【Abstract】 Of all the methods of preparing linear alpha olefins by ethylene oligomerization, Gulf, Ethyl and SHOP processes are the most mature. But all the processes are carried out under high pressure and catalysis by homogeneous oligomerization. Their reaction conditions are harsh and operations are difficult. Recently there is a trend that oligomerization carries out under medium pressure by means of new catalysts. This paper reviews the development of the homogeneous and heterogeneous catalysts for ethylene oligomerization, and it is pointed that shape selective zeolite will be one of the most prospective heterogeneous catalysts for ethylene oligomerization.更多还原
