雪佛龙-菲利浦化工公司(CPC)已经对一种新的茂金属催化剂进行了首次工业化生产,据称,该催化剂的价格比起过去使用的催化剂来大大降低了。该公司的总裁兼首席执行官JimGallogly说,这种用在聚乙烯生产中的新催化剂与以前的茂金属催化剂具有相同的产率,生产出的树脂也具有相似的性质。催化剂的高成本一直是用茂金属催化剂生产聚乙烯树脂的一大难题。“我们非常兴奋,因为新的催化剂改变了成本结构。”菲利浦公司在两年前推出了茂金属聚乙烯产品,商品名为mPact。这些催化剂使菲利浦公司得以改造泥环反应器来生产中密度和线性低密度聚乙烯产品,再作一些小变动即可生产高密度聚乙烯。
Chevron-Philips Chemical Company (CPC) has already made the first industrialization of a new metallocene catalyst, and it is said that the price of the catalyst is greatly reduced compared with the catalyst used in the past. Jim Gallogly, the company’s president and chief executive officer, said that the new catalyst used in polyethylene production has the same yield as previous metallocene catalysts and that the resulting resin has similar properties. The high cost of catalysts has been a major problem in the production of polyethylene resins using metallocene catalysts. “We are very excited because the new catalyst has changed the cost structure.” Two years ago, Phillips introduced a metallocene polyethylene product under the trade name mPact. These catalysts enabled Phillips to transform mud loop reactors to produce medium density and linear low density polyethylene products, and then make small changes to produce high density polyethylene.
