FIELD: chemistry.
SUBSTANCE: invention relates to field of chemistry. Exothermally generated product 4 of synthesis-gas is produced in the first reactor by conversion of the first part of hydrocarbon raw material flow. Endothermally converted product 7 of synthesis-gas, in which, at least, part of heat is used from exothermally generated synthesis-gas product, is obtained in heat-exchange reforming installation. Flow 7 is cooled. Cooled flow 8 is passed through high-temperature shift reactor, in which part of CO reacts with vapour with production of carbon dioxide and hydrogen. Obtained flow 9 is directed into low-temperature shift reactor. Obtained flow 11 is supplied into separator, which separates methane from combination of exothermally generated synthesis-gas product and endothermally converted synthesis-gas product with obtaining flow of discharge gas. Heater burns, at least, part of discharge gas, using exhaust from gas turbine as oxidiser, producing flows of overheated vapour and hydrocarbon raw material, used in exothermally- and endothermally generated synthesis-gas product. Generator generates energy, using gas turbine to bring oxygen-producing installation into action, providing oxygen for synthesis-gas generation.
EFFECT: invention makes it possible to obtain highly pure hydrogen under high pressure.
