<p>PROBLEM TO BE SOLVED: To provide countermeasures of the technical problems about the problem of the sticking of carbon after decomposition, the problem of the sticking of soot during the regeneration of a catalyst, the concern of the soundness of a material with the exothermic reaction of the regeneration and the problem to decrease the regeneration time. SOLUTION: A method of producing a gaseous mixture product containing hydrogen by a thermal catalytic decomposition through the catalyst capable of forming carbon nanotube by the contact with a hydrocarbon from an initial mixture containing at least one kind of the hydrocarbon is provided, the transition of at least 2 catalytic reaction zones are used, the zones are separated from each other respectively in at least 2 different successive reactors R1-R4 or in succession in the same reactor, the successive catalytic zones have at least one of the increased temp. gradient and the increased metal concentration gradient in the catalyst.</p> |
