AMMONIA OXIDATION DEGRADATION-HYDROGEN GENERATION CATALYST, AND HYDROGEN MANUFACTURING DEVICE

摘要

To provide an ammonia oxidation degradation catalyst having excellent property in cold start property of oxidation degradation of ammonia, and a hydrogen manufacturing method and a hydrogen manufacturing device using the catalyst.SOLUTION: The hydrogen manufacturing method initiates an oxidation degradation reaction of ammonia by using heat generation due to adsorption of ammonia to a zeolite carrier when hydrogen is manufactured by oxidation degrading ammonia by contacting a raw material gas L1 containing ammonia and oxygen with an ammonia oxidation degradation catalyst 20 having one or more kind of catalyst metal selected from a group consisting of Ru, Co, Rh, Ir and Ni and the zeolite carrier carrying the catalyst metal.SELECTED DRAWING: Figure 1
