重油高效转化FCC催化剂的工业应用

针对中国石油呼和浩特石化公司2.8 Mt/a催化裂化装置研究开发了一种新型重油高效转化催化剂B。在催化裂化装置的工业应用结果表明，与装置原催化剂A相比，使用催化剂B后，在原料性质变重变差和回炼油浆的情况下，生焦量仍降低0.22百分点，轻质液体收率增加0.41百分点，丙烯收率（对原料）提高0.49百分点，汽油研究法辛烷值增加1.3个单位，催化剂单耗降低0.26 kg/t。

COMMERCIAL APPLICATION OF HIGH EFFICIENT HEAVY OIL CONVERSION FCC CATALYST

A new high efficient heavy oil conversion catalyst B was developed and commercialized for a RFCC unit with a capacity of 2.8 Mt/a in Petrochina Hohhot Petrochemical Company. The commercial application results show that though the worse quality feed was used and the slurry was back recycled, the coke yield is 0.22% lower than the results of the original catalyst A, the light liquid yield increases by 0.41%, propylene yield increases by 0.49%, RON of FCC gasoline improves by 1.3, and the unit consumption of catalyst decreases by 0.26 kg/t.
