| titleOfInvention |
Novel supported double center hybrid polyethylene catalyst, process for preparing the same and use thereof |
| abstract |
The present invention relates to a carriered hybrid vanadium-chromium-based catalyst, characterized in the catalyst is carriered on a porous inorganic carrier and a V active site and an organic Cr active site are present on the porous inorganic carrier at the same time. The present invention further relates to a process for producing a carriered hybrid vanadium-chromium-based catalyst. The catalyst of the present invention can be used for producing ethylene homopolymers and ethylene/α-olefin copolymers. The hybrid vanadium-chromium-based catalyst can have high activity and produce polyethylene polymers having the properties of broad molecular weight distribution (Part of the products are bimodal distribution) and excellent α-olefin copolymerization characteristic. |
