摘要
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0.26kg/t。
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 percentage point lower than the results of the original catalyst A,the light liquid yield increases by 0.41 percentage point,propylene yield increases by 0.49 percentage point,RON of FCC gasoline improves by 1.3,and the unit consumption of catalyst decreases by 0.26 kg∕t.
