Abstract
The novel Cu-BTC/FA materials were synthesized with Cu-BTC as the active component and solid fly ash as the catalyst carrier. then developed as the NO removing catalysts for low temperature selective catalytic reduction (SCR) with NH3. The physic-chemical properties of catalyst samples were characterized by multiple techniques, such as SEM, XRD, FTIR, XPS, TPR and Raman. The results show that: (1) The active component Cu-BTC loading ratio is 9%, the denitration performance is excellent and has strong stability. Under this condition, the catalyst showed the highest NH3-SCR activity, giving 94% NO conversion. (2) The catalysts show the good cyclic and stability in SCR denitration under 200 ℃. (3) It still shows high NO removal rate and good stability under the condition of SO2, and the denitration rate is as high as 78.36%. (4) There is a certain degree of resource integration for carrier fly ash, which not only treats air pollutants to a certain extent, but also achieves the purpose of solid waste recycling.
