The ENCOAL Mild Coal Gasification Project, A DOE Assessment

Description: This report is a post-project assessment of the ENCOAL{reg_sign} Mild Coal Gasification Project, which was selected under Round III of the U.S. Department of Energy (DOE) Clean Coal Technology (CCT) Demonstration Program. The CCT Demonstration Program is a government and industry cofunded technology development effort to demonstrate a new generation of innovative coal utilization processes in a series of commercial-scale facilities. The ENCOAL{reg_sign} Corporation, a wholly-owned subsidiary of Bluegrass Coal Development Company (formerly SMC Mining Company), which is a subsidiary of Ziegler Coal Holding Company, submitted an application to the DOE in August 1989, soliciting joint funding of the project in the third round of the CCT Program. The project was selected by DOE in December 1989, and the Cooperative Agreement (CA) was approved in September 1990. Construction, commissioning, and start-up of the ENCOAL{reg_sign} mild coal gasification facility was completed in June 1992. In October 1994, ENCOAL{reg_sign} was granted a two-year extension of the CA with the DOE, that carried through to September 17, 1996. ENCOAL{reg_sign} was then granted a six-month, no-cost extension through March 17, 1997. Overall, DOE provided 50 percent of the total project cost of $90,664,000. ENCOAL{reg_sign} operated the 1,000-ton-per-day mild gasification demonstration plant at Triton Coal Company's Buckskin Mine near Gillette, Wyoming, for over four years. The process, using Liquids From Coal (LFC{trademark}) technology originally developed by SMC Mining Company and SGI International, utilizes low-sulfur Powder River Basin (PRB) coal to produce two new fuels, Process-Derived Fuel (PDF{trademark}) and Coal-Derived Liquids (CDL{trademark}). The products, as alternative fuel sources, are capable of significantly lowering current sulfur emissions at industrial and utility boiler sites throughout the nation thus reducing pollutants causing acid rain. In support of this overall objective, the following goals were established for the ENCOAL{reg_sign} Project: Provide sufficient quantity of products for full-scale test burns; Develop …

Production of mild gasification coproducts

Description: In summary, the co-product production runs performed by the SGI Development Center yielded sufficient simulated PDF (process derived fuel) and CDL (coal derived liquid) to meet the production needs for each of the four coals. The LFC Process appears to be an attractive method for upgrading all of the coals except for the Knife River Coal because of its limited yield and difficulty in processing. The Buckskin coal appears to be a slightly stronger candidate for upgrading than the other three coals because it has the greatest CDL yield and a more than 50% increase in heating value from ROM to PDF. (LFC processing of Usibelli and Sarpy Creek coal produces more PDF, but the heating value increase is less and the oil yields are low. Processing Knife River coal produces much less PDF but a greater heating value increase because of its higher moisture content). Finally, in all cases, the LFC Process removed significant percentage of the organic sulfur, clearly demonstrating its coal cleaning potential.

Production of mild gasification coproducts

Description: The LFC process upgrades young coals and lignites to a solid fuel which resembles higher rank coals and coproduces a liquid that resembles fuel oil. During the natural metamorphic process of pressure and heat, younger lower rank coals are converted to older higher rank coals over a period of greater than 100 million years. SGI's LFC process accomplishes this transformation in less than an hour, producing solid Process Derived Fuel (PDF) and liquid Coal Derived Liquid (CDL) coproducts. The coproduct samples will be produced from 4 different coals gathered from 3 major coal resource regions of the United States. Samples of the LFC process coproducts will be delivered to Government laboratories for test and characterization. Twenty kilograins of PDF will be delivered to each of 3 laboratories and 2 laters of CDL will be delivered to each of 4 laboratories. The characterization information will be returned to SGI and then will be incorporated into the final report.

Assessment of Research Needs for Coal Utilization

Description: The Coal Combustion and Applications Working Group (CCAWG), at the request of J.W. Mares (Assistant Secretary for Fossil Energy) and A.W. Trivelpiece (Director, Office of Energy Research), has reviewed and evaluated the U.S. programs on coal combustion and utilization. The important topical areas of coal gasification and coal liquefaction have been deliberately excluded because R and D needs for these technologies were reviewed previously by the DOE Fossil Energy Research Working Group. The CCAWG studies were performed in order to provide an independent assessment of research areas that affect prospects for augmented coal utilization. In this report, we summarize the findings and research recommendations of CCAWG.

Evaluation of fine-particle size catalysts using standard test procedures

Description: The goal of this project is to evaluate and compare the activities/selectivities of fine-particle size catalysts being developed in the DOE/PETC Advanced Research (AR) Liquefaction Program by using standard coal liquefaction activity test procedures. Since bituminous and subbituminous coals have significantly different properties, it is feasible that catalysts may perform differently with these coal types. Because all previous testing has been done with the DECS-17 Blind Canyon bituminous coal, it is important to develop the capability of evaluating catalysts using a subbituminous coal. Initial efforts towards developing a subbituminous coal test are aimed at comparing the reactivities of the Wyodak subbituminous coal and the Blind Canyon bituminous coal. Therefore, the same factorial experimental design was used with the Wyodak coal as was used previously with the Blind Canyon coal. In addition, PNL`s 6-line ferrihydrite catalyst precursor was used in the development of the Wyodak coal test procedure because this catalyst is the best powder catalyst found to date in Sandia`s tests with Blind Canyon coal. Results show that Blind Canyon coal yields higher DHP amounts in the reaction products and higher tetrahydrofuran conversions at the higher severity conditions. Wyodak coal gives higher heptane conversions and higher gas yields for all conditions tested.

Applications of the thermogravimetric analysis in the study of fossil fuels

Description: Thermogravimetric analysis (TGA) of coal and resid liquids and coal and resid solid residues, produced in coal liquefaction and coal- derived resid hydroprocessing in SCTBR (short contact time batch reactor), provides a sensitive, rapid, reproducible means of studying kinetics and mechanisms of fossil fuel conversion processes. SimDis TGA and custom built TGA system for distillation provide unique means to characterize liquid fuels for boiling point distribution. TGA provides information about various weight loss processes that can be a reflection of physical and chemical structure of fossil fuel samples. This technique can also yield TG scanning parameters, such as volatile matter, fixed carbon, ash, etc., for monitoring the conversion processes. One example is onset and rate of retrograde reactions during coal liquefaction.
