ABSTRACT:
An improved process for removing metals from heavy oils and other hydrocarbon feed streams is disclosed. The process comprises combining water with the hydrocarbon feed stream at a liquid volume ratio of about 1:50 to about 1:1, and contacting the mixture under suitable demetallizing conditions with hydrogen gas and a catalyst composition comprising (a) AlPO.sub.4 and preferably (b) a Group VIB metal, more preferably molybdenum.
