Abstract: A process for the production of aromatic hydrocarbons. The process involves heating gas oil while under pressure, and maintaining the gas oil at temperature and pressure to break the substantially aliphatic chains from the gas oil core structure of two or more aromatic rings, as well as to break the aliphatic chains to smaller molecules. The process yields products which include lighter aliphatic material, as well as aromatic hydrocarbons.

Abstract: This invention relates to a process for upgrading a hydrocarbonaceous material to a product having a lower boiling point than the initial boiling point of said hydrocarbonaceous material and/or a higher boiling point than the final boiling point of said hydrocarbonaceous material, the process comprising heating a feed composition comprising said hydrocarbonaceous material in an enclosed space in the absence of externally supplied water or hydrogen at a temperature in the range of about 750.degree. F. to about 1300.degree. F. and a pressure sufficient to maintain the specific gravity of the contents of said enclosed space in the range of about 0.05 to about 1.5 for an effective period of time to yield said product, said feed composition being characterized by the absence of aromatic compounds with boiling points at atmospheric pressure below about 350.degree. F.

Abstract: A process for making a light hydrocarbonaceous liquid in a delayed coker comprising:(A) providing a hydrocarbonaceous feed to the coke drum and heating the feed to a temperature of about 800.degree. F. to about 1200.degree. F. to provide an intermediate product; and(B) introducing said intermediate product into the coke drum, operating the coke drum to convert the intermediate product to a final comprising light liquid and coke, and separating the light liquid from the coke;step (A) being conducted in combination with either step (A) (i) or step (A) (ii);Step (A) (i) comprising maintaining the feed during step (A) in an enclosed space and subjecting the feed to a pressure that is at least about 500 psig and is sufficient to maintain the specific gravity of the contents of the enclosed space at least about 0.

Abstract: This invention provides for a process for separating extractable organic material from a feed composition comprising an oil-in-water emulsion comprising a continuous aqueous phase, a discontinuous organic liquid phase comprising said extractable organic material, and solids dispersed in said emulsion, the process comprising the steps of:(I) mixing said feed composition with sufficient shear to convert said feed composition to a water-in-oil emulsion; and(II) contacting said water-in-oil emulsion with at least one organic solvent, said organic solvent being capable of forming with said emulsion a system comprising at least two phases and being capable of dissolving at least about ten parts of said extractable organic material per million parts of said organic solvent at the temperature wherein at least about 50% by weight of said solvent boils at atmospheric pressure; forming a system comprising at least two phases, one of said phases being an emulsion phase comprising said emulsion and the other of said phase

Abstract: A technique for measuring the coefficient of thermal expansion of calcined petroleum coke. This technique involves pressing a pellet of calcined coke to determine the coefficient of thermal expansion. It has the advantage of eliminating the graphitization and machining steps resulting in reduced manpower and turnaround time and requires less sample which allows CTE determination of laboratory scale cokers. Results show good correlation between this technique and traditional extrusion techniques.

Abstract: A process for upgrading heavy hydrocarbons in an emulsion through dense phase processing. The process involves subjecting a feed of oil in an immiscible solvent emulsion to supercritical conditions to facilitate separation of the heavy hydrocarbons into light hydrocarbons with greater value and more uses.

Abstract: This invention relates to a process for upgrading a hydrocarbonaceous material having an initial boiling point of at least about 625.degree. F. to a product having a lower boiling point than the initial boiling point of said hydrocarbonaceous material and/or a higher boiling point than the final boiling point of said hydrocarbonaceous material, the process comprising heating a mixture comprising said hydrocarbonaceous material and at least one organic solvent in an enclosed space in the absence of externally supplied water or hydrogen at a temperature in the range of about 750.degree. F. to about 1300.degree. F. and a pressure in excess of about 1200 psig for an effective period of time to yield said product, said pressure being sufficient to maintain the specific gravity of the contents of said enclosed space in the range of about 0.05 to about 1.

Abstract: A process is disclosed for separating an organic material from a composition comprising said organic material intermixed with particulate solids, the process comprising advancing a light hydrocarbon fluid through said particulate solids at an effective rate to drive at least some of said organic material from said particulate solids, adding water to said composition containing particulate solids and residual organic material to produce a second composition, and adding an oxidizing agent to said second composition in an amount sufficient to remove substantially all of the residual organic material.
