摘要
报道了不同方法合成β沸石的FCC反应性能,并考察了β沸石的硅铝比对FCC反应产品分布的影响。结果表明:β沸石应用于FCC,与高硅ZSM-5相比,具有提高汽油产率及辛烷值的功能;另外β沸石较高硅ZSM-5表现出更强的异构化功能,具有提高异丁烷和轻汽油异构烯烃(或叔碳烯烃)产率的作用,可丰富烷基化技术和醚化技术的原料来源。
β zeolites synthesized by various methods were used to study the FCC（fluid catalytic cracking） reactions and to explore the impact of silicon/aluminum ratio in β zeolites on FCC product distributions. Compared to high silicon-containing ZSM-5 zeolites, β zeolites in FCC increased both octane number and yield of gasoline. Also, β zeolite showed a stronger functionality of isomerization with enhanced yields of iso-butane and olefin isomers（or tert-olefins）in light gasoline, which enriched raw material resources for alkylation and etherification processes.
