| 英文摘要 | a dense membrane tube made of ba0.5sr0.5co0.8fe0.2o3-delta (bscf) was prepared by plastic extrusion from bscf oxide synthesized by the complexing edta-citrate method. the membrane tube was used in a catalytic membrane reactor for oxidative coupling of methane (ocm) to c-2 without an additional catalyst. at high methane concentration (93%), about 62% c-2 selectivity was obtained, which is higher than that achieved in a conventional reactor using the bscf as a catalyst. the dependence of the ocm reaction on temperature and methane concentration indicates that the c-2 selectivity in the bscf membrane reactor is limited by high ion recombination rates. if an active ocm catalyst (la-sr/cao) was packed in the membrane tube, c-2 selectivity and ch4 conversion increased compared to the blank run. the highest c-2 yield in the bscf membrane reactor in presence of the la-sr/cao catalyst was about 15%, similar to that in a packed-bed reactor with the same catalyst under-the same conditions. however, the ratio of c2h4/c2h6 in the membrane reactor was much higher than that in the packed-bed reactor, which is an advantage of the membrane reactor.
