摘　　要：2020年我国甲基叔丁基醚(MTBE)将不再允许作为汽油调和组分,MTBE装置急需研究转产方案。针对以上问题,分析了MTBE装置的技术现状及发展趋势,并提出了相应的解决方案。建设MTBE裂解制纯异丁烯装置,发展以纯异丁烯为主的下游产品;将原有MTBE装置略加改造转产乙基叔丁基醚;采用间接烷基化工艺转产高辛烷值的异辛烷烷基化油或高碳醇。By 2020,methyl tert-butyl ether(MTBE)will no longer be allowed as a gasoline blending component in China,and it is urgent for domestic MTBE plants to study on conversion plans.In view of the above problem,the technical status and development trend of the MTBE devices is analyzed,and corresponding program suggestions are proposed.It is proposed to build a MTBE cracking unit to produce pure isobutylene and develop downstream products mainly based on pure isobutylene;or slightly transform the original MTBE unit to ETBE;or use an indirect alkylation process to convert high-octane isooctane alkylation oil or higher alcohol.
