FIELD: energy.
SUBSTANCE: invention can be used in hydrogen power engineering and steel industry. Method includes placing in reaction space carbon-rich granules with particle size of 0.1–100 mm, containing at least 80 wt% of carbon, feeding hydrocarbons and subjecting them to thermal decomposition into carbon and hydrogen. Thermal energy required for decomposition of hydrocarbons is produced outside reaction space, followed by feeding heated gaseous heat carrier – hydrogen or nitrogen. Carbon-rich granules used are coke fines, low-quality coke from coke and by-product process based on brown or hard coal and/or coke obtained from biomass, and passing it through reaction space continuously in form of movable or fluidised bed. Part of carbon-containing granulate removed from reaction space is returned into reaction space.
EFFECT: invention enables to produce simultaneously carbon and hydrogen of high purity on an industrial scale.
