The objective of the project is to extend the ash-agglomerating fluidized-bed gasification data base of important American coals to pressures of 500 psig. A series of gasification tests in IGT's 8-inch process development unit (PDU) with lignite and subbituminous coal produced steady-state data at 100, 200, and 300 psig. After GRI reviewed an analysis of the data, the PDU system was upgraded to 500 psig operating capability. A matrix of gasification tests were then completed with lignite and subbituminous coal of 200, 300, and 450 psig. Eastern bituminous-coal-gasification results from the PDU were limited to pressures of 150 psig due to defluidization caused by coal caking. These bituminous-coal-gasification data clearly reveal that a proportionally small addition of a coal char or limestone, for desulfurization, can control coal caking to obtain data at higher pressures in the PDU. An extensive process data analysis will be conducted from the matrix of gasification data obtained with the western coals and presented in a forthcoming topical report.
