    The modified shape-selective zeolite, are primary active component in the additives. Gasoline olefin are changed into aromatic hydrocarbon and alkane by aromatization reaction and hydrogen transfer reaction, at the same time, the gasoline octane number has been enhanced.
    本文在文献调研的基础上,根据汽油烯烃分子容易进行二次反应的原理,利用改性择形分子筛等复合分子筛作为主要活性组分来制备降烯烃助剂LAP,使催化裂化汽油中烯烃通过芳构化反应和氢转移反应而转化生成芳烃和烷烃等,以达到在降低汽油烯烃含量的同时提高汽油辛烷值的目的。
    However, as one of its disadvantages, this kind of gasoline octane number increase in MFT is mainly due to the arene in gasoline.
    但其缺点是汽油辛烷值的提高主要来源于芳烃。
