1. A slurry hydrocracking process using spent hydroprocessing catalyst comprising:
- obtaining the spent hydroprocessing catalyst from a hydroprocessing zone;
reducing the size of the spent hydroprocessing catalyst; and
introducing a heavy hydrocarbon feed and a hydrogen stream into a slurry hydrocracking zone in the presence of the reduced size spent hydroprocessing catalyst under slurry hydrocracking conditions to form a slurry hydrocracking effluent.

Abstract
A slurry hydrocracking process using spent hydroprocessing catalyst is described. The process includes obtaining the spent hydroprocessing catalyst from a hydroprocessing zone; reducing the size of the spent hydroprocessing catalyst; and introducing a heavy hydrocarbon feed and a hydrogen stream into a slurry hydrocracking zone in the presence of the reduced size spent hydroprocessing catalyst under slurry hydrocracking conditions to form a slurry hydrocracking effluent.
