乙烯齐聚合锆系催化剂研究进展

Progress in studies on zirconium-based catalysts for ethylene oligomerization

综述了锆系催化体系的特点和研究进展,并对各种配体对催化活性和选择性的影响进行了分析比较。在乙烯齐聚合的催化体系中,不同有机铝对催化乙烯齐聚合的活性和选择性有较大的影响。在锆系催化剂中加入第三组分对乙烯齐聚物的相对分子质量分布有明显的调变作用。

The paper reviewed the worldwide for ethylene oligomerization, and analyzed research progresses and characteristics of zirconium-based catalysts the effects of different ligands on activity and selectivity of the catalysts. In the catalytic systems for ethylene oligomer/zation, different organo-aluminum compounds significantly influence the activity and selectivity of the catalysts. Adding third component into zirconium-base catalyst was beneficial to effectively adjusting the relative molecular weight distribution of the ethylene oligomers.
