Title:
PREPARATION OF REACTION TUBE FOR CATALYTIC METHANOL REFORMING
Document Type and Number:
Japanese Patent JPH02280838
Kind Code:
A
Abstract:
PURPOSE: To obtain a catalyst by dipping a metallic reaction tube material containing nickel and copper in a molten aluminum to form an aluminum layer on the metallic material, activating the surface of the metallic with an alkali.
CONSTITUTION: A metallic reaction tube material containing nickel and copper as a reaction tube to reform methanol or a mixture of methanol and water into a hydrogen-containing gas is dipped in molten aluminum to form a metal aluminum layer on the surface of the tube material. After that, aluminum is leached for the metal aluminum layer by an alkali such as sodium hydroxide in order to activate the surface. A reaction tube having a high catalytic function is thus obtained.
