DeNOx COPPER/ZEOLITE CATALYST WITH HYDROTHERMAL STABILITY AND METHOD FOR PREPARING THEREOF |
| 摘要 |
PURPOSE: A DeNOx Cu/zeolite catalyst having good hydrothermal stability and NOx removal efficiency is provided. CONSTITUTION: The method comprises steps of (a) mixing zeolite having a Si/Al mole ratio of 14 to 95 with an aqueous solution of a Cu salt; (b) ion-exchanging the mixture at the temperature of 4 deg.C to room temperature; and (c) drying and sintering the ion-exchanged mixture. The DeNOx Cu/zeolite catalyst is characterized in that 0.1-10 wt.% of Cu regarding total weight of the catalyst is supported on the zeolite having the Si/Al mole ratio of 14 to 95.
