摘　　要：综述了沸石分子筛催化剂的组成中主催化活性组分、负载金属改性对于烃类转化规律的影响。不同催化剂的活性组分有别,硅铝比和骨架孔道的不同其催化作用也不同;催化剂的金属改性种类和负载量很大程度上改变了催化剂的催化活性和选择性,对于烃类转化影响很大。由此总结分子筛催化剂的开发在于骨架结构、负载改性类型及负载量。The effects of main catalytic activity componentsandsupported metal modification were reviewed in the composition of zeolite molecular sieve catalysts. The active components of the different catalysts are different. If the ratio of silicon to aluminum or skeleton is different, then its catalytic effect is different. The metal rnodification type and the loading amount of the catalyst greatly change the catalytic activity and selectivity of the catalyst, and have great influence on the hydrocarbon conversion. It is concluded that the development of molecular sieve catalyst is the skeleton structure, the type of load modification and the loading.
