摘要　当前开发的烯烃/链烷烃分离技术有物理吸收法、化学吸收法、吸收分离法、萃取蒸馏法及膜分离法。其中最有发展前途的是利用π-配合作用的化学吸收法，现已有工业化装置。将蒸馏与吸附相结合的复合分离技术，是烯烃/链烷烃分离技术的发展方向之一。

Abstract　A number of olefin/paraffin separation technologies have been developed today. They include physical absorption, chemical absorption, absorption separation, extractive distillation and membrane separation. The most promising appears to chemical absorption by π-complexation. There are already some commercialized plants. One of the developing trends for olefin/paraffin separation is the composite separation technology combining distillation with absorption.

Key words　olefin/paraffin separation, chemical absorption, π-complexation, absorption separation, membrane separation, extractive distillation
