  • Process for hydroconverting of a heavy hydrocarbonaceous feedstock
    Patent number: 7585406
    Abstract: A Process for hydroconverting of a heavy hydrocarbonaceous feedstock comprising a catalyst to produce lower boiling hydrocarbon products. The method can be used for the high- boiling point residues of oil refining (asphaltene, the residues of vacuum and under pressure distillation of oil, and the useless and heavy materials of thermo catalytic processes), heavy oil, natural bitumen, and bitumen-containing sands. It can also be used in oil refinery industries for the production of gas, gasoline fractions, distillation gas oil, concentrate of ash containing metals and chemical fertilizers.

The method can be used for the high-boiling point residues of oil refining (asphaltene, the residues of vacuum and under pressure distillation of oil, and the useless and heavy materials of thermo catalytic processes), heavy oil, natural bitumen, and bitumen-containing sands. It can also be used in oil refinery industries for the production of gas, gasoline fractions, distillation gas oil, concentrate of ash containing metals and chemical fertilizers. The process overcomes disadvantages like low conversions, coke production during the reaction, touchiness to the feed (to the metals and solids present in the feed which deactivate the catalyst), high investment and operational costs and the need for pre-purification units, for the elimination of heavy substances.
