Abstract
The catalytic performances of zinc molybdate for oxidative dehydrogena tion of isobutane are reported. The effects of N-2, water steam and th e volume ratio of isobutane/O-2 in feed gas are studied. The selectivi ty to isobutene increases with the increasing of isobutane/O-2 ratio, but the conversion of isobutane decreases. The steam added in feed gas can improve the isobutene selectivity while N-2 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.
