A mixture of heavy hydrocarbons, hydrogen and fresh catalyst comprising metals from the groups Vb, VIb, VIIb or VIII is passed first in a furnace for a limited heating time and then in a reactor where recycled catalyst is also added; the recycled catalyst is used in the form of a suspension recovered by fractionation of the reaction product.
A process for hydrotreating an asphaltene-containing hydrocarbon oil charge stock, comprising the steps of: (a) admixing said hydrocarbon oil charge stock with hydrogen and fresh catalyst, said catalyst comprising at least one metal compound whose metal component is selected from groups Vb, VIb, VIIb and the iron group of group VIII, the amount of said metal compound, expressed as metal, relative to said hydrocarbon oil charge stock being from 20 to 500 ppm by weight; (b) passing the resultant mixture from step (a) through a heating zone comprising a hea...
