在丙烯氧化脱氢芳构化制苯过程中,应用脉冲微型反应装置,对一些金属氧化物催化剂的催化性能进行了考察,指出Bi_2O_3-SnO_2催化剂在600℃的摄度下,丙烯的转化率可达85.4％,苯的选择性达50.2％,同时初步探讨了反应历程和催化剂的作用机理。
In the process of oxidative dehydrogenation of propylene to benzene, the catalytic performance of some metal oxide catalysts was investigated by means of pulsed micro-reactor. It was pointed out that the conversion of propylene at 600 ℃ could be obtained by Bi 2 O 3 -SnO 2 catalyst Up to 85.4%, the selectivity of benzene up to 50.2%. At the same time, the reaction mechanism and mechanism of action of catalyst were discussed.
