Simultaneous SO{sub 2}/NO{sub x} abatement using zeolite-supported copper. Progress report, October 1, 1992--December 31, 1992
The proposed research seeks to advance/improve current flue gas cleanup catalyst technology by modifying promising copper-exchanged zeolite NO decomposition catalysts which reduce NO to elemental nitrogen and oxygen in the absence of an added reducing gas. The authors believe that this approach has great potential. Copper on alumina has been investigated by the Pittsburgh Energy Technology Center (PETC) as a NO{sub x}/SO{sub 2} abatement catalyst. Copper on alumina acts as a sorbent for SO{sub 2}, forming a surface sulfate upon adsorption in an oxygen-containing atmosphere, and as a catalyst for selective catalytic reduction (SCR) of NO{sub x} using ammonia; both CuO and CuSO{sub 4} on the surfaces of these materials are active SCR catalysts. SO{sub 2} adsorption in the PETC studies was carried out at 673K, a temperature well within the range for active NO decomposition by the Cu-ZSM-5 catalyst. The authors believe that by beginning with a material which decomposes NO without needing an added reducing gas, they will be able to design a catalyst which will act as a regenerable NO{sub x}/SO{sub 2} abatement catalyst which does not need ammonia to accomplish NO{sub x} reduction, and which will accomplish SO{sub 2} abatement by adsorption, similar to the copper on alumina catalyst. Coupled with a SO{sub 2} oxidation catalyst, this successful system will be able to remove both NO{sub x} and SO{sub 2} from flue gases with no added reducing agent and no waste.
