JCEG-1DL增产汽油收率渣油催化裂化助剂的工业应用

Commercial application of JCEG-1DL residuefluid catalytic cracking promoter for increasing gasoline yield

介绍JCEG-1DL渣油催化裂化助剂在中国石油大连石化分公司3.5 Mt·a^(-1)催化裂化装置上的工业应用情况。结果表明,当JCEG-1DL助剂加入量达到系统藏量的7.5%时,与空白标定期相比,汽油收率增加3.50个百分点,油浆收率降低1.39个百分点,(焦炭+干气)收率基本保持不变。由此可见,采用JCEG-1DL增产汽油渣油催化裂化助剂,产品选择性好,汽油收率高,重油转化能力强。

The application results of JCEG-1DL additive in a 3.5 Mt·a^(-1)residuefluid catalytic cracking unit of PetroChina Dalian Petrochemical Company are described.When loading of JCEG-1DL promoter amounted to 7.5%of the catalyst inventory,gasoline yield increased by 3.50%and slurry oil yield decreased by 1.39%,and coke and dry gas yield remained unchanged,in comparison with the blank reference.JCEG-1DL promotereffectively enhancedselectivity to product,tgasolineyield heavy oil conversion.
