A hydrofining catalyst containing a metal in Group VIB of the Periodic Table and phosphorus is produced by contacting a support comprising a porous inorganic oxide with a fluid containing ingredients to be supported. The flu id is an aqueous solution obtained by adding to water a metal in Group VIB of t he Periodic Table, a phosphorus compound, a hydroxycarboxylic acid, and hydroge n peroxide. in the fluid, the molar ratio of the Group VIB metal to the hydroxycarboxylic acid is from 1/0.05 to 1/1, and that of the Group VIB meta l to the hydrogen peroxide is from 1/0.03 to 1/1. The catalyst produced using this fluid has excellent desulfurization activity.
