聚合催化剂的应用与市场状况

Application and Market Status of Polymerization Catalysts

聚合反应的催化剂主要包括单活性点催化剂、齐格勒-纳塔催化剂和菲利浦催化剂。单活性点催化剂是具有增长潜力的品种，以其催化合成的聚合物产品的消费量在伞球范围内都在增长。在西欧，70％-75％的聚乙烯生产装置采用齐格勒．纳塔催化剂生产，同时聚丙烯生产装置也主要是以该类催化剂生产，23％-25％的聚乙烯生产装置采用菲利浦催化剂生产。改进型齐格勒-纳塔催化剂可以比较容易地应用于现有生产工艺中，已在PP生产过程中占据稳同位置，预计今后的用量还会增长。

The main catalysts for polymerization are single-site catalysts, Ziegle-Natta catalysts and Phillips catalysts. Single-site catalysts are the ones of the growth opportunities, the ,narket for polymers ,nade with single-site catalyst is growing globally. In Western Europe, about 70% -75% of polyethylene production capacity uses a Ziegle-Natta catalyst, the 23% - 25% installed capacity is based on Phillips catalyst, polypropylene is produced mainly by Ziegle-Natta catalyst. Advanced Ziegle-Natta catalysts can be readily applied to existing processes,and they are more firmly established in polypropylene production, so their use should continue to grow.
