Hydrogen as highly efficient and clean secondary energy is becoming one of primary energy sources in the future. Methane-reforming is a highly efficient, economical and widely used process for hydrogen production. Catalysts are the important ingredients of reforming processes, and the type, activity and stability of methane-reforming catalyst exhibit a great influence on the conversion efficiency, purity and cost of hydrogen from methane-reforming. This paper reviews the types and preparation methods of catalysts for steam reforming of methane, partial oxidation and carbon dioxide reforming of methane, and analyzes catalytic mechanism of methane-reforming for the production of hydrogen.
