| 摘 要： | 研究了钼酸锌对异丁烷氧化脱氢反应的催化作用,考察了原料气中烷氧体积比、N2及水蒸汽对反应结果的影响.提高反应原料气中的烷氧体积比能够提高异丁烯选择性,但也会降低异丁烷的转化率.原料气中加入N2不利于反应;而加入水蒸汽可提高异丁烯选择性.催化剂表面主要是弱酸中心,对反应有利.

| Abstract: | The catalytic performances of zinc molybdate for oxidative dehydrogenation of isobutane are reported. The effects of N2, water steam and the volume ratio of isobutane/O2 in feed gas are studied. The selectivity to isobutene increases with the increasing of isobutane/O2 ratio, but the conversion of isobutane decreases. The steam added in feed gas can improve the isobutene selectivity while N2 in feed gas shows an unfavorable influence. The acid sites on the surface of zinc molybdate are mainly weak ones, which can promote the oxidative dehydrogenation of isobutane into isobutene. |
