Abstract:
A process for the hydroprocessing of a gas oil (GO) hydrocarbon feed to provide high yield of a diesel fraction. The process comprises a liquid-full hydrotreating reaction zone followed by a liquid-full hydrocracking reaction zone. A refining zone may be integrated with the hydrocracking reaction zone. Ammonia and other gases formed during the hydrotreatment are removed in a separation step prior to hydrocracking.

Abstract:
A process for catalytically cracking a hydrocarbon oil containing sulfur and/or nitrogen hydrocarbon constituents by dissolving excess hydrogen in the liquid hydrocarbon feedstock in a mixing zone at a temperature of 420°C to 500°C and a hydrogen-to-feedstock oil volumetric ratio of 300: 1 to 3000:1, flashing the mixture to remove remaining hydrogen and any light components in the feed, introducing the hydrogen saturated hydrocarbon feed into an FCC reactor for contact with a catalyst suspension in a riser or downflow reactor to produce lower boiling hydrocarbon components which can be more efficiently and economically separated into lower molecular weight hydrocarbon products, hydrogen sulfide and ammonia gas and unreacted hydrogen in a separation zone. Hydrogen present in the liquid phase enhances the desulfurization and denitrification reactions which occur during the conversion process and allows for the removal of significantly more sulfur- and/or nitrogen- containing contaminants from the feedstock in an economical fashion.
Abstract:
One exemplary embodiment can be a hydroprocessing method. The hydroprocessing method can include providing a feed and a stream including hydrogen to a vessel. The vessel may have a catalyst collector and an internal riser. Generally, a catalyst circulates within the vessel by at least partially rising within the internal riser.
Abstract:
A coal tar process is described. A coal tar stream is provided, and the coal tar stream is separated to provide a plurality of hydrocarbon streams. At least one of the hydrocarbon streams is hydroprocessed in a fluidized bed hydroprocessing zone with a catalyst to provide a gaseous volatile product and a solid heavy hydrocarbon product absorbed onto the catalyst. The gaseous volatile product is separated from the catalyst. The catalyst is regenerating by separating the absorbed heavy hydrocarbon product from the catalyst. The regenerated catalyst is recycled into the hydroprocessing zone.
