| 英文摘要 | for the dehydrogenation of c(2)h(6) with co(2) to c(2)h(4), a silicalite-2 zeolite supported fe-mn catalyst has been developed, with an achievement of 93% of c(2)h(4) selectivity and 66% of c(2)h(6) conversion. the promotion of mn to the fe/si-2 catalyst lies not only in increasing c(2)h(4) selectivity but also in improving the catalytic stability greatly. a thermo-balance was employed to investigate the behavior of coke deposition on fe/silicalite-2 and fe-mn/silicalite-2 catalysts during c(2)h(6) dehydrogenation. by studying the effects of reaction temperature and partial pressures of c(2)h(6) and co(2) on coke deposition, the kinetic parameters of the coking reaction were satisfied and the corresponding coking reaction kinetics equations were thus established. the rate of coke deposition on fe-mn/silicalite-2 is much less than that on fe/silicalite-2, due to the modification of mn to the fe/silicalite-2 catalyst. the promotion of mn to the improvement of the catalytic stability of the fe/silicalite-2 catalyst results from the great prohibition of coke formation on fe-mn/silicalite-2 catalyst surfaces.
