摘　　要：在对甲基叔丁基醚(MTBE)及二异丁烯工艺的化学反应、热力学、动力学分析的基础上,讨论了甲基叔丁基醚装置工艺转产二异丁烯工艺的技术方案以及二异丁烯装置的操作控制和工艺指标。工业运行结果表明,以催化裂化装置混合C4为原料,异丁烯的转化率达到98%,二异丁烯在叠合产品中的质量分数为91%,相对于原料的产率为14.9%。理论分析显示,二异丁烯产率仍有提升空间。Through analyzing chemical reactions,thermodynamics and kinetics of methyl tert-butyl ether(MTBE)and diisobutylene production processes,the technical scheme for revamping MTBE production unit to diisobutylene production unit is explored,and the operation control and process parameters of diisobutylene unit are discussed.Commercial operation results show that the conversion of isobutylene can reach 98%and the content of diisobutylene in the oligomerization products is 91%,and the yield is 14.9%relative to the feedstock when mixed C4 from fluid catalytic cracking unit is used as feedstock.It is revealed from the theoretical analysis that the yield of diisobutylene still has room for improvement.
