FIELD: hydrogen production processes. ^ SUBSTANCE: invention relates to catalytic processes of hydrogen production from hydrocarbon-containing gases. Method of invention comprises elevated-pressure catalytic decomposition of methane and/or natural gas into hydrogen and carbon followed by gasification of the latter with the aid of gasification reagent in several in parallel installed interconnected reactors, each of them accommodating preliminarily reduced catalyst bed. When one of reactors is run in methane and/or natural gas decomposition mode, the other gasifies carbon, the both operation modes being regularly switched. Operation period in one of the modes ranges from 0.5 to 10 h. Carbon gasification reagent is, in particular, carbon dioxide and catalyst utilized is reduced ferromagnetic thermally stabilized product consisting of iron oxides (30-80 wt %) and aluminum, silicon, magnesium, and titanium oxides. Methane and/or natural gas is decomposed at 625-1000°C and overpressure 1 to 40 atm. ^ EFFECT: ensured environmental safety and increased productivity of process. ^ 3 cl, 1 dwg, 8 ex |
