国产钛系BCH催化剂在淤浆法HDPE装置上的应用

APPLICATION OF BCH TITANIUM CATALYST IN HIGH DENSITY POLYETHYLENE UNIT

淤浆法生产高密度聚乙烯（ＨＤＰＥ）所使用的主催化剂为钛系高效催化剂，大庆石油化工总厂ＨＤＰＥ装置通过对国产ＢＣＨ催化剂的小聚合评价及工业化大批量使用，结果表明：ＢＣＨ催化剂综合性能指标好，催化剂活性高，氢调敏感性好，对产品的质量指标有优化和改善的显著效果，催化剂耗量较进口催化剂低。使用该催化剂有利于提高ＨＤＰＥ装置的生产负荷，提高单位时间的产量和产值。大庆石油化工总厂１４万ｔ／ａＨＤＰＥ装置年增产量可达６０００ｔ。

A BCH titanium catalyst manufactured in china has replaced the original imported catalyst in the high density polyethylene unit in Daqing Petrochemical Works. The commercial application showed that BCH catalyst had the advantages of high activity, good hydrogen sensitivity and low catalyst consumption as well as product quality improvement.
