A high-pressure Process Development Unit (PDU) has recently been constructed by the Institute of Gas Technology (IGT) to develop a data base for the ash-agglomerating, fluidized-bed gasification characteristics of different coals at elevated pressures. It has been operated at pressures up to 300 psig and at temperatures dictated by individual coal gasification requirements. Sufficient data have been obtained from this PDU to characterize the effect of pressure on the gasification of Montana Rosebud subbituminous coal and North Dakota lignite. Data with bituminous coals at pressures up to 135 psig have also been obtained. Encouraged by its recent successful operation at pressures up to 300 psig, IGT has recently upgraded the PDU to enable testing at pressures to 500 psig. A program for testing different American coals at this pressure has just begun. The recent testing and upgrading has been funded by the Gas Research Institute. 6 refs., 6 figs., 3 tabs.
