  • Catalytic dewaxing of hydrocarbon oils
    Patent number: 4229282
    Abstract: An improved process for catalytically dewaxing a hydrocarbon oil is disclosed. In this process the waxy oil is contacted in the presence of hydrogen with a dense zeolitic dewaxing catalyst associated with a nickel-tungsten hydrogenation component. The dewaxed oil has unexpectedly good stability and a low bromine number compared with prior-art processed oils. The process may be used to dewax crude oils, fuel oil fractions and lubricating oils.
    Type: Grant
    Filed: April 27, 1979
    Date of Patent: October 21, 1980
    Assignee: Mobil Oil Corporation
    Inventors: Alan W. Peters, Emmerson Bowes, Thomas R. Stein
  • Hydrodenitrogenation of demetallized residual oil
    Patent number: 4210525
    Abstract: Demetallized oils such as deasphalted or catalytically demetallized residua are upgraded as catalytic cracking feedstock by contact with a denitrogenation catalyst having at least 80 percent of its pore volume in pores less than 50 Angstroms in diameter.

  • Production of high V.I. lubricating oil stock
    Patent number: 4176050
    Abstract: Waxy distillate lubricating oil stocks suitable for the preparation, by conventional unit processes, of high V.I., low pour point lubricating oils, are advantageously catalytically dewaxed with macrocrystalline ZSM-5 (crystallites larger than 2 microns) preferably associated with a hydrogenation metal such as platinum or palladium.

  • Method of upgrading a Fischer-Tropsch light oil
    Patent number: 4126644
    Abstract: The product of Fischer-Tropsch synthesis is separated to recover a C.sub.5 -400.degree. F liquid fraction which is thereafter upgraded to a higher octane gasoline fraction and a low-pour, high diesel index fuel oil by a "dense phase" process using HZSM-5 and related zeolites as catalysts.

  • Conversion of coal-derived liquids with a crystalline aluminosilicate zeolite catalyst
    Patent number: 4105535
    Abstract: Solvent refined coal bottoms which are solid at room temperature are converted to distillable liquids by blending the bottoms with recycle solvent and contacting the mixture in the presence of hydrogen over Ni/ZSM-5 catalyst.

  • Method for upgrading a Fischer-Tropsch light oil
    Patent number: 4052477
    Abstract: The product of Fischer-Tropsch Synthesis is separated to recover a C.sub.5 -400.degree. F liquid fraction which is thereafter hydrogenated in order to saturate diolefins and contacted with a ZSM-5 type zeolite under conditions of elevated temperature and pressure so as to obtain gasoline of a higher octane rating. The contact with the ZSM-5 zeolite is preferably in the presence of added hydrogen.
