  • Preparation procedure for a zeolite type monometallic catalyst to obtain high octane gasolines through naphtha reforming process
    Patent number: 6689708
    Abstract: A process for preparing a reforming catalyst comprises incorporating a group IA alkali metal from an aqueous alkaline solution into a zeolitic material by means of ion exchange to form an alkali metal-modified zeolitic support material, which is dried, calcined and combined with an inorganic oxide. The combination is dried and calcined to form a stable inorganic oxide/zeolitic catalyst support which is impregnated with a Group VIII metal by ionic exchange to form an impregnated inorganic oxide/zeolitic catalyst support which is dried, calcined and reduced from a naphtha reforming catalyst.
    Type: Grant
    Filed: September 25, 2001
    Date of Patent: February 10, 2004
    Assignee: Instituto Mexicano del Petroleo
    Inventors: Jesus Manuel Bautista Barrera, Ma. de Lourdes Ramirez de Lara, Rene Zarate Ramos, Oscar H. Bermudez Mendizabal, Gabriela Espinosa Santamaria

  • Selective oxidation catalyst, preparation and use thereof
    Patent number: 6083473
    Abstract: A catalyst for selective oxidation of sulfur-containing compounds comprising a metal of Group VIIIA which forms an active metal oxide supported on a support comprising a laminar phyllosilicate, alone, or in combination with silica or alumina. Laminar phyllosilicate and silica impregnated with a metal of Group VIIIA which forms an active metal oxide that achieves a conversion in excess of 95 percent of hydrogen sulfide or acid gas selectively to elemental sulfur and water, respectively.
