Selective Oxidation of Propane over Bismuth Vanadomolybdate Catalysts

钼钒酸铋体系催化剂上丙烷的选择氧化反应李静，宋伟，窦伯生（中国科学院长春应用化学研究所长春１３００２２）关键词丙烷，选择氧化，钼钒酸铋，助剂，丙烯醛合理利用天然气及石油裂解气为人们所关注。由于烷烃较相应烯烃反应活性低，使其在工业上的应用远不及烯烃，相...

We have investigated the catalytic properties of scheelite-type oxide Bi1-r/3V1-x-MoxO4 in the selective oxidation of propane to acrolein.When x is 0. 45, the catalyst Bi0.85V0.55Mo.45O4 shows good catalytic effect; the selectivity for acrolein is 23% at 54% conversion of propane. Monovalent silver promoter markedly improves catalytic performance of the bismuth vanadomolybdate Bi0.85V0.55Mo0.45O4. Under the optimum reaction condition. the catalyst Ag0.01Bi0.85V0.54Mo0.45O4 shows much better catalytic performance with the selectivity for acrolein being 32% at 52% conversion of propane.
