FIELD: chemistry.

SUBSTANCE: invention relates to production of synthesis-gas and device for obtaining it. Synthesis-gas is obtained by successive carrying out one or several endothermal and/or adiobatic reformings with water vapour and autothermal reforming with water vapour. Method includes stages of endothermal and/or adiabatic catalytic reforming with water vapour successively, where reformng with water vapour is carried out in one or two endothermal stages successively and/or in one or more adiabatic stages of reforming with water vapour successively with intermediate heating of gaseous raw material, removed from stages of adiabatic reforming, and where containing carbon monoxide gas, characterised by molar ratio of hydrogen to carbon less than 4.5, is added before at least one of endothermal or adiabatic stages of reforming with water vapour and/or before stage of autothermal reforming with water vapour. Device for obtainng synthesis-gas represents reforming system and includes optionally device of preliminary reforming for adiabatic preliminary raw material reforming; one or more devices of endothermal catalytic reforming with water vapour and/or at least first and last adiabatic installations of catalytic reforming with water vapour, connected successively; means for intermediate raw material heating between at least first and last adiabatic reforming-installations with water vapour; autothermal reforming-installation with water vapour with descending flow, connected successively with one or more installations for endothermal reforming with water vapour or with last adiabatic reforming-installation with water vapour; and means for adding carbon monoxide-containing gas, located higher along the flow of one or more endothermal reforming-installations with water vapour or higher along the flow of, at least, first and/or last adiabatic reforming-installations and/or higher along the flow of autothermal reforming-installation.

EFFECT: increase of synthesis-gas production.
