Study on Ethylene Polymerization Catalyst Prepared from Clay Minerals Ⅱ.Catalyst Prepared by Supporting MgCl_2/THF/TiCl_4 on Palygoskite

Rong Junfeng,Jing Zhenhua,Hong Xiaoyu (Research Institute of Petroleum Processing,Beijing 100083,China)  
High surface area palygorskite was adopted as support of MgCl_2/THF/TiCl_4 high efficiency catalyst.Structure,property,and preparation of catalyst were studied systematically.Activity of the catalysts increased with increase of clay calcination temperature.But over-calcination will lead to collapse of clay structure and decreasing activity of catalyst.Kinetic behavior of the resulted catalyst was also studied.
