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.
