Preparation and characterization of porous ceramic-supported V2O5/TiO2 catalyst for SCR of NOx with NH3 |
| 초록 |
The porous ceramic-supports with constant pore size and with porosity about 80% were prepared by foaming method combined with gelcasting and pseudo double-emulsion method. Titania coating on porous ceramic spheres was developed using a novel processing by sol-gel process. V2O5/TiO2 catalyst was prepared vanadium coating again on titania coated on porous ceramic-supported by impregnation method. The physical properties were characterized by SEM-EDS, XRD and BET. The porous ceramic-supported V2O5/TiO2 catalyst was applied in the selective catalytic reduction (SCR) of NOx by NH3. The NO removal efficiency of this catalyst 96% at a space velocity of 12600/h, NH3/NO mole ratio of 1.0 and reaction temperature of 250-400℃. This work has demonstrated feasibility of V2O5/TiO2 catalyst on porous ceramic-support as catalyst support of SCR of NOx with NH3. |
