摘要： A process to prepare new catalysts made from mixed metal oxides of transition metals, which involves the preparation of precursors and synthesis of these materials in oxide form from the preparation of a sol-gel formed from inorganic salts of these metals. An advance in the preparation of these catalysts made of mixed transition metal carbides and nitrides is proposed, providing an alternative way to the process of synthesis by solid-state reaction. The final product, in extruded form, has textural and mechanical properties superior to those obtained by the known techniques in the state of the art, and with better catalytic activity for hydrotreatment reactions.
