There is disclosed a process for the hydrodemetallization of a heavy hydrocarbon stream containing asphaltenes and a substantial amount of metals. The process comprises contacting the stream in a reaction zone under suitable conditions and in the presence of hydrogen with a catalyst comprising one or more transition metals on a porous glass support having specified physical properties. Sutiable transition metals are those of Group VIB and Group VIII of the Periodic Table of Elements. |
