| 摘 要： | 通过对一系列添加不同助剂的VPO催化剂的研究,揭示了助剂对正丁烷选择性氧化制顺酐的促进作用.各种助剂的加入可明显提高催化剂的活性和选择性,将反应活性和选择性与催化表面结构相关联发现,比表面积和表面氧化还原中心的增加导致活性的提高,可是,高选择性却与催化剂具有适宜的表面酸中心有关.

| Abstract: | A series vanadyl pyrophosphates modified by different additives were used as catalysts for the oxidation of n-butane to maleic anhydride(MA).Their performance were investigated and found that adding of various promoters improved the catalytic performance remarkably on both conversion and selectivity.It was also found that increase of surface area would result in the higher activity,but the selectivity associate with turnover frequency. |
