    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: 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.
