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°-500°C., a space velocity of 0.1-5 T/m3h, and a gas/liquid ratio of 100-10000 Nm3

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°-500°C., a space velocity of 0.1-5 T/m3h, and a gas/liquid ratio of 100-10000 Nm3/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.

A process for the hydrogenation of heavy oils, residual oils, waste oils, shale oils, tar sand oils, and mixtures thereof, comprising the steps of: (i) contacting said oil with 0.5-15 wt.% of an additive to form a slurry, said additive being selected from the group consisting of red mud, iron oxides

A process for the hydrogenation of heavy oils, residual oils, waste oils, shale oils, tar sand oils, and mixtures thereof, comprising the steps of: (i) contacting said oil with 0.5-15 wt.% of an additive to form a slurry, said additive being selected from the group consisting of red mud, iron oxides, iron ores, hard coals, lignites, cokes from hard coals, lignites impregnated with heavy metal salts, carbon black, soots from gasifiers, cokes produced from hydrogenation and virgin residues; and (ii) hydrogenating said slurry with hydrogen at a partial hydrogen pressure of 50-300 bar, a temperature of 250°-500°C., a space velocity of 0.1-5 T/m3h, and a gas/liquid ratio of 100-10,000 Nm3/T, wherein said additive comprises particles of at least two particle size fractions having a total particle size distribution between 0.1 and 2,000 microns, and wherein 10-40 wt.% of said particles have a particle size greater than 1,000 microns, said mixture of fractions not being represented by a straight line when its accumulative weight versus particle size, which is plotted on log (-log) versus log graph paper has a correlation coefficient less than 0.96 as determined from the equation: [Figure] wherein n is the number of experimental points, y is ln and x is ln (dp).
