摘要/Abstract

摘要： 采用有机相法制备钒磷氧(VPO)催化剂，并在合成过程中加入Ti/Zr助剂，使用微型固定床反应器评价其催化正丁烷选择性氧化制顺酐的性能，考察了不同助剂元素及其化合物形式和添加量对催化剂性能的影响，分析了添加助剂对催化剂晶相及微观形貌的影响. 结果表明，加入助剂未改变催化剂的晶相结构，但促进了活性相(VO)2P2O7生成，且使反应后催化剂微观形貌发生改变，片层更破碎，活性相暴露，同时生成了利于反应的微量V5+；助剂金属Ti和Zr与V元素间的相互作用对催化剂表面P浓度及V价态都有一定影响；与不加助剂的VPO催化剂相比，相同反应条件下，Ti/Zr助剂修饰的VPO催化性能显著提高，摩尔比Zr/V为1.5%的Zr(NO3)4为助剂的催化剂的催化性能最佳，稳定状态下正丁烷的转化率高达99.1%，顺酐收率为54.4%.
