A method for converting a hydrocarbonaceous feedstock to a lower boiling product is described which comprises suspending metal-impregnated carbonaceous particles in a reaction zone including hydrogen and the hydrocarbonaceous feedstock at hydrocracking conditions. The metal impregnated on the particles may be sulfided in the reaction zone. The impregnated particles are shown to be surprisingly selective catalysts, and anomalous ranges of particle size and concentration are identified. Methods for preparing the particles are additionally presented.

[ We claim as our invention:] [1.] A method for converting a hydrocarbonaceous feedstock to a product having a boiling point of lower temperature, as compared to the boiling point of the feedstock, which comprises:suspending metal-impregnated carbonaceous particles which are composed essentially of impregnated metals on carbon black sufficiently oxidized so as to be wetted by contact with water, which have an effective suspended particle size of about 0.01 to about 50 microns, and which physically support a sulfide of a water-soluble metal compound including a sulfidable metal selected from the group consisting of molybdenum, cobalt, nickel, iron, vanadium, tungsten and mixtures thereof, in a reaction zone which includes hydrogen and a hydrocarbonaceous feedstock so as to create a dispersion;maintaining conditions in the reaction zone which are effective to convert the feedstock to a product having a boiling point of lower temperature, as compared to the boiling point of the feedstock; andrecovering the lower boiling point product.
