摘要
介绍了LDO-75重油裂化催化剂在中国石油大连石化公司年产3.5 Mt重油催化裂化装置的工业应用。结果表明,LDO-75催化剂达到系统总藏量50%后,装置催化剂单耗由1.34 kg·t^(-1)降至1.04 kg·t^(-1),干气和油浆收率分别降低0.03%和1.36%,液化气收率增加1.19%,总液收提高1.42%。
The commercial application of LDO-75 catalyst for residue fluid catalytic cracking in 3.5Mr · a^-1 RFCC unit of PetroChina Dalian Petrochemical Company was introduced. The results showed that in comparison with the original catalyst, the consumption of LDO-75 catalyst decreased from 1.34 kg · t^-1 to 1.04 kg · t^-1 while LDO-75 catalyst loading reached 50% of the total catalysts; the yield of slurry and dry gas decreased by 0.03% and 1.36% respectively, LPG yield and the total liquid yield increased by 1.19% and 1.42%.
