FIELD: chemistry.

SUBSTANCE: invention relates to production of hydrogen or synthesis gas during processing of various fuels. Method of producing synthesis gas or hydrogen by partial oxidation of fuel, including: methane, propane, butane, liquid hydrocarbons, hydrogen sulphide, solid fuels, including biomass, solid hydrocarbons, coal, as well as their mixtures in a multi-reactor cyclic reactor includes: heating to high temperature of at least part of reactor chamber filled with solid porous material; feeding into the reactor two reagents - fuel and oxygen-containing gas - in insufficient amount of combustible for complete oxidation; reaction of fuel and oxygen-containing gas; installation of gas flow in reactor by supply of gaseous reagent in one part of reactor and discharge of gaseous reaction products in form of synthesis gas from other part of reactor; temperature measurement in reactor; gas flow switching in reactor, at which synthesis gas extraction in the part of reactor, in which solid porous material has been cooled by supply of gaseous reagent, is started, wherein reagents are fed into reactor separately: one of reagents, gaseous reagent - A - is supplied to one part of reactor, flow of reagent A is fed through layer of heated solid porous material, and second reagent - B - is fed into reactor downstream of gas flow and mixing reagent B and heated with heat exchange with solid porous material reagent A, and the reaction products stream in the form of synthesis gas is directed through a layer of solid porous material, wherein the process is carried out in a cyclic multi-reactor reactor, made in form of at least two cyclically connected retort volumes 1–4, mainly filled with solid porous material, equipped with locking devices 9₁, 9₂, 9₃, 9₄, covering and opening gas flow between retorts, where each retort 1–4 is equipped with devices for input of reagents and synthesis gas outlet; extraction of synthesis gas is carried out from a retort, gas flow from which is closed in the following by cycle retort, and during heating of solid porous material in retort, from which synthesis gas is extracted, flow switching is performed: opening the stream from the retort, from which the synthesis gas was extracted, into the next retort, shutting off the gas flow from the next retort into the next retort after it, synthesis gas is withdrawn from the next retort and reagents A and B are switched to one retort by cycle.

EFFECT: process ensures high energy efficiency with minimum raw material consumption at continuous conversion of combustible raw material into synthesis gas and/or hydrogen.
