Te在丙烷选择氧化制丙烯醛反应中的作用

Effect of Te on the Reaction of Selective Oxidation of Propane to Acrolein

采用催化剂反应性能评价的方法,对丙烷和丙烷选择氧化反应的有关中间体或其探针分子(如丙烯、异丙醇)在MoPO/SiO2和MoPTeO/SiO2催化剂上的反应行为进行了考察,用以探明Te组分的添加对丙烷选择氧化制丙烯醛的有关中间体转化为目的产物的作用.结果表明,Te的加入有利于中间体丙烯转化为丙烯醛.

To elucidate the effect of Te on MoPTeO/SiO2 catalyst for the selective oxida tion of propane to aerolein,the oxidative conversions of propane, possible intermediates or their probe molecules of the selective oxidation of propane to acrolein on MoPO/SiO2 and MoPTeO/ SiO2 catalysts were studied. The results suggested that the addition of Te to the catalyst plays a key role in the convertion of propene to acrolein.
