摘　　要：对苯氧化制顺酐催化剂技术进行了综述,介绍了目前国内苯法顺酐装置的情况,主要针对催化剂的工艺技术发展,主要从固定床载体技术、催化剂的制备过程、氧化反应的机理和催化剂中各元素的主要作用等四个方面对催化剂进行了阐述,针对载体的选择趋势、催化剂制备工艺改进、钒价态的调控以及助剂的使用等方面进行了重点介绍。The technology of the catalyst in the oxidation of benzene to maleic anhydride during the recent years was described. Also this paper the present situation of maleic anhydride producing from benzene as raw materials was introduced. The catalyst support, the preparation method of catalyst, the mechanism of the oxidation and the roles of promoters in the oxidation of benzene to maleic anhydride were reviewed. The trend of selecting catalyst support, the improvement prepared method, the vanadium oxidation states and the promoter were discussed.
