  • Demetalation, desulfurization, and decarbonization of petroleum oils by hydrotreatment in a dual bed system prior to cracking
    Patent number: 4447314
    Abstract: A process is described for hydrotreating residual oil fractions in an improved dual bed catalyst system comprising a first large-pore catalyst and a second small-pore catalyst in which at least the second catalyst and preferably both catalysts have a quadrulobal shape. Using cobalt and molybdenum composited on alumina as these catalysts, residua are demetalized, desulfurized, and reduced in carbon residue, whereby hitherto unusable residue can be hydroprocessed.
    Type: Grant

  • Hydrodewaxing catalyst performance
    Patent number: 4247388
    Abstract: A method is disclosed for the improvement of catalyst performance in catalytic hydrodewaxing of both petroleum and synthetic hydrocarbon feedstocks utilizing a special group of acidic crystalline aluminosilicate zeolites such as those of the ZSM-5 type which involves treatment of said zeolites in order to adjust their initially high alpha activity to within a range of 55-150 alpha prior to use as catalysts in a hydrodewaxing operation.
