A 32-month gasifier mechanistic study and downstream unit process development program for the pressurized ash-agglomerating fluidized bed gasification system: Quarterly report, January 1-March 31, 1985

Technical Report ·
OSTI ID:5220664
Work is underway at KRW Energy Systems to develop operating experience and process performance information for a pressurized fluidized-bed agglomerating-ash coal gasification system. The KRW Process Development Unit at Waltz Mill, PA, will be operated from 1985 through 1987 to test (1) an in-bed desulfurization and alkali removal system, and (2) an external hot gas zinc ferrite desulfurization system, and (3) an intergrated in-bed/external-bed system to provide for collection and anaylsis of mechanistic process data. An exploratory test(TP-036-1) was conducted in December 1984 on the newly installed in-bed desulfurization system. Five set points were completed, including an initial air-blown baseline set point without dolomite and four in the dolomite, desulfurization mode. An evaluation of spent reactivity decreased rapidly as the utilization during TP-036-1 indicated that sorbent reactivity decreased rapidly as the utilization of the sorbent approached 60%. 31 figs., 18 tabs.
