摘　　要：混合C_4主要用于生产烷基化汽油和甲基叔丁基醚(MTBE),我国到2020年将全面禁用MTBE,C_4选择性叠合技术+1-丁烯分离工艺路线和C_4烷基化组合加工将是混合C_4今后发展的途径之一,该组合工艺既可以生产工业异辛烷作为汽油的调和组分,又能生产浓度(质量分数)为93%的1-丁烯,同时副产品C_4烷烃可以作为乙烯装置原料,将会产生较好的经济效益。Mixed C4 is mainly used to produce alkylated gasoline and MTBE.MTBE will be banned in China by 2020,so the combined process of C4 selective polymerization plus 1-butene separation and C4 alkylation is a good way to develop mixed C4 in the future.This combined process can produce not only the industrial isooctane as a blending component for gasoline but also the 1-butene with a concentration of 93%,while the by-product C4 alkane can be used as raw material for ethylene plant.Good economic benefit will be achieved.
