Residual oils containing metals and sulfur are demetallized and desulfurized by adding to the oil an aromatic solvent and contacting the mixtures in the presence of hydrogen with an alumina having an average pore size greater than about 220 Angstroms.

Hydrotreating petroleum heavy ends in aromatic solvents with large pore

Residual oils containing metals and sulfur are demetalized and desulfurized by adding to the oil an aromatic solvent and contacting the mixture in the presence of hydrogen with an alumina having dual pore size distribution in ranges of 90-200 Angstrom units and 1000-5000 Angstrom units.

Hydrotreating petroleum heavy ends in aromatic solvents with dual pore

A process for the demetalation of heavy petroleum residua is provided wherein said residua dispersed in a suitable solvent is contacted with a large pore solid sorbent whereby organomettalic compounds or complexes contained in said residua are selectively adsorbed by the large pore solid sorbent.

Adsorptive demetalation of heavy petroleum residua

A method for upgrading a high boiling hydrocarbon fraction by reducing the molecular weight of at least a portion of the waxy or non-waxy constituents of the fraction with a catalyst composed of a heat stable crystalline zeolite in a matrix comprising a degraded heat-sensitive crystalline zeolite.

Petroleum processing with low acidity catalyst

This invention provides an improved process for hydroconversion of a heavy hydrocarbon oil having a CCR content of 8-30 weight percent, which process involves contacting the heavy oil in a hydrovisbreaking zone containing a low acidity zeolite catalyst and recovering and fractionating the visbroken effluent to provide distillate products and a 1000.degree. F.+ fraction which has a Kinematic Viscosity between about 30,000-60,000 centistokes at 100.degree. F.

Hydrovisbreaking process

This invention provides a method for reducing the level of thiophenic sulfur compounds in a heavy carbonaceous oil feed which involves contacting the oil feed with a C.sub.1 -C.sub.4 alkanol in the presence of a non-acidic zeolite catalyst. The reaction equilibrium in the process favors the displacement of thiophene sulfur atoms by oxygen atoms.

Process for reducing thiophenic sulfur in heavy oil

A stabilized lubricating oil resistant to oxidation and sludge formation upon exposure to an oxidative environment is prepared without forming undesirable color bodies therein by the steps (1) contacting the lubricating oil stock with a small amount of added elemental sulfur of from about 0.05 to about 1.0 percent by weight at a contact temperature of from about 25.degree. C. to about 130.degree. C. and (2) contacting the product of step (1) with hydrogen in the presence of alumina impregnated with at least about 10 weight percent MoO.sub.3 and at least about 2.5 weight percent CoO to remove any unreacted added elemental sulfur therefrom. The impregnated alumina catalyst of step (2) must have at least 50 percent of the pores with a pore diameter of 50 Angstrom Units or more.

Process for manufacture of stabilized lubricating oil with elemental

A stabilized lubricating oil resistant to oxidation and sludge formation upon exposure to an oxidative environment is prepared without forming undesirable color bodies therein by contacting the lubricating oil stock with a small amount of elemental sulfur of from about 0.1 to about 0.5 percent by weight at a contact temperature of from about 25.degree.C to about 70.degree.C and, thereafter, removing any unreacted sulfur therefrom.
