Title
(EN) Preparation method and application of novel supported double-center composite polyethylene catalyst
(ZH) 一种负载型双中心复合聚乙烯催化剂的制备方法和应用
Abstract
(EN)
The invention relates to a preparation method and application of a novel supported double-center composite polyethylene catalyst. The catalyst is characterized in that: a supported vanadium active ingredient is additionally arranged on the normal supported organic chromium polyethylene catalyst. The invention relates to a preparation method of a novel supported double-center chromium and vanadium composite polyethylene catalyst. The catalyst provided by the invention can be used for producing ethylene homopolymer and ethylene and alpha-olefin copolymer. The chromium and vanadium composite catalyst has the characteristics of high activity, wide molecular weight distribution of products (a part of products are in bimodal distribution), superior alpha-olefin copolymerization performance and the like.
