Endothermic reaction apparatus

Abstract

Abstract PURPOSE:To enhance thermal efficiency, by a method wherein a reaction apparatus is provided with parallel reaction tubes in a reaction vessel and combustion gas passages with circular cross sections are provided to the central parts of respective reaction tubes. CONSTITUTION:Plural reaction tubes 21 are parallelly arranged within the reaction vessel 2 of a reaction apparatus. Each reaction tube 21 has a multilayered ring like cross section and the first combustion gas passage 11 is formed to the innermost side, the first partitioned chamber 20a of a reaction chamber to the outside thereof, further a regeneration chamber 30 to the outside thereof and the second partitioned chamber 20b of the reaction chamber to the outermost side. To the outside of the reaction tube 21, the second combustion passage 12 is formed. The interior of the reaction chamber 20 is filled with a steam reforming catalyst 45 and this catalyst is supported on a catalyst support member 22 provided to the inlet 7 of the reaction chamber 20. In addition, to the outlet 8 of the reaction chamber 20, an outflow preventing plate 23 is provided and the upper part of the reaction chamber 20 is hermetically sealed by a cap 24.
