CATALYSTS SUPPORTED FOR THE PRODUCTION OF ULTRA-LIGHT SULFUR FUELS.

摘要

The present invention pertains to the field for preparing catalysts used for the hydrodesulphurization of fossil fuels, providing a method for preparing thermally stable and affordable catalysts for the hydrodesulphurization of gasoline and fuel, based on highly active CoMo and NiMo. The catalyst for the hydrotreatment of diesel fuel or gasoline of the present invention comprises a precursor that consists of chemical compounds obtained from organic acids and metallic salts, and a support that contains a zeolite of the ultra-stable type, useful in the hydrotreatment of heavy diesel fuel and/or light cyclic diesel fuel with high conversions.
