Development of hollow fiber catalytic membrane reactors for high temperature gas cleanup
The technology employed in the Integrated Gasification Combined Cycle (IGCC) permits burning coals with a wide range of sulfur concentrations. Emissions from the process should be reduced by an order of magnitude below stringent federal air quality regulations for coal-fired plants. The maximum thermal efficiency of this type of process can be achieved by removing sulfur and particulates from the high temperature gas. The objective of this project was to develop economically and technically viable catalytic membrane reactors for high temperature, high pressure gaseous contaminant control in IGCC systems. These catalytic membrane reactors were used to decompose H{sub 2}S and separate the reaction products. The reactors were designed to operate in the hostile process environment of the IGCC systems, and at temperatures ranging from 500 to 1,000. Feasibility of the membrane reactor process for decomposition of hydrogen sulfide was demonstrated; permeability and selectivity of molecular-sieve and Vycor glass membranes were studied at temperatures up to 1,000 C; experimental study of hydrogen sulfide in the membrane reactor was completed; and a generalized mathematical model was developed for the simulation of the high temperature membrane reactor.
