    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.

    Abstract: The present invention relates to a supported polymetal olefin polymerization catalyst, comprising a porous support, a magnesium-containing support component, a transition metal titanium component supported on the porous support, and further comprising at least one non-magnesium metal component supported on the porous support. Further provided is a preparation method and a use of the supported polymetal olefin polymerization catalyst. An efficient composite support supported polymetal Ziegler-Natta catalyst is provided in the present invention, wherein a porous support, a soluble magnesium compound, and a soluble non-magnesium metal compound are used as raw materials. The supporting of titanium is achieved while a composite support containing magnesium and non-magnesium metal components is formed in situ in the surface of the porous support. The present invention has the advantage of a simple preparation method, a low cost, a controllability of morphology, properties of the catalyst, etc. Comparing the provided catalyst with the same type of magnesium/titanium catalyst free of non-magnesium metal components, the catalytic performance such as polymerization activity, hydrogen regulation sensitivity and copolymerization performance are significantly improved.
