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 fluid is an aqueous solution obtained by adding to water a metal in Group VIB of the Periodic Table, a phosphorus compound, a hydroxycarboxylic acid, and hydrogen 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 metal to the hydrogen peroxide is from 1/0.03 to 1/1. The catalyst produced using this fluid has excellent desulfurization activity.

On produit ce catalyseur d'hydrodésulfuration contenant un métal du groupe VI B du Tableau périodique et du phosphore, en mettant en contact un support comportant un oxyde inorganique poreux avec un liquide contenant des ingrédients destinés à ce support. Le liquide est une solution aqueuse que l'obtient en ajoutant à de l'eau un métal du groupe VI B du Tableau périodique, un composé phosphoré, un acide hydroxycarboxylique et du peroxyde d'hydrogène. Dans ce liquide, le rapport molaire métal du groupe VI B/peroxyde d'hydrogène est compris entre 1/0,03 et 1/1. Le catalyseur produit grâce à ce liquide fait montre de remarquables propriétés en matière d'hydrodésulfuration.
