Abstract

A process for the hydrogenation of heavy oils, residual oils, waste oils, used oils, shell oils, and tar sand oils by hydrogenating a slurry of the oil at a partial hydrogen pressure of 50-300 bar, a temperature of 250.degree.-500.degree. C., a space velocity of 0.1-5 T/m.sup.3 h, and a gas/liquid ratio of 100-10000 Nm.sup.3/ T, wherein the additive comprises two different grain size portions, a fine grain portion having a grain size of 90 microns or less and a coarse grain portion having a grain size of 100-1000 microns.
