Abstract: By studying the partial oxidation of cokeovengas (COG) and CH₄ in oxygenpermeable membrane reactor through designing experiments and test of oxygen permeation, a “reformingpermeation” model in a membrane reactor is proposed. A membrane reactor is composed of an oxygenpermeable membrane and a catalyst bed. The catalyst bed mainly realizes the pyrolysis of CH₄ and catalytic reforming, and metal particles on the membrane surface accomplishes the “adsorption—spillover—oxidation” processes of the reducing compositions in the gas to promote conduction of oxygen ion in mixed conductors.

Key words: catalyst bed, cokeovengas (COG), mixed ionicelectronic conductingceramics, oxygenpermeable membrane reactor
