by 180 mV. A Pt/Ru (5:2) catalyst with the same Pt content lowered the open-circuit voltage 70 mV. Additions of W to form Pt/Ru/W (1:1:1, atomic ratio) and Pd to form Pt/Ru/Pd (2:2:1), all with the same platinum loading, gave the same performance as Pt/Ru (1:1) without the additions. All of the catalysts showed two Tafel slopes, 140 mV/dec at lower polarizations and 100 to 120 mV/dec at higher polarizations, indicating that the reaction mechanisms are the same for all of the catalysts. Methanol oxidation is greatly enhanced at 180 C in phosphoric acid compared to the lower operating temperatures of a perfluorosulfonic acid electrolyte. The exchange current density for methanol oxidation is higher than that for O{sub 2} reduction. Ru metal dissolves from catalysts at high potentials. Hydrogen oxidation in the presence of 1 mole percent carbon monoxide showed carbon monoxide tolerance in the order: Pt/Ru/Pd > Pt/Ru > Pt.

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

First principles Tafel kinetics of methanol oxidation on Pt(111)  

Science Journals Connector (OSTI)

Abstract Electrocatalytic methanol oxidation is of fundamental importance in electrochemistry and also a key reaction in direct methanol fuel cell. To resolve the kinetics at the atomic level, this work investigates the potential-dependent reaction kinetics of methanol oxidation on Pt(111) using the first principles periodic continuum solvation model based on modified-PoissonBoltzmann equation (CM-MPB), focusing on the initial dehydrogenation elementary steps. A theoretical model to predict Tafel kinetics (current vs potential) is established by considering that the rate-determining step of methanol oxidation (to CO) is the first CH bond breaking (CH3OH(aq)?CH2OH*+H*) according to the computed free energy profile. The first CH bond breaking reaction needs to overcome a large entropy loss during methanol approaching to the surface and replacing the adsorbed water molecules. While no apparent charge transfer is involved in this elementary step, the charge transfer coefficient of the reaction is calculated to be 0.36, an unconventional value for charge transfer reactions, and the Tafel slope is deduced to be 166mV. The results show that the metal/adsorbate interaction and the solvation environment play important roles on influencing the Tafel kinetics. The knowledge learned from the potential-dependent kinetics of methanol oxidation can be applied in general for understanding the electrocatalytic reactions of organic molecules at the solidliquid interface.

Methanol fumigation of a light duty automotive diesel engine  

SciTech Connect (OSTI)

An Oldsmobile 5.7 l V-8 diesel engine was fumigated with methanol in amounts up to 40% of the fuel energy. The primary objectives of this study were to determine the effect of methanol fumigation on fuel efficiency, smoke, nitric oxide emission, and the occurrence of severe knock. An assessment of the biological activity for samples of the raw exhaust particulate and its soluable organic extract was also made using both the Ames Salmonella typhimurium test and the Bacillus subtilis Comptest. Results are presented for a test matrix consisting of twelve steady state operating conditions chosen to reflect over-the-road operation of a diesel engine powered automobile. Generally methanol fumigation was found to decrease NO emission for all conditions, to have a slight effect on smoke opacity, and to have a beneficial effect on fuel efficiency at higher loads. Also at higher loads the methanol was found to induce what was defined as knock limited operation. While the biological activity of the raw particulate was generally found to be lower than that of the soluble organic fraction, the fumigation of methanol appears to enhance this activity in both cases.

Single-Step Syngas-to-Distillates (S2D) Synthesis via Methanol and Dimethyl Ether Intermediates: Final Report  

SciTech Connect (OSTI)

The objective of the work was to enhance price-competitive, synthesis gas (syngas)-based production of transportation fuels that are directly compatible with the existing vehicle fleet (i.e., vehicles fueled by gasoline, diesel, jet fuel, etc.). To accomplish this, modifications to the traditional methanol-to-gasoline (MTG) process were investigated. In this study, we investigated direct conversion of syngas to distillates using methanol and dimethyl ether intermediates. For this application, a Pd/ZnO/Al2O3 (PdZnAl) catalyst previously developed for methanol steam reforming was evaluated. The PdZnAl catalyst was shown to be far superior to a conventional copper-based methanol catalyst when operated at relatively high temperatures (i.e., >300C), which is necessary for MTG-type applications. Catalytic performance was evaluated through parametric studies. Process conditions such as temperature, pressure, gas-hour-space velocity, and syngas feed ratio (i.e., hydrogen:carbon monoxide) were investigated. PdZnAl catalyst formulation also was optimized to maximize conversion and selectivity to methanol and dimethyl ether while suppressing methane formation. Thus, a PdZn/Al2O3 catalyst optimized for methanol and dimethyl ether formation was developed through combined catalytic material and process parameter exploration. However, even after compositional optimization, a significant amount of undesirable carbon dioxide was produced (formed via the water-gas-shift reaction), and some degree of methane formation could not be completely avoided. Pd/ZnO/Al2O3 used in combination with ZSM-5 was investigated for direct syngas-to-distillates conversion. High conversion was achieved as thermodynamic constraints are alleviated when methanol and dimethyl are intermediates for hydrocarbon formation. When methanol and/or dimethyl ether are products formed separately, equilibrium restrictions occur. Thermodynamic relaxation also enables the use of lower operating pressures than what would be allowed for methanol synthesis alone. Aromatic-rich hydrocarbon liquid (C5+), containing a significant amount of methylated benzenes, was produced under these conditions. However, selectivity control to liquid hydrocarbons was difficult to achieve. Carbon dioxide and methane formation was problematic. Furthermore, saturation of the olefinic intermediates formed in the zeolite, and necessary for gasoline production, occurred over PdZnAl. Thus, yield to desirable hydrocarbon liquid product was limited. Evaluation of other oxygenate-producing catalysts could possibly lead to future advances. Potential exists with discovery of other types of catalysts that suppress carbon dioxide and light hydrocarbon formation. Comparative techno-economics for a single-step syngas-to-distillates process and a more conventional MTG-type process were investigated. Results suggest operating and capital cost savings could only modestly be achieved, given future improvements to catalyst performance. Sensitivity analysis indicated that increased single-pass yield to hydrocarbon liquid is a primary need for this process to achieve cost competiveness.

Methanol injection and recovery in a large turboexpander plant. [Canada  

SciTech Connect (OSTI)

Methanol is used to prevent hydrate formation in Petro-Canada's 2000 MMSCFD Empress expander plant. Injection and recovery facilities have operated essentially trouble-free since start-up late in 1979. A portion of the methanol recovery section has been modified to provide removal of the H/sub 2/S and most of the COS from the propane product stream, concurrent with methanol recovery. The Empress straddle plant strips natural gas liquids from pipeline gas leaving Alberta for eastern Canadian and U.S. markets. The original cold oil absorption plant, started up in 1964 and expanded in 1967, recovered over 90% of the propane and virtually all of the heavier components. In 1976, a market for ethane was secured as feedstock for the world-scale ethylene complex under construction in Alberta, and it was decided to replace the cold oil plant with a turboexpander facility. The plant and its operations are described in some detail. 2 refs.

SciTech Connect (OSTI)

This investigation explores direct methanol fuel cells incorporating perovskite anode electrocatalysts. Preliminary electrochemical performance was addressed following incorporation of electrocatalysts into polymer electrolyte (Nafion 417) fuel cells. Perovskite electrocatalysts demonstrating activity towards direct methanol oxidation during cyclic voltammetry measurements included, respectively, SrRu[sub 0.5]Pt[sub 0.5]O[sub 3], SrRu[sub 0.5]Pd[sub 0.5]O[sub 3], SrPdO[sub 3], SmCoO[sub 3], SrRuO[sub 3], La[sub 0.8]Ce[sub 0.2]CoC[sub 3],SrCo[sub 0.5]Ti[sub 0.5]O[sub 3], and La[sub 0.8]Sr[sub 0.2]CoO[sub 3] where SrRu[sub 0.5]Pt[sub 0.5]P[sub 3] gave methanol oxidation currents up to 28 mA/cm[sup 2] at 0.45 V vs. SCE. Correlations were found between electrocatalyst solid-state and thermodynamic parameters corresponding to, respectively, molecular electronic polarizability, the optical dielectric constant, the perovskite spin-only magnetic moment, the number of d-electrons in perovskite A and B lattice sites, and the average metal-oxygen binding energy for the perovskite lattice, and corresponding fuel cell performance. This may have future merit for the prediction of new electrocatalyst family members for promoting direct methanol oxidation. Methanol diffusion from anode to cathode compartments appears to be a major obstacle to the development of polymer electrolyte methanol fuel cells.

A new blending agent and its effects on methanol-gasoline fuels  

SciTech Connect (OSTI)

The major difficulty encountered with the use of methanol-gasoline blends as SI engine fuel is their tendency to phase separation due to the hydrophilic properties of methanol. Phase separation can lead to some utilization problems. Using a blending agent for the methanol-gasoline system is the common approach taken towards solving the phase separation problem. In this study introduces fraction of molasses fuel oil as an effective new blending agent for methanol-gasoline fuel.

CFD analysis of the effects of the flow distribution and heat losses on the steam reforming of methanol in catalytic (Pd/ZnO) microreactors  

Science Journals Connector (OSTI)

Abstract A three-dimensional computational fluid dynamics (CFD) simulation study of the effects of the flow distribution and the heat losses on the performance of microchannels and microslits reactors for the steam reforming of methanol (SRM) over Pd/ZnO is presented. Several flow distributing headers covering a wide range of the flow diffuser expansion angle (?) have been considered. Large values of ? lead to flow maldistribution characterized by jet flow resulting in negative effects on the SRM conversion and hydrogen yield, especially for the microslits at high reaction temperatures and space velocities. Simulations have also evidenced that heat losses constitute a critical issue for microreactors operation, particularly at low space velocities. Heat losses may reach very high values, above 8090% of the energy supplied to the microreactor, with the consequence that it may be necessary to provide up to 9times the heat of the SRM reaction to achieve high methanol conversions.

Hydrogen Permeation Barrier Coatings  

SciTech Connect (OSTI)

Gaseous hydrogen, H2, has many physical properties that allow it to move rapidly into and through materials, which causes problems in keeping hydrogen from materials that are sensitive to hydrogen-induced degradation. Hydrogen molecules are the smallest diatomic molecules, with a molecular radius of about 37 x 10-12 m and the hydrogen atom is smaller still. Since it is small and light it is easily transported within materials by diffusion processes. The process of hydrogen entering and transporting through a materials is generally known as permeation and this section reviews the development of hydrogen permeation barriers and barrier coatings for the upcoming hydrogen economy.

Commercial-scale demonstration of the Liquid Phase Methanol (LPMEOH{trademark}) Process. Peroxide formation of dimethyl ether in methanol mixtures  

SciTech Connect (OSTI)

Organic peroxides could form when dimethyl ether in methanol is stored for three to six months at a time. The objective of this work was to determine the level of peroxide formation from dimethyl ether in reagent grade methanol and raw methanol at room temperature under 3 atmospheres (45 psig) of air. Raw methanol is methanol made from syngas by the LPMEOH Process without distillation. Aliphatic ethers tend to react slowly with oxygen from the air to form unstable peroxides. However, there are no reports on peroxide formation from dimethyl ether. After 172 days of testing, dimethyl ether in either reagent methanol or raw methanol at room temperature and under 60--70 psig pressure of air does not form detectable peroxides. Lack of detectable peroxides suggests that dimethyl ether or dimethyl ether and methanol may be stored at ambient conditions. Since the compositions of {approximately} 1.3 mol% or {approximately} 4.5 mol% dimethyl ether in methanol do not form peroxides, these compositions can be considered for diesel fuel or an atmospheric turbine fuel, respectively.

The glass matrix has pores large enough to allow gases having hydrogen to pass through the matrix, yet small enough to hold the particles dispersed within the matrix so that the hydrogen-absorbing particles are not released during repeated hydrogen absorption/desorption cycles.

Investigation of operating range in a methanol fumigated diesel engine  

Science Journals Connector (OSTI)

Abstract An experimental study was conducted to investigate the operating range and combustion characteristics in a methanol fumigated diesel engine. The test engine was a six-cylinder, turbocharged direct injection engine with methanol injected into the intake manifold of each cylinder. The experimental results showed that the viable diesel methanol dual fuel (DMDF) operating range in terms of load and methanol substitution percent (MSP) was achieved over a load range from 6% to 100%. The operating range was restricted by four bounds: partial burning, misfire, roar combustion and knock. The lower bound of the operating range was the partial burn bound, which occurred under very low load conditions with high MSP. As the load increased to medium load, MSP reached its maximum value of about 76%, and the onset of misfire provided the right bound for normal operation. At medium to high load, maximum MSP began to decrease. DMDF combustion with excessive MSP was extremely loud with high pressure rise rate, which defined the roar combustion bound. As it increased to nearly full load, measured pressure traces in-cylinder showed strong acoustic oscillations. The appearance of knock provided the upper bound of the operating range. In general, as the load increased, the characters of the combustion changed from partial burn to misfire to roar combustion and to knocking. The range between these four bounds and the neat diesel combustion bound constituted the viable operating range. Over the viable operating range, DMDF combustion worsened the brake thermal efficiency (BTE) at light load while boosted it at medium and high load.

New Catalysts for Direct Methanol Oxidation Fuel Cells  

SciTech Connect (OSTI)

A new class of efficient electrocatalytic materials based on platinum - metal oxide systems has been synthetized and characterized by several techniques. Best activity was found with NiWO{sub 4}-, CoWO{sub 4}-, and RuO{sub 2}- srpported platinum catalysts. A very similar activity at room temperature was observed with the electrodes prepared with the catalyst obtained from International Fuel Cells Inc. for the same Pt loading. Surprisingly, the two tungstates per se show a small activity for methanol oxidation without any Pt loading. Synthesis of NiWO{sub 4} and CoWO{sub 4} were carried out by solid-state reactions. FTIR spectroscopy shows that the tungstates contain a certain amount of physically adsorbed water even after heating samples at 200{degrees}C. A direct relationship between the activity for methanol oxidation and the amount of adsorbed water on those oxides has been found. The Ru(0001) single crystal shows a very small activity for CO adsorption and oxidation, in contrast to the behavior of polycrystalline Ru. In situ extended x-ray absorption fine structure spectroscopy (EXAFS) and x-ray absorption near edge spectroscopy (XANES) showed that the OH adsorption on Ru in the Pt-Ru alloy appears to be the limiting step in methanol oxidation. This does not occur for Pt-RuO{SUB 2} electrocatalyst, which explains its advantages over the Pt-Ru alloys. The IFCC electrocatalyst has the properties of the Pt-Ru alloy.

Recent advances in high-performance direct methanol fuel cells  

SciTech Connect (OSTI)

Direct methanol fuel cells for portable power applications have been advanced significantly under DARPA- and ARO-sponsored programs over the last five years. A liquid-feed direct methanol fuel cell developed under these programs, employs a proton exchange membrane as electrolyte and operates on aqueous solutions of methanol with air or oxygen as the oxidant. Power densities as high as 320 mW/cm{sup 2} have been demonstrated. Demonstration of five-cell stack based on the liquid-feed concept have been successfully performed by Giner Inc. and the Jet Propulsion Laboratory. Over 2000 hours of life-testing have been completed on these stacks. These fuel cells have been also been demonstrated by USC to operate on alternate fuels such as trimethoxymethane, dimethoxymethane and trioxane. Reduction in the parasitic loss of fuel across the fuel cell, a phenomenon termed as {open_quotes}fuel crossover{close_quotes} has been achieved using polymer membranes developed at USC. As a result efficiencies as high as 40% is considered attainable with this type of fuel cell. The state-of-development has reached a point where it is now been actively considered for stationary, portable and transportation applications. The research and development issues have been the subject of several previous articles and the present article is an attempt to summarize the key advances in this technology.

Methanol and methyl fuel catalysts. Final technical report, September 1978-August 1980  

SciTech Connect (OSTI)

The Cu/ZnO methanol synthesis catalysts were investigated for (1) the role of additives such as alumina, ceria, and lanthana, (2) the effect of carbon dioxide in the H/sub 2//CO synthesis gas, (3) the chemisorption of hydrogen and carbon monoxide on the catalysts, and (4) the chemical poisoning of the catalysts by sulfur- and chlorine-containing compounds. Maximum activity and selectivity were obtained with a binary catalyst having a composition of Cu/ZnO = 30/70 metal atomic percent and with a synthesis gas of H/sub 2//CO/CO/sub 2/ = 70/28/2 volume percent in the absence of strongly reducing or strongly oxidizing chemical poisons. Both the binary and the ternary catalysts were fully characterized by scanning transmission electron microscopy (STEM), X-ray diffraction, electron spectroscopy, diffuse reflectance spectroscopy, and surface area-pore distribution measurements. Structural and morphologic information is presented in this report in detail for very active Cu/ZnO/Al/sub 2/O/sub 3/ catalysts prepared from acetates and for other catalysts in which the third component caused a loss of activity.

The use of advanced steam reforming technology for hydrogen production  

SciTech Connect (OSTI)

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

Methanol as an alternative transportation fuel in the U.S.  

Alternative Fuels and Advanced Vehicles Data Center [Office of Energy Efficiency and Renewable Energy (EERE)]

Methanol as an alternative transportation fuel in the US: Methanol as an alternative transportation fuel in the US: Options for sustainable and/or energy-secure transportation L. Bromberg and W.K. Cheng Prepared by the Sloan Automotive Laboratory Massachusetts Institute of Technology Cambridge MA 02139 September 27, 2010 Finalized November 2, 2010 Revised November 28, 2010 Final report UT-Battelle Subcontract Number:4000096701 1 Abstract Methanol has been promoted as an alternative transportation fuel from time to time over the past forty years. In spite of significant efforts to realize the vision of methanol as a practical transportation fuel in the US, such as the California methanol fueling corridor of the 1990s, it did not succeed on a large scale. This white paper covers all important aspects of methanol as a transportation fuel.

Fluid-bed studies of olefin production from methanol  

SciTech Connect (OSTI)

With newly developed technology, conversion of methanol to hydrocarbons represents the final link in the production of premium transportation fuels from coal or natural gas. The methanol-to-gasoline (MTG) process has been developed. The more readily scaled fixed-bed version is the heart of the New Zealand Gas-to-gasoline complex, which will produce 14,000 BPD high octane gasoline from 120 million SCFD gas. The fluid-bed version of the process, which is also available for commercial license, has a higher thermal efficiency and possesses substantial yield and octane advantages over the fixed-bed. Successful scale-up was completed in 1984 in a 100 BPD semi-works plant near Cologne, West Germany. The project funded jointly by the U.S. and German governments and an industrial consortium comprised of Mobil; Union Rheinsche Braunkohlen Kraftstoff, AG; and Uhde, GmbH. The 100 BPD MTG project was extended recently to demonstrate a related fluid bed process for selective conversion of methanol to light olefins (MTO). The products of the MTO reaction make an excellent feed to the commercially available Mobile-Olefins-to-Gasoline-and-Distillate process (MOGD) which selectively converts olefins to premium transportation fuels . A schematic of the combined processes is shown. Total liquid fuels production is typically greater than 90 wt% of hydrocarbon in the feed. Distillate/gasoline product ratios from the plant can be adjusted over a wide range to meet seasonal demands. This paper describes the initial scale-up of the MTO process from a micro-fluid-bed reactor (1-10 grams of catalyst) to a large pilot unit (10-25 kilograms of catalyst).

Utilization of coal mine methane for methanol and SCP production. Topical report, May 5, 1995--March 4, 1996  

SciTech Connect (OSTI)

The feasibility of utilizing a biological process to reduce methane emissions from coal mines and to produce valuable single cell protein (SCP) and/or methanol as a product has been demonstrated. The quantities of coal mine methane from vent gas, gob wells, premining wells and abandoned mines have been determined in order to define the potential for utilizing mine gases as a resource. It is estimated that 300 MMCFD of methane is produced in the United States at a typical concentration of 0.2-0.6 percent in ventilation air. Of this total, almost 20 percent is produced from the four Jim Walter Resources (JWR) mines, which are located in very gassy coal seams. Worldwide vent gas production is estimated at 1 BCFD. Gob gas methane production in the U.S. is estimated to be 38 MMCFD. Very little gob gas is produced outside the U.S. In addition, it is estimated that abandoned mines may generate as much as 90 MMCFD of methane. In order to make a significant impact on coal mine methane emissions, technology which is able to utilize dilute vent gases as a resource must be developed. Purification of the methane from the vent gases would be very expensive and impractical. Therefore, the process application must be able to use a dilute methane stream. Biological conversion of this dilute methane (as well as the more concentrated gob gases) to produce single cell protein (SCP) and/or methanol has been demonstrated in the Bioengineering Resources, Inc. (BRI) laboratories. SCP is used as an animal feed supplement, which commands a high price, about $0.11 per pound.

Desorption Kinetics of Methanol, Ethanol, and Water from Graphene  

SciTech Connect (OSTI)

The desorption kinetics of methanol, ethanol, and water from graphene covered Pt(111) are investigated. The temperature programmed desorption (TPD) spectra for both methanol and ethanol have well-resolved first, second, third, and multilayer layer desorption peaks. The alignment of the leading edges is consistent with zero-order desorption kinetics from all layers. In contrast, for water the first and second layers are not resolved. At low water coverages (< 1 ML) the initial desorption leading edges are aligned but then fall out of alignment at higher temperatures. For thicker water layers (10 to 100 ML), the desorption leading edges are in alignment throughout the desorption of the film. The coverage dependence of the desorption behavoir suggests that at low water coverages the non-alignment of the desorption leading edges is due to water dewetting from the graphene substrate. Kinetic simulations reveal that the experimental results are consistent with zero-order desorption. The simulations also show that fractional order desorption kinetics would be readily apparent in the experimental TPD spectra.

U.S. Geographic Analysis of the Cost of Hydrogen from Electrolysis  

SciTech Connect (OSTI)

This report summarizes U.S. geographic analysis of the cost of hydrogen from electrolysis. Wind-based water electrolysis represents a viable path to renewably-produced hydrogen production. It might be used for hydrogen-based transportation fuels, energy storage to augment electricity grid services, or as a supplement for other industrial hydrogen uses. This analysis focuses on the levelized production, costs of producing green hydrogen, rather than market prices which would require more extensive knowledge of an hourly or daily hydrogen market. However, the costs of hydrogen presented here do include a small profit from an internal rate of return on the system. The cost of renewable wind-based hydrogen production is very sensitive to the cost of the wind electricity. Using differently priced grid electricity to supplement the system had only a small effect on the cost of hydrogen; because wind electricity was always used either directly or indirectly to fully generate the hydrogen. Wind classes 3-6 across the U.S. were examined and the costs of hydrogen ranged from $3.74kg to $5.86/kg. These costs do not quite meet the 2015 DOE targets for central or distributed hydrogen production ($3.10/kg and $3.70/kg, respectively), so more work is needed on reducing the cost of wind electricity and the electrolyzers. If the PTC and ITC are claimed, however, many of the sites will meet both targets. For a subset of distributed refueling stations where there is also inexpensive, open space nearby this could be an alternative to central hydrogen production and distribution.

4.12 - Hydrogen and Fuel Cells in Transport  

Science Journals Connector (OSTI)

Abstract This chapter reviews the several applications of hydrogen and fuel cells in transport. Early fuel cell markets have tested hydrogen for auxiliary power applications, but other fuels such as methanol, natural gas, and propane have been preferred because they are more available. Until now, the best successes have been forklifts where battery propulsion can be inflexible and hydrogen competes economically. However, the mainstream medium-term market is in buses, taxis, and fleet vehicles with passenger cars following close behind as the infrastructure of hydrogen filling stations becomes more widespread. It is becoming clear that the hybrid fuel cell/battery combination works best in such fleets because there is a need for batteries or supercapacitors providing pulse power and also for regenerative braking. Boats and ships represent a possible application in later years if the leisure market can be tapped and extended. In ports, fuel cell auxiliary power has already proved attractive in terms of emission reductions, and the same is true for airports. Aircraft applications will take longer to develop fully but small lightweight planes are using hydrogen at the present time because it can be generated via solar cells on the wings. Unmanned air vehicles driven by fuel cells are more likely to use propane because such lightweight fuel is easily available

Hydrogen peroxide safety issues  

SciTech Connect (OSTI)

A literature survey was conducted to review the safety issues involved in handling hydrogen peroxide solutions. Most of the information found in the literature is not directly applicable to conditions at the Rocky Flats Plant, but one report describes experimental work conducted previously at Rocky Flats to determine decomposition reaction-rate constants for hydrogen peroxide solutions. Data from this report were used to calculate decomposition half-life times for hydrogen peroxide in solutions containing several decomposition catalysts. The information developed from this survey indicates that hydrogen peroxide will undergo both homogeneous and heterogeneous decomposition. The rate of decomposition is affected by temperature and the presence of catalytic agents. Decomposition of hydrogen peroxide is catalyzed by alkalies, strong acids, platinum group and transition metals, and dissolved salts of transition metals. Depending upon conditions, the consequence of a hydrogen peroxide decomposition can range from slow evolution of oxygen gas to a vapor, phase detonation of hydrogen peroxide vapors.

Hydrogenation reactions in interstellar CO ice analogues  

E-Print Network [OSTI]

Hydrogenation reactions of CO in inter- and circumstellar ices are regarded as an important starting point in the formation of more complex species. Previous laboratory measurements by two groups on the hydrogenation of CO ices resulted in controversial results on the formation rate of methanol. Our aim is to resolve this controversy by an independent investigation of the reaction scheme for a range of H-atom fluxes and different ice temperatures and thicknesses. Reaction rates are determined by using a state-of-the-art ultra high vacuum experimental setup to bombard an interstellar CO ice analog with room temperature H atoms. The reaction of CO + H into H2CO and subsequently CH3OH is monitored by a Fourier transform infrared spectrometer in a reflection absorption mode. In addition, after each completed measurement a temperature programmed desorption experiment is performed to identify the produced species. Different H-atom fluxes, morphologies, and ice thicknesses are tested. The formation of both formaldeh...

Testing maser-based evolutionary schemes: A new search for 37.7-GHz methanol masers  

E-Print Network [OSTI]

We have used the Australia Telescope National Facility Mopra 22-m antenna to search for 37.7-GHz (7(-2) - 8(-1}E) methanol masers towards a sample of thirty six class II methanol masers. The target sources are the most luminous class II methanol masers not previously searched for this transition, with isotropic peak 12.2-GHz maser luminosity greater than 250 Jy/kpc^2 and isotropic peak 6.7-GHz maser luminosity greater than 800 Jy/kpc^2. Seven new 37.7-GHz methanol masers were detected as a result of the search. The detection rate for 37.7-GHz methanol masers towards a complete sample of all such class II methanol maser sites south of declination -20 deg is at least 30 percent. The relatively high detection rate for this rare methanol transition is in line with previous predictions that the 37.7-GHz transition is associated with a late stage of the class II methanol maser phase of high-mass star formation. We find that there is a modest correlation between the ratio of the 6.7- and 37.7-GHz maser peak intensit...

Ultrafine hydrogen storage powders  

DOE Patents [OSTI]

A method of making hydrogen storage powder resistant to fracture in service involves forming a melt having the appropriate composition for the hydrogen storage material, such, for example, LaNi.sub.5 and other AB.sub.5 type materials and AB.sub.5+x materials, where x is from about -2.5 to about +2.5, including x=0, and the melt is gas atomized under conditions of melt temperature and atomizing gas pressure to form generally spherical powder particles. The hydrogen storage powder exhibits improved chemcial homogeneity as a result of rapid solidfication from the melt and small particle size that is more resistant to microcracking during hydrogen absorption/desorption cycling. A hydrogen storage component, such as an electrode for a battery or electrochemical fuel cell, made from the gas atomized hydrogen storage material is resistant to hydrogen degradation upon hydrogen absorption/desorption that occurs for example, during charging/discharging of a battery. Such hydrogen storage components can be made by consolidating and optionally sintering the gas atomized hydrogen storage powder or alternately by shaping the gas atomized powder and a suitable binder to a desired configuration in a mold or die.

Methanol synthesis using a catalyst combination of alkali or alkaline earth salts and reduced copper chromite  

DOE Patents [OSTI]

The present invention relates to a novel route for the synthesis of methanol, and more specifically to the production of methanol by contacting synthesis gas under relatively mild conditions in a slurry phase with a catalyst combination comprising reduced copper chromite and basic alkali salts or alkaline earth salts. The present invention allows the synthesis of methanol to occur in the temperature range of approximately 100.degree.-160.degree. C. and the pressure range of 40-65 atm. The process produces methanol with up to 90% syngas conversion per pass and up to 95% methanol selectivity. The only major by-product is a small amount of easily separated methyl formate. Very small amounts of water, carbon dioxide and dimethyl ether are also produced. The present catalyst combination also is capable of tolerating fluctuations in the H.sub.2 /CO ratio without major deleterious effect on the reaction rate. Furthermore, carbon dioxide and water are also tolerated without substantial catalyst deactivation.

Development and demonstration of advanced technologies for direct electrochemical oxidation of hydrocarbons (methanol, methane, propane)  

SciTech Connect (OSTI)

Direct methanol fuel cells use methanol directly as a fuel, rather than the reformate typically required by fuel cells, thus eliminating the reformer and fuel processing train. In this program, Giner, Inc. advanced development of two types of direct methanol fuel cells for military applications. Advancements in direct methanol proton-exchange membrane fuel cell (DMPEMFC) technology included developement of a Pt-Ru anode catalyst and an associated electrode structure which provided some of the highest DMPEMFC performance reported to date. Scale-up from a laboratory-scale single cell to a 5-cell stack of practical area, providing over 100 W of power, was also demonstrated. Stable stack performance was achieved in over 300 hours of daily on/off cycling. Direct methanol aqueous carbonate fuel cells were also advanced with development of an anode catalyst and successful operation at decreased pressure. Improved materials for the cell separator/matrix and the hardware were also identified.

Enhanced self-diffusion of adsorbed methanol in silica aerogel  

Science Journals Connector (OSTI)

Molecular transport of a two-component system of liquid and vapor in a porous medium can be anomalously increased owing to fast exchange between the two phases [Phys. Rev. Lett. 63, 43 (1989)]. We have investigated this phenomenon measuring the self-diffusion coefficient of methanol adsorbed in a 98% porosity aerogel using nuclear magnetic resonance field gradient techniques. We found enhancement of several orders of magnitude from which we determined the ballistic mean-free path in the vapor phase. We have grown globally uniform anisotropic aerogels and applied the diffusion measurements to characterize the anisotropy. Our results are important for understanding the novel properties of superfluid He3 confined within an aerogel framework and for application to other physical systems.

Awaiting your repsonse Replies: I'm not quite sure what you mean by hydrogen based bacteria but I will take a stab that you mean bacteria that use hydrogen for energy. Some bacteria are chemolithotrophs which mean that they are autrophs but don't use the sun as their energy source; they get their energy from chemical sources. There are bacteria that use hydrogen as their energy source. They are diverse as a group and are all facultative. The overall chemical reaction looks like this:

SciTech Connect (OSTI)

Molecular and dissociative methanol adsorption species were prepared on rutile TiO2(110) surfaces to study photocatalytic oxidation of methanol in ultrahigh vacuum (UHV) using temperature-programmed desorption (TPD). Adsorbed methoxy groups (CH3O-) were found to be the photoactive form of adsorbed methanol converted to adsorbed formaldehyde and a surface OH group by hole-mediated C-H bond cleavage. These results suggest that adsorbed methoxy is the effective hole scavenger in photochemical reactions involving methanol.

Hydrogen Safety Knowledge Tools  

SciTech Connect (OSTI)

With hydrogen gaining acceptance as an energy carrier for fuel cell vehicles and stationary fuel cell applications, a new community of hydrogen users is emerging and continues to grow. With this growth has come the need to spread the word about safe practices for handling, storing, and using hydrogen. Like all energy forms, hydrogen can be used safely through proper procedures and engineering techniques. However, hydrogen involves a degree of risk that must be respected, and the importance of avoiding complacency or haste in the safe conduct and performance of projects involving hydrogen cannot be overstated. To encourage and promote the safe use of hydrogen, Pacific Northwest National Laboratory (PNNL) has developed and continues to enhance two software tools in support of the U.S. Department of Energy's Fuel Cell Technologies Program: the Hydrogen Safety Best Practices online manual (www.H2BestPractices.org) and the Hydrogen Incident Reporting and Lessons Learned database (www.H2Incidents.org).

Thin film hydrogen sensor  

DOE Patents [OSTI]

A hydrogen sensor element comprises an essentially inert, electrically-insulating substrate having a thin-film metallization deposited thereon which forms at least two resistors on the substrate. The metallization comprises a layer of Pd or a Pd alloy for sensing hydrogen and an underlying intermediate metal layer for providing enhanced adhesion of the metallization to the substrate. An essentially inert, electrically insulating, hydrogen impermeable passivation layer covers at least one of the resistors, and at least one of the resistors is left uncovered. The difference in electrical resistances of the covered resistor and the uncovered resistor is related to hydrogen concentration in a gas to which the sensor element is exposed.

Thermodynamics of Hydrogen Production from Dimethyl Ether Steam Reforming and Hydrolysis  

SciTech Connect (OSTI)

The thermodynamic analyses of producing a hydrogen-rich fuel-cell feed from the process of dimethyl ether (DME) steam reforming were investigated as a function of steam-to-carbon ratio (0-4), temperature (100 C-600 C), pressure (1-5 atm), and product species: acetylene, ethanol, methanol, ethylene, methyl-ethyl ether, formaldehyde, formic acid, acetone, n-propanol, ethane and isopropyl alcohol. Results of the thermodynamic processing of dimethyl ether with steam indicate the complete conversion of dimethyl ether to hydrogen, carbon monoxide and carbon dioxide for temperatures greater than 200 C and steam-to-carbon ratios greater than 1.25 at atmospheric pressure (P = 1 atm). Increasing the operating pressure was observed to shift the equilibrium toward the reactants; increasing the pressure from 1 atm to 5 atm decreased the conversion of dimethyl ether from 99.5% to 76.2%. The order of thermodynamically stable products in decreasing mole fraction was methane, ethane, isopropyl alcohol, acetone, n-propanol, ethylene, ethanol, methyl-ethyl ether and methanol--formaldehyde, formic acid, and acetylene were not observed. The optimal processing conditions for dimethyl ether steam reforming occurred at a steam-to-carbon ratio of 1.5, a pressure of 1 atm, and a temperature of 200 C. Modeling the thermodynamics of dimethyl ether hydrolysis (with methanol as the only product considered), the equilibrium conversion of dimethyl ether is limited. The equilibrium conversion was observed to increase with temperature and steam-to-carbon ratio, resulting in a maximum dimethyl ether conversion of approximately 68% at a steam-to-carbon ratio of 4.5 and a processing temperature of 600 C. Thermodynamically, dimethyl ether processed with steam can produce hydrogen-rich fuel-cell feeds--with hydrogen concentrations exceeding 70%. This substantiates dimethyl ether as a viable source of hydrogen for PEM fuel cells.

Electrochemical hydrogen Storage Systems  

SciTech Connect (OSTI)

As the global need for energy increases, scientists and engineers have found a possible solution by using hydrogen to power our world. Although hydrogen can be combusted as a fuel, it is considered an energy carrier for use in fuel cells wherein it is consumed (oxidized) without the production of greenhouse gases and produces electrical energy with high efficiency. Chemical storage of hydrogen involves release of hydrogen in a controlled manner from materials in which the hydrogen is covalently bound. Sodium borohydride and aminoborane are two materials given consideration as chemical hydrogen storage materials by the US Department of Energy. A very significant barrier to adoption of these materials as hydrogen carriers is their regeneration from 'spent fuel,' i.e., the material remaining after discharge of hydrogen. The U.S. Department of Energy (DOE) formed a Center of Excellence for Chemical Hydrogen Storage, and this work stems from that project. The DOE has identified boron hydrides as being the main compounds of interest as hydrogen storage materials. The various boron hydrides are then oxidized to release their hydrogen, thereby forming a 'spent fuel' in the form of a lower boron hydride or even a boron oxide. The ultimate goal of this project is to take the oxidized boron hydrides as the spent fuel and hydrogenate them back to their original form so they can be used again as a fuel. Thus this research is essentially a boron hydride recycling project. In this report, research directed at regeneration of sodium borohydride and aminoborane is described. For sodium borohydride, electrochemical reduction of boric acid and sodium metaborate (representing spent fuel) in alkaline, aqueous solution has been investigated. Similarly to literature reports (primarily patents), a variety of cathode materials were tried in these experiments. Additionally, approaches directed at overcoming electrostatic repulsion of borate anion from the cathode, not described in the previous literature for electrochemical reduction of spent fuels, have been attempted. A quantitative analytical method for measuring the concentration of sodium borohydride in alkaline aqueous solution has been developed as part of this work and is described herein. Finally, findings from stability tests for sodium borohydride in aqueous solutions of several different compositions are reported. For aminoborane, other research institutes have developed regeneration schemes involving tributyltin hydride. In this report, electrochemical reduction experiments attempting to regenerate tributyltin hydride from tributyltin chloride (a representative by-product of the regeneration scheme) are described. These experiments were performed in the non-aqueous solvents acetonitrile and 1,2-dimethoxyethane. A non-aqueous reference electrode for electrolysis experiments in acetonitrile was developed and is described. One class of boron hydrides, called polyhedral boranes, became of interest to the DOE due to their ability to contain a sufficient amount of hydrogen to meet program goals and because of their physical and chemical safety attributes. Unfortunately, the research performed here has shown that polyhedral boranes do not react in such a way as to allow enough hydrogen to be released, nor do they appear to undergo hydrogenation from the spent fuel form back to the original hydride. After the polyhedral boranes were investigated, the project goals remained the same but the hydrogen storage material was switched by the DOE to ammonia borane. Ammonia borane was found to undergo an irreversible hydrogen release process, so a direct hydrogenation was not able to occur. To achieve the hydrogenation of the spent ammonia borane fuel, an indirect hydrogenation reaction is possible by using compounds called organotin hydrides. In this process, the organotin hydrides will hydrogenate the spent ammonia borane fuel at the cost of their own oxidation, which forms organotin halides. To enable a closed-loop cycle, our task was then to be able to hydrogenate the organotin halides back to th

Incorporation and kinetics of hydrogen during plasma post-hydrogenation and thermal treatment are discussed for a-Si:H and a-Ge:H films. For material of low hydrogen content, the hydrogen surface concentration reached by plasma treatment equals the hydrogen concentration obtained by deposition at the same temperature and under similar plasma conditions. Enhancements of the hydrogen diffusion coefficient and of hydrogen solubility observed for plasma treatment at temperatures {le}400 C and {le}300 C for a-Si:H and a-Ge:H, respectively, are attributed to a plasma induced rise of the surface hydrogen chemical potential.

Hydrogen Storage Hydrogen Storage On the one hand, hydrogen's great asset as a renewable energy carrier is that it is storable and transportable. On the other hand, its very low natural density requires storage volumes that are impractical for vehicles and many other uses. Current practice is to compress the gas in pressurized tanks, but this still provides only limited driving range for vehicles and is bulkier than desirable for other uses as well. Liquefying the hydrogen more than doubles the fuel density, but uses up substantial amounts of energy to lower the temperature sufficiently (-253°C at atmospheric pressure), requires expensive insulated tanks to maintain that temperature, and still falls short of desired driving range. One possible way to store hydrogen at higher density is in the spaces within the crystalline

Hydrogen Fuel Quality  

SciTech Connect (OSTI)

For the past 6 years, open discussions and/or meetings have been held and are still on-going with OEM, Hydrogen Suppliers, other test facilities from the North America Team and International collaborators regarding experimental results, fuel clean-up cost, modeling, and analytical techniques to help determine levels of constituents for the development of an international standard for hydrogen fuel quality (ISO TC197 WG-12). Significant progress has been made. The process for the fuel standard is entering final stages as a result of the technical accomplishments. The objectives are to: (1) Determine the allowable levels of hydrogen fuel contaminants in support of the development of science-based international standards for hydrogen fuel quality (ISO TC197 WG-12); and (2) Validate the ASTM test method for determining low levels of non-hydrogen constituents.

Polygeneration-IGCC concepts for the production of hydrogen rich fuels based on lignite  

Science Journals Connector (OSTI)

This paper presents three IGCC-power plant concepts for central production of a hydrogen-rich fuel (methanol, hydrogen, synthetic natural gas ?? SNG) from lignite. Each concept contains a CO2-separation, which produces a sequestration-ready CO2-rich stream. Thus, CO2-emissions caused by use of lignite are considerably reduced. Furthermore, the produced low-carbon fuels are converted in decentralised Combined Heat and Power Plants (CHPP). CHPP leads to high efficiencies of fuel utilisation between 54 and 62%, which exceed the efficiencies of single power generation. Regarding to the CO2-emissions of a natural gas fired CHPP, heat and power can be generated by lignite as clean as by natural gas. The specific CO2-emissions are even much lower in the case of hydrogen production. Costs for the centrally produced methanol and hydrogen are with 29 and 19 EUR/MWh(LHV) already within an economic range. Synthetic natural gas can be produced for 23 EUR/MWh(LHV).

Precursors of the copper-zinc oxide methanol synthesis catalysts  

Science Journals Connector (OSTI)

The coprecipitated hydroxycarbonate precursor of the methanol synthesis and shift reaction catalyst based on 30 at.% copper and 70 at.% zinc oxide, which was previously reported to be a mixture of hydrozincite Zn5(CO3)2(OH)6 and rosasite (Cu,Zn)2(CO3)(OH)2 (R. G. Herman, K. Klier, G. W. Simmons, B. P. Finn, J. B. Bulko, and T. P. Kobylinski, J. Catal. 56, 407, 1979) or a single-phase hydrozincite (G. Petrini, F. Montino, A. Bossi, and G. Gaybassi, in Studies in Surface Science and Catalysis. Preparation of Catalysis III (G. Poncelet, P. Grange, and P. A. Jacobs, Eds.), Vol. 16, p. 735. Elsevier, The Netherlands, 1983), is herein shown to be a single-phase aurichalcite (Cu0.3Zn0.7)5(CO3)2(OH)6. The orthorhombic B2212 aurichalcite is crystallograpically distinct from the monoclinic \\{C2m\\} hydrozincite, although these two compounds have the same ratio of metal ions to carbonate and hydroxyl anions. Both aurichalcite and hydrozincite are chemically and structurally distinct from the monoclinic \\{P21a\\} rosasite. The earlier erroneous assignments are attributed to the structural similarity of the three hydroxycarbonates in question. An energy-dispersive characteristic X-ray emission analysis of individual particles in the scanning transmission electron microscope reveals a uniform distribution of copper and zinc at the analytical concentration CuZn = 3070. Precursors with less than 30% copper consist of mixtures of aurichalcite and hydrozincite.

SHAPE SELECTIVE NANOCATALYSTS FOR DIRECT METHANOL FUEL CELL APPLICATIONS  

SciTech Connect (OSTI)

While gold and platinum have long been recognized for their beauty and value, researchers at the Savannah River National Laboratory (SRNL) are working on the nano-level to use these elements for creative solutions to our nation's energy and security needs. Multiinterdisciplinary teams consisting of chemists, materials scientists, physicists, computational scientists, and engineers are exploring unchartered territories with shape-selective nanocatalysts for the development of novel, cost effective and environmentally friendly energy solutions to meet global energy needs. This nanotechnology is vital, particularly as it relates to fuel cells.SRNL researchers have taken process, chemical, and materials discoveries and translated them for technological solution and deployment. The group has developed state-of-the art shape-selective core-shell-alloy-type gold-platinum nanostructures with outstanding catalytic capabilities that address many of the shortcomings of the Direct Methanol Fuel Cell (DMFC). The newly developed nanostructures not only busted the performance of the platinum catalyst, but also reduced the material cost and overall weight of the fuel cell.

Low-energy electron scattering from methanol and ethanol  

Science Journals Connector (OSTI)

Measured and calculated differential cross sections for elastic (rotationally unresolved) electron scattering from two primary alcohols, methanol (CH3OH) and ethanol (C2H5OH), are reported. The measurements are obtained using the relative flow method with helium as the standard gas and a thin aperture as the collimating target gas source. The relative flow method is applied without the restriction imposed by the relative flow pressure conditions on helium and the unknown gas. The experimental data were taken at incident electron energies of 1, 2, 5, 10, 15, 20, 30, 50, and 100eV and for scattering angles of 5130. There are no previous reports of experimental electron scattering differential cross sections for CH3OH and C2H5OH in the literature. The calculated differential cross sections are obtained using two different implementations of the Schwinger multichannel method, one that takes all electrons into account and is adapted for parallel computers, and another that uses pseudopotentials and considers only the valence electrons. Comparison between theory and experiment shows that theory is able to describe low-energy electron scattering from these polyatomic targets quite well.

The effects of zirconia morphology on methanol synthesis from COand H2 over Cu/ZrO2 catalysts: Part I -- Steady-State Studies  

SciTech Connect (OSTI)

The effect of zirconia phase on the activity and selectivityof Cu/ZrO2 for the hydrogenation of CO has been investigated. Relativelypure t-ZrO2 and m-ZrO2 were prepared with high surface areas (~; 145m2/g). Copper was then deposited onto the surface of these materials byeither incipient-wetness impregnation or deposition-precipitation. For afixed Cu surface area, Cu/m-ZrO2 was tenfold more active for methanolsynthesis than Cu/t-ZrO2 from a feed of 3/1 H2/CO at 3.0 MPa andtemperatures between 473 and 523 K. Cu/m-ZrO2 also exhibited a higherselectivity to methanol. Increasing the Cu surface area on m-ZrO2resulted in further improvement in activity with minimal change inselectivity. Methanol productivity increased linearly for both Cu/t-ZrO2and Cu/m-ZrO2 with increasing Cu surface area. The difference in inherentactivity of each phase paralleled the stronger and larger CO adsorptioncapacity of the Cu/m-ZrO2 as quantified by CO-TPD. The higher COadsorption capacity of Cu/m-ZrO2 is attributed to the presence of a highconcentration of anionic vacancies on the surface of m-ZrO2. Suchvacancies expose cus-Zr4+ cations, which act as Lewis acid centers andenhance the Bronsted acidity of adjacent Zr-OH groups. The presence ofcus-Zr4+ sites and adjacent Bronsted acidic Zr-OH groups contributes tothe adsorption of CO as HCOO-Zr groups, which are the initial precursorsto methanol.

Recombination Efficiency of Molecular Hydrogen on Interstellar Grains-II A Numerical Study  

E-Print Network [OSTI]

A knowledge of the recombination time on the grain surfaces has been a major obstacle in deciding the production rate of molecular hydrogen and other molecules in the interstellar medium. We present a numerical study to compute this time for molecular hydrogen for various cloud and grain parameters. We also find the time dependence, particularly when a grain is freshly injected into the system. Apart from the fact that the recombination times seem to be functions of the grain parameters such as the activation barrier energy, temperature etc, our result also shows the dependence on the number of sites in the grain $S$ and the effective accretion rate per site $a_s$ of atomic hydrogen. Simply put, the average time that a pair of atomic hydrogens will take to produce one molecular hydrogen depends on how heavily the grain is already populated by atomic and molecular hydrogens and how fast the hopping and desorption times are. We show that if we write the average recombination time as $T_r \\sim S^\\alpha/A_H$, where, $A_H$ is the hopping rate, then $\\alpha$ could be much greater than 1 for all astrophysically relevant accretion rates. Thus the average formation rate of $H_2$ is also dependent on the grain parameters, temperature and the accretion rate. We believe that our result will affect the overall rate of the formation of complex molecules such as methanol which require successive hydrogenation on the grain surfaces in the interstellar medium.

Selective enrichment of a methanol-utilizing consortium using pulp & paper mill waste streams  

SciTech Connect (OSTI)

Efficient utilization of carbon inputs is critical to the economic viability of the current forest products sector. Input carbon losses occur in various locations within a pulp mill, including losses as volatile organics and wastewater . Opportunities exist to capture this carbon in the form of value-added products such as biodegradable polymers. Waste activated sludge from a pulp mill wastewater facility was enriched for 80 days for a methanol-utilizing consortium with the goal of using this consortium to produce biopolymers from methanol-rich pulp mill waste streams. Five enrichment conditions were utilized: three high-methanol streams from the kraft mill foul condensate system, one methanol-amended stream from the mill wastewater plant, and one methanol-only enrichment. Enrichment reactors were operated aerobically in sequencing batch mode at neutral pH and 25C with a hydraulic residence time and a solids retention time of four days. Non-enriched waste activated sludge did not consume methanol or reduce chemical oxygen demand. With enrichment, however, the chemical oxygen demand reduction over 24 hour feed/decant cycles ranged from 79 to 89 %, and methanol concentrations dropped below method detection limits. Neither the non-enriched waste activated sludge nor any of the enrichment cultures accumulated polyhydroxyalkanoates (PHAs) under conditions of nitrogen sufficiency. Similarly, the non-enriched waste activated sludge did not accumulate PHAs under nitrogen limited conditions. By contrast, enriched cultures accumulated PHAs to nearly 14% on a dry weight basis under nitrogen limited conditions. This indicates that selectively-enriched pulp mill waste activated sludge can serve as an inoculum for PHA production from methanol-rich pulp mill effluents.

The Influence of Chain Dynamics on theFar-Infrared Spectrum of Liquid Methanol  

SciTech Connect (OSTI)

Far-infrared absorption spectroscopy is used to investigate the low frequency ({center_dot} 100 cm{sup -1}) intermolecular interactions in liquid methanol. Using an intense source of far-infrared radiation, modes are elucidated at approximately 30 cm{sup -1} and 70 cm{sup -1} in the absorption spectrum. These modes are believed to arise from intermolecular bending and librational motions respectively and are successfully reproduced in an ab initio molecular dynamics simulation of methanol.

Methanol production from eucalyptus wood chips. Attachment III. Florida's eucalyptus energy farm and methanol refinery: the background environment  

SciTech Connect (OSTI)

A wide array of general background information is presented on the Central Florida area in which the eucalyptus energy plantation and methanol refinery will be located. Five counties in Central Florida may be affected by the project, DeSoto, Hardee, Hillsborough, Manatee, and Polk. The human resources of the area are reviewed. Included are overviews of population demographic and economic trends. Land use patterns and the transportation are system described, and the region's archeological and recreational resources are evaluated. The region's air quality is emphasized. The overall climate is described along with noise and air shed properties. An analysis of the region's water resources is included. Ground water is discussed first followed by an analysis of surface water. Then the overall quality and water supply/demand balance for the area is evaluated. An overview of the region's biota is presented. Included here are discussions of the general ecosystems in Central Florida, and an analysis of areas with important biological significance. Finally, land resources are examined.

Stakeholder Engagement and Outreach: Renewable Energy Supplemental  

Wind Powering America (EERE)

Renewable Energy Supplemental Environmental Projects Renewable Energy Supplemental Environmental Projects Supplemental Environmental Projects are a policy vehicle that can provide funding for renewable energy projects. Renewable energy projects can stimulate the economy, help ensure energy security, and improve the quality of the air and water. The U.S. Environmental Protection Agency designed Supplemental Environmental Projects to give companies that violate environmental regulations an alternative to standard fines. When a company violates environmental regulations, it has the option to pay a fine to the state or federal government or volunteer to fund environmentally friendly projects. These projects can provide a positive outcome for the company and the community. For more information on supplemental environmental projects,
