乙烯齐聚合成α-烯烃用催化剂研究进展

Progress on Research of Catalysts for Ethylene Oligomerizafion to α-Olefins

综述了近年来国内外乙烯齐聚用催化剂研究进展。催化剂主要有烷基铝系、钛系、镍系、铁系、铬系、锆系等。其中镍系催化剂具有活性高、选择性好、产品分布可调、反应条件温和等优良性能。铬系催化剂则可以高选择性的合成1-己烯和1-辛烯。

Progress on developing aluminum- , titanium- , nickel - , iron - , chromium - , and zirconium - based catalysts for ethylene oligomerization was reviewed. Nickel - based catalysts had excellent performances such as high catalytic activity, high selectivity, easily - controlled oligomers distribution and moderate reaction conditions. Chromium - based catalysts were used to produce 1 - hexene and 1 - octene with high selectivities. Key Words catalyst, ethylene, oligomerization, a - olefin, hexene, octene
