Title: Operations: CO/sub 2/ acceptor process gasification pilot plant. Final report, Volume 6, book 1 of 2, January 1972--June 1973

Abstract

The Consolidation Coal Company CO/sub 2/ Acceptor Gasification Process pilor plant began shakedown operations in January of 1972. With development of a standard start-up procedure and elimination of most of the mechanical problems, the plant is beginning to produce the data required for process evaluation and the design of larger plants. The process areas investigated have been those related to maintaining independent control of the flow rates of char and acceptor between the two fluidized bed reactors. These areas include: fluidization; the char-acceptor interface; acceptor circulation; and char combustion. Solution of problems in these areas resulted in the successful transition from start-up to integrated operation during Run 10. During Run 10, 100 hours of char combustion were achieved. During this time no 0/sub 2/ breakthrough occurred, no slagged ash or transient liquid deposits were found and a high carbon burnout was achieved. One of the features of the CO/sub 2/ Acceptor Process is that the raw product gas contains a high ratio of H/sub 2/ to carbon oxides, compared with all other gasification processes. It may be possible to operate the methanation section without a water gas shift reactor and without purposeful scrubbing of CO/sub 2/ from the gas. Operationmore » of the methanation section will be necessary to demonstrate the behavior of this unique gas.« less
