重油催化裂化催化剂的发展
摘要:阐述了近年来我国重油催化裂化催化剂的发展状况。近年来,重油的催化裂化发展很快,新型的重油催化裂化催化剂不断应用于工业中:我国重油催化裂化催化剂在性能上有很大突破:其重油裂化能力高,抗重金属污染,并且干气和焦炭产率低。催化剂的新品种也在不断推出,我国的稀土Y型分子筛、超稳Y型分子筛和稀土1氢Y分子筛催化裂化催化剂的品种在不断更新换代。工业应用结果表明,USY分子筛重油催化裂化催化剂具有高的水热稳定性,低的焦炭选择性,以及较好的抗重金属污染能力。我国研究开发抗重金属污染的催化裂化钝化剂已应用于工业中,而且效果令人满意:,MGG,ARGG,MIO,HCC等几种典型重油催化裂化工艺所用的催化剂具有世界水平。此外,Orbit系列重油催化裂化催化剂的工业实践表明,该系列催化剂性能很好,可以满足不同装置的需要。
