PROCESS FOR THE CONVERSION OF HEAVY HYDROCARBON OILS INTO LIGHT HYDROCARBON OILS

摘要

PROCESS FOR THE CONVERSION OF HEAVY HYDROCARBON OILS INTO LIGHT HYDROCARBON OILS Heavy hydrocarbon oils are converted into light hydrocarbon oils by two-stage process wherein, in the first stage, a heavy hydrocarbon oil is subjected to thermal cracking conditions and, in the second stage, the product of the thermal cracking is subjected to a hydrotreatment in the presence of a specific catalyst having a large pore volume in pores with diameters of 200 - 400 .ANG.. The hydrotreatment is carried out so that the product oil may have a toluene insoluble content of 0.5 wt % or less.
