METHOD AND EQUIPMENT FOR MULTI-STAGE LIQUEFYING OF CARBON-CONTAINING SOLID FUEL Russian patent published in 2012 - IPC C10G1/00 C10G1/06 C10J3/00 

FIELD: oil and gas industry.

SUBSTANCE: method includes the following stages: 1) one or several types of carbon-containing solid fuel are mixed with residual oil till formation of fuel-residual oil suspension, after that this fuel-residual oil suspension is dewatered via heating and then partially liquefied by way of hydrogenation at low-average pressure, as a result there obtained are light oil components and residual slurry; 2) light oil components obtained at stage 1) are hydro-refined for obtaining refined oil; 3) residual slurry obtained at stage 1) are gasified for obtaining synthetic gas; 4) synthetic gas obtained at stage 3) is transferred into oil of synthesis F-T with the help of simple process of synthesis F-T; 5) oil of synthesis F-T obtained at stage 4) is then hydro-refined and undergoes hydro cracking for obtaining refined oil that is further fractionated for obtaining high-quality oil products, including liquefied petroleum gas (LPG), gasoline, aviation kerosene, diesel oil and other related chemical products. Invention also refers to reactor with three-phase pseudoliquid layer.

EFFECT: effective conversion of carbon-containing solid fuel to oil products.
