Oct 30, 1992

Appl. No.:

7/969543

Inventors:

Lillian A. Rankel - Princeton NJ

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C10G 4504
C10G 4502

US Classification:

208251H

Abstract:

A process for treating heavy oil by contacting the oil with hydrogen in a reactor containing an activated carbon catalyst having a specified range of Alpha value, and average pore diameter, and pore distribution, to reduce the content of nickel and vanadium in the feedstock and to achieve conversion of the carbon residue for producing a lighter oil.

Appl. No.:

6/326257

Inventors:

Lillian A. Rankel - Princeton NJ

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

C10G 2902
C10G 4502

US Classification:

208211

Abstract:

The present invention relates to a method for removing contaminants such as arsenic from a hydrocarbonaceous fluid which consists essentially of the crude, or a fraction thereof, obtained from oil shale, solid coal, or tar sands by non-catalytically heat treating the hydrocarbonaceous fluid at a temperature of from about 20. degree. F. to about 600. degree. F. in the presence of an aqueous solution containing an agent that would convert such contaminants into components soluble in the aqueous solution. Particularly suitable agents to be utilized in the above aqueous solution to remove contaminants such as arsenic are ammonium sulfide type compounds. The purified hydrocarbonaceous fluid may be subjected to a catalytic hydrotreating process.

Appl. No.:

7/668571

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C10G 5500
C10G 5700

US Classification:

208252

Abstract:

A catalytic cracking process for heavy metals and asphaltene containing feed is disclosed. A reactive sulfur compound, preferably H. sub. 2 S, is dissolved in the heavy feed and then kept at a temperature and for a time sufficient to at least partially decompose the metal containing compounds and also to reduce the molecular weight of the asphaltenes. Preferably a metal scavenging additive is added to the equilibrium catalyst. The additive will rapidly remove the thermal- and sulfur-treated metal containing compounds and prevent or minimize metals poisoning of the cracking catalyst. Sulfur induced cracking of heavy oil components reduces the viscosity of the heavy feed, and permits lower temperature to be used in the cracking reactor.

Appl. No.:

7/100868

Inventors:

Lillian A. Rankel - Princeton NJ

Assignee:

Mobil Oil Company - New York NY

International Classification:

C10G 5504

US Classification:

208 85

Abstract:

Disclosed is a method for accelerating the exchange of hydrogen between a hydrogen donor and a petroleum resid to be subjected to cracking, visbreaking, or coking. Acceleration is effected by incorporating an aqueous solution of ammoniun sulfide into the mixture of donor and resid and subjecting the mixture to a period of heat-soaking at an elevated temperature.

International Classification:

C10G 4508

US Classification:

208211

Abstract:

The nitrogen-containing and oxygen-containing contaminants of a mineral oil are converted to the corresponding sulfur compounds by contacting the oil with a fresh catalyst containing metals from Groups VB, VIB and VIII or a deactivated and metals contaminated hydrodesulfurization catalyst in the presence of hydrogen and hydrogen sulfide under conditions of elevated temperature and pressure.

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C10G 900

US Classification:

208106

Abstract:

A process for preparing a pipelineable oil from a heavy crude oil by thermally treating the oil in the absence of added hydrogen, and under sufficiently severe conditions to induce the formation of an upgraded, low viscosity oil phase and a liquid asphalt phase that contains dispersed coke. The reaction is conducted under pressure sufficient to retain in the reactor most of the normally liquid hydrocarbons, under which conditions the two phases are readily separated and recovered solely by gravity settling. The process is readily adapted to oil field use with skid mounted units. The severity is adjusted to provide sufficient asphalt which, when burned, furnishes the steam required for production of the heavy crude oil.

Appl. No.:

Inventors:

Lillian A. Rankel - Princeton NJ

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

C10C 300

US Classification:

208 45

Abstract:

A process is provided for preparing pipelineable syncrude and asphalt from a heavy crude oil. The syncrude has substantially less metals content and Conradson Carbon Residue than the precursor crude oil, and may be used as feed for catalytic cracking or as fuel oil. The asphalt is adaptable for paving. The process consists of air-blowing the crude, deasphalting the air-blown product, and thermally cracking the deasphalted oil to reduce its viscosity, in that order. The process is adaptable to on-site use in or near a heavy oil field, using skid-mounted equipment.

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

C10G 2904

US Classification:

208253

Abstract:

Hydrocarbon oils, particularly petroleum residua, are demetallized by contacting the oil first with an aqueous solution of a hypochlorite such as sodium hypochlorite or calcium hypochlorite and subsequently subjecting at least the oil fraction thereof to a solvent deasphalting step.
