CYLINDRICAL STEAM REFORMER

摘要

A cylindrical steam reformer which has a reforming catalyst disposed in a gap between an inner and outer cylinder. Metal zigzag plate elements and metal planar plate elements are arranged alternately between the cylinders such that one metal planar plate element is positioned at the outer wall surface of the inner cylinder and another metal planar plate element at the inner wall surface of the outer cylinder. The walls of the cylinder and metal plates are brazed to form a honeycomb base material. A reforming catalyst is supported on the surface of the metal planar plate element on the outer wall surface-side of the inner cylinder, on the surface of each metal zigzag plate element, on the surface of each metal planar plate element and on the surface of the metal planar plate element on the inner wall surface-side of the outer cylinder.
