  • Silica-promoted hydrofining catalyst and process
    Patent number: 4139493
    Abstract: Highly active hydrofining catalysts are prepared by ion exchanging a silica-alumina hydrogel with an ammoniacal solution of a cobalt and/or nickel compound, and thereafter compositing the undried product with an alumina hydrogel and a molybdenum component, followed by drying and calcining. The resulting catalysts are particularly active for the denitrogenation of mineral oil feedstocks.

  • Hydrotreating process and catalyst
    Patent number: 4138326
    Abstract: A catalyst comprising (1) a subgroup of a certain class of nickel and/or cobalt-substituted semicrystalline aluminosilicates which are synthetic and which are predominantly ordered in two directions (laminar clay-like materials); (2) tungsten in the form of its oxide and/or sulfide; and (3) a crystalline zeolite which has an alpha value of at least 20, which is in particulate form, and which is dispersed through the layered aluminosilicate; and processes using this catalyst.
