This report covers the activities for the Exxon Catalytic Coal Gasification Development Program during the quarter October 1 to December 31, 1978. Construction of three bench scale units to study catalyst recovery was begun. These units include a one-gallon stirred tank for char digestion studies, a series of leaching tanks for char-liquid separation studies, and a fluidized bed reactor for char combustion studies. Construction of a bench unit to study cryogenic separation of CO/sub 2/ from product gas was also begun. In addition, the construction of a bench apparatus to study reactions of product and recycle gas in furnace and heat exchanger tubes was started. The 1/4 ton/day Fluid Bed Gasifier was operated to produce char for the Process Development Unit (PDU) startup and catalyst recovery studies. Construction of a single stage catalyst recovery pilot plant was completed. This unit was built to test a proposed catalyst recovery system for the Process Development Unit (PDU). The design of the on-line data acquisition system for the PDU was completed. A fixed-bed bench scale gasification unit has been recommissioned to better define catalytic gasification kinetics. Work continued on a revised offsites facilities definition and cost estimate to update the CCG Commercial Plant Study Design. Work continued also on the study to determine the incentives and data needs for a cryogenic separation system to remove acid gases from the product gas.
