The objectives of this program are to obtain an initial data base from a fluidized-bed ash-agglomerating gasifier operating at pressures up to 500 psig on bituminous, subbituminous, and lignite coals. Four gasification tests were conducted with Pittsburgh Seam coal on the 8-inch fluidized-bed process development unit (PDU) at pressures up to 200 psig. A heat and mass balance prepared from gasification data and samples obtained at 100 psig operating pressure show an average ash discharge composition of 80% ash and a coal conversion of 89%. All engineering work is essentially complete and several quotations for equipment were received for upgrading the PDU for operation at pressures to 500 psig. In the next quarter, additional superheat will be added to the process gas supply whereupon tests will be completed with bituminous and initiated with subbituminous coal.
