摘要
芳烃/脂肪烃分离是石油化工中重要的分离过程,渗透汽化膜分离技术是现有高能耗芳烃/脂肪烃分离过程的潜在技术。以调整石脑油的芳烃含量,生产"低苯汽油"或低芳烃含量的优质乙烯裂解原料为背景,论述了芳烃/脂肪烃混合物的渗透汽化分离膜的研究进展。
Separation of aromatic/aliphatic is important in petrochemical industry, and pervaporation is a potential alternative of the conventional energy-intensive technologies. Removing aromatics from naphtha by pervaporation can be used to produce ＇non-benzene＇ gasoline and low-aromatic feedstock in ethylene production plant. The recent progress in pervaporation membrane for multi-component aromatic/aliphatic separation was reviewed
