摘要
研究了不同分子筛负载的Pt催化剂上丙烷与苯的烷基化反应.结果表明,Pt/HZSM.5具有较好的催化性能.在0-0.3%范围内提高Pt负载量可以提高催化剂的催化活性和生成C9以及C10+芳烃的选择性,降低非芳烃产物的选择性.较低的反应温度、较高的苯俩烷摩尔比和较高的空速有利于烷基芳烃的生成.
The alkylation of propane with benzene over Pt catalysts supported on different zeolites was studied. Pt/HZSM-5 shows much higher selectivity for alkylbenzene than other catalysts. With increasing Pt loading from 0 to 0.3 %, the conversion of propane and the selectivity for C9 and C10 + aromatics increase, whereas the selectivity for non-aromatics decreases. The effects of the reaction temperature, space velocity, and benzene/ propane molar ratio on the alkylation of propane with benzene over Pt/HZSM-5 zeolite were investigated. Low reaction temperature, high space velocity, and high benzene/propane molar ratio favor the formation of alkylbenzene.
