Abstract
Provided is a method for preparing a linear alpha olefin using a chromium-based catalyst, including the steps of: removing oxygen impurities by contacting an olefin with an oxygen adsorbent; injecting the olefin from which the oxygen impurities are removed; a chromium-based catalyst into a reactor; and oligomerizing the olefin in the reactor.
Claims15
A method for preparing a linear alpha olefin, the method comprising steps of:
- removing oxygen impurities by contacting an olefin with an oxygen adsorbent;
- injecting the olefin from which the oxygen impurities are removed, and a chromium-based catalyst into a reactor;
- oligomerizing the olefin in the reactor;
- and
- terminating the oligomerizing reaction by using a catalyst deactivator,
- wherein the step of removing the oxygen impurities is performed under a temperature of 50 to 100° C.
