Under this program (DOE Contract No. DE-AC01-76ET10237), the Ash Agglomerating Gasifier (AAG) pilot plant was modified to facilitate extended tests with coal. Coal gasification tests were conducted on the modified AAG pilot plant. After successful coke shakedown tests, Montana subbituminous, washed Illinois No. 6 bituminous, washed and run-of-mine (ROM) Western Kentucky No. 9 bituminous, washed Pittsburgh seam bituminous, and washed Western Kentucky Nos. 9 and 11 mixed bituminous coals were processed. A total of 22 tests were conducted; 560 tons of coal were gasified and 780 hours of operation were logged. The following milestones were achieved: The AAG pilot plant was modified to accept raw coal feed. Direct feeding of raw bituminous coal (387 tons) to the gasifier eliminated the need for pretreatment before processing. Coal gasification under the steam-oxygen mode produced fuel gas having heating values up to 284 Btu/SCF. Coal conversion efficiencies up to 96% were attained when elutriated cyclone fines were recirculated to the reactor. Stable conditions for the ash agglomeration of washed and ROM Western Kentucky No. 9 bituminous, washed Pittsburgh seam bituminous, and washed Western Kentucky Nos. 9 and 11 mixed bituminous coals were confirmed. A complete documentation of the AAG pilot plant equipment history during the span of this program has been presented.
