摘　　要：制备了一种负载型Re基催化剂Re2O7/γ-Al2O3,用于直链内烯烃与乙烯歧化制备α-烯烃。结果表明,以C11～C12直链内烯烃为原料,反应温度60℃,反应体积空速1 h-1,反应压力3 MPa的条件下,C11～C12烯烃的单程转化率达到90.0%,歧化选择性达到85.98%。Abstract： Preparation of supported Re based catalysts modified Re207/.y-A1203, used in the preparation of α-olefin metathesis of olefins with ethylene in the straight chain internal olefins process. The results showed that to Cn ,to C12 ,a straight chain internal olefin as raw material, the reaction temperature of 60 ℃ ,the reaction volume airspeed 1 h -1, C11- C12 ,olefin-way conversion rate of 90.0% under the con- ditions of the reaction pressure 3 MPa,metathesis selectivity 85.98%.
