METHOD FOR MANUFACTURING PARTICULATE CATALYST, PARTICULATE CATALYST AND REFORMER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a particulate catalyst, by which the particulate catalyst having high activity and a long service life can be manufactured at a low cost and to provide a reformer to be operated at low temperature.

SOLUTION: The particulate catalyst having ≤10 μm average particle size is manufactured by forming a liquid droplet having ≤30 μm diameter from a catalytically-active component-containing aqueous solution and introducing the formed liquid droplet into a plasma flame under atmospheric pressure by using an argon carrier gas having ≤5% oxygen content. Since water-soluble salts are used as raw materials of a catalytically-active component and mixed homogeneously with one another at molecular levels to prepare the catalytically-active component and the prepared catalytically-active component is pyrolyzed instantaneously in the plasma flame, the particulate catalyst having uniform and fixed particle size can be obtained.
