METHOD OF HEAVY CHARGE HYDROCONVERSION IN DISPERSE CATALYST Russian patent published in 2010 - IPC C10G49/04 C10G65/02 

FIELD: oil and gas production.

SUBSTANCE: invention relates to the method of hydroconversion combined with desulfurization in a reaction zone of sulphur-containing heavy hydrocarbon charge with hydrogen and a solid catalytic phase added, while said solid catalytic phase is prepared of a catalytic precursor wherein the conversion products supplied from the reaction zone are separated in an internal or external gas-liquid separator, and the catalytic precursor is injected in a liquid portion of conversion products recycled in the reaction zone; the portion saturated with dissolved hydrogen sulphide and containing pyrobitumens and/or resins and the catalytic precursor is injected in the specified liquid products with temperature within TS+/-10°C where Ts is outlet temperature of the specified liquid products from the reaction zone, and total pressure is within Ps+/-10 bar where Ps is outlet pressure of the specified liquid products from the reaction zone; said temperature makes 380°C to 500°C, and the prepared mixture reacts in the reaction zone. The invention also concerns an apparatus for implementation of this method.

EFFECT: high-percentage conversion of heavy oil stock.
