PURPOSE:In a steam reformer for hydrocarbon gases, the support of the steam- reforming catalyst is made of an integrated structure of multilayered thin walls such as honeycomb or lattice form of heat-resistant basic inorganic substance such as dolomite or chrome magnesite, thus increasing reaction activity. CONSTITUTION:The tubes 7 in the reactor 1 of hydrocarbon gas steam reformer are packed with a reforming catalyst 8. The catalyst is supported on a carrier of a solid base of heat-resistant inorganic substance such as dolomite, magnesia, potassium aluminate or chrome magnesite, which is a polygonal or round cylinder with multilayered thin walls such as honeycomb or lattice structure. The use of such basic substance as a catalyst support extremely lessens the accumulation of carbon during the reaction to increase the reaction activity and permit the great prolongation of catalyst life. |
