Ammonia Decomposition Catalyst and Process for Decomposition of Ammonia Using the Catalyst

摘要

Disclosed is a catalyst useful for catalytic decomposition of high concentration ammonia, and also disclosed is a process for decomposing ammonia using the catalyst. As the ammonia decomposion catalyst, a catalyst which supports a metallic element selected from Fe, Co, Ni and Cu by ion exchange method on porous silica alumina having an Si/Al atomic ratio of 1 to 90 and a specific surface area of 200 to 900 m2/g and contains a noble metal selected from Ru, Rh, Pd, Ir and Pt in an amount of 10 to 500 ppm based on the total mass of the catalyst is useful.
