摘　　要：研究了反应工艺条件和反应器结构与材质在Ａｇ－Ｂｉ－Ｖ－Ｍｏ－Ｏ催化剂体系下对丙烷部分氧化制取丙烯醛反应的影响，确定较合适的反应工艺条件为：温度４９０℃，空速３０００毫升／（克催化剂小时），Ｃ３Ｈ８／Ｏ２＝０．７—０．８，Ｎ２含量为１０％—１５％。且研究表明反应器的结构与材质对催化剂的反应性能影响很大，反应器床层上端应有一定的自由空间，玻璃反应器比铁反应器能获得较高的丙烷转化率和丙烯醛收率。根据反应温度和反应器结构对丙烷氧化反应的影响。The effects of reaction conditions and structure and materials of construction of the reactor on the partial oxidation of propane to acrolein over Ag Bi V Mo O catalysts have been investigated.The results showed that suitable reaction conditions were 490℃,3000ml/gcat·h,C 3H 8/O 2=0 7—0 8,N 2=10%—15%,and the structure and material of construction of reactor affected product distribution severely.The catalyst packed in glass reactor revealed higher activity and selectivity than that in iron reactor.Based on the effects of both reaction temperature and reactor material on the catalytic performance,we inferred that acrolein was formed via propene which came from propane by dehydrogenation.
