Title:
SUPPORTED POLYMETAL OLEFIN POLYMERIZATION CATALYST, PREPARATION METHOD AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/095678
Kind Code:
A1
Abstract:
The present invention relates to a supported polymetal olefin polymerization catalyst, comprising a porous support, and a magnesium-containing support component and 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 compound are used as raw materials, and the supporting of titanium is achieved while a composite support containing magnesium and non-magnesium components is formed in situ on the surface of the porous support. The present invention has the advantages of a simple preparation method, a low cost, a controllability of morphology and properties of the catalyst, etc., and comparing the provided catalyst with the same type of magnesium/titanium catalyst free of non-magnesium components, the catalytic performance such as polymerization activity, hydrogen regulation sensitivity and copolymerization performance are significantly improved.
