摘要：

Ag(x)/ZSM-5　(x=3,　6,　9)　catalysts　for　selective　catalytic　reduction　of　nitric　oxide　by　methane　(CH4-SCR)　were　prepared　by　impregnation　method.　The　physicochemical　properties　of　the　catalysts　were　characterized　by　XRD,　SEM,　NH3-TPD,　Py-FTIR,　XPS　and　NO-TPD.　The　catalytic　performance　for　selective　catalytic　reduction　of　nitric　oxide　by　methane　was　evaluated　in　a　fixed-bed　micro-reactor　under　atmospheric　pressure　and　the　influence　of　Ag　loading　were　investigated.The　results　show　that　the　impregnation　of　Ag　has　changed　the　acidity　and　amount　of　acid　of　the　catalyst　and　improved　the　adsorption　and　desorption　performance　of　NO　on　ZSM-5　molecular　sieve.　With　the　increase　of　Ag　loading,　Ag　particle　size　increases　and　results　in　higher　methane　activation　as　well　as　the　denitration　activity　of　CH4-SCR　over　Ag(x)/ZSM-5　catalyst.　Ag(9)/ZSM-5　has　better　denitration　activity　and　the　NO　conversion　is　41.87%　at　350　.　©　2020,　Science　Press.　All　right　reserved.
