高效重油转化催化裂化催化剂的工业应用

摘要

A new high efficient heavy oil conversion catalyst A was developed and commercialized for a RFCC unit with a capacity of 3.5 Mt?a. The lab results showed that the slurry and coke yield reduced;the total liquid yield increased slightly and the propylene yield increased significantly. The commercial application results show that compared with the results of the original catalyst,using the feed with same properties,the metal content on the equilibrium catalyst decreases,propylene yield increases by 1.07 percentage points,slurry yield lowers by 2.91 percentage points,RON of FCC gasoline increases by 0.59,the NOx concentration at CO incineration flue gas furnace outlet decreases slightly.%针对南方某大型炼油厂3.5 Mt？a 催化裂化装置，研究开发了一种新型高效重油转化催化剂 A。实验室评价结果表明，使用该催化剂后油浆产率和焦炭产率降低，总液体收率略有提高，丙烯收率大幅增加。催化剂 A 在该炼油厂催化裂化装置工业应用的结果表明，与原催化剂相比，使用重油转换催化剂 A 后，在原料性质基本相当的情况下，平衡剂金属含量明显降低，丙烯收率提高1.07百分点，油浆产率降低2.91百分点，汽油研究法辛烷值增大0.59个单位，CO 焚烧炉出口烟气 NOx 浓度略有降低。
