  • Patent number: 4426277
    Abstract: A fluid coking process is provided in which a carbonaceous feed is first coked in a dense fluidized bed first coking zone and the effluent of the dense bed is passed as a suspension through a transferline second coking zone. A major portion of the solids is separated from the effluent of the upper end of the transferline and passed to a third coking zone which is operated at a higher temperature than the other coking zones and in which the first and second coking zones are positioned.

  • Patent number: 4325815
    Abstract: An integrated catalytic fluid coking and gasification process is provided in which a portion of the coke produced in the coker is steam gasified to produce a hydrogen-containing gas and a catalytic partially gasified coke. Subsequently, a portion of the catalytic partially gasified coke is burned to provide heated partially gasified coke which is recycled to the gasification zone. A portion of the catalytic partially gasified coke is passed from the gasification zone to the coker to contact the coker vapor phase product comprising normally liquid hydrocarbons and to crack at least a portion of the normally liquid hydrocarbons. Optionally, solid fines recovered from the gaseous effluent of the gasification zone may be recycled to the carbonaceous chargestock of the coker.

  • Patent number: 4295956
    Abstract: A fluid coking process is provided in which the recycling of coke particles of less than about 44 microns in diameter to the coking reactor is minimized by passing the stream of coke withdrawn from the coking reactor to a vessel comprising a fluidized bed of solids separated into two zones. The coke withdrawn from the coker is passed into one zone where seed generation for the process is performed. Coke recycled to the coker is withdrawn from the second zone which is operated as an elutriation zone. The solid fines of less than 44 microns are removed overhead from the vessel with the gaseous effluent of the vessel. This improvement is particularly suitable for once-through fluid coking to minimize small fines being present in the coker liquid product.

  • Patent number: 4269696

  • Patent number: 4244805
    Abstract: The quantity and quality of liquids produced from solid coal can be enhanced by a process comprising a liquefaction zone and a pyrolysis reactor, preferably a fluid coking zone, wherein the heavy liquids obtained in the pyrolysis reactor, e.g., 1000.degree. F.+ materials having a Conradson Carbon content of at least 15 wt. % are recycled to the liquefaction zone, rather than to the pyrolysis reactor, for further treatment under hydrogenation conditions and, consequently, conversion of the heavy liquids to lower boiling liquids which may be removed from the pyrolysis reactor feed by distillation is achieved.

  • Patent number: 4235700
    Abstract: A low metals coke is produced in a two-stage coking process in which the first coking stage is once-through fluid coking, and the heavy oil separated from the fluid coking zone effluent is coked in a second coking stage, which is delayed coking.

  • Patent number: 4057487
    Abstract: A hydrocarbonaceous oil is introduced to a quench and scrubbing zone mounted on a fluid coking reactor. Heat from the coker vapor product vaporizes a portion of the hydrocarbonaceous oil. The unvaporized portion of the oil is used to quench and scrub the coker vapor product. The bottoms fraction of the quench and scrubbing zone is passed to a vacuum distillation zone to recover a heavy oil fraction and to produce a vacuum residuum for use as coker feed.

    Abstract: This invention relates to a novel activated fluid coke composition, a method for forming same, and an improved process for removing organic material from waste water by contacting said waste water under adsorption conditions with said activated fluid coke. The activated fluid coke may be prepared by contacting fluid coke with a gaseous mixture containing steam at temperatures of at least about 1500.degree. F. for a period of time sufficient to convert at least 35 weight % of the fluid coke to gaseous products. The activated fluid coke so formed preferably has a total surface area of at least 400 square meters per gram, and a pore volume of at least 0.20 cubic centimeters per gram.

  • Patent number: 4007092
    Abstract: A low sulfur coke product is obtained in an integrated fluid coking and gasification process in which an oxygen-containing gas is introduced into the upper portion of the gasification zone and steam is introduced into the lower portion of the gasification zone. The desired degree of coke desulfurization is controlled by controlling the thickness of the gasifier coke layer on the gaseous reactor leaving solids per pass.
