Abstract
A two-stage hydrotreating process comprises the steps of (1) contacting a liquid hydrocarbon-containing feed stream, which contains nickel, vanadium and Ramsbottom carbon residue, with hydrogen and a solid inorganic refractory material (preferably alumina) for at least partial removal of Ni and V, and then (2) hydrovisbreaking the intermediate product stream from step (1). Preferably, step (2) is carried out in the presence of at least one decomposable compound of a metal, preferably a molybdenum dithiophosphate.
