Supported catalyst for removing nitrogen oxides, method of preparing the same, and removing method of nitrogen oxides using the same |
摘要 |
<p>A supported catalyst for reduction reaction of nitrogen oxides includes a support and an silver (Ag)-based compound and aluminum fluoride which are immobilized in the support. A method for preparing the supported catalyst for reduction reaction of nitrogen oxides includes an impregnation step wherein aluminum fluoride, a hydrate or a salt thereof, and a silver (Ag)-based compound or a hydrate thereof are reacted with a support and a step of calcining the support. Nitrogen oxides in exhaust gas are removed by reacting with a reducing agent, in the presence of the supported catalyst for reduction reaction of nitrogen oxides. Wherein, the supported catalyst has an excellent nitrogen oxide removal efficiency at a practical exhaustion temperature of 270 to 400°C.</p> |
