The present invention relates to a catalytic formulation used in the hydroprocessing of light and middle oil fractions, preferably in hydrodesulfurization and hydrodenitrogenation reactions to obtain diesel with ultra low sulfur content less than or equal to 15 ppm in weight. The catalytic formulation, object of the present invention, consists of at least one metal of Group VI B and at least one metal of Group VIII B and one element of Group V A of the periodic table deposited on a support based on surface modified alumina with an inorganic oxide of a metal of Group II A, IV A and/or IV B. And containing an impregnated organic compound containing at least one hydroxyl group and at least one carboxyl group and that can contain or not at least one sulfide group in its structure. The catalytic formulation, object of the present invention, allows processing of the oil fractions with initial and final boiling temperatures between 150 and 450° C., with initial nitrogen and sulfur content between 1 and 3% by weight and 200 to 600 ppm, respectively, reducing sulfur content to concentrations lower or equal to 15 ppm and nitrogen concentrations to lower than 1 ppm.
