Patent number: 4428822Abstract: A method for maintaining a desired catalyst regeneration temperature in a fluid catalytic cracking unit operating with complete combustion of coke to carbon dioxide when the coke content of the spent catalyst supplied to the regeneration zone from the reaction zone is insufficient to maintain the temperature in the regeneration zone necessary for complete combustion of coke to carbon dioxide in which residual liquid hydrocarbon from the cracking reaction zone is introduced into contact with partially spent cracking catalyst at cracking reaction temperature effecting conversion of said residue to volatile reaction products and additional coke deposit on the spent catalyst in an amount sufficient to maintain the temperature in the regeneration zone necessary for complete combustion of coke to carbon dioxide and substantially complete removal of carbon from the catalyst.Type: GrantFiled: April 26, 1982Date of Patent: January 31, 1984Assignee: Texaco Inc.Inventor: Henry B. Jones

Patent number: 4324563Abstract: A hot raw gas stream, as produced by the partial oxidation of a solid carbonaceous fuel such as coal, is partially cooled and cleaned to remove entrained solid matter and slag. A novel gas--gas quench cooling and solids separation apparatus is employed. The apparatus comprises a closed cylindrical insulated vertical pressure vessel containing a lower quench chamber in communication with an upper solids separation chamber. The hot raw gas stream is cooled in the lower chamber to a temperature below the initial deformation temperature of the entrained slag by impingement and direct heat exchange with an oppositely directed coaxial stream of cooled, cleaned, and compressed recycle quench gas. The stream of cooled gas leaving the turbulent lower chamber passes up through a choke-ring into the comparatively calmer upper chamber counter-currently with solid slag droplets which separate out by gravity.Type: GrantFiled: July 13, 1979Date of Patent: April 13, 1982Assignee: Texaco Inc.Inventors: Henry B. Jones, Randlow Smith

Patent number: 4223843Abstract: An air distribution apparatus for delivering an oxygen-carrying gas such as air to a zone of spent catalyst in a regenerator for the purpose of combusting air with the spent catalyst in order to rejuvenate the catalyst. A header support assembly is adapted for mounting in a regenerator which receives the spent catalyst. A hollow header ring is mounted onto the header support assembly and includes a plurality of openings each having a nozzle mounted therein. Air is supplied to the header support assembly and thus to the hollow header ring at a pressure sufficiently high to effect a maximum desired pressure differential between header pressure and pressure in the zone of spent catalyst to cause maximum uniform air distribution. The nozzles mounted in the openings in the header ring decrease air velocity between nozzle inlet and nozzle outlet in order to provide for maximum uniform air distribution without destruction of the catalyst.Type: GrantFiled: March 16, 1978Date of Patent: September 23, 1980Assignee: Texaco Inc.Inventors: Randlow Smith, John P. MacLean, Dale Williams, Rich W. Barkley, Henry B. Jones

Patent number: 4051069Abstract: A process is described herein for regeneration of spent, coke contaminated fluidized cracking catalyst by burning coke therefrom with a molecular oxygen containing regeneration gas in a fluidized dense phase bed, and for burning substantially all carbon monoxide formed to carbon dioxide. A method is provided for balancing oxygen concentration across the cross-sectional area of the dense phase bed, as is a method for supplying additional oxygen above the dense phase bed for combustion of carbon monoxide. Additionally, a method is provided for transferring heat from a dilute phase back to the fluidized dense phase bed.Type: GrantFiled: May 7, 1976Date of Patent: September 27, 1977Assignee: Texaco Inc.Inventors: Dorrance P.

Patent number: 4028139Abstract: Various methods and a multiple thermocouple support assembly are disclosed. The support comprises a tube supported at both ends while extending across a vessel used in processing a fluid over a fixed bed of particulate solids, for example, such as a hydrotreating catalyst in fixed bed reactors, in which temperature measurements are required simultaneously at various defined locations in a horizontal plane across the bed. Features of the support include a particular means for mounting thermocouples in thermowells and particular means for securing the thermowells to the support tube, the thermocouples being pressed against the outer wall of each thermowell opposite to the support tube and the thermowells being spaced from each other and from the support tube for obtaining maximum heat conduction from the fluid or fixed bed of particulate solids with a minimum of heat conduction from the thermowell support tube.Type: GrantFiled: December 4, 1975Date of Patent: June 7, 1977Assignee: Texaco Inc.Inventors: Randlow Smith, Henry B. Jones, Adrianus C. Jobsis, Hugh C. Deloney
