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&#xb0; 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.

Procedure for obtaining a catalytic formulation for the production of ultra low sulfur diesel, obtained product and application thereof

A hydrocracking catalyst having a support of a composite of mesoporous materials, molecular sieves and alumina, is used in the last bed of a multi-bed system for treating heavy crude oils and residues and is designed to increase the production of intermediate distillates having boiling points in a temperature range of 204&#xb0; C. to 538&#xb0; C., decrease the production of the heavy fraction (&#x3e;538&#xb0; C.), and increase the production of gasoline fraction (&#x3c;204&#xb0; C.). The feedstock to be processed in the last bed contains low amounts of metals and is lighter than the feedstock that is fed to the first catalytic bed.
