  • Obtaining catalysts of MMoSand MMoSwith nanometric additive of SiO, synthesized in aqueous solution assisted by ultrasound
    Patent number: 8293205
    Abstract: A method for obtaining a promoted molybdenum sulfide catalyst and a promoted molybdenum sulfide added with a nanometric additive. The obtained catalyst exhibits an improved catalytic activity in hydrotreatment reactions, such as hydrodesulfurization, hydrodenitrogenation, and hydrogenation. The invention presents as an advantage, in addition to a low cost composition by their transition metals content, the activation of thiosalts precursor using an environmentally friendly atmosphere.
    Type: Grant
