Title:

METHOD OF SEPARATING α-OLEFIN BY SIMULATED MOVING BED PROCESS

Document Type and Number:

WIPO Patent Application WO/2020/177235

Kind Code:

A1

Abstract:

The invention provides a method of separating α-olefin by means of the simulated moving bed process. The method comprises using coal-based Fischer-Tropsch synthetic oil as a raw material, and the carbon number N of the target olefin ranges from 9-18. The raw material is subjected to pretreatment, fraction cutting, separation of alkanes and alkenes, isomer separation and other processing steps to obtain a high-purity α-olefin product. Compared with the conventional rectification and extraction process, the product obtained by the method of the present invention has a higher purity, a higher yield, lower energy consumption and significantly reduced production cost.
