FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing hydrogen from biomass and can be used for producing hydrogen-containing products by producing hydrogen from pyrolysis products of vegetal biofuel in systems of energy accumulation and transport, as well as in systems for production of fuel for vehicles and stationary power plants. Method involves biomass grinding and drying, its further pyrolysis using heated solid heat carrier and superheated steam, separation of hydrogen-containing gases of pyrolysis and pyrolysis mass, which is subjected to high-temperature gasification. Solid heat carrier used is carbonates, forming oxides at high-temperature gasification, solid heat carrier heating is performed by combustion of pyrolysis mass of oxygen produced during electrolysis of water formed during biomass drying process.
EFFECT: technical result consists in reduction of heat consumption, as well as allowing to produce various energy carriers of various biomass in the absence of oxygen consumption from the atmosphere.
