The project consist of the following main activities: (1) Design of catalytic hollow fiber membrane reactors. Single and multiple hollow-fiber membranes were studied in reactor/permeation cells made from stainless steel or quartz tubes. Modification of the hollow fiber membrane with catalysts was performed by aqueous impregnation, vapor deposition, and utilization of packed-bed reactors. (2) Investigation of gas separations and catalytic reactions in membrane reactors. Permeation of pure gases and gas mixtures was studied as a function of temperature. Pure component catalytic studies on the decomposition of H[sub 2]S was typically studied using 10% H[sub 2]S diluted in He. The H[sub 2]S and H[sub 2] concentrations were measured in both the tube and shell sides of the membrane reactor to determine the degree of chemical equilibrium shift. (3) Process development of the cleanup system using a simulated gas stream with a composition similar to that from an IGCC system. Catalytic studies using the IGCC gas composition will be performed according to the procedure used in the H[sub 2]S experiments. The conditions for optimum conversion in a gas mixture will be investigated.
