In the final hydrocarbonization experiment with Wyodak subbituminous coal, the coal was hydrocarbonized at 1100/sup 0/F and 300 psig in the recirculating fluidized bed. Two-dimensional pyrolysis behavior of an eastern bituminous coal (Pittsburgh seam) continues to be examined. Results to date indicate that swelling is significantly more pronounced at very low heating rates. Several activities in progress are related to inspection techniques for wear- and process-resistant coatings. Experimental investigations of fireside corrosion on tubing from a fluidized bed combustor have proceeded with metallographic examination and analyses of the scale formed during the test exposure. Methods for nondestructively determining remaining tube wall thickness and scale thickness were developed. Failure prevention and analysis work was aimed at several parts from the Solvent Refined Coal Plant in Ft. Lewis, Washington. The mechanical design of the gas-fired potassium boiler system was completed with the issue of the last four drawings. One electrical and five instrument and control drawings were completed and some fabrication work was completed. Surveys of industrial coal conversion capabilities continued with emphasis on rotating components, valves, hot gas cleanup devices, and heat recovery equipment. Process and program analysis research studies continued with work on low-Btu gasification, direct combustion, advanced power conversion, liquefaction, high-Btu gasification, in-situ gasification, and beneficiation. In the fossil energy environmental project, a first draft of a landfill assessment report was issued for review. Work continued on the Environmental Monitoring Handbook and Pipeline Gas Programmatic Assessment.
