Abstract：

The　influence　of　catalysts　with　different　templates　on　direct　decomposition　of　NO　in　cement　kiln　exhaust　was　studied　in　this　paper.　The　NO　direct　decomposition　rate　of　porous　catalyst　materials　with　different　templates　was　determined　by　infrared　spectrometer.　And　pore　structure　and　the　microstructure　of　the　catalysts　were　characterized　by　BET　surface　area,　nitrogen　adsorption-desorption.　The　results　show　that　the　catalytic　performance　of　porous　catalyst　without　any　template　is　better　than　catalysts　with　other　templates　at　low　temperature.　When　the　temperature　reached　550　°C,　NO　decomposition　rate　of　porous　catalyst　with　CTAB　could　reach　to　more　than　80%.　And　meanwhile,　the　catalysts　with　organic　template　reagent　have　higher　BET　surface　area　than　those　with　inorganic　template　agent.　With　the　increasing　of　the　reaction　time,　the　NO　decomposition　rate　decreases.　After　reaction　for　3　hours,　the　decomposition　rate　decreases　from　80%　to　40%.　©　2018　Trans　Tech　Publications,　Switzerland.
