    摘要： A process for removing metal from a metal-containing hydrocarbon oil such as a heavy crude is disclosed which comprises:(a) contacting a hydrocarbon oil phase containing at least one metal selected from the group consisting of vanadium and nickel with an aqueous phase of dissolved phosphorous compound capable of forming a compound or a complex with said metal, said aqueous phase containing a substantial quantity of water relative to the amount of liquid hydrocarbon contacted therewith, said contacting resulting in the removal of a substantial quantity of the metal from the hydrocarbon oil phase to the aqueous phase; and,(b) separating the metal-containing aqueous phase from the demetalated hydrocarbon oil phase prior to subjecting the latter to downstream catalytic processing.

    摘要： A catalytic composite and its use in the fluidized catalytic cracking of hydrocarbons in the absence of added hydrogen. The composite comprises a binder material, a crystalline aluminosilicate, preferably a Y-type zeolite, and diatomaceous earth. Optional ingredients are kaolin, barium titanate and discrete particles of porous alumina. Absent from the composite is a supported catalytically active metal or metal oxide. The catalytic composite of the invention achieves higher gasoline production with lower coke production as compared to FCC catalysts with no diatomaceous earth content.
