APPARATUS FOR PROCESSING HYDROCARBON BIOMASS TO OBTAIN HYDROGEN-CONTAINING GASES WITH HIGH ENERGY POTENTIAL Russian patent published in 2020 - IPC C10J3/54 C10J3/56 

FIELD: gas industry.

SUBSTANCE: invention relates to production of hydrogen-containing gases with high energy potential from solid hydrocarbon biomass and can be used in power engineering. Plant for producing hydrogen-containing gases from hydrocarbon biomass comprises a fluidized bed reactor 1 for converting carbon with a hydrogen supply pipeline 6 to consumers, fluidized bed reactor 2 for decomposition of calcium carbonate CaCO₃ with carbon dioxide supply pipeline 7 to consumers, cyclone 12 with hot air supply pipeline 8 with oxygen shortage to consumers and reactor 3 for oxidation of iron oxide FeO. Fluid bed reactor 1 for carbon conversion has superheated steam supply pipe 4, CaO calcium loading supplement channel 25, channel 11 for removal of waste calcium oxide CaO and ash. Reactor of boiling layer 2 is connected by top 37 and bottom 38 overflows with reactor of boiling layer 1 and has channel 9 of additional loading of calcium carbonate CaCO₃ and hematite Fe₂O₃ and channel 10 for removal of spent calcium carbonate CaCO₃ and hematite Fe₂O₃. Reactor 3 for oxidation of iron oxide FeO has compressed hot air supply pipeline 5 and is connected by bottom linear overflow 39 with fluidized bed reactor 2 for decomposition of calcium carbonate CaCO₃, and upper linear overflow 40 with cyclone 12, which is connected to reactor of boiling layer 2. Pyrolysis furnace 14 is additionally installed in the plant, which contains furnace 16 with combustion products combustion products outlet channel 18, inclined prechamber 36, retort 13 for pyrolysis of hydrocarbon biomass with pyrolysis gas discharge channel to consumers 19. Retort for pyrolysis of hydrocarbon biomass has superheater 26 with pipeline of wet steam supply to overheating and internal burner for pyrolysis gas combustion in furnace, wherein superheater is connected to superheated steam supply pipe to fluidized bed reactor for carbon conversion and boiling bed reactor for decomposition of calcium carbonate CaCO₃, as well as external burner 21 with blowing fan 22 and air heater of compressed air 28, connected to compressed air pump 23, which is connected to atmospheric air suction channel 24, note here that compressed air heater is communicated via compressed air feed pipeline with FeO oxidation furnace.

EFFECT: reduced costs when producing hydrogen-containing gases.
