Process for hydrogenation of heavy oil.

摘要

An improved process for hydrogenation of heavy oil is provided by the use of a mixed catalyst. In the process of the present invention, a mixture of a direct desulfurization catalyst and a waste FCC catalyst is used as the mixed catalyst. In accordance with the process of the present invention, a middle distillate fraction having a boiling point falling within the range of 171 to 343 DEG C can be obtained in high yield.
