摘要
Evaluation of hydrocracking catalyst CHC-1 showed superior qualities ofcatalyst CMC-1. When it was used for hydrocracking reaction, the yield of middle distillates (jetfuel and diesel fuel) can reach more than 71 m%. When it was used for medium-pressurehydro-upgrading of Daqing FCC diesel fuel, diesel density was decreased by 0.0284―0.0365 g/cm^3(20℃). Cetane number increased by 7.8―10.5 and the contents of sulphur and nitrogen wereremarkably reduced. The storage stability of the upgraded diesel was improved.
