Abstract: Supported catalysts for use in hydrocarbons hydrotreatments are made by shaping catalyst carrier, with or without catalyst precursors, into balls, calcining the balls at 300.degree.-1000.degree. C., and crushing the calcined balls to particles whose average size is 0.2-0.8 times the average diameter of the balls. When the precursors are not present during the manufacture, they are added thereafter.
