由于受到环境保护的限制，炼油工业必须实现汽油的无铅化，同时随着汽车行业对汽油辛烷值的要求不断提高，因此生产高辛烷值的无铅汽油是炼油工业的当务之急。异丁烷与 C3、 C4烯烃烷基化所制得的 C8烷基化油是高辛烷值无铅汽油最洁净的汽油调合组分，其 RON值一般为 90～ 94，
Due to the restriction of environmental protection, the refinery industry must realize the lead-free of gasoline. At the same time, as the automobile industry’s requirement for the octane number of gasoline continuously increases, the production of high-octane unleaded gasoline is the top priority of the oil refining industry. C8 alkylate obtained by alkylation of isobutane with C3, C4 olefins is the cleanest gasoline blending component of high-octane unleaded gasoline with a RON value of 90-94,
