FIELD: metallurgy.
SUBSTANCE: invention relates to pyrolysis method of hydrocarbon raw material - natural gas till hydrogen and carbon, including preheating of hydrocarbon raw material and its feeding to pyrolysis stage, implemented while raw material contact with heated heat-transfer fluid, where for heating of heat-transfer fluid it is used gas fuel combustion in oxidiser with oxygen part 0.4-0.95 and coefficient of oxidant discharge 0.4-0.8, and emission gas of combustion is subject to process of energy-chemical accumulation, for which it is fed natural gas, receiving of by-product fuel, at that increasing combustible components parts and reducing gas temperature till 900-1000°C received by-product fuel is cooled till the temperature 25-150°C ensured by heating of material by it hydrocarbon raw, gaseous fuel and oxidant.
EFFECT: expenditures reduction and improvement of the method.
