PROBLEM TO BE SOLVED: To provide a method of decomposing and removing ammonia which is capable of eliminating a possibility of by-producing NOx and is capable of cracking and removing the ammonia at a high yield. SOLUTION: The method of decomposing and removing the ammonia by bringing gas containing the ammonia into contact with an ammonia decomposition catalyst comprises using the catalyst formed by depositing ruthenium as an active metal on a carrier consisting of at least >=1 kinds of the porous materials selected from the group consisting of γ-Al2 O3 , θ-Al2 O3 , ZrO2 , TiO2 , TiO2 .ZrO2 , SiO2 .Al2 O3 , Al2 O3 .TiO2 , SO4 /ZrO2 , So4 /ZrO2 .TiO2 , Y type zeolite, X type zeolite, ferrierite mordenite and zeolite βas the ammonia decomposition catalyst. |
