MCI is a novel hydrotreating process for upgrading low quality diesel distillates, such as LCO from FCC and resid FCC. The hydrotreating conversion of MCI process is between conventional hydrotreating and middle pressure hydroupgrading or hydrocracking. It has the advantages of high diesel distillate yield with high cetane number. The main purpose of the MCI process is to perform hydrotreating reactions, such as HDS, HDN, as well as improve the product cetane number. The task of improving product cetane number is realized by utilizing a new type of catalyst under nearly the same operating conditions of conventional hydrotreating. The idea of this technology is to control the reaction to the step of ring opening without cracking, which keeps the high diesel yield with high cetane number. A large amount of experimental data shows that the MCI process is sophisticated from its catalyst activity, selectivity, stability and its process simplicity. In most cases, the MCI process can increase the product cetane number more than 10 units, and maintain the diesel distillate yields higher than 95wt%.
