PURPOSE:To enhance heat transfer capacity near to the tubular wall of a reaction tube by introducing reactive gas into a reactor wherein a reforming catalyst is packed and also the reforming catalyst is held to the surface of the tubular wall, and converting reactive gas into reformed gas. CONSTITUTION:Reactive gas 11 such as a gaseous mixture of i.e. hydrocarbon and steam is fed in a reaction tube 1 via a conduit 3. Since comparatively large endothermic reaction is caused in the reaction tube, the part packed with reforming catalytic particles 9 is heated by a heated catalyst 13 from the outside of the reaction tube 1 to maintain it at 800 deg.C temp. After the reactive gas 11 being the gaseous mixture is introduced into the reaction tube 1 through the conduit 3, reforming reaction is caused in the packed layer of the reforming catalytic particles 9 and on the surface of a reforming catalyst 10 stuck on the surface of the inner wall of the reaction tube 1 and in the inside thereof to reform it to hydrogen-enriched gas. |
