Abstract:在小型常压固定床反应器中研究了不同离子浸渍改性对纳米ZSM-5固体酸催化剂上丁烷和丁烯转化的影响.结果表明, 混和碳四中异丁烷比正丁烷易转化, 丁烯异构体的转化与其在原料中的含量有关.在贫烯烃原料中, 丁烯倾向于生成.在富丁烯原料中, 丁烯倾向于转化.但在两种情况下, 产物中各丁烯含量大体上按异丁烯、顺反-丁烯-2和丁烯-1顺序递减.采用锌离子改性时异丁烷转化率提高、正丁烷转化率降低.锌离子改性有利于芳烃选择性, 但是副产物甲烷和乙烷的产率也较高; 铁离子改性对丁烷和丁烯的转化影响不大, 但能减少甲烷和乙烷的生成, 并提高芳烃选择性; 与锌改性相比, 锌钠双离子改性降低了异丁烷、正丁烷和丁烯-1的转化率, 减少了芳烃产率, 但能明显促进丙烯和丁烯的生成.上述结果为碳四液化气综合利用提供了有益信息.
