  • OBTENTION OF LOW LOADING CATALYSTS FOR DEEP HYDROCARBONS HYDRODESULFURIZATION BASED OF CoMoS, WITH NiMoS HYDRODENITROGENANT ADDITIVE, SUPPORTED ON THREE-DIMENSIONAL NANOSTRUCTURED MESOPOROUS MATERIALS
    Publication number: 20150182952
    Abstract: The present invention shows a synthesis method for a highly dispersed supported catalyst over a KIT-6 type nanostructured mesoporous oxide with elements from Groups IIIA or IVA, or IVB. The method includes the synthesis of the support, the incorporation of CoMo and NiMo active phases through impregnation to pore volume, assisted by ultrasound, calcination at controlled conditions in order to obtain a phase of hydrated trioxide molybdenum or molybdic acid, which facilitates the subsequent sulfihydration and the mechanical mixing of a CoMoS/support with a hydrodenitrogenant NiMoS/support additive. The obtained catalysts exhibit a catalytic activity mainly in reactions of hydrotreatment, hydrodesulfurization, and hydrodenitrogenation.

  • 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.
