Hydrogen producer

Abstract

Abstract PURPOSE:To prevent the deformation of a hydrogen producer having a double- tubed structure and to easily exchange a reforming catalyst by connecting the outer and inner tubes of each reaction tube to separate tube sheets and discharging a prduced gas from the space between both sheets. CONSTITUTION:The top of the inner tube 4 of each reaction tube is connected to a tube sheet 13, and fins 14 are attached to the periphery of the tube 4 between the sheet 13 and a tube sheet 3 connected to the outer tube 2 of the reaction tube. A gaseous starting material is introduced into a space A from an inlet 16, passes through the inner tubes 4, and causes a reforming reaction in the presence of a reforming catalyst 6, and it is discharged from an outlet nozzle 15 as a produced reformed gas. The temp. of this reformed gas is made low by the sheet 13, the tubes 4 and the fins 14 maintained at a low temp. by the gas passing through the tubes 4 at a low temp. As a result, the temp. of the reformed gas staying in the space B between the sheets 13, 3 is dropped, and the temp. difference between the sheet 3 and the fins 14 is reduced to prevent the deformation of the apparatus. The gaseous starting material is efficiently preheated by the sheet 13 and the fins 14, and the reforming reaction proceeds efficiently.
