The Application of ZR-Catalyst on Synthesis of Polyethylene in Chemical Engineering

Abstract

A novel catalyst (ZR--catalyst) is prepared in chemical engineering, ZR--catalyst was prepared in a 50L kettle，the repeating property of which is stable. The result of polymeration if a 1m3 kettle connected with a 16m3 kettle is the same as that of the laboratory’s activity，the ratio of pollen，and the property of the UHMWPE produced by ZR--catalyst were better than that of the catalyst prepared by grinding method. The molecular weight of UHMWPE prepared with ZR--catalyst is more than 4 million. Meanwhile，the particle is small，uniform and regular. The ratio of pollen of product can be improved by 10 percent
