混合碳四馏分中异丁烯选择性齐聚研究进展

Study on selective oligomerization of isobutylene in mixed C fractions

介绍了异丁烯齐聚反应机理和异丁烯齐聚反应产物的利用,重点介绍了可以替代混合C4馏分中异丁烯醚化生产MTBE的工艺、异丁烯选择性齐聚反应不同类型催化剂的性能比较等研究现状,从经济、技术和发展等方面对混合C4馏分中异丁烯选择性齐聚提出了建议。

The reaction mechanism of isobutylene oligomerization and the utilization of oligomeric products are introduced,with emphasis on the process that can replace the etherification process in which isobutylene in mixed C4 fractions is etherified to produce MTBE,and the comparison of the performance of different catalysts for selective oligomerization of isobutylene.The suggestions about selective oligomerization of isobutylene in mixed C4 fractions are given from economy,technology and development aspects.
