Composite catalysts consisting of a modified Y zeolite (H-Y, Cu-Y, DAY, or Cu-DAY)and V2O3 and/or TiOj were synthesized by mixing a modified Y zeolite with n-hexane solutions of ammonium monovanadat and/or isopropyl orthotitanate. Both reflux and impregnation methods wer: used to add Ti02 to the catalysts. It is found that N2/NOin over the composite catalysts synthesized by ::eflux method is higher than that by impregnation. In addition, N2/NOin increases with oxygen concentration for oxygen concentration less than 2%, while it is independent of oxygen concentration for oxygen concentration greater than 2%. Effect of Ti02 in The catalyst on N2/NOin varies depending on the type of :atalysl and the method of synthesis. N2/NOin increases with the addition of copper and/or vanadia to composite catalysts. Furthermore, these composite catalysts are S02 resistant. |
