Abstract
The present invention relates to the preparation of catalysts used in the hydrodesulfurization of fossil fuels and proposes a method for preparing thermally stable, low-cost catalysts for the hydrodesulfurization of petrol and diesel, based on highly active CoMo and NiMo. The catalyst for the hydroprocessing of gasoil or petrol in the present invention comprises a precursor which consists of chemical compounds obtained from organic acids and metal salts, and a support containing an ultra-stable Y-type zeolite useful in the hydroprocessing of heavy gas oil and/or light cyclic gas oil with high conversion rates.
