Effect of Cu-BTC loaded on solid waste fly ash in low-temperature NH3-SCR
Source abstract
Abstract
In recent years, with the continuous development of metal organic frameworks (MOFs), more and more MOFs have been reported. For the prepared materials with a porous structure and a rich specific surface area, they are gradually emerging in the application of environmental pollution control, but the high cost of raw materials limits their development in actual production. In this paper, the prepared Cu-BTC was used as the active component, and the Cu-BTC/FA catalyst was prepared by loading it on a shaped fly ash (FA) carrier. The catalyst performance was evaluated through SCR denitration, sulfur resistance and stability test. And combined with the XRD, FTIR, SEM, XPS, H2-TPR and Raman characterization of the catalyst, the possible denitration mechanism was explained. The results show that when the Cu-BTC loading is 9%, the denitration rate of the catalyst reaches 94%. And it has good stability and sulfur resistance at 200 °C. The possible reason is that NO and NH3 gas molecules are first adsorbed by Cu2+/Cu+ ions, and then Cu2+ is reduced to Cu+ by NH3, and Cu+ is reduced to Cu0 by NH3. Subsequently, Cu+ and Cu0 react with NO and re-convert to Cu2+ and causing the SCR reaction continues.
