Novel supported double-center composite polyethylene catalyst and preparation method and use thereof |
| abstract |
The present invention relates to a novel supported double-center composite polyethylene catalyst and preparation method and use thereof, characterized in that a vanadium supported active component is added on a common supported organic chromium-based polyethylene catalyst. The present invention relates to a preparation method of a novel supported double-center chromium and vanadium composite polyethylene catalyst. The catalyst of the present invention can be used to produce ethylene homopolymer, and ethylene/α-olefin copolymer. The chromium and vanadium composite catalyst has the characteristics of high activity, wide molecular weight distribution of products (a part of the products are in bimodal distribution), excellent α-olefin copolymerization performance and the like. |
