The overall objective of the program is to develop a preliminary assessment of the potential of a hydrogen generation process based upon reactions involving char, steam, lime, and metal salt additives. Design, construction, and preliminary checkout tests of the elevated pressure fluid bed reactor have been completed. A review of the safety of operation of the reactor system was completed, and TRW management approval to operate the system for char gasification studies up to a temperature of 750/sup 0/C and a pressure of 150 psi was granted. Catalyst transport studies were completed under the Gasification Reaction Physical-Chemical Properties task. In the studies completed potassium carbonate catalyst, applied to a high surface area silicon carbide support material and immersed in a char bed, was shown to be mobile during the char-steam reaction and able to catalyze, though somewhat ineffectually, the char gasification reaction(s). Gasification experiments were carried out in the fixed-bed reactor system to determine the effects which a small oxygen partial pressure would have on the product composition and gasification rate of the potassium carbonate catalyzed steam-char-limestone reaction. The engineering analysis effort has paralleled the laboratory research to the extent that the selected laboratory data have been incorporated into an updated version of the conceptual commercial process design for the TRW coal to H/sub 2/ process.
