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 have been completed, one each with Pittsburgh Seam, Kentucky No. 9 bituminous, and two with Rosebud subbituminous coal. Heat and mass balances were prepared from gasification data on Rosebud coal at 96 and 195 psig operating pressures and show coal conversions of 92% and 91%, respectively. PDU process system improvements completed this quarter include the installation of: Magnets to remove storage hopper rust contamination of the coal feed, and superheater insulation to raise process steam superheat by 300F . In the next quarter, test work will be completed for obtaining steady-state data on subbituminous and lignite coals at 100, 200, and 300 psig reactor pressure.
