ANODIZED ALUMINUM CATALYST CARRIER HAVING INCREASED BET SPECIFIC SURFACE AREA AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an anodized aluminum catalyst carrier having BET specific surface area larger than the catalyst carrier hereto in use and to provide its manufacturing method.;SOLUTION: The Anodized aluminum catalyst carrier having increased BET specific surface area is distinguished by that pore diameters of fine pores in an anodized aluminum surface formed by anodic oxidation are enlarged by acid treatment of the anodized aluminum surface of a metallic plate having the anodized aluminum surface and then subjects the same to hydration treatment and further sintering are executed.;COPYRIGHT: (C)2002,JPO
