The Lake Charles CCS Project  

SciTech Connect

The Lake Charles CCS Project is a large-scale industrial carbon capture and sequestration (CCS) project which will demonstrate advanced technologies that capture and sequester carbon dioxide (CO{sub 2}) emissions from industrial sources into underground formations. Specifically the Lake Charles CCS Project will accelerate commercialization of large-scale CO{sub 2} storage from industrial sources by leveraging synergy between a proposed petroleum coke to chemicals plant (the LCC Gasification Project) and the largest integrated anthropogenic CO{sub 2} capture, transport, and monitored sequestration program in the U.S. Gulf Coast Region. The Lake Charles CCS Project will promote the expansion of EOR in Texas and Louisiana and supply greater energy security by expanding domestic energy supplies. The capture, compression, pipeline, injection, and monitoring infrastructure will continue to sequester CO{sub 2} for many years after the completion of the term of the DOE agreement. The objectives of this project are expected to be fulfilled by working through two distinct phases. The overall objective of Phase 1 was to develop a fully definitive project basis for a competitive Renewal Application process to proceed into Phase 2 - Design, Construction and Operations. Phase 1 includes the studies attached hereto that will establish: the engineering design basis for the capture, compression and transportation of CO{sub 2} from the LCC Gasification Project, and the criteria and specifications for a monitoring, verification and accounting (MVA) plan at the Hastings oil field in Texas. The overall objective of Phase 2, provided a successful competitive down-selection, is to execute design, construction and operations of three capital projects: (1) the CO{sub 2} capture and compression equipment, (2) a Connector Pipeline from the LLC Gasification Project to the Green Pipeline owned by Denbury and an affiliate of Denbury, and (3) a comprehensive MVA system at the Hastings oil field.

Liquefaction process  

DOE Patents (OSTI)

Scale formation during the liquefaction of lower ranking coals and similar carbonaceous materials is significantly reduced and/or prevented by pretreatment with a combination of pretreating agents comprising SO.sub.2 and an oxidizing agent. The pretreatment is believed to convert at least a portion of the scale-forming components and particularly calcium, to the corresponding sulfate prior to liquefaction. The pretreatment may be accomplished with the combination of pretreating agents either simultaneously by using a mixture comprising SO.sub.2 and an oxidizing agent or sequentially by first treating with SO.sub.2 and then with an oxidizing agent.

Liquefaction process  

DOE Patents (OSTI)

Scale formation during the liquefaction of lower ranking coals and similar carbonaceous materials is significantly reduced and/or prevented by pretreatment with a combination of pretreating agents comprising SO.sub.2 and an oxidizing agent. It is essential to effective operation that the moisture content of the solid carbonaceous material be within the range from about 10 to about 25 wt %, based on dry solid carbonaceous material, during the pretreatment. The pretreatment is believed to convert at least a portion of the scale-forming components and particularly calcium, to the corresponding sulfate prior to liquefaction. The pretreatment may be accomplished with the combination of pretreating agents either simultaneously by using a mixture comprising SO.sub.2 and a gaseous oxidizing agent or sequentially by first treating with SO.sub.2 and then with an oxidizing agent.

Coal liquefaction quenching process  

DOE Patents (OSTI)

There is described an improved coal liquefaction quenching process which prevents the formation of coke with a minimum reduction of thermal efficiency of the coal liquefaction process. In the process, the rapid cooling of the liquid/solid products of the coal liquefaction reaction is performed without the cooling of the associated vapor stream to thereby prevent formation of coke and the occurrence of retrograde reactions. The rapid cooling is achieved by recycling a subcooled portion of the liquid/solid mixture to the lower section of a phase separator that separates the vapor from the liquid/solid products leaving the coal reactor.

Coal liquefaction process  

DOE Patents (OSTI)

A process is described for the liquefaction of coal wherein raw feed coal is dissolved in recycle solvent with a slurry containing recycle coal minerals in the presence of added hydrogen at elevated temperature and pressure. The highest boiling distillable dissolved liquid fraction is obtained from a vacuum distillation zone and is entirely recycled to extinction. Lower boiling distillable dissolved liquid is removed in vapor phase from the dissolver zone and passed without purification and essentially without reduction in pressure to a catalytic hydrogenation zone where it is converted to an essentially colorless liquid product boiling in the transportation fuel range. 1 fig.

Hydrothermal Liquefaction of Biomass  

SciTech Connect

Hydrothermal liquefaction technology is describes in its relationship to fast pyrolysis of biomass. The scope of work at PNNL is discussed and some intial results are presented. HydroThermal Liquefaction (HTL), called high-pressure liquefaction in earlier years, is an alternative process for conversion of biomass into liquid products. Some experts consider it to be pyrolysis in solvent phase. It is typically performed at about 350 C and 200 atm pressure such that the water carrier for biomass slurry is maintained in a liquid phase, i.e. below super-critical conditions. In some applications catalysts and/or reducing gases have been added to the system with the expectation of producing higher yields of higher quality products. Slurry agents ('carriers') evaluated have included water, various hydrocarbon oils and recycled bio-oil. High-pressure pumping of biomass slurry has been a major limitation in the process development. Process research in this field faded away in the 1990s except for the HydroThermal Upgrading (HTU) effort in the Netherlands, but has new resurgence with other renewable fuels in light of the increased oil prices and climate change concerns. Research restarted at Pacific Northwest National Laboratory (PNNL) in 2007 with a project, 'HydroThermal Liquefaction of Agricultural and Biorefinery Residues' with partners Archer-Daniels-Midland Company and ConocoPhillips. Through bench-scale experimentation in a continuous-flow system this project investigated the bio-oil yield and quality that could be achieved from a range of biomass feedstocks and derivatives. The project was completed earlier this year with the issuance of the final report. HydroThermal Liquefaction research continues within the National Advanced Biofuels Consortium with the effort focused at PNNL. The bench-scale reactor is being used for conversion of lignocellulosic biomass including pine forest residue and corn stover. A complementary project is an international collaboration with Canada to investigate kelp (seaweed) as a biomass feedstock. The collaborative project includes process testing of the kelp in HydroThermal Liquefaction in the bench-scale unit at PNNL. HydroThermal Liquefaction at PNNL is performed in the hydrothermal processing bench-scale reactor system. Slurries of biomass are prepared in the laboratory from whole ground biomass materials. Both wet processing and dry processing mills can be used, but the wet milling to final slurry is accomplished in a stirred ball mill filled with angle-cut stainless steel shot. The PNNL HTL system, as shown in the figure, is a continuous-flow system including a 1-litre stirred tank preheater/reactor, which can be connected to a 1-litre tubular reactor. The product is filtered at high-pressure to remove mineral precipitate before it is collected in the two high-pressure collectors, which allow the liquid products to be collected batchwise and recovered alternately from the process flow. The filter can be intermittently back-flushed as needed during the run to maintain operation. By-product gas is vented out the wet test meter for volume measurement and samples are collected for gas chromatography compositional analysis. The bio-oil product is analyzed for elemental content in order to calculate mass and elemental balances around the experiments. Detailed chemical analysis is performed by gas chromatography-mass spectrometry and 13-C nuclear magnetic resonance is used to evaluate functional group types in the bio-oil. Sufficient product is produced to allow subsequent catalytic hydroprocessing to produce liquid hydrocarbon fuels. The product bio-oil from hydrothermal liquefaction is typically a more viscous product compared to fast pyrolysis bio-oil. There are several reasons for this difference. The HTL bio-oil contains a lower level of oxygen because of more extensive secondary reaction of the pyrolysis products. There are less amounts of the many light oxygenates derived from the carbohydrate structures as they have been further reacted to phenolic Aldol condensation products. The bio-oil

Bioechnology of indirect liquefaction  

DOE Green Energy (OSTI)

The project on biotechnology of indirect liquefaction was focused on conversion of coal derived synthesis gas to liquid fuels using a two-stage, acidogenic and solventogenic, anaerobic bioconversion process. The acidogenic fermentation used a novel and versatile organism, Butyribacterium methylotrophicum, which was fully capable of using CO as the sole carbon and energy source for organic acid production. In extended batch CO fermentations the organism was induced to produce butyrate at the expense of acetate at low pH values. Long-term, steady-state operation was achieved during continuous CO fermentations with this organism, and at low pH values (a pH of 6.0 or less) minor amounts of butanol and ethanol were produced. During continuous, steady-state fermentations of CO with cell recycle, concentrations of mixed acids and alcohols were achieved (approximately 12 g/l and 2 g/l, respectively) which are high enough for efficient conversion in stage two of the indirect liquefaction process. The metabolic pathway to produce 4-carbon alcohols from CO was a novel discovery and is believed to be unique to our CO strain of B. methylotrophicum. In the solventogenic phase, the parent strain ATCC 4259 of Clostridium acetobutylicum was mutagenized using nitrosoguanidine and ethyl methane sulfonate. The E-604 mutant strain of Clostridium acetobutylicum showed improved characteristics as compared to parent strain ATCC 4259 in batch fermentation of carbohydrates.

Direct coal liquefaction process  

DOE Patents (OSTI)

An improved multistep liquefaction process for organic carbonaceous mater which produces a virtually completely solvent-soluble carbonaceous liquid product. The solubilized product may be more amenable to further processing than liquid products produced by current methods. In the initial processing step, the finely divided organic carbonaceous material is treated with a hydrocarbonaceous pasting solvent containing from 10% and 100% by weight process-derived phenolic species at a temperature within the range of 300 C to 400 C for typically from 2 minutes to 120 minutes in the presence of a carbon monoxide reductant and an optional hydrogen sulfide reaction promoter in an amount ranging from 0 to 10% by weight of the moisture- and ash-free organic carbonaceous material fed to the system. As a result, hydrogen is generated via the water/gas shift reaction at a rate necessary to prevent condensation reactions. In a second step, the reaction product of the first step is hydrogenated.

Coal liquefaction with preasphaltene recycle  

SciTech Connect

A coal liquefaction system is disclosed with a novel preasphaltene recycle from a supercritical extraction unit to the slurry mix tank wherein the recycle stream contains at least 90% preasphaltenes (benzene insoluble, pyridine soluble organics) with other residual materials such as unconverted coal and ash. This subject process results in the production of asphaltene materials which can be subjected to hydrotreating to acquire a substitute for No. 6 fuel oil. The preasphaltene-predominant recycle reduces the hydrogen consumption for a process where asphaltene material is being sought.

Evaluation of liquefaction potential for building code  

Science Conference Proceedings (OSTI)

The standard approach for the evaluation of the liquefaction susceptibility is based on the estimation of a safety factor between the cyclic shear resistance to liquefaction and the earthquake induced shear stress. Recently, an updated procedure based on shear-wave velocities (V{sub s}) has been proposed which could be more easily applied.These methods have been applied at La Plaja beach of Catania, that experienced liquefaction because of the 1693 earthquake. The detailed geotechnical and V{sub s} information and the realistic ground motion computed for the 1693 event let us compare the two approaches. The successful application of the V{sub s} procedure, slightly modified to fit historical and safety factor information, even if additional field performances are needed, encourages the development of a guide for liquefaction potential analysis, based on well defined V{sub s} profiles to be included in the italian seismic code.

Iron catalyzed coal liquefaction process  

DOE Patents (OSTI)

A process is described for the solvent refining of coal into a gas product, a liquid product and a normally solid dissolved product. Particulate coal and a unique co-catalyst system are suspended in a coal solvent and processed in a coal liquefaction reactor, preferably an ebullated bed reactor. The co-catalyst system comprises a combination of a stoichiometric excess of iron oxide and pyrite which reduce predominantly to active iron sulfide catalysts in the reaction zone. This catalyst system results in increased catalytic activity with attendant improved coal conversion and enhanced oil product distribution as well as reduced sulfide effluent. Iron oxide is used in a stoichiometric excess of that required to react with sulfur indigenous to the feed coal and that produced during reduction of the pyrite catalyst to iron sulfide.

Investigations into coal coprocessing and coal liquefaction  

DOE Green Energy (OSTI)

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expected to improve the liquid yield through more efficient dispersion of an oil-soluble, iron-based catalyst, (2) to characterize the coke deposits on novel, supported catalysts after coal liquefaction experiments and to correlate the carbon skeletal structure parameters of the coke deposit with catalyst performance as measured by coal liquefaction product yield, and (3) to determine the modes of hydrogen utilization during coal liquefaction and coprocessing. Experimental results are discussed in this report.

Advanced liquefaction using coal swelling and catalyst dispersion techniques. Quarterly technical progress report No. 7, April 1993--June 1993  

Science Conference Proceedings (OSTI)

The overall objective of this project is to develop a new approach for the direct liquefaction of coal to produce an all-distillate product slate at a sizable cost reduction over current technology. The approach integrates coal selection, pretreatment, coal swelling with catalyst impregnation, liquefaction, product recovery with characterization, alternate bottoms processing, and carrying out a technical assessment including an economic evaluation. The project is being carried out under contract to the United States Department of Energy. All three coals used in this study (Black Thunder, Burning Star bituminous, and Martin Lake lignite) are effectively swelled by a number of solvents. The most effective solvents are those having hetero-functionality. In addition, a synergistic effect has been demonstrated, in which solvent blends are more effective for coal swelling than the pure solvents alone. Therefore, it will be necessary to use only low levels of swelling agents and yet promote the impregnation of catalyst precursors. The rate of the impregnation of catalyst precursors into swollen coal increases greatly as the effectiveness of the solvent to swell the coal increases. This effect is also demonstrated by improved catalyst precursor impregnation with increased contact temperature. Laboratory- and bench-scale liquefaction experimentation is underway using swelled and catalyst impregnated coal samples. Higher coal conversions were observed for the SO{sub 2}-treated coal than the raw coal, regardless of catalyst type. Conversions of swelled coal were highest when Molyvan-L, molybdenum naphthenate, and nickel octoate, respectively, were added to the liquefaction solvent.

Catalyst for coal liquefaction process  

SciTech Connect

An improved catalyst for a coal liquefaction process; e.g., the H-Coal Process, for converting coal into liquid fuels, and where the conversion is carried out in an ebullated-catalyst-bed reactor wherein the coal contacts catalyst particles and is converted, in addition to liquid fuels, to gas and residual oil which includes preasphaltenes and asphaltenes. The improvement comprises a catalyst selected from the group consisting of the oxides of nickel molybdenum, cobalt molybdenum, cobalt tungsten, and nickel tungsten on a carrier of alumina, silica, or a combination of alumina and silica. The catalyst has a total pore volume of about 0.500 to about 0.900 cc/g and the pore volume comprises micropores, intermediate pores and macropores, the surface of the intermediate pores being sufficiently large to convert the preasphaltenes to asphaltenes and lighter molecules. The conversion of the asphaltenes takes place on the surface of micropores. The macropores are for metal deposition and to prevent catalyst agglomeration. The micropores have diameters between about 50 and about 200 angstroms (.ANG.) and comprise from about 50 to about 80% of the pore volume, whereas the intermediate pores have diameters between about 200 and 2000 angstroms (.ANG.) and comprise from about 10 to about 25% of the pore volume, and the macropores have diameters between about 2000 and about 10,000 angstroms (.ANG.) and comprise from about 10 to about 25% of the pore volume. The catalysts are further improved where they contain promoters. Such promoters include the oxides of vanadium, tungsten, copper, iron and barium, tin chloride, tin fluoride and rare earth metals.

Coal liquefaction process streams characterization and evaluation  

DOE Green Energy (OSTI)

This study clearly demonstrated the usefulness of liquid- and solid-state {sup 13}C- and {sup 1}H-NMR for the examination of process-derived materials from direct coal liquefaction. The techniques can provide data not directly obtainable by other methods to examine the saturation of aromatic rings and to determine the modes of hydrogen utilization during coal liquefaction. In addition, these methods can be used to infer the extent of condensation and retrograde reactions occurring in the direct coal liquefaction process. Five NMR techniques were employed. Solid-state {sup 13}C-NMR measurements were made using the Cross Polarization Magic Angle Spinning (CP/MAS) and Single Pulse (SP) techniques. Solid-state {sup 1}H-NMR measurements were made using the technique of Combined Rotation and Multiple-Pulse spectroscopy (CRAMPS). Conventional liquid-state {sup 12}C- and {sup 1}H-NMR techniques were employed as appropriate. Interpretation of the NMR data, once obtained, is relatively straightforward. Combined with other information, such as elemental analyses and process conversion data, the NMR data prove to be a powerful tool for the examination of direct coal liquefaction process-derived material. Further development and more wide-spread application of this analytical method as a process development tool is justified on the basis of these results.

Mild coal pretreatment to improve liquefaction reactivity  

SciTech Connect

This report describes work completed during the fourth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. This work is part of a larger effort to develop a new coal liquefaction or coal/oil coprocessing scheme consisting of three main process steps: (1) mile pretreatment of the feed coal to enhance dissolution reactivity and dry the coal, (2) low severity thermal dissolution of the pretreated coal to obtain a very reactive coal-derived residual material amenable to upgrading, and (3) catalytic upgrading of the residual products to distillate liquids.

Indirect liquefaction of biomass: A fresh approach  

DOE Green Energy (OSTI)

Indirect liquefaction of biomass is accomplished by first gasifying it to produce a synthesis gas consisting of hydrogen and oxides of carbon, which in turn are converted to any one of a number of liquid fuels and/or chemicals by suitable choice of catalyst, synthesis gas composition and reaction conditions. This approach to producing synthetic fuels and chemicals has been extensively investigated where coal is the carbonaceous feed material, but less so for biomass or other feedstocks. It is generally recognized that the gasification to produce the synthesis gas posses one of the major technical and economic challenges to improving this technology. Herein, is reported a different slant on the indirect liquefaction that could lead to improvements in the efficiency and economics of the process.

Direct liquefaction proof-of-concept program  

DOE Green Energy (OSTI)

The POC Bench Option Project (PB-Series) is geared to evaluate different novel processing concepts in catalytic direct coal liquefaction and coprocessing of organic wastes such as plastics, heavy resids, waste oils, and ligno-cellulose wastes with coal. The new ideas being explored in this program include using novel dispersed slurry catalysts and combinations of dispersed and supported catalysts (hybrid mode), and coprocessing of coal with waste plastics, low quality resids, waste oils, and ligno-cellulosic wastes, etc. The primary objective of bench run PB-07 was to study the impact of dispersed catalyst composition and loading upon the direct liquefaction performance of a high volatile bituminous Illinois No. 6 coal. The run was carried out for 20 operating days (including the four days used for the production of O-6 bottoms material for West Virginia University), spanning over five process conditions. Results are reported.

Whole Algae Hydrothermal Liquefaction Technology Pathway  

SciTech Connect

In support of the Bioenergy Technologies Office, the National Renewable Energy Laboratory (NREL) and the Pacific Northwest National Laboratory (PNNL) are undertaking studies of biomass conversion technologies to hydrocarbon fuels to identify barriers and target research toward reducing conversion costs. Process designs and preliminary economic estimates for each of these pathway cases were developed using rigorous modeling tools (Aspen Plus and Chemcad). These analyses incorporated the best information available at the time of development, including data from recent pilot and bench-scale demonstrations, collaborative industrial and academic partners, and published literature and patents. This pathway case investigates the feasibility of using whole wet microalgae as a feedstock for conversion via hydrothermal liquefaction. Technical barriers and key research needs have been assessed in order for the hydrothermal liquefaction of microalgae to be competitive with petroleum-derived gasoline, diesel and jet range blendstocks.

Coal liquefaction process with increased naphtha yields  

DOE Patents (OSTI)

An improved process for liquefying solid carbonaceous materials wherein the solid carbonaceous material is slurried with a suitable solvent and then subjected to liquefaction at elevated temperature and pressure to produce a normally gaseous product, a normally liquid product and a normally solid product. The normally liquid product is further separated into a naphtha boiling range product, a solvent boiling range product and a vacuum gas-oil boiling range product. At least a portion of the solvent boiling-range product and the vacuum gas-oil boiling range product are then combined and passed to a hydrotreater where the mixture is hydrotreated at relatively severe hydrotreating conditions and the liquid product from the hydrotreater then passed to a catalytic cracker. In the catalytic cracker, the hydrotreater effluent is converted partially to a naphtha boiling range product and to a solvent boiling range product. The naphtha boiling range product is added to the naphtha boiling range product from coal liquefaction to thereby significantly increase the production of naphtha boiling range materials. At least a portion of the solvent boiling range product, on the other hand, is separately hydrogenated and used as solvent for the liquefaction. Use of this material as at least a portion of the solvent significantly reduces the amount of saturated materials in said solvent.

Coal liquefaction process streams characterization and evaluation  

Science Conference Proceedings (OSTI)

Under contract from the DOE , and in association with CONSOL Inc., Battelle, Pacific Northwest Laboratory (PNL) evaluated four principal and several complementary techniques for the analysis of non-distillable direct coal liquefaction materials in support of process development. Field desorption mass spectrometry (FDMS) and nuclear magnetic resonance (NMR) spectroscopic methods were examined for potential usefulness as techniques to elucidate the chemical structure of residual (nondistillable) direct coal liquefaction derived materials. Supercritical fluid extraction (SFE) and supercritical fluid chromatography/mass spectrometry (SFC/MS) were evaluated for effectiveness in compound-class separation and identification of residual materials. Liquid chromatography (including microcolumn) separation techniques, gas chromatography/mass spectrometry (GC/MS), mass spectrometry/mass spectrometry (MS/MS), and GC/Fourier transform infrared (FTIR) spectroscopy methods were applied to supercritical fluid extracts. The full report authored by the PNL researchers is presented here. The following assessment briefly highlights the major findings of the project, and evaluates the potential of the methods for application to coal liquefaction materials. These results will be incorporated by CONSOL into a general overview of the application of novel analytical techniques to coal-derived materials at the conclusion of CONSOL's contract.

Coal-tire co-liquefaction  

Science Conference Proceedings (OSTI)

Co-liquefaction of ground coal and tire rubber was studied at 400{degrees}C both with and without catalyst. Two different tire samples were used. In the non-catalytic runs, the conversion of coal increased with the addition of tire and the increase was dependent on tire/coal ratio and hydrogen pressure. Using a ferric sulfide-based catalyst, the coal conversion increased with an increase in the catalyst loading. However, the increase was more pronounced at loadings of around 0.5 wt%. The addition of tire to coal in the catalytic runs was not particularly beneficial, especially, when the tire/coal ratio was above 1.

Direct liquefaction proof-of-concept facility  

DOE Green Energy (OSTI)

The main objective of the U.S. DOE, Office of Fossil Energy, is to ensure the US a secure energy supply at an affordable price. An integral part of this program was the demonstration of fully developed coal liquefaction processes that could be implemented if market and supply considerations so required, Demonstration of the technology, even if not commercialized, provides a security factor for the country if it is known that the coal to liquid processes are proven and readily available. Direct liquefaction breaks down and rearranges complex hydrocarbon molecules from coal, adds hydrogen, and cracks the large molecules to those in the fuel range, removes hetero-atoms and gives the liquids characteristics comparable to petroleum derived fuels. The current processes being scaled and demonstrated are based on two reactor stages that increase conversion efficiency and improve quality by providing the flexibility to adjust process conditions to accommodate favorable reactions. The first stage conditions promote hydrogenation and some oxygen, sulfur and nitrogen removal. The second stage hydrocracks and speeds the conversion to liquids while removing the remaining sulfur and nitrogen. A third hydrotreatment stage can be used to upgrade the liquids to clean specification fuels.

Combustion, pyrolysis, gasification, and liquefaction of biomass  

DOE Green Energy (OSTI)

All the products now obtained from oil can be provided by thermal conversion of the solid fuels biomass and coal. As a feedstock, biomass has many advantages over coal and has the potential to supply up to 20% of US energy by the year 2000 and significant amounts of energy for other countries. However, it is imperative that in producing biomass for energy we practice careful land use. Combustion is the simplest method of producing heat from biomass, using either the traditional fixed-bed combustion on a grate or the fluidized-bed and suspended combustion techniques now being developed. Pyrolysis of biomass is a particularly attractive process if all three products - gas, wood tars, and charcoal - can be used. Gasification of biomass with air is perhaps the most flexible and best-developed process for conversion of biomass to fuel today, yielding a low energy gas that can be burned in existing gas/oil boilers or in engines. Oxygen gasification yields a gas with higher energy content that can be used in pipelines or to fire turbines. In addition, this gas can be used for producing methanol, ammonia, or gasoline by indirect liquefaction. Fast pyrolysis of biomass produces a gas rich in ethylene that can be used to make alcohols or gasoline. Finally, treatment of biomass with high pressure hydrogen can yield liquid fuels through direct liquefaction.

Mild coal pretreatment to improve liquefaction reactivity  

SciTech Connect

This report describes work completed during the fifth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. Work this quarter focused on analytical characterization of untreated and treated Wyodak subbituminous coal and Illinois {number sign}6 bituminous coal. Mossbauer spectroscopy and x-ray diffraction techniques were used to study the effect of methanol/HCl pretreatment on the composition of each coal's inorganic phase. Results from these studies indicated that calcite is largely removed during pretreatment, but that other mineral species such as pyrite are unaffected. This finding is significant, since calcite removal appears to directly correlate with low severity liquefaction enhancement. Further work will be performed to study this phenomenon in more detail.

Novel experimental studies for coal liquefaction  

DOE Green Energy (OSTI)

Two studies related to coal liquefaction were carried out. The major effort in study was to investigate experimentally a novel reaction sequence for conversion of synthesis gas to methanol. The reaction studied in this work takes place in the liquid phase and consists of two reactions occurring in series. In the first, methanol is carbonylated to methyl formate using a homogeneous catalyst and then the formate is hydrogenated to two molecules of methanol using a heterogeneous catalyst. The reactions were studied individually and then concurrently (both reactions taking place in the same slurry reactor). A modeling study of the non-isothermal unsteady state Fischer-Tropsch reaction was carried out. In the second study the use of supercritical water for extraction and conversion of coal and oil shale was investigated. The two primary goals were to study the kinetics and mass transfer differences between conventional and supercritical liquefaction. The kinetic effects were studied by liquefying coal in supercritical toluene. Mass transfer studies were carried out on a model system consisting of naphthalene and supercritical carbon dioxide. 64 refs.

Coal liquefaction process streams characterization and evaluation  

DOE Green Energy (OSTI)

This study demonstrated the feasibility of using temperature-programmed electron spin resonance (ESR) and thermogravimetric analysis (TGA) for the examination of tetrahydrofuran (THF)-soluble distillation resid materials derived from direct coal liquefaction. TGA is used to quantitate volatile losses in a temperature-programmed experiment. The TGA data are used to correct the free radical densities obtained by ESR as volatile material is evolved from the samples in the temperature-programmed ESR experiment. The techniques, when employed in tandem, can be used to determine the content and nature of the free radicals in the samples at temperatures approximating those used in the liquefaction process. TGA and ESR experiments were performed in flowing nitrogen and hydrogen, at ambient pressure. No significant difference was observed in the ESR spectra in the different atmospheres, except in the case of low-rank coal-derived resids. The TGA results, however, were systematically different; mass loss in an H[sub 2] atmosphere is consistently higher than that observed in an N[sub 2] atmosphere. It was shown that temperature-programmed ESR, which can pinpoint conditions at which the free radical content is the highest, has potential to be a guide for the appropriate choice of conditions for optimum resid upgrading. Further development of these combined analytical methods as process development tools appears justified based on these results.

Bioechnology of indirect liquefaction. Final report  

DOE Green Energy (OSTI)

The project on biotechnology of indirect liquefaction was focused on conversion of coal derived synthesis gas to liquid fuels using a two-stage, acidogenic and solventogenic, anaerobic bioconversion process. The acidogenic fermentation used a novel and versatile organism, Butyribacterium methylotrophicum, which was fully capable of using CO as the sole carbon and energy source for organic acid production. In extended batch CO fermentations the organism was induced to produce butyrate at the expense of acetate at low pH values. Long-term, steady-state operation was achieved during continuous CO fermentations with this organism, and at low pH values (a pH of 6.0 or less) minor amounts of butanol and ethanol were produced. During continuous, steady-state fermentations of CO with cell recycle, concentrations of mixed acids and alcohols were achieved (approximately 12 g/l and 2 g/l, respectively) which are high enough for efficient conversion in stage two of the indirect liquefaction process. The metabolic pathway to produce 4-carbon alcohols from CO was a novel discovery and is believed to be unique to our CO strain of B. methylotrophicum. In the solventogenic phase, the parent strain ATCC 4259 of Clostridium acetobutylicum was mutagenized using nitrosoguanidine and ethyl methane sulfonate. The E-604 mutant strain of Clostridium acetobutylicum showed improved characteristics as compared to parent strain ATCC 4259 in batch fermentation of carbohydrates.

The Liquefaction of Hydrogen and Helium Using Small Coolers  

DOE Green Energy (OSTI)

This report discusses the history of the liquefaction of hydrogen and helium using small coolers. This history dates form the 1960's when two stage GM coolers capable of reaching 7 K were used to liquefy helium and hydrogen by suing an added compressor and J-T circuit. Liquefaction using the added circuit failed to become mainstream because the J-T valve and heat exchanger clogged because of impurities in the gas being liquefied. Liquefaction using a GM cooler without an added J-T circuit proved to be difficult because the first stage was not used to pre-cool the gas coming to the second stage of the cooler. Once the gas being liquefied was pre-cooled using the cooler first stage, improvements in the liquefaction rates were noted. The advent of low temperature pulse tube cooler (down to 2.5 K) permitted one to achieve dramatic improvement is the liquefactions rates for helium. Similar but less dramatic improvements are expected for hydrogen as well. Using the PT-415 cooler, one can expect liquefaction rates of 15 to 20 liters per day for helium or hydrogen provided the heat leak into the cooler and the storage vessel is low. A hydrogen liquefier for MICE is presented at the end of this report.

Integrated coal cleaning, liquefaction, and gasification process  

DOE Patents (OSTI)

Coal is finely ground and cleaned so as to preferentially remove denser ash-containing particles along with some coal. The resulting cleaned coal portion having reduced ash content is then fed to a coal hydrogenation system for the production of desirable hydrocarbon gases and liquid products. The remaining ash-enriched coal portion is gasified to produce a synthesis gas, the ash is removed from the gasifier usually as slag, and the synthesis gas is shift converted with steam and purified to produce the high purity hydrogen needed in the coal hydrogenation system. This overall process increases the utilization of as-mined coal, reduces the problems associated with ash in the liquefaction-hydrogenation system, and permits a desirable simplification of a liquids-solids separation step otherwise required in the coal hydrogenation system.

Process for coal liquefaction in staged dissolvers  

SciTech Connect

There is described an improved liquefaction process by which coal is converted to a low ash and low sulfur carbonaceous material that can be used as a fuel in an environmentally acceptable manner without costly gas scrubbing equipment. In the process, coal is slurried with a pasting oil, passed through a preheater and at least two dissolvers in series in the presence of hydrogen-rich gases at elevated temperatures and pressures. Solids, including mineral ash and unconverted coal macerals, are separated from the condensed reactor effluent. In accordance with the improved process, the first dissolver is operated at a higher temperature than the second dissolver. This temperature sequence produces improved product selectivity and permits the incorporation of sufficient hydrogen in the solvent for adequate recycle operations.

Co-liquefaction of the Elbistan Lignite and Poplar Sawdust. Part I: The Effect of the Liquefaction Parameters  

SciTech Connect

In this study, the liquefaction of Elbistan lignite and poplar sawdust, and the co-liquefaction of the Elbistan lignite and the poplar sawdust in an inert atmosphere and in non-catalytic conditions have been examined. Also, the effects of solvent/coal ratio and stirring speed on the total conversion derived as the result of the liquefaction process was attempted to be determined. Based on the results, although the effects of the solvent/coal ratio and the stirring speed on total conversion are similar for both the Elbistan lignite and the poplar sawdust, it was also noted that, under similar conditions, the conversion for the poplar sawdust was higher, as compared to the conversion of the Elbistan lignite. As the result of the liquefaction of Elbistan lignite and poplar sawdust under inert atmospheric conditions, the total conversion was increased partially, depending on both solvent/coal ratio and the speed of stirring. However, it was also noted that the total conversion did not change to a significant extent in high solvent/coal ratios and in stirring speed. As the result of the co-liquefaction of the Elbistan lignite and poplar sawdust under inert atmospheric conditions, total conversion was increased, based on the solvent/coal ratio. However, as in the case of the liquefaction of Elbistan lignite and poplar sawdust, it was noted that the high solvent/coal ratios (i.e., solvent/coal ratios of higher than 2/1) did not have a significant effect on the total conversion that was derived as the result of the co-liquefaction of the Elbistan lignite and poplar sawdust.

This is the eleventh Quarterly Technical Progress Report under DOE Contract DE-AC22-89PC89883. Major topics reported are: (1) The results of a study designed to determine the effects of the conditions employed at the Wilsonville slurry preheater vessel on coal conversion is described. (2) Stable carbon isotope ratios were determined and used to source the carbon of three product samples from Period 49 of UOP bench-scale coprocessing Run 37. The results from this coprocessing run agree with the general trends observed in other coprocessing runs that we have studied. (3) Microautoclave tests and chemical analyses were performed to calibrate'' the reactivity of the standard coal used for determining donor solvent quality of process oils in this contract. (4) Several aspects of Wilsonville Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) resid conversion kinetics were investigated; results are presented. Error limits associated with calculations of deactivation rate constants previously reported for Runs 258 and 261 are revised and discussed. A new procedure is described that relates the conversions of 850[degrees]F[sup +] , 1050[degrees]F[sup +], and 850 [times] 1050[degrees]F material. Resid conversions and kinetic constants previously reported for Run 260 were incorrect; corrected data and discussion are found in Appendix I of this report.

Liquefaction process for solid carbonaceous materials containing alkaline earth metal humates  

DOE Patents (OSTI)

An improved liquefaction process wherein wall scale and particulate agglomeration during the liquefaction of solid carbonaceous materials containing alkaline earth metal humates is reduced and/or eliminated by subjecting the solid carbonaceous materials to controlled cyclic cavitation during liquefaction. It is important that the solid carbonaceous material be slurried in a suitable solvent or diluent during liquefaction. The cyclic cavitation may be imparted via pressure cycling, cyclic agitation and the like. When pressure cycling or the like is employed an amplitude equivalent to at least 25 psia is required to effectively remove scale from the liquefaction vessel walls.

Donor solvent coal liquefaction with bottoms recycle at elevated pressure  

DOE Patents (OSTI)

An improved process for liquefying solid carbonaceous materials wherein increased naphtha yields are achieved by effecting the liquefaction at a pressure within the range from about 1750 to about 2800 psig in the presence of recycled bottoms and a hydrogen-donor solvent containing at least 0.8 wt % donatable hydrogen. The liquefaction is accomplished at a temperature within the range from about 700.degree. to about 950.degree. F. The coal:bottoms ratio in the feed to liquefaction will be within the range from about 1:1 to about 5:1 and the solvent or diluent to total solids ratio will be at least 1.5:1 and preferably within the range from about 1.6:1 to about 3:1. The yield of naphtha boiling range materials increases as the pressure increases but generally reaches a maximum at a pressure within the range from about 2000 to about 2500 psig.

A method of dispersing a liquefaction catalyst within coal or other carbonaceous solids involves providing a suspension in oil of microcapsules containing the catalyst. An aqueous solution of a catalytic metal salt is emulsified in the water-immiscible oil and the resulting minute droplets microencapsulated in polymeric shells by interfacial polycondensation. The catalyst is subsequently blended and dispersed throughout the powdered carbonaceous material to be liquefied. At liquefaction temperatures the polymeric microcapsules are destroyed and the catalyst converted to minute crystallites in intimate contact with the carbonaceous material. 2 tables.

Surface Modified Coals for Enhanced Catalyst Dispersion and Liquefaction  

SciTech Connect

The aim of this study is to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants and catalysts on to the coal. During this reporting period, liquefaction experiments were conducted with the raw coal and catalyst loaded samples. Pretreatment of the coal and catalyst-loaded samples were done using the surfactants presented in previous reports. Liquefaction samples were tested using 6.6 g of solvent, 3.3 g coal, 6.9 MPa ambient hydrogen pressure, 425 0 C and 30 minutes. The liquid and solid products were removed from the reactor using tetrahydrofuran (THF). Coal conversions were calculated based on THF and heptane solubility. The results showed that in the absence of a catalyst, 33.8% heptane solubles was obtained with the parent coal compared to 27.8% and 27.3% with the SDS and DDAB surfactants. The presence of molybdenum, as expected, resulted in enhanced heptane solubles with or without surfactants. In the absence of surfactants, 50% heptane solubles was obtained compared to 40-47% with surfactants. Thus, it appears that pretreatment, unexpectedly, had a negative effect on liquefaction activity. It is unclear if the observed differences in results are significant. Clearly, additional experiments are needed before any firm deductions and conclusions can be drawn from the results.

SHORT CONTACT TIME DIRECT COAL LIQUEFACTION USING A NOVEL BATCH REACTOR  

DOE Green Energy (OSTI)

The overall goal of this research is to develop an understanding of the Direct Coal Liquefaction process at the molecular level. Many approaches have been used to study this process including kinetic studies, study of the liquefaction products, study of the effect of reaction variables, such as temperature, solvent type and composition, the changing nature and composition of the coal during liquefaction, and the distribution in the liquefaction products of the hydrogen consumed. While all these studies have contributed to our growing knowledge of the liquefaction process, an adequate understanding of direct liquefaction still eludes us. This is due to many reasons including: the complexity and variable nature of coal itself and the many different chemical reactions which are occurring simultaneously during direct coal liquefaction. We believe that a study of the liquefaction process at the very early stages will avoid the complexities of secondary reactions associated with free radical high temperature processes that are clearly involved in direct coal liquefaction. This prompted us to devise a reactor system which avoids long heat up and cool-down times associated with previous kinetic studies, and allows kinetic measurements even at as short as the first few seconds of the liquefaction reaction.

Process for coal liquefaction employing selective coal feed  

DOE Patents (OSTI)

An improved coal liquefaction process is provided whereby coal conversion is improved and yields of pentane soluble liquefaction products are increased. In this process, selected feed coal is pulverized and slurried with a process derived solvent, passed through a preheater and one or more dissolvers in the presence of hydrogen-rich gases at elevated temperatures and pressures, following which solids, including mineral ash and unconverted coal macerals, are separated from the condensed reactor effluent. The selected feed coals comprise washed coals having a substantial amount of mineral matter, preferably from about 25-75%, by weight, based upon run-of-mine coal, removed with at least 1.0% by weight of pyritic sulfur remaining and exhibiting vitrinite reflectance of less than about 0.70%.

Liquefaction of remote sources of natural gas. Final report  

SciTech Connect

The objective was to determine the technical and financial feasibility of liquefying remote reserves of natural gas and transporting the liquefied product to users. The proposed methodology included efforts to (1) identify any prohibitive or limiting laws and/or regulations; (2) identify sufficient unutilized reserves in remote areas to justify further investigation; (3) identify existing portable liquefaction equipment (or an interested manufacturer that could supply the needed equipment) to obtain cost and performance data; (4) determine site preparation, supply and production costs for use in assessing economic feasibility; and (5) identify potential users. The conclusion is that the liquefaction of natural gas in remote areas of Appalachia is not economically feasible as long as an adequate and reliable supply of pipeline gas is perceived to be available for the forseable future and the price per Btu of pipeline gas remains so far below other fuels. 3 tables.

Control of pyrite addition in coal liquefaction process  

SciTech Connect

Pyrite addition to a coal liquefaction process (22, 26) is controlled (118) in inverse proportion to the calcium content of the feed coal to maximize the C.sub.5 --900.degree. F. (482.degree. C.) liquid yield per unit weight of pyrite added (110). The pyrite addition is controlled in this manner so as to minimize the amount of pyrite used and thus reduce pyrite contribution to the slurry pumping load and disposal problems connected with pyrite produced slag.

STUDY OF SOLVENT AND CATALYST INTERACTIONS IN DIRECT COAL LIQUEFACTION  

SciTech Connect

Major objectives of the present project are to develop a better understanding of the roles of the catalyst and the liquefaction solvent in the coal liquefaction process. An open question concerning the role of the catalyst is whether intimate contact between the catalyst and the coal particles is important or required. To answer this question, it had been planned to coat an active catalyst with a porous silica coating which was found to retain catalyst activity while preventing actual contact between catalyst and coal. Consultation with people in DuPont who coat catalysts for increasing abrasion resistance have indicated that only portions of the catalyst are coated by their process (spray drying) and that sections of uncoated catalyst remain. For that reason, it was decided to suspend the catalyst in a basket separated from the coal in the reactor. The basket walls were to be permeable to the liquefaction solvent but not to the coal particles. Several such baskets were constructed of stainless steel with holes which would not permit passage of coal particles larger than 30 mesh. Liquefactions run with the coal of greater than 30 mesh size gave normal conversion of coal to liquid in the absence of catalyst in the basket, but substantially increased conversion when Ni/Mo on alumina catalyst was in the basket. While this result is interesting and suggestive of some kind of mass transfer of soluble material occurring between the catalyst and the coal, it does not eliminate the possibility of breakdown of the coal particle into particle sizes permeable to the basket. Indeed, a small amount of fine coal has been found inside the basket. To determine whether fine coal from breakdown of the coal particles is responsible for the conversion, a new basket is being prepared with 0.5{micro}m pore size.

Development of an extruder-feeder biomass direct liquefaction process  

DOE Green Energy (OSTI)

As an abundant, renewable, domestic energy resource, biomass could help the United States reduce its dependence on imported oil. Biomass is the only renewable energy technology capable of addressing the national need for liquid transportation fuels. Thus, there is an incentive to develop economic conversion processes for converting biomass, including wood, into liquid fuels. Through research sponsored by the US DOE's Biomass Thermochemical Conversion Program, the University of Arizona has developed a unique biomass direct liquefaction system. The system features a modified single-screw extruder capable of pumping solid slurries containing as high as 60 wt % wood flour in wood oil derived vacuum bottoms at pressures up to 3,000 psi. By comparison, conventional pumping systems are capable of pumping slurries containing only 10--20 wt % wood flour in wood oil under similar conditions. The extruder-feeder has been integrated with a unique reactor to form a system which offers potential for improving high pressure biomass direct liquefaction technology. The extruder-feeder acts simultaneously as both a feed preheater and a pumping device for injecting wood slurries into a 3,000 psi pressure reactor in the biomass liquefaction process. An experimental facility was constructed during 1983--84. Following shakedown operations, wood crude oil was produced by mid-1985. During the period January 1985 through July 1988, a total of 57 experimental continuous biomass liquefaction runs were made using White Birch wood feedstock. Good operability was achieved at slurry feed rates up to 30 lb/hr, reactor pressures from 800 to 3,000 psi and temperatures from 350{degrees}C to 430{degrees}C under conditions covering a range of carbon monoxide feed rates and sodium carbonate catalyst addition. Crude wood oils containing as little as 6--10 wt % residual oxygen were produced. 43 refs., 81 figs., 52 tabs.

Evaluation of wastewater treatment requirements for thermochemical biomass liquefaction  

DOE Green Energy (OSTI)

The broad range of processing conditions involved in direct biomass liquefaction lead to a variety of product properties. The aqueous byproduct streams have received limited analyses because priority has been placed on analysis of the complex organic liquid product. The range of organic contaminants carried in the aqueous byproducts directly correlates with the quantity and quality of contaminants in the liquid oil product. The data in the literature gives a general indication of the types and amounts of components expected in biomass liquefaction wastewater; however, the data is insufficient to prepare a general model that predicts the wastewater composition from any given liquefaction process. Such a model would be useful in predicting the amount of water that would be soluble in a given oil and the level of dissolved water at which a second aqueous-rich phase would separate from the oil. Both biological and thermochemical processes have proposed for wastewater treatment, but no treatment process has been tested. Aerobic and anaerobic biological systems as well as oxidative and catalytic reforming thermochemical systems should be considered.

SURFACE-MODIFIED COALS FOR ENHANCED CATALYST DISPERSION AND LIQUEFACTION  

SciTech Connect

This is the final report of the Department of Energy Sponsored project DE-FGF22-95PC95229 entitled, surface modified coals for enhanced catalyst dispersion and liquefaction. The aims of the study were to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants and catalysts on the coal and to train and educate minority scientists in catalysts and separation science. Illinois No. 6 Coal (DEC-24) was selected for the study. The surfactants investigated included dodecyl dimethyl ethyl ammonium bromide (DDAB), a cationic surfactant, sodium dodecyl sulfate, an anionic surfactant, and Triton x-100, a neutral surfactant. Ammonium molybdate tetrahydrate was used as the molybdenum catalyst precursor. Zeta potential, BET, FTIR, AFM, UV-Vis and luminescence intensity measurements were undertaken to assess the surface properties and the liquefaction activities of the coal. The parent coal had a net negative surface charge over the pH range 2-12. However, in the presence of DDAB the negativity of the surface charge decreased. At higher concentrations of DDAB, a positive surface charge resulted. In contrast to the effect of DDAB, the zeta potential of the coal became more negative than the parent coal in the presence of SDS. Adsorption of Triton reduced the net negative charge density of the coal samples. The measured surface area of the coal surface was about 30 m{sup 2}/g compared to 77m{sup 2}/g after being washed with deionized water. Addition of the surfactants decreased the surface area of the samples. Adsorption of the molybdenum catalyst increased the surface area of the coal sample. The adsorption of molybdenum on the coal was significantly promoted by preadsorption of DDAB and SDS. Molybdenum adsorption showed that, over a wide range of concentrations and pH values, the DDAB treated coal adsorbed a higher amount of molybdenum than the samples treated with SDS. The infrared spectroscopy (FTIR) and the atomic force microscopy (AFM) also provided evidence that confirmed the adsorption of the surfactants onto the coal surface. The luminescence measurements showed that the coal and solid surfactants luminescence weakly. No statistically significant influence was observed that resulted from the action of the surfactants or surfactant-molybdenum catalyst. Interestingly, the liquefaction results produced data that indicated the use of surfactants did not significantly improve the liquefaction activity of the coal as had initially been hypothesized. The UV-adsorption tests provided evidence that suggest that this may have been due to oversaturation. Detailed discussions of the results and recommendations for future work are provided.

Liquefaction of calcium-containing subbituminous coals and coals of lower rank  

DOE Patents (OSTI)

An improved process for the treatment of a calcium-containing subbituminous coal and coals of lower rank to form insoluble, thermally stable calcium salts which remain within the solids portions of the residue on liquefaction of the coal, thereby suppressing the formation of scale, made up largely of calcium carbonate which normally forms within the coal liquefaction reactor (i.e., coal liquefaction zone), e.g., on reactor surfaces, lines, auxiliary equipment and the like. An oxide of sulfur, in liquid phase, is contacted with a coal feed sufficient to impregnate the pores of the coal. The impregnated coal, in particulate form, can thereafter be liquefied in a coal liquefaction reactor (reaction zone) at coal liquefaction conditions without significant formation of scale.

The fish in this tiny like are plentiful and HUGE :) Bass up to 20" s (so far) and blue gill up to 10"s (so far). My question is this... we appear to have a heavy goose population and I was wondering if they are the cause of the green slimmy stuff that is all over the top of the water as well as the lighter green slime on the plants growing under the water? Are the fish being harmed by waste from the geese and if so, what can I put in the water to ensure their health? Additionally, I noticed hundreds of frogs during the mating period yet I've yet to see even one tad pole and I am at the lake atleast 5 out of the 7 days in a week. Is there a reason for this. The frogs are two toned.. light green with patches of darker shades of green on the head and body. I've never seen frogs like these before but then again, I've never lived in wet lands prior. The frogs are also very agressive... tend to attack fishing line and even leap up to 4' in the air to attack a fishing rod. Thank heavens they don't have teeth! . We do not keep the fish we catch, we always release.

Direct liquefaction proof-of-concept program. Topical report  

DOE Green Energy (OSTI)

This report presents the results of work conducted under the DOE Proof-of-Concept Program in direct coal liquefaction at Hydrocarbon Technologies, Inc. in Lawrenceville, New Jersey, from February 1994 through April 1995. The work includes modifications to HRI`s existing 3 ton per day Process Development Unit (PDU) and completion of the second PDU run (POC Run 2) under the Program. The 45-day POC Run 2 demonstrated scale up of the Catalytic Two-Stage Liquefaction (CTSL Process) for a subbituminous Wyoming Black Thunder Mine coal to produce distillate liquid products at a rate of up to 4 barrels per ton of moisture-ash-free coal. The combined processing of organic hydrocarbon wastes, such as waste plastics and used tire rubber, with coal was also successfully demonstrated during the last nine days of operations of Run POC-02. Prior to the first PDU run (POC-01) in this program, a major effort was made to modify the PDU to improve reliability and to provide the flexibility to operate in several alternative modes. The Kerr McGee Rose-SR{sup SM} unit from Wilsonville, Alabama, was redesigned and installed next to the U.S. Filter installation to allow a comparison of the two solids removal systems. The 45-day CTSL Wyoming Black Thunder Mine coal demonstration run achieved several milestones in the effort to further reduce the cost of liquid fuels from coal. The primary objective of PDU Run POC-02 was to scale-up the CTSL extinction recycle process for subbituminous coal to produce a total distillate product using an in-line fixed-bed hydrotreater. Of major concern was whether calcium-carbon deposits would occur in the system as has happened in other low rank coal conversion processes. An additional objective of major importance was to study the co-liquefaction of plastics with coal and waste tire rubber with coal.

Evaluation of wastewater treatment requirements for thermochemical biomass liquefaction  

DOE Green Energy (OSTI)

Biomass can provide a substantial energy source. Liquids are preferred for use as transportation fuels because of their high energy density and handling ease and safety. Liquid fuel production from biomass can be accomplished by any of several different processes including hydrolysis and fermentation of the carbohydrates to alcohol fuels, thermal gasification and synthesis of alcohol or hydrocarbon fuels, direct extraction of biologically produced hydrocarbons such as seed oils or algae lipids, or direct thermochemical conversion of the biomass to liquids and catalytic upgrading to hydrocarbon fuels. This report discusses direct thermochemical conversion to achieve biomass liquefaction and the requirements for wastewater treatment inherent in such processing. 21 refs.

Liquefaction of calcium-containing subbituminous coals and coals of lower rank  

DOE Patents (OSTI)

A process for the treatment of a calcium-containing subbituminous coal and coals of lower rank to form insoluble, thermally stable calcium salts which remain within the solids portions of the residue on liquefaction of the coal, thereby suppressing the formation scale, made up largely of calcium carbonate deposits, e.g., vaterite, which normally forms within the coal liquefaction reactor (i.e., coal liquefaction zone), e.g., on reactor surfaces, lines, auxiliary equipment and the like. A solution of a compound or salt characterized by the formula MX, where M is a Group IA metal of the Periodic Table of the Elements, and X is an anion which is capable of forming water-insoluble, thermally stable calcium compounds, is maintained in contact with a particulate coal feed sufficient to impregnate said salt or compound into the pores of the coal. On separation of the impregnated particulate coal from the solution, the coal can be liquefied in a coal liquefaction reactor (reaction zone) at coal liquefaction conditions without significant formation of vaterite or other forms of calcium carbonate on reactor surfaces, auxiliary equipment and the like; and the Group IA metal which remains within the liquefaction bottoms catalyzes the reaction when the liquefaction bottoms are subjected to a gasification reaction.

Coal liquefaction process streams characterization and evaluation. Volume 1, Base program activities  

Science Conference Proceedings (OSTI)

This 4.5-year project consisted of routine analytical support to DOE`s direct liquefaction process development effort (the Base Program), and an extensive effort to develop, demonstrate, and apply new analytical methods for the characterization of liquefaction process streams (the Participants Program). The objective of the Base Program was to support the on-going DOE direct coal liquefaction process development program. Feed, process, and product samples were used to assess process operations, product quality, and the effects of process variables, and to direct future testing. The primary objective of the Participants Program was to identify and demonstrate analytical methods for use in support of liquefaction process development, and in so doing, provide a bridge between process design, and development, and operation and analytical chemistry. To achieve this objective, novel analytical methods were evaluated for application to direct coal liquefaction-derived materials. CONSOL teamed with 24 research groups in the program. Well-defined and characterized samples of coal liquefaction process-derived materials were provided to each group. CONSOL made an evaluation of each analytical technique. During the performance of this project, we obtained analyses on samples from numerous process development and research programs and we evaluated a variety of analytical techniques for their usefulness in supporting liquefaction process development. Because of the diverse nature of this program, we provide here an annotated bibliography of the technical reports, publications, and formal presentations that resulted from this program to serve as a comprehensive summary of contract activities.

Effects of low-temperature catalytic pretreatments on coal structure and reactivity in liquefaction  

SciTech Connect

This work is a fundamental study of catalytic pretreatments as a potential preconversion step to low-severity liquefaction. The ultimate goal of this work is to provide the basis for the design of an improved liquefaction process and to facilitate our understanding of those processes that occur when coals are initially dissolved. The main objectives of this project are to study the effects of low-temperature pretreatments on coal structure and their impacts on the subsequent liquefaction. The effects of pretreatment temperatures, catalyst type, coal rank and influence of solvent will be examined. We have made significant progress in the following four aspects during this quarterly period: (1) influence of drying and oxidation of coal on the conversion and product distribution in catalytic liquefaction of Wyodak subbituminous coal using a dispersed catalyst; (2) spectroscopic characterization of dried and oxidized Wyodak coal and the insoluble residues from catalytic and thermal liquefaction; (3) the structural alteration of low-rank coal in low-severity liquefaction with the emphasis on the oxygen-containing functional groups; and (4) effects of solvents and catalyst dispersion methods in temperature-programmed and non-programmed liquefaction of three low-rank coals.

Coal liquefaction process streams characterization and evaluation: FT-IR methods for characterization of coal liquefaction products  

DOE Green Energy (OSTI)

This study was designed to demonstrate the use of two FTIR techniques for the analysis of direct coal liquefaction process-derived materials. The two methods were quantitative FTIR analysis and themogravimetric (TG) analysis with FTIR analysis of evolved products (TG-FTIR). The quantitative FTIR analyses of both whole resids and THF-soluble resids provided quantitation of total hydrogen, aliphatic and aromatic hydrogen, total carbon, total oxygen, hydroxyl and etheric oxygen, and ash contents. The FTIR results were usually in agreement with values derived by other, more conventional methods. However, the accuracies of specific measurements, in comparisons with results from conventional methods, ranged from good to poor. The TG-FTIR method provided approximate analyses of coals and resids. The data provided included the time dependent evolution profiles of the volatile species and the elemental composition of the char. Reproducible data of gaseous species and pyrolysis tar yields for whole resid samples larger than 10 mg were obtainable. The yields and evolution profiles of certain volatiles (tar, CO, and methane) provided structural information on the samples. There were some experimental and interpretational difficulties associated with both techniques. Optimization of the curve-resolving routine for coal-liquefaction samples would improve the quantitative FTIR accuracy. Aerosol formation limited the full application of the TG-FTIR technique with the THF-soluble resid samples. At this time, further development of these analytical methods as process development tools will be required before their use for that purpose can be recommended. The use of FTIR as an on-line analytical technique for coal liquefaction process streams requires demonstration before it can be recommended; however, such a demonstration may be warranted.

Subtask 3.9 - Direct Coal Liquefaction Process Development  

Science Conference Proceedings (OSTI)

The Energy and Environmental Research Center (EERC), in partnership with the U.S. Department of Energy (DOE) and Accelergy Corporation, an advanced fuels developer with technologies exclusively licensed from ExxonMobil, undertook Subtask 3.9 to design, build, and preliminarily operate a bench-scale direct coal liquefaction (DCL) system capable of converting 45 pounds/hour of pulverized, dried coal to a liquid suitable for upgrading to fuels and/or chemicals. Fabrication and installation of the DCL system and an accompanying distillation system for off-line fractionation of raw coal liquids into 1) a naphtha?middle distillate stream for upgrading and 2) a recycle stream was completed in May 2012. Shakedown of the system was initiated in July 2012. In addition to completing fabrication of the DCL system, the project also produced a 500-milliliter sample of jet fuel derived in part from direct liquefaction of Illinois No. 6 coal, and submitted the sample to the Air Force Research Laboratory (AFRL) at Wright? Patterson Air Force Base, Dayton, Ohio, for evaluation. The sample was confirmed by AFRL to be in compliance with all U.S. Air Force-prescribed alternative aviation fuel initial screening criteria.

Indirect thermal liquefaction process for producing liquid fuels from biomass  

DOE Green Energy (OSTI)

A progress report on an indirect liquefaction process to convert biomass type materials to quality liquid hydrocarbon fuels by gasification followed by catalytic liquid fuels synthesis has been presented. A wide variety of feedstocks can be processed through the gasification system to a gas with a heating value of 500 + Btu/SCF. Some feedstocks are more attractive than others with regard to producing a high olefin content. This appears to be related to hydrocarbon content of the material. The H/sub 2//CO ratio can be manipulated over a wide range in the gasification system with steam addition. Some feedstocks require the aid of a water-gas shift catalyst while others appear to exhibit an auto-catalytic effect to achieve the conversion. H/sub 2/S content (beyond the gasification system wet scrubber) is negligible for the feedstocks surveyed. The water gas shift reaction appears to be enhanced with an increase in pyrolysis reactor temperature over the range of 1300 to 1700/sup 0/F. Reactor temperature in the Fischer-Tropsch step is a significant factor with regard to manipulating product composition analysis. The optimum temperature however will probably correspond to maximum conversion to liquid hydrocarbons in the C/sub 5/ - C/sub 17/ range. Continuing research includes integrated system performance assessment, alternative feedstock characterization (through gasification) and factor studies for gasification (e.g., catalyst usage, alternate heat transfer media, steam usage, recycle effects, residence time study) and liquefaction (e.g., improved catalysts, catalyst activity characterization).

Coal liquefaction process streams characterization and evaluation: The preliminary evaluation of the kinetics of coal liquefaction distillation resid conversion  

SciTech Connect

This study evaluated the use of a novel laboratory-scale batch reactor, designed by the University of Delaware, to study the kinetics of coal liquefaction resid reactivity. The short time batch reactor (STBR) is capable of conducting reactions at temperatures up to 450{degrees}C and pressures up to 2500 psi at well-defined reaction times from a few seconds to 30 min or longer. Sixty experiments were conducted with the STBR in this project. The products of the resid/tetralin/hydrogen reaction were separated by solubility, and several analytical procedures were used to evaluate the reaction products, including thermogravimetric analysis (TGA), gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Changes were monitored in the boiling ranges of the products, as a function of process conditions (time, temperature, and tetralin donor solvent-to-resid ratio), with and without catalysts. Two distillation resid samples were studied; Sample 1 is the resid of the second stage product stream from Wilsonville Run 259 which used Pittsburgh seam coal (Ireland mine) bituminous coal, and Sample 2 is the resid of the same streak from Wilsonville Run 260 which used Wyodak and Anderson (Black Thunder Mine) subbituminous coal. It was determined that the resid reactivity was different for the two samples studied. The results demonstrate that further development of this experimental method is warranted to empirically assess resid reactivity and to provide data for use in the construction of an empirical model of coal conversion in the direct liquefaction process.

Coal liquefaction process streams characterization and evaluation. Characterization of coal liquefaction resids employing thermogravimetric analysis and electron spin resonance spectroscopy  

DOE Green Energy (OSTI)

This study demonstrated the feasibility of using temperature-programmed electron spin resonance (ESR) and thermogravimetric analysis (TGA) for the examination of tetrahydrofuran (THF)-soluble distillation resid materials derived from direct coal liquefaction. TGA is used to quantitate volatile losses in a temperature-programmed experiment. The TGA data are used to correct the free radical densities obtained by ESR as volatile material is evolved from the samples in the temperature-programmed ESR experiment. The techniques, when employed in tandem, can be used to determine the content and nature of the free radicals in the samples at temperatures approximating those used in the liquefaction process. TGA and ESR experiments were performed in flowing nitrogen and hydrogen, at ambient pressure. No significant difference was observed in the ESR spectra in the different atmospheres, except in the case of low-rank coal-derived resids. The TGA results, however, were systematically different; mass loss in an H{sub 2} atmosphere is consistently higher than that observed in an N{sub 2} atmosphere. It was shown that temperature-programmed ESR, which can pinpoint conditions at which the free radical content is the highest, has potential to be a guide for the appropriate choice of conditions for optimum resid upgrading. Further development of these combined analytical methods as process development tools appears justified based on these results.

Preconversion processing of bituminous coals: New directions to improved direct catalytic coal liquefaction. [High temperature soaking coal in coal liquids prior to liquefaction  

SciTech Connect

Soaking coal in coal liquids at 300-400[degrees]C (high-tenperature soaking) has been studied for coal dissolution prior to liquefaction in the previous task. Two high-volatile bituminous coals, Illinois No. 6 and Pittsburgh No. 8, were examined in three different coal liquids. The high-temperature soaking was effective to solubilize more than 70 wt% cf these coals. The mechanism of disintegration of coal by the high-temperature soaking was investigated under various soaking conditions. The products was also analyzed with solvent swelling. These results were rationalized that coal is solubilized primarily by physical disintegration. The derived mechanism was consistent with the new concept of coal structure: A significant portion of coal is physically associated, not three-dimensionally cross-linked. Radically-induced scission reactions were proposed to prorate breakage of coal moleculs by the combination of the high-temperature soaking before liquefaction. In this term, the effect of radical initiators were investigated under the conditions of the high-temperature soaking and liquefaction. Illinois No. 6 coal and a coal liquid derived from the same coal were used. The first section reports the effect of radical initiators on coal disintegration, and the second section reports the effect of a radical initiator on coal liquefaction. Radical initiators had a positive effect on disintegration. However, the effect was highly temperature-dependent and had a negative effect on liquefaction at high tenperatures.

Subtask 3.3 - Feasibility of Direct Coal Liquefaction in the Modern Economic Climate  

SciTech Connect

Coal liquefaction provides an alternative to petroleum for the production of liquid hydrocarbon-based fuels. There are two main processes to liquefy coal: direct coal liquefaction (DCL) and indirect coal liquefaction (ICL). Because ICL has been demonstrated to a greater extent than DCL, ICL may be viewed as the lower-risk option when it comes to building a coal liquefaction facility. However, a closer look, based on conversion efficiencies and economics, is necessary to determine the optimal technology. This report summarizes historical DCL efforts in the United States, describes the technical challenges facing DCL, overviews Shenhua's current DCL project in China, provides a DCL conceptual cost estimate based on a literature review, and compares the carbon dioxide emissions from a DCL facility to those from an ICL facility.

The role of recycle oil in direct coal liquefaction process development  

Science Conference Proceedings (OSTI)

It has long been recognized that use of a recycle oil is a convenient and perhaps necessary feature of a practical direct coal liquefaction process. The recycle oil performs a number of important functions. It serves as a vehicle to convey coal into the liquefaction reactor and products from the reactor. It is a medium for mass and heat transfer among the solid, liquid, and gaseous components of the reactor inventory. It can act as a reactant or intermediate in the liquefaction process. Therefore, the nature of the recycle oil can have a determining effect on process configuration and performance, and the characterization of recycle oil composition and chemistry has been the subject of considerable interest. This paper discusses recycle oil characterization and its influence on the industrial development of coal liquefaction technology,

Hydrothermal pretreatment to prevent scale during liquefaction of certain solid carbonaceous materials  

DOE Patents (OSTI)

Scale formation during the liquefaction of lower ranking coals and similar carbonaceous materials is significantly reduced and/or prevented by hydrothermal pretreatment. The said pretreatment is believed to convert the scale-forming components to the corresponding carbonate prior to liquefaction. The said pretreatment is accomplished at a total pressure within the range from about 1000 to about 4400 psia. Temperature during said pretreatment will generally be within the range from about 500.degree. to about 700.degree. F.

Effects of low-temperature catalytic pretreatments on coal structure and reactivity in liquefaction  

Science Conference Proceedings (OSTI)

Low-temperature catalytic pretreatment is a promising approach to the development of an improved liquefaction process- This work is a fundamental study on effects of pretreatments on coal structure and reactivity in liquefaction. The main objectives of this project are to study the coal structural changes induced by low-temperature catalytic and thermal pretreatments by using spectroscopic techniques; and to clarify the pretreatment-induced changes in reactivity or convertibility of coals in the subsequent liquefaction. This report describes the recent progress of our work. Substantial progress has been made in the spectroscopic characterization of structure and pretreatment-liquefaction reactions of a Montana subbituminous Coal (DECS-9), and thermochemical analysis of three mw and reacted bituminous coals. Temperature programmed liquefaction has been performed on three low-rank coals both in the presence and absence of dispersed molybdenum sulfide catalyst. We also performed a detailed study of the effects of mild thermal pretreatment -- drying in air and in vacuum -- on thermal and catalytic liquefaction of a Wyodak subbituminous coal. Important information on structure and structure transformation during thermal pretreatment and liquefaction reactions of low-rank coals has been derived by applying solid-state CPMAS [sup 13]C NMR and flash pyrolysis-GC-MS (Py-GC-MS) for characterization of the macromolecular network of a Montana subbituminous coal and its residues from temperature-programmed and nonprogrammed liquefaction (TPL and N-PL) at final temperatures ranging from 300 to 425[degree]C in H-donor and non-donor solvents. The results revealed that this coal contains significant quantities of oxygen-bearing structures, corresponding to about 18 O-bound C per 100 C atoms and one O-bound C per every 5 to 6 aromatic C.

Coal liquefaction. Quarterly report, October-December 1978  

SciTech Connect

DOE's program for the conversion of coal to liquid fuels was begun by two of DOE's predecessor agencies: Office of Coal Research (OCR) in 1962, and ERDA. The Bureau of Mines, US Department of the Interior, had started work in the 1930's. Current work is aimed at improved process configurations for both catalytic and noncatalytic processes to provide more attractive processing economics and lower capital investment. The advantage of coal liquefaction is that the entire range of liquid products, especially boiler fuel, distillate fuel oil, and gasoline, can be produced from coal by varying the type of process and operating conditions used in the process. Furthermore, coal-derived liquids have the potential for use as chemical feedstocks. To provide efficient and practical means of utilizing coal resources, DOE is supporting the development of several conversion processes that are currently in the pilot plant stage. Each of these processes are described briefly.

The technical feasibility study of using selective agglomeration (with coal-derived oil) to upgrade Illinois No. 6 coal for a liquefaction feedstock was completed. Effects of coal particle size, slurry pH, oil-to-coal ratio, and operating temperature on mineral matter reduction, clean coal weight recovery, and clean coal moisture content were studied. The addition of coal-derived naphtha or kerosene as conditioners to increase hydrophobicity and recovery of coal was also investigated. Results showed that approximately 70% of the mineral matter could be removed from this coal at a clean coal weight recovery of over 85% by grinding the coal to a mean volume diameter of about 10 microns and properly selecting of the operation variables.

Changes in hydrogen utilization with temperature during direct coal liquefaction  

Science Conference Proceedings (OSTI)

A reliable means of monitoring the major pathways of hydrogen utilization, in contrast to only measuring net hydrogen comsumption, would be very useful for process optimization. The goal of this work was to develop an analytical approach for quantitatively distinguishing hydrogen consumed in hydrogenation from that utilized to stabilize thermolysis fragments. The approach outlined yields a rather detailed description of the net utilization of hydrogen during direct liquefaction, partitioning it into contributions from gas generation, heteroatom removal, hydrogenation, and matrix breakdown. Preliminary results indicate that internal hydrogen reorganization, with little consumption, predominates at low temperatures, with hydrogenation being compensated for by the hydrogen liberated in condensations. As the temperature is increased, bond cleavage reactions and aromatization reactions appear to become more important, and the net hydrogen consumption increases. (3 tables 1 figs., 11 refs.)

Advanced direct liquefaction concepts for PETC generic units. Quarterly technical progress report, October 1992--December 1992  

DOE Green Energy (OSTI)

The reactivity of the THF insoluble fraction of the ashy resid component of Wilsonville recycle oil (WRO) during liquefaction of Black Thunder coal in tetralin was determined at 415{degrees}C and 60 minutes. The liquefaction runs were made by combining this material with Black Thunder coal at the same ratio used in the WRO coal runs. THF conversion and product distribution from liquefaction in tetralin in the presence of the THF insoluble fraction of the ashy resid were similar to results from liquefaction in WRO. THF conversion was greater than loot with an oil yield that was somewhat higher than in WRO. Differences in HC gas yield and H{sub 2} consumption were slight, while conversion and product distribution from liquefaction of Black Thunder coal in tetralin or in the WRO distillate were quite different. In both these solvents the 85--86% THF conversions were less than for runs in which the THF insoluble fraction of the ashy resid was present. This establishes that the THF insoluble fraction of the ashy resid is the reactive fraction of the WRO.

Catalyst dispersion and activity under conditions of temperature- staged liquefaction  

DOE Green Energy (OSTI)

The general objectives of this research are (1) to investigate the use of highly dispersed catalysts for the pretreatment of coal by mild hydrogenation, (2) to identify the active forms of the catalysts under reaction conditions and (3) to clarify the mechanisms of catalysis. The ultimate objective is to ascertain if mild catalytic hydrogenation resulting in very limited or no coal solubilization is an advantageous pretreatment for the transformation of coal into transportable fuels. The experimental program will focus upon the development of effective methods of impregnating coal with catalysts, evaluating the conditions under which the catalysts are most active and establishing the relative impact of improved impregnation on conversion and product distributions obtained from coal hydrogenation. Liquefaction experiments of solvent-treated and untreated Blind Canyon (DECS-6) and Texas lignite (DECS-1) have been performed using ammonium tetrathiomolybdate (ATTM) and bis (dicarbonylcyclopentadienyl) iron (CPI) as catalyst precursors using temperature-staged conditions (275{degrees}C, 30 min; 425{degrees}C, 30 min). Solid state {sup 13}C NMR analysis was carried out for each coal and for selected residues. 12 refs., 14 figs., 9 tabs.

Opportunities for reducing product costs in indirect liquefaction  

Science Conference Proceedings (OSTI)

The MITRE indirect liquefaction simulation model for the advanced configuration that includes Shell gasification and slurry-phase F-T synthesis was downsized to coincide with the Bechtel/Amoco conceptual plant with a nominal capacity of 50,000 barrels per stream day. Then the kinetic parameters used by Bechtel/Amoco in the slurry F-T model were substituted in the model. This resulted in the same per pass conversion and in the same number of reactors as estimated in the Bechtel basecase. The total capital cost for this plant was estimated to be $2982 million using the MITRE model. This agrees well with the preliminary Bechtel/Amoco capital cost of $2961 million for the same size plant(3). Once the WM simulation of the basecase plant was shown to be in agreement with the Bechtel/Amoco case, the analysis of further potential cost reductions beyond the basecase could be investigated. This analysis only investigated the potential cost reductions that could result from improvements in the F-T area of the conceptual plant. This is the area that is impacted by the research and development underway in the indirect program. The cost impact of the following potential improvements were investigated using the MITRE simulation model: Doubling the baseline catalyst activity; doubling the catalyst loading; and doubling the superficial gas velocity.

A CHARACTERIZATION AND EVALUATION OF COAL LIQUEFACTION PROCESS STREAMS  

DOE Green Energy (OSTI)

This is the Technical Progress Report for the fifteenth quarter of activities under DOE Contract No. DE-AC22-94PC93054. It covers the period January 1 through March 31, 1998. Described in this report are the following activities: (1) CONSOL characterized 41 process stream samples obtained from HTI Run PB-01 (227-90), in which Black Thunder Mine coal, Hondo VTB resid, municipal solid waste (MSW) plastics, and virgin plastics were co-liquefaction feedstocks with all-dispersed Fe and Mo catalysts. (2) A request was made for samples from the Nippon Coal Oil NEDOL pilot plant in Kashima, Japan. (3) Phenols were extracted from two samples of separator overhead oil from HTI Run PB-03 Periods 10A and 10B. The phenols were converted to ethylphenyl ethers, and the ethers were distilled to produce a sample within the diesel fuel boiling range. The ethers were mixed with diesel fuel to make 1%, 5%, 10%, and 20% solutions. The four mixtures and a control sample (0% ether) were tested for diesel fuel properties by Intertek Testing Services, Caleb Brett. (4) Computational studies related to the University of Delaware's resid conversion model were continued on the Hewlett Packard Apollo HP-735 RISC workstation at CONSOL R and D. The Structure Optimization Program and the Structure Once-Through Program were used to generate physicochemical properties and structure models for the 15 coal resid samples which have been under study.

Preconversion processing of bituminous coals: New directions to improved direct catalytic coal liquefaction  

SciTech Connect

Improved coal liquefaction was reinvestigated for the current two-stage process on the basis of the associated molecular nature of coal. Since a significant portion of coal molecules are physically associated as pointed in our recent paper, physical dissolution should be considered. The step-wise, high-temperature soaking is a simple and effective method for coal dissolution. Larger dissolution makes liquefaction severity lower. Broad molecular mass distribution in the associated coal was another important factor. The selective reaction of fractions with high molecular weight isolated after the high-temperature soaking makes gas yield lower. Tests using an autoclave by the concept shown in Figure 5 enabled to more oil and 15-20% less gas yields. It is expected that the procedure will result in great cost reduction in coal liquefaction.

Co-conversion of coal/waste plastic mixtures under various pyrolysis and liquefaction conditions  

Science Conference Proceedings (OSTI)

For strategic and economic reasons the conversion of coal to liquid fuels has been a constant goal of the coal science community. Although the economics of coal liquefaction are primarily governed by the price of crude oil, other factors such as the need for large quantities of hydrogen gas, play an important role. If methods could be found that reduce the amount of hydrogen gas required for liquefaction, considerable benefits would be realized. To explore this possibility the use of waste plastics as materials capable of upgrading coal into liquid fuel products has been investigated. The use of waste plastics for this purpose could become possible because over 30 million tons of synthetic polymer material is produced in the United States every year. In this study, several pyrolysis and liquefaction experiment were performed on an Illinois No. 6 coal and coal/plastic blends.

SUMMARY REPORT OF THE DOE DIRECT LIQUEFACTION PROCESS DEVELOPMENT CAMPAIGN OF THE LATE TWENTIETH CENTURY  

SciTech Connect

Following the petroleum price and supply disruptions of 1973, the U.S. government began a substantial program to fund the development of alternative fuels. Direct coal liquefaction was one of the potential routes to alternative fuels. The direct coal liquefaction program was funded at substantial levels through 1982, and at much lower levels thereafter. Those processes that were of most interest during this period were designed to produce primarily distillate fuels. By 1999, U.S. government funding for the development of direct coal liquefaction ended. Now that the end of this campaign has arrived, it is appropriate to summarize the process learnings derived from it. This report is a summary of the process learnings derived from the DOE direct coal liquefaction process development campaign of the late twentieth century. The report concentrates on those process development programs that were designed to produce primarily distillate fuels and were largely funded by DOE and its predecessors in response to the petroleum supply and price disruptions of the 1970s. The report is structured as chapters written by different authors on most of the major individual DOE-funded process development programs. The focus of the report is process learnings, as opposed to, say, fundamental coal liquefaction science or equipment design. As detailed in the overview (Chapter 2), DOE's direct coal liquefaction campaign made substantial progress in improving the process yields and the quality of the distillate product. Much of the progress was made after termination by 1983 of the major demonstration programs of the ''first generation'' (SRC-II, H-Coal, EDS) processes.

The Behavior of Lakes  

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

Behavior of Lakes Behavior of Lakes Nature Bulletin No, 320-A November 9, 1968 Forest Preserve District of Cook County Richard B. Ogilvie, President Roland F. Eisenbeis, Supt. of Conservation THE BEHAVIOR OF LAKES In many ways lakes are like living things -- especially a tree. A lake breathes and has a circulation; it is warmed and fed; it harbors many other living things; and in cold weather it goes into a winter sleep. If it were not for the special character of a body of standing water which we call a lake, the things that live in it would be radically different or, perhaps, not exist at all. Water is a very strange substance in many ways. For example, it is remarkable because it expands, becomes lighter and floats when it freezes into ice. If, like most substances, water shrank when it changed from a liquid to a solid, it would sink. Then, ponds and lakes would freeze from the bottom up and become solid blocks of ice. This would make life impossible for most kinds of aquatic plants and animals and indirectly affect all living things. Further, water is a poor conductor of heat -- otherwise lakes would freeze much deeper and, again most living things in it would perish.

The Wilsonville Advanced Coal Liquefaction Research and Development Facility, Wilsonville, Alabama  

SciTech Connect

The investigation of various Two-Stage Liquefaction (TSL) process configurations was conducted at the Wilsonville Advanced Coal Liquefaction R D Facility between July 1982 and September 1986. The facility combines three process units. There are the liquefaction unit, either thermal (TLU) or catalytic, for the dissolution of coal, the Critical Solvent Deashing unit (CSD) for the separation of ash and undissolved coal, and a catalytic hydrogenation unit (HTR) for product upgrading and recycle process solvent replenishment. The various TSL process configurations were created by changing the process sequence of these three units and by recycling hydrotreated solvents between the units. This report presents a description of the TSL configurations investigated and an analysis of the operating and performance data from the period of study. Illinois No. 6 Burning Star Mine coal Wyodak Clovis Point Mine coal were processed. Cobalt-molybdenum and disposable iron-oxide catalysts were used to improve coal liquefaction reactions and nickel-molybdenum catalysts were used in the hydrotreater. 28 refs., 31 figs., 13 tabs.

Determination of unconverted HDPE in coal/plastics co-liquefaction stream samples  

DOE Green Energy (OSTI)

In several coal/plastics liquefaction runs performed by Hydrocarbon Technologies, Inc. (HTI), a substantial amount of incompletely converted high-density polyethylene (HDPE) was present in ash-free recycle resid streams when either the ROSE-SR unit was used in Run POC-2, or the pressure filter unit was used in Runs CMSL-8 and CMSL-9. This indicates that the HDPE is less reactive than coal at the liquefaction conditions used. In these ash-free streams, there is no solid organic or inorganic material arising from the coal, and the incompletely converted HDPE can be recovered by extraction and filtration with tetrahydrofuran (THF) at room temperature. The HDPE (or HDPE-like material, which could also consist of heavy waxes) is THF insoluble. However, in ashy streams, there are both inorganic ({open_quotes}ash{close_quotes}) and organic (unconverted coal) components present from liquefaction of the coal, that interfere with an easy and clean separation of the HDPE from the coal/plastics liquefaction stream sample. Therefore, CONSOL developed an analytical procedure for HDPE in the ashy stream samples based on extraction of HDPE from the sample using hot (150{degrees}C) decalin (decahydronaphthalene), in which the HDPE is soluble. The decalin extraction is both preceded and succeeded by extractions and washes with THF at room temperature, to remove the coal-derived components from the sample.

Status of health and environmental research relative to direct coal liquefaction: 1976 to the present  

Science Conference Proceedings (OSTI)

This document describes the status of health and environmental research efforts, supported by the US Department of Energy (DOE), to assist in the development of environmentally acceptable coal liquefaction processes. Four major direct coal liquefaction processes are currently in (or have been investigated at) the pilot plant stage of development. Two solvent refined coal processes (SRC-I and -II), H-coal (a catalytic liquefaction process) and Exxon donor solvent (EDS). The Pacific Northwest Laboratory was assigned responsibility for evaluating SRC process materials and prepared comprehensive health and environmental effects research program plans for SRC-I and -II. A similar program plan was prepared for H-coal process materials by the Oak Ridge National Laboratory. A program has been developed for EDS process materials by Exxon Research and Engineering Co. The program includes short-term screening of coal-derived materials for potential health and ecological effects. Longer-term assays are used to evaluate materials considered most representative of potential commercial practice and with greatest potential for human exposure or release to the environment. Effects of process modification, control technologies and changing operational conditions on potential health and ecological effects are also being evaluated. These assessments are being conducted to assist in formulating cost-effective environmental research programs and to estimate health and environmental risks associated with a large-scale coal liquefaction industry. Significant results of DOE's health and environmental research efforts relative to coal liquefaction include the following: chemical characterization, health effects, ecological fate and effects, amelioration and risk assessment.

SciTech Connect

This report presents the results of bench-scale work, Bench Run PB-04, conducted under the DOE Proof of Concept-Bench Option Program in direct coal liquefaction at Hydrocarbon Technologies, Inc. in Lawrenceville, New Jersey. The Bench Run PB-04 was the fifth of the nine runs planned in the POC Bench Option Contract between the U.S. DOE and Hydrocarbon Technologies, Inc. Bench Run PB-04 had multiple goals. These included the evaluation of the effects of dispersed slurry catalyst system on the performance of direct liquefaction of a subbituminous Wyoming Black Thunder mine coal under extinction recycle (454{degrees}C+ recycle) condition; another goal was to investigate the effects of the combined processing of automobile shredder residue (auto-fluff) with coal and other organic waste materials. PB-04 employed a two-stage, back-mixed, slurry reactor system with an interstage V/L separator and an in-line fixed-bed hydrotreater. The HTI`s newly modified P/Fe catalyst was very effective for direct liquefaction and coprocessing of Black Thunder mine subbituminous coal with Hondo resid and auto-fluff; during `coal-only` liquefaction mode, over 93% maf coal conversion was obtained with about 90% residuum conversion and as high as 67% light distillate (C{sub 4}-975 F) yield, while during `coprocessing` mode of operation, distillate yields varied between 58 and 69%; the residuum conversions varied between 74 and 89% maf. Overall, it is concluded, based upon the yield data available from PB-04, that auto-effective as MSW plastics in improving coal hydroconversion process performance. Auto-fluff did not increase light distillate yields nor decrease light gas make and chemical hydrogen consumption in coal liquefaction, as was observed to occur with MSW plastics.

Probability of Liquefaction for Pit Disassembly and Conversion Facility (PDCF) Site, Savannah River Site  

Science Conference Proceedings (OSTI)

This report documents the probability of liquefaction (POL) for the Pit Disassembly and Conversion Facility (PDCF). The procedure for analysis of a critical layer of interest requires the following basic steps: (1) establish the probability of occurrence (POO) of ranges of 2.5 Hz bedrock motion based on a probabilistic seismic hazard assessment (PSHA); (2) define the critical layer that may be susceptible to liquefaction; (3) estimate distributions of cyclic stress ratio (CSR) (i.e., seismic demand) for the critical layer using site-specific soil properties corresponding to the bedrock motions; (4) estimate capacity of the critical layer based on site-specific cone penetration test (CPT) soundings and standard penetration test (SPT) blowcount data; and (5) sum the probability of liquefaction for each range of bedrock motion using empirical data correlating demand and capacity with liquefaction. The soil layer most susceptible to liquefaction is the critical layer. The critical layer is characterized by relatively low blowcount and low fines content and is established from soil layers below the water table. A key component for seismic demand is the establishment of the soil profile and it's uncertainty. The PDCF site is consistent with the 1997 SRS-specific model used to compute the site amplification database. Thus, previously derived site amplification functions reflecting the uncertainty in site properties and stratigraphy can be used to predict distributions of CSR given a specific earthquake magnitude and level of bedrock motion. The previously developed site amplification database reflects uncertainty in site response based on the large database of site shear-wave velocity profiles. Consequently, for each level of bedrock motion (from the PSHA) the site amplification database is used to establish the distribution of the expected CSR (demand) in the critical layer.

Surface modified coals for enhanced catalyst dispersion and liquefaction  

SciTech Connect

The aim of the study is to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants and catalysts on to the coal. During this reporting period, zeta potential measurements were conducted to assess the surface charge on the raw, pretreated and catalyzed coal samples. The surface area, transmission spectroscopy and luminescence intensity of the raw coal and pretreated coal samples were also determined to assess the quality of the coal surface. Across a broad range of pH values, the raw coal had an overall negative charge. Coal treated with anionic surfactant SDS maintained an overall net negative surface negative charge. The interaction between the coal and cationic surfactant DDAB caused the opposite effect resulting in a more positive coal surface charge. Although one would have expected little or no effect of the neutral surfactant Triton X-100, there appears to be some difference in the results of the raw coal and the coal treated with Triton X-100. The authors believe that the Triton not only binds to the nonpolar sites but also has a strong affinity for the polar sites through electrostatic bonding and interaction between the hydrophobic tails. The addition of molybdenum to coal pretreated with DDAB caused a reduction in the positive charge of the coal surface probably due to possible ionic interaction between the coal surface, the surfactant and the catalyst. The adsorption isotherm of the coal was characteristic of isotherms for porous samples and the surface area of the coal increased from 30 m{sup 2}/g to 77 m{sup 2}/g when washed with deionized water. This suggests coal washing may be one method of increasing the surface area for surfactant adsorption. Although the transmission measurements provided valuable information about the coal it resulted in little information on the amount of adsorbed Triton. However, the maximum solid-liquid ratio for optimum surfactant loading of Triton X-100 was determined via the UV-Vis spectrophotometer. The luminescence intensity measurements showed that the coal and surfactants luminescence weakly. No statistically significant influence was observed from the actions of the surfactants or surfactant-molybdenum catalyst. Qualitative inspection however, showed that SDS might effectively coat coal surfaces and influence catalyst dispersion. Also, catalysts appeared to be better distributed among coal particles and in finer clusters when DDAB and Triton surfactants were used.

Evaluation of coal minerals and metal residues as coal-liquefaction catalysts. Final report  

DOE Green Energy (OSTI)

The catalytic activity of various minerals, metallic wastes, and transition metals was investigated in the liquefaction of various coals. The effects of coal type, process variables, coal cleaning, catalyst addition mode, solvent quality, and solvent modification on coal conversion and oil production were also studied. Coal conversion and oil production improved significantly by the addition of pyrite, reduced pyrite, speculite, red mud, flue dust, zinc sulfide, and various transition metal compounds. Impregnation and molecular dispersion of iron gave higher oil production than particulate incorporation of iron. However, the mode of molybdenum addition was inconsequential. Oil production increased considerably both by adding a stoichiometric mixture of iron oxide and pyrite and by simultaneous impregnation of coal with iron and molybdenum. Hydrogenation activity of disposable catalysts decreased sharply in the presence of nitrogen compounds. The removal of heteroatoms from process solvent improved thermal as well as catalytic coal liquefaction. The improvement in oil production was very dramatic with a catalyst.

The testing program described in this report was carried out to study the liquefaction behavior of a clean, uniform, medium sand. Horizontal beds of this sand, 42 inches by 90 inches by 4 inches were prepared by pluviation with a special sand spreader, saturated, and tested in a shaking table system designed for this program, which applied a horizontal cyclic shear stress to the specimens. Specimen size was selected to reduce boundary effects as much as possible. Values of pore pressures and shear strains developed during the tests are presented for sand specimens at relative densities of 54, 68, 82, and 90 percent, and the results interpreted to determine the values of the stress ratio causing liquefaction at the various relative densities.

Mild coal pretreatment to improve liquefaction reactivity. Quarterly technical progress report, June--August 1991  

SciTech Connect

This report describes work completed during the fourth quarter of a three year project to study the effects of mild chemical pretreatment on coal dissolution reactivity during low severity liquefaction or coal/oil coprocessing. The overall objective of this research is to elucidate changes in the chemical and physical structure of coal by pretreating with methanol or other simple organic solvent and a trace amount of hydrochloric acid and measure the influence of these changes on coal dissolution reactivity. This work is part of a larger effort to develop a new coal liquefaction or coal/oil coprocessing scheme consisting of three main process steps: (1) mile pretreatment of the feed coal to enhance dissolution reactivity and dry the coal, (2) low severity thermal dissolution of the pretreated coal to obtain a very reactive coal-derived residual material amenable to upgrading, and (3) catalytic upgrading of the residual products to distillate liquids.

Page Jackson solar school, Charles Town, West Virginia. Final technical report  

DOE Green Energy (OSTI)

The Page Jackson Elementary School in Charles Town, West Virginia, uses a solar energy system to provide space heating and cooling for a 52,600 sq. ft. school building. A total of 11,215 sq. ft. of PPG Industries, Inc., double-glazed, flat plate collectors (facing south at a 45/sup 0/ tilt from the horizontal) are used in conjunction with glass mirrored reflectors facing north at a 38/sup 0/ tilt from the horizontal) to collect the available solar energy. The solar energy system at Page Jackson is of the drainback type. Space heating for the school is provided by circulating warm water from the storage tanks through five air handling units (AHU's). Space cooling to the building is provided by a 100 ton Trane packaged absorption water chiller when sufficiently hot solar water is available. The solar energy system began operation late in the summer of 1977. In general, the solar energy systemand controls appears to be in good working order. The performance of the system is particularly good; in fact, much better than most. Because the refurbished collector array is now operating at near design conditions, it is anticipated that the system will begin to contribute substantially (as originally intended) to the building load. In order to ensure that the system is operating as designed while in the space cooling mode, it is recommended that the solar cooling subsystem be tested for proper operation and performance during the warmer summer months.

An investigation of the role of water on retrograde/condensation reactions and enhanced liquefaction yields  

SciTech Connect

Changes in coal structure that may occur during coal drying will be measured in order to determine the effects of coal drying on its reactivity toward liquefaction. Different methods for coal drying will be investigated to determine if drying can be accomplished without destroying coal reactivity toward liquefaction, thereby making coal drying a relatively economical and efficient method for coal pretreatment. Coal drying methods will include conventional thermal drying, microwave drying and chemical drying at low temperature. State-of-the-art solid-state nuclear magnetic resonance (NMR) techniques using combined rotation and multiple pulse spectroscopy (CRAMPS) and cross polarization with magic-angle spinning (CP/MAS) will be employed: (1) to measures changes in coal structure brought about by the different methods of drying and by low temperature oxidation, and (2) to obtain direct measurements of changes in the aromatic hydrogen-to-carbon ratio of the solid/semisolid material formed or remaining during pretreatment and the initial stages of liquefaction. The objectives for this quarter were to begin coal drying experiments using thermal, microwave, and chemical methods, and to begin coal liquefaction experiments on the dried coals. Three additional coal samples have been acquired. These are a Black Thunder Mine coal acquired from Arco Coal Co, and a Texas subC and Illinois No. 6 hvC acquired from the DOE coal sample bank at Penn State. The samples are listed as DECS-1 and DECS-2, respectively in the PSU sample bank. The ultimate and proximate analyses for all the samples are given in Table 1. Work on each of the subtasks is described in separate paragraphs.

A characterization and evaluation of coal liquefaction process streams. Quarterly technical progress report, April 1--June 30, 1995  

Science Conference Proceedings (OSTI)

The objectives of this project are to support the DOE direct coal liquefaction process development program and to improve the useful application of analytical chemistry to direct coal liquefaction process development. Independent analyses by well-established methods will be obtained of samples produced in direct coal liquefaction processes under evaluation by DOE. Additionally, analytical instruments and techniques which are currently underutilized for the purpose of examining coal-derived samples will be evaluated. The data obtained from this study will be used to help guide current process development and to develop an improved data base on coal and coal liquids properties. A sample bank will be established and maintained for use in this project and will be available for use by other researchers. The reactivity of the non-distillable resids toward hydrocracking at liquefaction conditions (i.e., resid reactivity) will be examined. From the literature and data experimentally obtained, a mathematical kinetic model of resid conversion will be constructed. It is anticipated that such a model will provide insights useful for improving process performance and thus the economics of direct coal liquefaction. The paper describes activities carried out this quarter. 11 refs., 21 figs., 17 tabs.

Under subcontract from CONSOL Inc. (US DOE Contract No. DE-AC22-89PC89883), IIT Research Institute, National Institute for Petroleum and Energy Research applied a suite of petroleum inspection tests to two direct coal liquefactions net product oils produced in two direct coal liquefaction processing runs. Two technical reports, authored by NIPER, are presented here. The following assessment briefly describes the two coal liquefaction runs and highlights the major findings of the project. It generally is concluded that the methods used in these studies can help define the value of liquefaction products and the requirements for further processing. The application of these methods adds substantially to our understanding of the coal liquefaction process and the chemistry of coal-derived materials. These results will be incorporated by CONSOL into a general overview of the application of novel analytical techniques to coal-derived materials at the conclusion of this contract.

Coal liquefaction process wherein jet fuel, diesel fuel and/or ASTM No. 2 fuel oil is recovered

An improved process for the liquefaction of coal and similar solid carbonaceous materials wherein a hydrogen donor solvent or diluent derived from the solid carbonaceous material is used to form a slurry of the solid carbonaceous material and wherein the naphthenic components from the solvent or diluent fraction are separated and used as jet fuel components. The extraction increases the relative concentration of hydroaromatic (hydrogen donor) components and as a result reduces the gas yield during liquefaction and decreases hydrogen consumption during said liquefaction. The hydrogenation severity can be controlled to increase the yield of naphthenic components and hence the yield of jet fuel and in a preferred embodiment jet fuel yield is maximized while at the same time maintaining solvent balance.

Catalytic hydrotreating of biomass liquefaction products to produce hydrocarbon fuels: Interim report  

DOE Green Energy (OSTI)

Research catalytic hydrotreatment of biomass liquefaction products to a gasoline has been technically demonstrated in a bench-scale continuous processing unit. This report describes the development of the chemistry needed for hydrotreatment of both high pressure and pyrolyzate biomass liquefaction products and outlines the important processing knowledge gained by the research. Catalyst identity is important in hydrotreatment of phenolics. Hydrogenation catalysts such as palladium, copper chromite, cobalt and nickel show activity with nickel being the most active. Major products include benzene, cyclohexane, and cyclohexanone. The hydrotreating catalysts cobalt-molybdenum, nickel-molybdenum and nickel-tungsten exhibit some activity when added to the reactor in the oxide form and show a great specificity for hydrodeoxygenation of phenol without saturation of the benzene product. The sulfide form of these catalysts is much more active than the oxide form and, in the case of the cobalt-molybdenum, much of the specificity for hydrodeoxygenation is retained. Substitution on the phenolic ring has only marginal effects on the hydrotreating reaction. However, the methoxy (OCH/sub 3/) substituent on the phenol ring is thermally unstable relative to other phenolics tested. The pyrolysis products dominate the product distribution when cobalt-molybdenum is used as the hydrotreating catalyst for methoxyphenol. The product from catalytic hydrotreatment of high-pressure biomass liquefaction products confirms the model compounds studies. Catalytic processing at 350 to 400/sup 0/C and 2000 psig with the sulfided cobalt-molybdenum or nickel-molybdenum catalyst produced a gasoline-like product composed of cyclic and aromatic compounds. Oxygen contents in products were in the range of 0 to 0.7 wt % and hydrogen to carbon atomic ratios ranged from 1.5 to 2.0. 46 refs., 10 figs., 21 tabs.

Cooperative research in coal liquefaction. Final report, May 1, 1991--April 30, 1992  

Science Conference Proceedings (OSTI)

Extensive research continued on catalysts based on novel anion-treated (mainly sulfated) oxides and oxyhydroxides of iron [Fe{sub x}O{sub y}/SO{sub 4}]. In addition, sulfated oxides of tin as well as molybdenum promoted iron oxides were used. Incorporation of small amounts of sulfate, molybdate, or tungstate anions by wet precipitation/impregnation methods was found to increase the surface acidic character of iron oxides; more importantly, it reduced the grain sizes significantly with corresponding increases in specific surface areas. These anion-treated iron and tin oxides were more active for direct coal liquefaction and coal-heavy oil coprocessing than their untreated counterparts. With these catalyst systems, higher conversion levels are obtained as compared to the soluble precursors of iron and molybdenum at the same catalyst metalloading (3500 ppm iron and 50 ppm molybdenum with respect to coal). Sulfated iron oxides and oxyhydroxides were equally active as coal liquefaction catalysts. The sulfate, molybdate, and tungstate anions were found to have similar promotional effects on the properties and activities of iron oxides. One step in the synthesis of anion-treated iron and tin oxides is precipitation as hydroxides using either urea or ammonium hydroxide. The catalysts prepared using urea as a precipitation agent were more reproducible than those using ammonium, hydroxide in terms of activities and properties. These catalysts/catalyst precursors were characterized by several techniques to determine their physical (size and structure related) and chemical (acidity) properties. Sulfated and molybdated iron oxides were found to have grain sizes as small as 10-20 nm. An attempt was made to correlate the physicochemical properties of these catalysts with their activity for coal liquefaction.

Direct liquefaction proof-of-concept program: Bench Run 05 (227-97). Final report  

DOE Green Energy (OSTI)

This report presents the results Bench Run PB-05, conducted under the DOE Proof of Concept - Bench Option Program in direct coal liquefaction at Hydrocarbon Technologies, Inc. in Lawrenceville, New Jersey. Bench Run PB-05 was the fifth of the nine runs planned in the POC Bench Option Contract between the U.S. DOE and included the evaluation of the effect of using dispersed slurry catalyst in direct liquefaction of a high volatile bituminous Illinois No. 6 coal and in combined coprocessing of coal with organic wastes, such as heavy petroleum resid, MSW plastics, and auto-shredder residue. PB-05 employed a two-stage, back-mixed, slurry reactor system with an interstage V/L separator and an in-line fixed-bed hydrotreater. Coprocessing of waste plastics with Illinois No. 6 coal did not result in the improvement observed earlier with a subbituminous coal. In particular, decreases in light gas yield and hydrogen consumption were not observed with Illinois No. 6 coal as they were with Black Thunder Mine coal. The higher thermal severity during PB-05 is a possible reason for this discrepancy, plastics being more sensitive to temperatures (cracking) than either coal or heavy resid. The ASR material was poorer than MSW plastics in terms of increasing conversions and yields. HTI`s new dispersed catalyst formulation, containing phosphorus-promoted iron gel, was highly effective for the direct liquefaction of Illinois No. 6 coal under the reaction conditions employed; over 95% coal conversion was obtained, along with over 85% residuum conversion and over 73% distillate yields.

Effect of coal rank and process conditions on temperature distribution in a liquefaction reactor  

SciTech Connect

The temperature distribution in a liquefaction reactor in the integrated TSL process is studied. The effects of gas and slurry superficial velocities, process solvent characteristics, reactor length, and catalyst sulfiding agent on the exotherm and temperature difference in the reactor are studied. A substantial temperature difference is observed with subbituminous coal as compared with bituminous coal, at comparable reactor conditions. Some of the factors that are believed to have contributed to the large exotherm and temperature difference in the reactor are slow kinetics and high reaction heat for subbituminous coal conversion and pyrrhotite catalysis.

An automated apparatus for the solvent separation of a coal liquefaction product stream that operates continuously and unattended and eliminates potential errors resulting from subjectivity and the aging of the sample during analysis. In use of the apparatus, metered amounts of one or more solvents are passed sequentially through a filter containing the sample under the direction of a microprocessor control means. The mixture in the filter is agitated by means of ultrasonic cavitation for a timed period and the filtrate is collected. The filtrate of each solvent extraction is collected individually and the residue on the filter element is collected to complete the extraction process.

Effects of low-temperature catalytic pretreatments on coal structure and reactivity in liquefaction. Technical progress report, December 1992--March 1993  

SciTech Connect

This work is a fundamental study of catalytic pretreatments as a potential preconversion step to low-severity liquefaction. The ultimate goal of this work is to provide the basis for the design of an improved liquefaction process and to facilitate our understanding of those processes that occur when coals are initially dissolved. The main objectives of this project are to study the effects of low-temperature pretreatments on coal structure and their impacts on the subsequent liquefaction. The effects of pretreatment temperatures, catalyst type, coal rank and influence of solvent will be examined. We have made significant progress in the following four aspects during this quarterly period: (1) influence of drying and oxidation of coal on the conversion and product distribution in catalytic liquefaction of Wyodak subbituminous coal using a dispersed catalyst; (2) spectroscopic characterization of dried and oxidized Wyodak coal and the insoluble residues from catalytic and thermal liquefaction; (3) the structural alteration of low-rank coal in low-severity liquefaction with the emphasis on the oxygen-containing functional groups; and (4) effects of solvents and catalyst dispersion methods in temperature-programmed and non-programmed liquefaction of three low-rank coals.

Additive effect of waste tire on the hydrogenolysis reaction of coal liquefaction residue  

Science Conference Proceedings (OSTI)

A numerous amount of waste tire is landfilled or dumped all over the world, which causes environmental problems, such as destruction of natural places and the risk of fires. On the other hand, the coal liquefaction residue (CLR) is produced in 30% yield through the process supporting unit (PSU) of the NEDOL coal liquefaction process. Therefore, the investigation on an effective method for utilization of waste tire and CLR is required. In this study, the simultaneous hydrogenolysis of CLR and pulverized waste tire was carried out by using tetralin. The yields in the simultaneous hydrogenolysis were compared with algebraic sum of the yields of the individual hydrogenolyses of waste tire alone and coal alone. In the simultaneous hydrogenolysis, the synergistic effects to upgrading, such as an increase in the yield of the oil constituent and a decrease in the yield of the asphaltene constituent, occurred because of the stabilization of asphaltenic radicals from CLR with aliphatic radicals from tire. The decrease in asphaltene yield in the simultaneous hydrogenolysis was pronounced with the increase in the tire:CLR ratio because the solvent effects of liquefied tire, such as stabilization of radicals, hydrogen shuttling, and heat transfer, were enhanced. Accordingly, it is estimated that the simultaneous hydrogenolysis of CLR and waste tire is an effective method for processing both materials. 15 refs., 3 figs., 2 tabs.

DOE Patents (OSTI)

An apparatus and method for producing liquefied natural gas. A liquefaction plant may be coupled to a source of unpurified natural gas, such as a natural gas pipeline at a pressure letdown station. A portion of the gas is drawn off and split into a process stream and a cooling stream. The cooling stream passes through a turbo expander creating work output. A compressor is driven by the work output and compresses the process stream. The compressed process stream is cooled, such as by the expanded cooling stream. The cooled, compressed process stream is divided into first and second portions with the first portion being expanded to liquefy the natural gas. A gas-liquid separator separates the vapor from the liquid natural gas. The second portion of the cooled, compressed process stream is also expanded and used to cool the compressed process stream. Additional features and techniques may be integrated with the liquefaction process including a water clean-up cycle and a carbon dioxide (CO.sub.2) clean-up cycle.

Impact of hydrogen partial pressure on coal liquefaction. Final technical report  

DOE Green Energy (OSTI)

This program was conducted to determine the effects of hydrogen partial pressure on the SRC-I direct coal liquefaction process and SRC-I Demonstration Plant design. A native solvent was produced in quantity and slurried with Kentucky number 9 Mulford coal in a series of coal liquefaction runs under varying hydrogen gas rates, temperatures, residence times, and hydrogen partial pressures. The results showed that hydrogen partial pressure significantly affected product distribution; the magnitude of the effect was comparable to changes in temperature and residence time. Also, the impact of hydrogen partial pressure was enhanced by increases in both temperature and residence time. Operating at low hydrogen partial pressure did not show any apparent advantage; it reduced coal conversion, reduced oil yield, and had a detrimental effect on the yield distribution of other products. An increase in hydrogen partial pressure had the following effects: increased coal conversion; increased conversion of asphaltenes and preasphaltenes to lighter products; significantly increased the oil yield; increased light gas yields; decreased sulfur content in the SRC; increased hydrogen content of the recycle solvent; and increased hydrogen consumption. This study strongly suggests that further studies should be conducted to optimize the effects of hydrogen partial pressure on the process, both within and, preferably, beyond the constraints of the current basic SRC-I design, considering the major impact of this variable on the process. 10 references, 37 figures, 10 tables.

Novel experimental studies for coal liquefaction: Quarterly progress report, April 1, 1987 to June 30, 1987  

SciTech Connect

In Task 1 of this project, the use of a slurry reactor for indirect coal liquefaction is being studied. Work is being done using three indirect liquefaction routes involving synthesis gas - the Fisher-Tropsch reaction, the one-step conversion to methanol, and the two-step conversion to methanol via methyl formate. Experimental work and data analysis for the two-step methanol synthesis in a single slurry reactor were continued during the quarter. Experimental work included the effect of the H/sub 2//CO ratio on the simultaneous reactions and measurements of the solubility of hydrogen and CO in methanol and methyl formate. Reaction rates obtained experimentally for the simultaneous system were compared with rates calculated from the individual reactions. The two-step methanol synthesis involves two reactions, and one of the reactants in each reaction is a gas. The carbonylation of methanol requires CO and the hydrogenolysis of methyl formate requires H/sub 2/. The ratio of H/sub 2/ to CO is therefore a very important operating parameter, affecting the relative rates of the two reactions and the total methanol production rate. It may also affect the selectivity of the two reations. Two runs were made, one at a temperature of 121/sup 0/C and the other at 140/sup 0/C. All reaction conditions were constant except for the H/sub 2//CO ratio. The experimental procedure was the same as described previously. 61 refs.

Why Sequence Great Salt Lake?  

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

Great Salt Lake? Great Salt Lake? On average, the Great Salt Lake is four times saltier than the ocean and also has heavy metals, high concentrations of sulfur and petroleum seeps. In spite of all this, the lake is the saltiest body of water to support life. The lake hosts brine shrimp, algae and a diverse array of microbes, not to mention the roughly 5 million birds that migrate there annually. The secret to these microbes' ability to survive under such harsh conditions might be revealed in their genes. Researchers expect the genetic data will provide insight into how the microorganisms tolerate pollutants such as sulfur and detoxify pollutants such as sulfur and heavy metals like mercury. The information could then be used to develop bioremediation techniques. Researchers also expect that sequencing microorganisms sampled

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

SciTech Connect

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

Effects of low-temperature catalytic pretreatments on coal structure and reactivity in liquefaction. Technical progress report, August 1992--July 1992  

Science Conference Proceedings (OSTI)

Low-temperature catalytic pretreatment is a promising approach to the development of an improved liquefaction process- This work is a fundamental study on effects of pretreatments on coal structure and reactivity in liquefaction. The main objectives of this project are to study the coal structural changes induced by low-temperature catalytic and thermal pretreatments by using spectroscopic techniques; and to clarify the pretreatment-induced changes in reactivity or convertibility of coals in the subsequent liquefaction. This report describes the recent progress of our work. Substantial progress has been made in the spectroscopic characterization of structure and pretreatment-liquefaction reactions of a Montana subbituminous Coal (DECS-9), and thermochemical analysis of three mw and reacted bituminous coals. Temperature programmed liquefaction has been performed on three low-rank coals both in the presence and absence of dispersed molybdenum sulfide catalyst. We also performed a detailed study of the effects of mild thermal pretreatment -- drying in air and in vacuum -- on thermal and catalytic liquefaction of a Wyodak subbituminous coal. Important information on structure and structure transformation during thermal pretreatment and liquefaction reactions of low-rank coals has been derived by applying solid-state CPMAS {sup 13}C NMR and flash pyrolysis-GC-MS (Py-GC-MS) for characterization of the macromolecular network of a Montana subbituminous coal and its residues from temperature-programmed and nonprogrammed liquefaction (TPL and N-PL) at final temperatures ranging from 300 to 425{degree}C in H-donor and non-donor solvents. The results revealed that this coal contains significant quantities of oxygen-bearing structures, corresponding to about 18 O-bound C per 100 C atoms and one O-bound C per every 5 to 6 aromatic C.

Process for coal liquefaction by separation of entrained gases from slurry exiting staged dissolvers  

SciTech Connect

There is described an improved liquefaction process by which coal is converted to a low ash and low sulfur carbonaceous material that can be used as a fuel in an environmentally acceptable manner without costly gas scrubbing equipment. In the process, coal is slurried with a solvent, passed through a preheater and at least two dissolvers in series in the presence of hydrogen-rich gases at elevated temperatures and pressures. Solids, including mineral ash and unconverted coal macerals are separated from the condensed dissolver effluent. In accordance with the improved process, fresh hydrogen is fed to each dissolver and the entrained gas from each dissolver is separated from the slurry phase and removed from the reactor system before the condensed phase is passed to the next dissolver in the series. In accordance with another process, the feeds to the dissolvers are such that the top of each downstream dissolver is used as a gas-liquid separator.

To this end, one phase of this research has investigated the cleavage of carbon-heteroatom bonds involving sulfur, oxygen, nitrogen and halogen by subvalent transition-metal complexes. A second phase of the study has assessed the capability of the same transition-metal complexes or of organoaluminum Lewis acids to catalyze the cleavage of carbon-hydrogen bonds in aromatics and hence to promote hydrogen shuttling.

Design of generic coal conversion facilities: Indirect coal liquefaction, Fischer-Tropsch synthesis  

SciTech Connect

A comprehensive review of Fischer-Tropsch (F-T) technology, including fixed, fluidized, and bubble column reactors, was undertaken in order to develop an information base before initiating the design of the Fischer-Tropsch indirect liquefaction PDU as a part of the Generic Coal Conversion Facilities to be built at the Pittsburgh Energy Technology Center (PETC). The pilot plant will include a fixed bed and slurry bubble column reactor for the F-T mode of operation. The review encompasses current status of both these technologies, their key variables, catalyst development, future directions, and potential improvement areas. However, more emphasis has been placed on the slurry bubble column reactor since this route is likely to be the preferred technology for commercialization, offering process advantages and, therefore, better economics than fixed and fluidized bed approaches.

Environmental and Economical Evaluation of Integrating NGL Extraction and LNG Liquefaction Technology in Iran LNG Project  

E-Print Network (OSTI)

The combination of changing global markets for natural gas liquids (NGL) with the simultaneous increase in global demand for liquefied natural gas (LNG) has stimulated an interest in the integration of NGL recovery technology with LNG liquefaction technologies. Historically, the removal of “heavy” or high-freezing-point hydrocarbons from the feed to LNG plants has been characterized as “gas conditioning” and achieved using one or more distillation columns. While some attempts to provide reflux to the distillation columns marginally enhanced NGL recovery, little emphasis was placed on maximizing NGL recovery as a product from the LNG process. As such, the integration of the two processes was not a priority. Integrating state-of-the art NGL recovery technology within the CoP LNGSM Process1, formerly the Phillips Optimized Cascade LNG Process, results in a significant reduction in the specific power required to produce LNG, while maximizing NGL recovery. This corresponds to a production increase in both LNG and NGL for comparable compression schemes as compared to stand-alone LNG liquefaction and NGL extraction facilities. In addition, there are potential enhancements to the overall facility availability and project economics and environmental impacts using the integrated concept. This integrated concept has been applied to three ongoing international NGL/LNG projects using the CoP LNG Process in Iran LNG project. In this respect, simulation has been performed in THERMOFLEX software. Moreover, thermo economic analysis has been applied for economic and thermodynamic analysis of base and integrated cases through computer code has been provided here. Finally, the base and integrated case have been evaluated and comprised in view of thermodynamics, economics and environmental impacts.

Surface modified coals for enhanced catalyst dispersion and liquefaction. Semiannual progress report, September 1, 1995--February 29, 1996  

SciTech Connect

The aim of this work is to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants onto coal. The application of surfactants to coal beneficiation and coal-water slurry preparation is well known. However, the effects of surfactants on catalyst loading and dispersion prior to coal liquefaction have not been investigated. The current work is focused on the influence of the cationic surfactant dodecyl dimethyl ethyl ammonium bromide (DDAB) and sodium dodecyl sulfate (SDS, anionic) on the surface properties of a bituminous coal and its molybdenum uptake from solution. The results show that DDAB created positively charged sites on the coal and increased molybdenum loading compared to the original coal. In contrast, SDS rendered the coal surface negative and reduced molybdenum uptake. The results show that efficient loading of molybdenum catalyst onto coal can be achieved by pretreatment of the coal with dodecyl dimethyl ethyl ammonium bromide.

Development of an extruder-feeder biomass direct liquefaction process. Volume 2, Parts 4--8: Final report  

DOE Green Energy (OSTI)

As an abundant, renewable, domestic energy resource, biomass could help the United States reduce its dependence on imported oil. Biomass is the only renewable energy technology capable of addressing the national need for liquid transportation fuels. Thus, there is an incentive to develop economic conversion processes for converting biomass, including wood, into liquid fuels. Through research sponsored by the US DOE`s Biomass Thermochemical Conversion Program, the University of Arizona has developed a unique biomass direct liquefaction system. The system features a modified single-screw extruder capable of pumping solid slurries containing as high as 60 wt% wood flour in wood oil derived vacuum bottoms at pressures up to 3000 psi. The extruder-feeder has been integrated with a unique reactor by the University to form a system which offers potential for improving high pressure biomass direct liquefaction technology. The extruder-feeder acts simultaneously as both a feed preheater and a pumping device for injecting wood slurries into a high pressure reactor in the biomass liquefaction process. An experimental facility was constructed and following shakedown operations, wood crude oil was produced by mid-1985. By July 1988, a total of 57 experimental continuous biomass liquefaction runs were made using White Birch wood feedstock. Good operability was achieved at slurry feed rates up to 30 lb/hr, reactor pressures from 800 to 3000 psi and temperatures from 350{degree}C to 430{degree}C under conditions covering a range of carbon monoxide feed rates and sodium carbonate catalyst addition. Crude wood oils containing as little as 6--10 wt% residual oxygen were produced. 38 refs., 82 figs., 26 tabs.

Liquefaction process wherein solvents derived from the material liquefied and containing increased concentrations of donor species are employed  

DOE Patents (OSTI)

An improved process for the liquefaction of solid carbonaceous materials wherein a solvent or diluent derived from the solid carbonaceous material being liquefied is used to form a slurry of the solid carbonaceous material and wherein the solvent or diluent comprises from about 65 to about 85 wt. % hydroaromatic components. The solvent is prepared by first separating a solvent or diluent distillate fraction from the liquefaction product, subjecting this distillate fraction to hydrogenation and then extracting the naphthenic components from the hydrogenated product. The extracted naphthenic components are then dehydrogenated and hydrotreated to produce additional hydroaromatic components. These components are combined with the solvent or diluent distillate fraction. The solvent may also contain hydroaromatic constituents prepared by extracting naphthenic components from a heavy naphtha, dehydrogenating the same and then hydrotreating the dehydrogenated product. When the amount of solvent produced in this manner exceeds that required for steady state operation of the liquefaction process a portion of the solvent or diluent distillated fraction will be withdrawn as product.

Advanced liquefaction using coal swelling and catalyst dispersion techniques. Volume 2, appendices. Final technical report, October 1, 1991--September 30, 1994  

Science Conference Proceedings (OSTI)

Liquefaction experiments were undertaken using subbituminous Black Thunder mine coal to observe the effects of aqueous SO{sub 2} coal beneficiation and the introduction of various coal swelling solvents and catalyst precursors. Aqueous SO{sub 2} beneficiation of Black Thunder coal removed alkali metals and alkaline earth metals, increased the sulfur content and increased the catalytic liquefaction conversion to THF solubles compared to untreated Black Thunder coal. The liquefaction solvent had varying effects on coal conversion, depending upon the type of solvent added. The hydrogen donor solvent, dihydroanthracene, was most effective, while a coal-derived Wilsonville solvent promoted more coal conversion than did relatively inert 1-methylnaphthalene. Swelling of coal with hydrogen bonding solvents tetrahydrofuran (THF), isopropanol, and methanol, prior to reaction resulted in increased noncatalytic conversion of both untreated and SO{sub 2} treated Black Thunder coals, while dimethylsulfoxide (DMSO), which was absorbed more into the coal than any other swelling solvent, was detrimental to coal conversion. Swelling of SO{sub 2} treated coal before liquefaction resulted in the highest coal conversions; however, the untreated coal showed the most improvements in catalytic reactions when swelled in either THF, isopropanol, or methanol prior to liquefaction. The aprotic solvent DMSO was detrimental to coal conversion.

Preconversion processing of bituminous coals: New directions to improved direct catalytic coal liquefaction. Quarterly report, July 1, 1992--September 30, 1992  

SciTech Connect

Soaking coal in coal liquids at 300-400{degrees}C (high-tenperature soaking) has been studied for coal dissolution prior to liquefaction in the previous task. Two high-volatile bituminous coals, Illinois No. 6 and Pittsburgh No. 8, were examined in three different coal liquids. The high-temperature soaking was effective to solubilize more than 70 wt% cf these coals. The mechanism of disintegration of coal by the high-temperature soaking was investigated under various soaking conditions. The products was also analyzed with solvent swelling. These results were rationalized that coal is solubilized primarily by physical disintegration. The derived mechanism was consistent with the new concept of coal structure: A significant portion of coal is physically associated, not three-dimensionally cross-linked. Radically-induced scission reactions were proposed to prorate breakage of coal moleculs by the combination of the high-temperature soaking before liquefaction. In this term, the effect of radical initiators were investigated under the conditions of the high-temperature soaking and liquefaction. Illinois No. 6 coal and a coal liquid derived from the same coal were used. The first section reports the effect of radical initiators on coal disintegration, and the second section reports the effect of a radical initiator on coal liquefaction. Radical initiators had a positive effect on disintegration. However, the effect was highly temperature-dependent and had a negative effect on liquefaction at high tenperatures.

Coal liquefaction process utilizing coal/CO.sub.2 slurry feedstream  

DOE Patents (OSTI)

A coal hydrogenation and liquefaction process in which particulate coal feed is pressurized to an intermediate pressure of at least 500 psig and slurried with CO.sub.2 liquid to provide a flowable coal/CO.sub.2 slurry feedstream, which is further pressurized to at least 1000 psig and fed into a catalytic reactor. The coal particle size is 50-375 mesh (U.S. Sieve Series) and provides 50-80 W % coal in the coal/CO.sub.2 slurry feedstream. Catalytic reaction conditions are maintained at 650.degree.-850.degree. F. temperature, 1000-4000 psig hydrogen partial pressure and coal feed rate of 10-100 lb coal/hr ft.sup.3 reactor volume to produce hydrocarbon gas and liquid products. The hydrogen and CO.sub.2 are recovered from the reactor effluent gaseous fraction, hydrogen is recycled to the catalytic reactor, and CO.sub.2 is liquefied and recycled to the coal slurrying step. If desired, two catalytic reaction stages close coupled together in series relation can be used. The process advantageously minimizes the recycle and processing of excess hydrocarbon liquid previously needed for slurrying the coal feed to the reactor(s).

Science Conference Proceedings (OSTI)

This is the eleventh Quarterly Technical Progress Report under DOE Contract DE-AC22-89PC89883. Major topics reported are: (1) The results of a study designed to determine the effects of the conditions employed at the Wilsonville slurry preheater vessel on coal conversion is described. (2) Stable carbon isotope ratios were determined and used to source the carbon of three product samples from Period 49 of UOP bench-scale coprocessing Run 37. The results from this coprocessing run agree with the general trends observed in other coprocessing runs that we have studied. (3) Microautoclave tests and chemical analyses were performed to ``calibrate`` the reactivity of the standard coal used for determining donor solvent quality of process oils in this contract. (4) Several aspects of Wilsonville Close-Coupled Integrated Two-Stage Liquefaction (CC-ITSL) resid conversion kinetics were investigated; results are presented. Error limits associated with calculations of deactivation rate constants previously reported for Runs 258 and 261 are revised and discussed. A new procedure is described that relates the conversions of 850{degrees}F{sup +} , 1050{degrees}F{sup +}, and 850 {times} 1050{degrees}F material. Resid conversions and kinetic constants previously reported for Run 260 were incorrect; corrected data and discussion are found in Appendix I of this report.

Surface modified coals for enhanced catalyst dispersion and liquefaction. Quarterly report, 1996  

SciTech Connect

The aim of this work is to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants onto coal. The application of surfactants to coal beneficiation and coal-water slurry preparation is well known. However, the effects of surfactants on catalyst loading and dispersion prior to coal conversion processes have not been investigated. The current work is focused on the influence of the cationic surfactant dodecyl dimethyl ethyl ammonium bromide (DDAB) and sodium dodecyl sulfate (SDS, anionic) on the surface properties of a bituminous coal and its molybdenum and iron uptake from solution. In the previous report, it was shown that molybdenum loading onto the coal was enhanced by preadsorption of DDAB. The optimum concentration of this surfactant for effective adsorption of molybdenum at the natural pH of the coal slurry has been determined to be in the 0.1 to 0.25 M range. Preadsorption of SDS onto the coal was found to increase the uptake of iron by the coal; iron loading increased with increase in the concentration of the catalyst precursor. This observation is attributed to the increase in the negative surface charge properties of the coal with increase in the concentration of the surfactant. The results of the study show that DDAB enhances the adsorption of molybdenum whereas SDS is more effective for iron loading onto Illinois No. 6 (DECS-24) coal.

Apparatus and process for the refrigeration, liquefaction and separation of gases with varying levels of purity  

DOE Patents (OSTI)

A process for the separation and liquefaction of component gasses from a pressurized mix gas stream is disclosed. The process involves cooling the pressurized mixed gas stream in a heat exchanger so as to condensing one or more of the gas components having the highest condensation point; separating the condensed components from the remaining mixed gas stream in a gas-liquid separator; cooling the separated condensed component stream by passing it through an expander; and passing the cooled component stream back through the heat exchanger such that the cooled component stream functions as the refrigerant for the heat exchanger. The cycle is then repeated for the remaining mixed gas stream so as to draw off the next component gas and further cool the remaining mixed gas stream. The process continues until all of the component gases are separated from the desired gas stream. The final gas stream is then passed through a final heat exchanger and expander. The expander decreases the pressure on the gas stream, thereby cooling the stream and causing a portion of the gas stream to liquify within a tank. The portion of the gas which is hot liquefied is passed back through each of the heat exchanges where it functions as a refrigerant.

Analysis and prevention of metallurgical failures at a major direct coal liquefaction pilot plant  

Science Conference Proceedings (OSTI)

The H-Coal Pilot Plant in Catlettsburg, KY was the largest-capacity direct coal liquefaction project operating in the United States. Since the start of operations, performance of its components was carefully monitored and occasional failures were examined and documented. The results of the examinations were used to develop remedial steps and improve the design of scale-up units. In this paper, the metallurgical aspects of the following incidents will be described: 1) stress corrosion cracking of martensitic stainless steel bolting on the waterside of a heat exchanger; 2) stress corrosion cracking of a superalloy seal ring; 3) brittle failure of a low alloy nut in a block valve body; 4) corrosion damage in the fractionator and side stripper; 5) erosion/corrosion of a coal liquid transfer line in the atmospheric fractionation area; 6) pitting corrosion in a deaerator carbon steel inlet pipe; 7) brittle failure of a martensitic stainless steel ball in a block valve handling coal liquids; and 8) cracking of cobalt-base alloy seat rings in block valve applications. In addition, remedial steps and preventive measures leading to successful performance after repair are briefly described.

Production and Optimization of Direct Coal Liquefaction derived Low Carbon-Footprint Transportation Fuels  

DOE Green Energy (OSTI)

This report summarizes works conducted under DOE Contract No. DE-FC26-05NT42448. The work scope was divided into two categories - (a) experimental program to pretreat and refine a coal derived syncrude sample to meet transportation fuels requirements; (b) system analysis of a commercial scale direct coal liquefaction facility. The coal syncrude was derived from a bituminous coal by Headwaters CTL, while the refining study was carried out under a subcontract to Axens North America. The system analysis included H{sub 2} production cost via six different options, conceptual process design, utilities requirements, CO{sub 2} emission and overall plant economy. As part of the system analysis, impact of various H{sub 2} production options was evaluated. For consistence the comparison was carried out using the DOE H2A model. However, assumptions in the model were updated using Headwaters database. Results of Tier 2 jet fuel specifications evaluation by the Fuels & Energy Branch, US Air Force Research Laboratory (AFRL/RZPF) located at Wright Patterson Air Force Base (Ohio) are also discussed in this report.

Two coals, a Texas subbituminous C and a Utah high volatile A bituminous, were used to examine the effects of solvent swelling and catalyst impregnation on liquefaction conversion behavior in temperature staged reactions for 30 minutes each at 275{degree} and 425{degree}C in H{sub 2} and 95:5 H{sub 2}:H{sub 2}S atmospheres. Methanol, pyridine, tetrahydrofuran, and tetrabutylammonium hydroxide were used as swelling agents. Molybdenum-based catalyst precursors were ammonium tetrathiomolybdate, molybdenum trisulfide, molybdenum hexacarbonyl, and bis(tricarbonylcyclopentadienyl-molybdenum). Ferrous sulfate and bis(dicarbonylcyclo-pentadienyliron) served as iron-based catalyst precursors. In addition, ion exchange was used for loading iron onto the subbituminous coal. For most experiments, liquefaction in H{sub 2}:H{sub 2}S was superior to that in H{sub 2}, regardless of the catalyst precursor. The benefit of the H{sub 2}S was greater for the subbituminous, presumably because of its higher iron content relative to the hvab coal. Tetrabutylammonium hydroxide was the only swelling agent to enhance conversion of the hvab coal significantly; it also caused a remarkable increase in conversion of the subbituminous coal. The combined application of solvent swelling and catalyst impregnation also improves liquefaction, mainly through increased oil yields from the hvab coal and increased asphaltenes from the subbituminous. A remarkable effect from use of ammonium tetrathiomolybdate as a catalyst precursor is substantial increase in pristane and phytane yields. Our findings suggest that these compounds are, at least in part, bound to the coal matrix.

Catalysts and process developments for two-stage liquefaction. Final technical report, October 1, 1989--September 30, 1992  

SciTech Connect

Research in this project centered upon developing and evaluating catalysts and process improvements for coal liquefaction in the two-stage, close-coupled catalytic process. The major results are summarized here and they are described in more detail under each Task. In tasks for coal pretreatment and beneficiation, it was shown for coal handling that drying of both lignite or subbituminous coals using warm air, vacuum oven or exposing to air for long time was detrimental to subsequent liquefaction. Both laboratory and bench-scale beneficiations indicated that in order to achieve increased liquefaction yield for Illinois No. 6 bituminous coal, size separation with in sink-float technique should be used. For subbituminous coal, the best beneficiation was aqueous SO{sub 2} treatment, which reduced mineral matter. In the case of lignite, the fines should be rejected prior to aqueous SO{sub 2} treatment and sink-float gravity separation. In liquefying coals with supported catalysts in both first and second stages, coal conversion was highest (93%) with Illinois No. 6 coal, which also had the highest total liquid yield of 80%, however, the product contained unacceptably high level of resid (30%). Both low rank coals gave lower conversion (85--87%) and liquid yields (57--59%), but lighter products (no resid). The analysis of spent first stage catalysts indicated significant sodium and calcium deposits causing severe deactivation. The second stage catalysts were in better condition showing high surface areas and low coke and metal deposits. The use of dispersed catalyst in the first stage would combat the severe deactivation.

Contaminant Monitoring Strategy for Henrys Lake, Idaho  

Science Conference Proceedings (OSTI)

Henrys Lake, located in southeastern Idaho, is a large, shallow lake (6,600 acres, {approx} 17.1 feet maximum depth) located at 6,472 feet elevation in Fremont Co., Idaho at the headwaters of the Henrys Fork of the Snake River. The upper watershed is comprised of high mountains of the Targhee National Forest and the lakeshore is surrounded by extensive flats and wetlands, which are mostly privately owned. The lake has been dammed since 1922, and the upper 12 feet of the lake waters are allocated for downriver use. Henrys Lake is a naturally productive lake supporting a nationally recognized ''Blue Ribbon'' trout fishery. There is concern that increasing housing development and cattle grazing may accelerate eutrophication and result in winter and early spring fish kills. There has not been a recent thorough assessment of lake water quality. However, the Department of Environmental Quality (DEQ) is currently conducting a study of water quality on Henrys Lake and tributary streams. Septic systems and lawn runoff from housing developments on the north, west, and southwest shores could potentially contribute to the nutrient enrichment of the lake. Many houses are on steep hillsides where runoff from lawns, driveways, etc. drain into wetland flats along the lake or directly into the lake. In addition, seepage from septic systems (drainfields) drain directly into the wetlands enter groundwater areas that seep into the lake. Cattle grazing along the lake margin, riparian areas, and uplands is likely accelerating erosion and nutrient enrichment. Also, cattle grazing along riparian areas likely adds to nutrient enrichment of the lake through subsurface flow and direct runoff. Stream bank and lakeshore erosion may also accelerate eutrophication by increasing the sedimentation of the lake. Approximately nine streams feed the lake (see map), but flows are often severely reduced or completely eliminated due to irrigation diversion. In addition, subsurface flows can occur as a result of severe cattle grazing along riparian areas and deltas. Groundwater and springs also feed the lake, and are likely critical for oxygen supply during winter stratification. During the winter of 1991, Henrys Lake experienced low dissolved oxygen levels resulting in large fish kills. It is thought that thick ice cover combined with an increase in nutrient loads created conditions resulting in poor water quality. The Idaho Department of Health and Welfare, DEQ is currently conducting a study to determine the water quality of Henrys Lake, the sources contributing to its deterioration, and potential remedial actions to correct problem areas.

Lake Ontario Maritime Cultural Landscape  

E-Print Network (OSTI)

The goal of the Lake Ontario Maritime Cultural Landscape project was to investigate the nature and distribution of archaeological sites along the northeast shoreline of Lake Ontario while examining the environmental, political, and cultural factors that influenced the position of these sites. The primary method of investigation was a combined archaeological and historical survey of the shoreline within seven 1-km square areas. The archaeological component of the survey covered both the terrestrial and submerged portions of the shore through marine remote sensing (side-scan sonar and magnetometer), diving surveys, pedestrian surveys, and informant interviews. A total of 39 sites and 51 isolated finds were identified or further analyzed as a result of this project. These sites ranged from the Middle Archaic period (ca. 5500-2500 B.C.) through the 19th century and included habitation, military, transportation, and recreational sites. Analysis of these findings was conducted at two scales: the individual survey area and Lake Ontario as a whole. By treating each survey area as a distinct landscape, it was possible to discuss how various cultures and groups used each space and to identify instances of both dynamism and continuity in the landscapes. Results of these analyses included the continuous occupation of several locations from pre-Contact times to the present, varying uses of the same environment in response to political and economic shifts, the formation of communities around transportation nodes, and recurring settlement patterns. The survey data was also combined to explore regional-scale trends that manifest themselves in the historical Lake Ontario littoral landscape including ephemeral landscapes, permeable boundaries, danger in the lake, and factors of change.

Direct liquefaction Proof-of-Concept facility. Final technical progress report  

DOE Green Energy (OSTI)

This report presents the results of work which included extensive modifications to HRI`s existing 3 ton per day Process Development Unit (PDU) and completion of the first PDU run. The 58-day Run 1 demonstrated scale-up of the Catalytic Two-Stage Liquefaction (CTSL Process) on Illinois No. 6 coal to produce distillate liquid products at a rate of up to 5 barrels per to of moisture-ash-free coal. The Kerr McGee Rose-SR unit from Wilsonville was redesigned and installed next to the US Filter installation to allow a comparison of the two solids removal systems. Also included was a new enclosed reactor tower, upgraded computer controls and a data acquisition system, an alternate power supply, a newly refurbished reactor, an in-line hydrotreater, interstage sampling system, coal handling unit, a new ebullating pump, load cells and improved controls and remodeled preheaters. Distillate liquid yields of 5 barrels/ton of moisture ash free coal were achieved. Coal slurry recycle rates were reduced from the 2--2.5 to 1 ratio demonstrated at Wilsonville to as low as 0.9 to 1. Coal feed rates were increased during the test by 50% while maintaining process performance at a marginally higher reactor severity. Sulfur in the coal was reduced from 4 wt% to ca. 0.02 wt% sulfur in the clean distillate fuel product. More than 3,500 gallons of distillate fuels were collected for evaluation and upgrading studies. The ROSE-SR Process was operated for the first time with a pentane solvent in a steady-state model. The energy rejection of the ash concentrate was consistently below prior data, being as low as 12%, allowing improved liquid yields and recovery.

Effect of liquefaction processing conditions on combustion characteristics of solvent-refined coal  

Science Conference Proceedings (OSTI)

One of several direct liquefaction processes currently under advanced stages of development is the Solvent-Refined Coal-I (SRC-I) process. A major SRC-1 product option is a low sulfur, low ash solid (SRC) which could be used as an electric utility boiler fuel much in the same manner that pulverized coal is currently fired in this type of combustion equipment. SRC-I processing has been performed using three variations in the manner in which mineral matter and unconverted coal are separated from the hot coal liquid. These processes are the Pressure Filtration Deashing (PFD), Anti-Solvent Deashing (ASD), and Critical Solvent Deashing (CSD). Since processing conditions may influence the combustion of SRC-I solids produced, an experimental program was carried out at both the bench and pilot plant scale to determine the influence of processing (i.e. solids separation method) and combustion conditions on carbon burnout of these three varieties of SRC solid boiler fuels. Included in this study was an examination of NO/sub x/ emissions (particularly for the CSD SRC and PFD SRC) with the objective of attaining low NO/sub x/ emissions without adversely affecting combustion efficiency. The work was carried out at the laboratory, bench and pilot plant scales employing Thermo-Gravimetric analyses, Drop Tube Furnace testing, and Controlled Mixing History furnace testing, respectively. Reactivity and NO/sub x/ emissions results were compared with those obtained from two coals previously tested and used as reference coals. One of these coals was a high reactivity Wyoming subbituminous coal and the other was a low reactivity Kentucky high volatile bituminous coal. The type of processing scheme used in the SRC-I deashing step was found to have a major impact on the combustion properties of the resultant solid SRC product.

ASPEN simulation of the SNG production process in an indirect coal-liquefaction plant  

DOE Green Energy (OSTI)

The synthetic natural gas (SNG) production process (methanation, CO-shift, and hydrogen removal) in an indirect coal-liquefaction plant was simulated using the Advanced System for Process Engineering (ASPEN). The simulation of the methanation unit agreed to within 12% of Fluor's design for converting carbon monoxide and carbon dioxide. A parametric study examined the effect of four important operating parameters on product composition, process thermal efficiency, and outlet temperature from the second methanation reactor. The molar split of gas feed to the CO-shift unit before methanation was varied from 0.2 to 0.6; variations of molar recycle ratio (0.01 - 0.67), molar steam-to-feed ratio (0.04 - 0.19), and feed temperature (478 - 533 K, 400-500/sup 0/F) to the first methanation reactor were also studied. A 50%-lower split improved thermal efficiency by 6%, but the mole % hydrogen and carbon monoxide in the product SNG required to meet pipeline-quality standards and temperature constraints were not met. Increasing the steam-to-feed ratio from 0.04 to 0.19 improved product quality but decreased thermal efficiency by 8%. By decreasing the feed temperature from 533 to 477 K (500 to 400/sup 0/F), product specifications and temperature constraints were met with no effect on thermal efficiency. However, it may be impractical to operate the reactor at 477 K (400/sup 0/F) because the kinetics are too slow. Increasing the recycle ratio from 0.4 to 0.67 had no effect on thermal efficiency, and temperature constraints and product specifications were met. The SNG production process should be optimized at recycle ratios above 0.67.

SRC-1: coal liquefaction demonstration plant. Project Baseline assessment report supplement  

Science Conference Proceedings (OSTI)

ICRC issued a Revised Baseline for the SRC-I Demonstration Project in order to incorporate the results of these research activities and the changes in the design that had occurred since FY82. The Revised Baseline, prepared by ICRC, provides the necessary information for any future government or commercial decisions relating to the design, construction and operation of an SRC-I-type coal liquefaction facility. No further activities to complete the design of the demonstration plant, or to proceed with construction are planned by DOE. The Project Baseline is an ICRC-documented reference for controlling any future project work and cost. The original Baseline was issued in March 1982; this summary document is available from National Technical Information Service (NTIS) as document number DOE/ORO/030540-T13. The Revised Baseline (dated April 1984) is available as document numbers DOE/OR/03054-T14 and T16. Supporting documentation, in the main concerned with research activities undertaken in support of the design, is also available from NTIS as DOE/OR/03054-T1 through T10 and DOE/OR/03054-1 through 125. The Baseline itself is made up of a documented design configuration, a documented estimate, in First Quarter Fiscal Year 1982 Dollars (1QFY82$), and a detailed schedule of the activities required to complete the project as of 3QFY82. The Baseline design is embodied in the 26 process design packages and other support documentation identified in the Baseline, as well as preliminary engineering flow diagrams prepared for all of the major process areas of the plant. All elements of the Project Baseline were developed within the constraints of the project criteria.

Advanced liquefaction using coal swelling and catalyst dispersion techniques. Quarterly technical progress report, July--September 1992  

Science Conference Proceedings (OSTI)

The experimental study of coal swelling ratios have been determined with a wide variety of solvents. Only marginal levels of coal swelling were observed for the hydrocarbon solvents, but high levels were found with solvents having heteroatom functionality. Blends were superior to pure solvents. The activity of various catalyst precursors for pyrene hydrogenation and coal conversion was measured. Higher coal conversions were observed for the S0{sub 2}-treated coal than the raw coal, regardless of catalyst type. Coal conversions were highest for Molyvan-L, molybdenum naphthenate, and nickel octoate, respectively. Bottoms processing consists of a combination of the ASCOT process coupling solvent deasphalting with delayed coking. Initial results indicate that a blend of butane and pentane used near the critical temperature of butane is the best solvent blend for producing a yield/temperature relationship of proper sensitivity and yet retaining an asphalt phase of reasonable viscosity. The literature concerning coal swelling, both alone and in combination with coal liquefaction, and the use of dispersed or unsupported catalysts in coal liquefaction has been updated.

Why sequence novel haloarchaea from Deep Lake?  

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

novel haloarchaea from Deep Lake? novel haloarchaea from Deep Lake? Antarctica's Deep Lake was isolated from the ocean by glaciers long ago, creating a salt water lake with a unique ecosystem for studying the evolution of marine microorganisms in harsh extremes. Among these microorganisms are haloarchaea, members of the halophile community which need high salt concentrations in order to grow. Haloarchaea are a distinct evolutionary branch of the Archaea, and are considered extremophiles. The haloarchaea from Deep Lake are naturally adapted to cold, nutrient-limited and high saline level conditions that would kill almost any other life. The enzymes in these naturally adapted microorganisms can provide insight into bioprospecting and bioengineering cold active and salt-adapted enzymes. Understanding how haloarchaea

Hydrological and solute budgets of Lake Qinghai, the largest lake on the Tibetan Plateau  

Science Conference Proceedings (OSTI)

Water level and chemistry of Lake Qinghai are sensitive to climate changes and are important for paleoclimatic implications. An accurate understanding of hydrological and chemical budgets is crucial for quantifying geochemical proxies and carbon cycle. Published results of water budget are firstly reviewed in this paper. Chemical budget and residence time of major dissolved constituents in the lake are estimated using reliable water budget and newly obtained data for seasonal water chemistry. The results indicate that carbonate weathering is the most important riverine process, resulting in dominance of Ca2+ and DIC for river waters and groundwater. Groundwater contribution to major dissolved constituents is relatively small (4.2 ± 0.5%). Wet atmospheric deposition contributes annually 7.4–44.0% soluble flux to the lake, resulting from eolian dust throughout the seasons. Estimates of chemical budget further suggest that (1) the Buha-type water dominates the chemical components of the lake water, (2) Na+, Cl?, Mg2+, and K+ in lake water are enriched owing to their conservative behaviors, and (3) precipitation of authigenic carbonates (low-Mg calcite, aragonite, and dolomite) transits quickly dissolved Ca2+ into the bottom sediments of the lake, resulting in very low Ca2+ in the lake water. Therefore, authigenic carbonates in the sediments hold potential information on the relative contribution of different solute inputs to the lake and the lake chemistry in the past.

Dewatering of Ambrosia Lake Mines  

SciTech Connect

The paper discusses the design of an aquifer depressurisation system using wells at Mt. Taylor Mine, Ambrosia Lake, New Mexico. The concepts discussed should be valid for any shaft of mine in a sandstone aquifer with predominantly matrix permeability. The system uses a number of wells surrounding the mine shaft to reduce the aquifer pressure in the vicinity of the shaft. The effect of various parameters such as number of wells, wellbore diameter, time and well location are considered. It is concluded that, with a properly designed system, the aquifer pressure and water inflow rate to the shaft may be reduced to less than 15% of their potential values in the absence of wells.

Geology of the Soda Lake geothermal area  

DOE Green Energy (OSTI)

The Soda Lake geothermal area is located in the Carson Desert, west-central Nevada. Hot springs activity has occurred in the Soda Lake area in the past, resulting in surface deposits which have motivated present geothermal exploration. The geothermal anomaly is in Quaternary clastic sediments which are as much as 4600 feet thick. The sediments consist of interbedded deltaic, lacustrine, and alluvial sediments. Quaternary basaltic igneous activity has produced cinder cones, phreatic explosions that formed the maar occupied by Soda Lake, and possible dikes. Opal deposition and soil alteration are restricted to a small area two miles north of Soda Lake. The location of hot springs activity and the surface thermal anomaly may be partially controlled by north-northeast-trending faults.

Great Lakes fish and the greenhouse effect  

SciTech Connect

This short article discusses data presented at the Second North American Conference on Preparing for Climate Change, held in Washington, D.C. Magnuson and Regier predicted that Great Lakes fish productivity may increase as a result of the increased water temperatures caused by the greenhouse effect. However, they also predicted that other indirect alterations could do more harm than good; for example, the effects of warming on lake oxygen levels, or wind, which affects the mixing of warm, cool, and cold water.

Lake Granbury and Lake Whitney Assessment Initiative Final Scientific/Technical Report Summary  

SciTech Connect

A team of Texas AgriLife Research, Baylor University and University of Texas at Arlington researchers studied the biology and ecology of Prymnesium parvum (golden algae) in Texas lakes using a three-fold approach that involved system-wide monitoring, experimentation at the microcosm and mesocosm scales, and mathematical modeling. The following are conclusions, to date, regarding this organismâ??s ecology and potential strategies for mitigation of blooms by this organism. In-lake monitoring revealed that golden algae are present throughout the year, even in lakes where blooms do not occur. Compilation of our field monitoring data with data collected by Texas Parks and Wildlife and Brazos River Authority (a period spanning a decade) revealed that inflow and salinity variables affect bloom formations. Thresholds for algae populations vary per lake, likely due to adaptations to local conditions, and also to variations in lake-basin morphometry, especially the presence of coves that may serve as hydraulic storage zones for P. parvum populations. More specifically, our in-lake monitoring showed that the highly toxic bloom that occurred in Lake Granbury in the winter of 2006/2007 was eliminated by increased river inflow events. The bloom was flushed from the system. The lower salinities that resulted contributed to golden algae not blooming in the following years. However, flushing is not an absolute requirement for bloom termination. Laboratory experiments have shown that growth of golden algae can occur at salinities ~1-2 psu but only when temperatures are also low. This helps to explain why blooms are possible during winter months in Texas lakes. Our in-lake experiments in Lake Whitney and Lake Waco, as well as our laboratory experiments, revealed that cyanobacteria, or some other bacteria capable of producing algicides, were able to prevent golden algae from blooming. Identification of this organism is a high priority as it may be a key to managing golden algae blooms. Our numerical modeling results support the idea that cyanobacteria, through allelopathy, control the timing of golden algae blooms in Lake Granbury. The in-lake experiments in Lake Whitney and Lake Waco also revealed that as golden algae blooms develop, there are natural enemies (a species of rotifer, and a virus) that help slow the population growth. Again, better characterization of these organisms is a high priority as it may be key to managing golden algae blooms. Our laboratory and in-lake experiments and field monitoring have shown that nutrient additions will remove toxicity and prevent golden algae from blooming. In fact, other algae displace the golden algae after nutrient additions. Additions of ammonia are particularly effective, even at low doses (much lower than what is employed in fish hatchery ponds). Application of ammonia in limited areas of lakes, such as in coves, should be explored as a management option. The laboratory experiments and field monitoring also show that the potency of toxins produced by P. parvum is greatly reduced when water pH is lower, closer to neutral levels. Application of mild acid to limited areas of lakes (but not to a level where acidic conditions are created), such as in coves, should be explored as a management option. Finally, our field monitoring and mathematical modeling revealed that flushing/dilution at high enough levels could prevent P. parvum from forming blooms and/or terminate existing blooms. This technique could work using deeper waters within a lake to flush the surface waters of limited areas of the same lakes, such as in coves and should be explored as a management option. In this way, water releases from upstream reservoirs would not be necessary and there would be no addition of nutrients in the lake.

Lake-atmosphere feedbacks associated with paleolakes Bonneville and Lahontan  

SciTech Connect

A high-resolution, regional climate model nested within a general circulation model was used to study the interactions between the atmosphere and the large Pleistocene lakes in the Great Basin of the United States. Simulations for January and July 18,000 years ago indicate that moisture provided by synoptic-scale atmospheric circulation features was the primary component of the hydrologic budgets of Lakes Lahontan and Bonneville. In addition, lake-generated precipitation was a substantial component of the hydrologic budget of Lake Bonneville at that time. This local lake-atmosphere interaction may help explain differences in the relative size of these lakes 18,000 years ago.

Energy and water in the Great Lakes.  

Science Conference Proceedings (OSTI)

The nexus between thermoelectric power production and water use is not uniform across the U.S., but rather differs according to regional physiography, demography, power plant fleet composition, and the transmission network. That is, in some regions water demand for thermoelectric production is relatively small while in other regions it represents the dominate use. The later is the case for the Great Lakes region, which has important implications for the water resources and aquatic ecology of the Great Lakes watershed. This is today, but what about the future? Projected demographic trends, shifting lifestyles, and economic growth coupled with the threat of global climate change and mounting pressure for greater U.S. energy security could have profound effects on the region's energy future. Planning for such an uncertain future is further complicated by the fact that energy and environmental planning and regulatory decisionmaking is largely bifurcated in the region, with environmental and water resource concerns generally taken into account after new energy facilities and technologies have been proposed, or practices are already in place. Based on these confounding needs, the objective of this effort is to develop Great Lakes-specific methods and tools to integrate energy and water resource planning and thereby support the dual goals of smarter energy planning and development, and protection of Great Lakes water resources. Guiding policies for this planning are the Great Lakes and St. Lawrence River Basin Water Resources Compact and the Great Lakes Water Quality Agreement. The desired outcome of integrated energy-water-aquatic resource planning is a more sustainable regional energy mix for the Great Lakes basin ecosystem.

THERMODYNAMICS OF PARTIALLY FROZEN COOLING LAKES  

SciTech Connect

The Rochester Institute of Technology (RIT) collected visible, SWIR, MWIR and LWIR imagery of the Midland (Michigan) Cogeneration Ventures Plant from aircraft during the winter of 2008-2009. RIT also made ground-based measurements of lake water and ice temperatures, ice thickness and atmospheric variables. The Savannah River National Laboratory (SRNL) used the data collected by RIT and a 3-D hydrodynamic code to simulate the Midland cooling lake. The hydrodynamic code was able to reproduce the time distribution of ice coverage on the lake during the entire winter. The simulations and data show that the amount of ice coverage is almost linearly proportional to the rate at which heat is injected into the lake (Q). Very rapid melting of ice occurs when strong winds accelerate the movement of warm water underneath the ice. A snow layer on top of the ice acts as an insulator and decreases the rate of heat loss from the water below the ice to the atmosphere above. The simulated ice cover on the lake was not highly sensitive to the thickness of the snow layer. The simplicity of the relationship between ice cover and Q and the weak responses of ice cover to snow depth over the ice are probably attributable to the negative feedback loop that exists between ice cover and heat loss to the atmosphere.

Lake Roosevelt Fisheries Evaluation Program; Meadow Creek vs. Lake Whatcom Stock Kokanee Salmon Investigations in Lake Roosevelt, 2001 Annual Report.  

DOE Green Energy (OSTI)

Lake Roosevelt has been stocked with Lake Whatcom stock kokanee since 1989 with the primary objective of creating a self-sustaining recreational fishery. Due to low return numbers, it was hypothesized a stock of kokanee, native to the upper Columbia River, might perform better than the coastal Lake Whatcom strain. Kokanee from Meadow Creek, a tributary of Kootenay Lake, British Columbia were selected as an alternative stock. Matched pair releases of Lake Whatcom and Meadow Creek kokanee were made from Sherman Creek Hatchery in late June 2000 and repeated in 2001. Stock performance between Lake Whatcom and Meadow Creek kokanee was evaluated using three performance measures; (1) the number of returns to Sherman Creek, the primary egg collection facility, (2) the number of returns to other tributaries and (3) the number of returns to the creel. Kokanee were collected during five passes through the reservoir via electrofishing, which included 87 tributary mouths during the fall of 2000 and 2001. Chi-square analysis indicated age two Meadow Creek kokanee returned to Sherman Creek in significantly higher numbers when compared to the Whatcom stock in 2000 ({chi}{sup 2} = 736.6; d.f. = 1; P < 0.01) and 2001 ({chi}{sup 2} = 156.2; d.f. = 1; P < 0.01). Reservoir wide recoveries of age two kokanee had similar results in 2000 ({chi}{sup 2} = 735.3; d.f. = 1; P < 0.01) and 2001 ({chi}{sup 2} = 150.1; d.f. = 1; P < 0.01). Six Lake Whatcom and seven Meadow Creek three year olds were collected in 2001. The sample size of three year olds was too small for statistical analysis. No kokanee were collected during creel surveys in 2000, and two (age three kokanee) were collected in 2001. Neither of the hatchery kokanee collected were coded wire tagged, therefore stock could not be distinguished. After two years of monitoring, neither Meadow Creek or Lake Whatcom kokanee appear to be capable of providing a run of three-year-old spawners to sustain stocking efforts. The small number of hatchery three-year-olds collected indicated that the current stocking methods will continue to produce a limited jacking run largely composed of precocious males and a small number of three-year-olds. However, supplemental creel data indicated anglers harvested two-year-old hatchery kokanee 30-45 days after release. Supplemental creel data should continue to be collected to accurately evaluate hatchery contributions to the creel.

Lake Roosevelt Fisheries Evaluation Program; Meadow Creek vs. Lake Whatcom Stock Kokanee Salmon Investigations in Lake Roosevelt, Annual Report 2002.  

DOE Green Energy (OSTI)

Lake Whatcom, Washington kokanee have been stocked in Lake Roosevelt since 1987 with the primary objective of creating a self-sustaining fishery. Success has been limited by low recruitment to the fishery, low adult returns to hatcheries, and a skewed sex ratio. It was hypothesized that a stock native to the upper Columbia River might perform better than the coastal Lake Whatcom stock. Kokanee from Meadow Creek, a tributary of Kootenay Lake, British Columbia were selected as an alternative stock. Post smolts from each stock were released from Sherman Creek Hatchery in late June 2000 and repeated in 2001. Stock performance was evaluated using three measures; (1) number of returns to Sherman Creek, the primary egg collection facility, (2) the number of returns to 86 tributaries sampled and, (3) the number of returns to the creel. In two repeated experiments, neither Meadow Creek or Lake Whatcom kokanee appeared to be capable of providing a run of three-year old spawners to sustain stocking efforts. Less than 10 three-years olds from either stock were collected during the study period. Chi-square analysis indicated age two Meadow Creek kokanee returned to Sherman Creek and to other tributaries in significantly higher numbers when compared to the Lake Whatcom stock in both 2000 and 2001. However, preliminary data from the Spokane Tribe of Indians indicated that a large number of both stocks were precocial before they were stocked. The small number of hatchery three-year olds collected indicated that the current hatchery rearing and stocking methods will continue to produce a limited jacking run largely composed of precocious males and a small number of three-year olds. No kokanee from the study were collected during standard lake wide creel surveys. Supplemental creel data, including fishing derbies, test fisheries, and angler diaries, indicated anglers harvested two-year-old hatchery kokanee a month after release. The majority of the two-year old kokanee harvested were from a direct stock at the Fort Spokane boat launch. Only Lake Whatcom kokanee were stocked from the boat launch, therefore stock performance was not evaluated, however the high success of the stocking location will likely increase harvest of hatchery kokanee in the future. Despite low numbers of the targeted three-year olds, Meadow Creek kokanee should be stocked when possible to promote fish native to the upper Columbia River.

Why sequence metagenomics in freshwater lakes?  

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

metagenomics in freshwater lakes? metagenomics in freshwater lakes? Aquatic microbial communities represent one of the largest reservoirs of genetic and biochemical diversity on the planet, and metagenomic studies have led to the discovery of novel gene families and a deeper understanding of how microbial communities mediate the flow of carbon and energy. However, most of these studies have been based on a static 'snap shot' of genetic diversity found under a particular set of environmental conditions. This study involves a metagenomic time-series to better understand how microbial communities control carbon cycling in freshwater systems.

Catalyst dispersion and activity under conditions of temperature- staged liquefaction. [Catalyst precursors for molybdenum-based catalyst and iron-based catalyst  

DOE Green Energy (OSTI)

Two coals, a Texas subbituminous C and a Utah high volatile A bituminous, were used to examine the effects of solvent swelling and catalyst impregnation on liquefaction conversion behavior in temperature staged reactions for 30 minutes each at 275{degree} and 425{degree}C in H{sub 2} and 95:5 H{sub 2}:H{sub 2}S atmospheres. Methanol, pyridine, tetrahydrofuran, and tetrabutylammonium hydroxide were used as swelling agents. Molybdenum-based catalyst precursors were ammonium tetrathiomolybdate, molybdenum trisulfide, molybdenum hexacarbonyl, and bis(tricarbonylcyclopentadienyl-molybdenum). Ferrous sulfate and bis(dicarbonylcyclo-pentadienyliron) served as iron-based catalyst precursors. In addition, ion exchange was used for loading iron onto the subbituminous coal. For most experiments, liquefaction in H{sub 2}:H{sub 2}S was superior to that in H{sub 2}, regardless of the catalyst precursor. The benefit of the H{sub 2}S was greater for the subbituminous, presumably because of its higher iron content relative to the hvab coal. Tetrabutylammonium hydroxide was the only swelling agent to enhance conversion of the hvab coal significantly; it also caused a remarkable increase in conversion of the subbituminous coal. The combined application of solvent swelling and catalyst impregnation also improves liquefaction, mainly through increased oil yields from the hvab coal and increased asphaltenes from the subbituminous. A remarkable effect from use of ammonium tetrathiomolybdate as a catalyst precursor is substantial increase in pristane and phytane yields. Our findings suggest that these compounds are, at least in part, bound to the coal matrix.

Sweet lake geopressured-geothermal project, Magma Gulf-Technadril/DOE Amoco Fee. Annual report, December 1, 1979-February 27, 1981. Volume I. Drilling and completion test well and disposal well  

DOE Green Energy (OSTI)

The Sweet lake site is located approximately 15 miles southeast of Lake Charles in Cameron Parish, Louisiana. A geological study showed that the major structure in this area is a graben. The dip of the beds is northwesterly into the basin. A well drilled into the deep basin would find the target sand below 18,000', at high pressures and temperatures. However, since there is no well control in the basin, the specific site was chosen on the 15,000' contour of the target sand in the eastern, more narrow part of the garben. Those key control wells are present within one mile of the test well. The information acquired by drilling the test well confirmed the earlier geologic study. The target sand was reached at 15,065', had a porosity of over 20% and a permeability to water of 300 md. The original reservoir pressure was 12,060 psi and the bottom hole temperature 299{sup 0}F. There are approximately 250 net feet of sand available for the perforation. The disposal well was drilled to a total depth of 7440'.

Review and Assessment of Commercial Vendors/Options for Feeding and Pumping Biomass Slurries for Hydrothermal Liquefaction  

Science Conference Proceedings (OSTI)

The National Advanced Biofuels Consortium is working to develop improved methods for producing high-value hydrocarbon fuels. The development of one such method, the hydrothermal liquefaction (HTL) process, is being led by the Pacific Northwest National Laboratory (PNNL). The HTL process uses a wet biomass slurry at elevated temperatures (i.e., 300 to 360°C [570 to 680°F]) and pressures above the vapor pressure of water (i.e., 15 to 20 MPa [2200 to 3000 psi] at these temperatures) to facilitate a condensed-phase reaction medium. The process has been successfully
