摘　　要：对用碳四做原料生产烷基化汽油的杂质影响和处理工艺路线选择进行探讨,所选预处理工艺技术在国内某600kt/a异辛烷装置得到工业应用,处理后的烷基化原料中丁二烯、二甲醚、甲醇含量均降至50ppm以下,完全满足进料要求。同时,其1-丁烯异构化为2-丁烯的异构化率大于70%,丁烯收率大于98%。This paper discusses the impact on alkylate impurities and the selection of the treatment process based on C4 as raw material to produce alkylation gasoline. The selected pretreatment technology is used in a domestic600 kt / a isooctane plant for industrial application,and the contents of butadiene,dimethyl ether and methanol contained in alkylate feedstock after treatment are reduced to 50 ppm or less, which fully meet the requirements of the feed. At the same time,the isomerization rate of 1-butene isomerized to 2- butene is higher than 70%,butene yield higher than 98%.
