    摘要: A hydrocracking process for treating a first and a second heavy hydrocarbon feedstream, in which the first heavy hydrocarbon feedstream contains undesired nitrogen-containing compounds, sulfur-containing compounds and poly-nuclear aromatic compounds. The process includes contacting the first heavy hydrocarbon feedstream with adsorbent material to produce a hydrocarbon stream having a reduced content of nitrogen-containing, sulfur-containing compounds and poly-nuclear aromatic compounds. The second heavy hydrocarbon feedstream is combined with the adsorbent-treated heavy hydrocarbon stream. The combined stream is charged to a hydrocracking reaction unit. The hydrocracked effluent is fractioned to recover hydrocracked products and a bottoms stream containing heavy poly-nuclear aromatic compounds, and bottoms are contacted with adsorbent material to produce an adsorbent-treated fractionator bottoms stream having a reduced content of heavy poly-nuclear aromatic compounds, and are recycled to the hydrocracking reaction unit.

    摘要: A system and process for desulfurizing a hydrocarbon feed stream containing organosulfur compounds is provided. In general, the system includes a conventional hydrotreating unit through the high pressure cold or hot separator. Aqueous oxidant and an oxidative catalyst are mixed with the hydrotreated hydrocarbon effluent from the high pressure cold or hot separator, and oxidative desulfurization reactions occur in the low pressure separation zone, thereby minimizing or eliminating the requirement of additional oxidative desulfurization reactors.

    摘要: An integrated process and system for conversion of a heavy crude oil to produce transportation fuels is provided. The process includes separating the hydrocarbon feed into an aromatic-lean fraction and an aromatic-rich fraction. The aromatic-rich fraction is hydrocracked under relatively high pressure to convert at least a portion of refractory aromatic organosulfur and organonitrogen compounds and to produce a hydrocracked product stream. Unconverted bottoms effluent is recycled to the aromatic separation step. The aromatic-lean fraction is cracked in a fluidized catalytic cracking reaction zone to produce a cracked product stream, a light cycle oil stream and a heavy cycle oil stream. In certain embodiments the aromatic-lean fraction can be hydrotreated prior to fluidized catalytic cracking.
