摘要: 通过实验设计和透氧量测定研究焦炉煤气(cokeovengas,COG)或天然气中的甲烷在透氧膜反应器中的部分氧化重整途径,提出反应器内的“重整透氧”机理模型.在由混合导体和催化床构成的透氧膜反应器中,催化床主要实现甲烷裂解和催化重整的功能,在膜表面处的催化金属微粒完成了还原性气体的“吸附—溢流—氧化”过程,进而强化混合导体内部的氧离子传导.

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
