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 inβ 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 ofiso-butane and olefin isomers (ortert-olefins)in light gasoline, which enriched raw material resources for alkylation and etherification processes.
