摘　　要：裂解抽余C4中的丁烯和异丁烯等组分皆为高价值的化工原料,但抽余C4通常采用传统处理方式,难以发挥其价值。由于MTBE存在一定的污染性、乙醇汽油推广的不确定性及双碳战略下新能源的迅速发展的大背景中,本文对新规划项目的抽余C4提出了几种可行的工艺路线分析,以充分发挥抽余C4中各组分的高附加值。Butene and isobutene in C4 raffinate are important organic chemical raw materials,but traditional treatment process of C4 raffinate is not efficient.Due to the MTBE pollution,the uncertainty of alcohol-based gasoline promotion as well as the rapid development of new energy under the dual carbon strategy,this paper puts forward several feasible process routes analysis for the new planning project,in order to give full play to the high added value of each component in C4 raffinate.
