▣ Abstract

Membrane reactors have been suggested as a novel technology to enable gas separation and fuel conversion to take place simultaneously in a single unit. Possessing the mixed ionic and electronic conductivity, perovskite membranes or ion transport membranes permeate selectively oxygen ions from the air (feed) side to the sweep gas or reactive gas (permeate) side of the membrane, driven by the oxygen chemical potential gradient across the membrane at elevated temperature. When a fuel such as methane is introduced into the permeate side as a sweep gas, hydrocarbon oxidation reactions occur by reacting the fuel with the permeated oxygen. The fuel can be partially reformed, completely oxidized or converted to produce higher hydrocarbons. To utilize this technology more effectively, it is necessary to develop a better understanding of oxygen transport and hydrocarbon conversion in the immediate vicinity of the membrane or on its surface. In this talk, a number of membrane materials and catalysts for such membrane reactors and their operating mechanism will be discussed in detail.
