Heavy or refractory oils are hydroprocessed in the presence of added water and added hydrogen sulfide with or without a slurry catalyst comprising molybdenum sulfide. The water and hydrogen sulfide may originate from the catalyst preparation procedure.
1. A hydroprocess comprising introducing feed oil, hydrogen, water, hydrogen sulfide and hydrogenation catalyst to a hydroprocessing zone, the weight ratio of water to oil being between 0.005 and 0.25, the partial pressure of hydrogen sulfide being between 20 and 400 psi, the hydrogen partial pressure being between 350 and 4500 psi, the temperature being between 650° and 1000° F., said water being at least partially in the vapor phase, said hydrogenation catalyst comprising sulfided molybdenum which is present in said hydroprocess in the molybdenum as me...
