双金属中心双峰聚乙烯催化剂研究进展
Research progress of bimetallic catalysts for bimodal polyethylene synthesis
摘要
Abstract
Bimodal polyethylene are widely used to produce high performance pipes, such as PE100 and PE100RC, and shows increasing importance in polyethylene market because of their excellent mechanical and processing properties. Nowadays, commercialized bimodal polyethylene is synthesized primarily in tandem-reactor process, which needs high energy consumption and capital investment in equipment, beside, the technology is under monopoly of foreign companies. By contrast, bimodal polyethylene synthesis using bimetallic catalyst in single reactor process is becoming research hotspot in domestic and abroad, because this process is more environment friendly and needs much lower cost in equipment investment and operation. Recent work in this group on Cr-based bimetallic catalysts is reviewed. Development on other bimetallic catalysts is also introduced and future trend is prospected.关键词
