Abstract

In order to deal with the challenge of the hydrothermal deactivation of selective catalytic reduction of NO_x by NH₃(NH₃-SCR) catalyst and extend its lifetime, a novel Cu/SAPO-5/34 catalyst was prepared, and it almost maintains its deNO_x performance with a high conversion rate of 90% NO_x between 175 °C and 400 °C after undergoing the rigorous treatment at 800 °C for 12 h. Thus, Cu/SAPO-5/34 is more recalcitrant to the high-temperature hydrothermal deactivation than Cu/SAPO-34. Besides, the formation of N₂O is always below 3×10⁻⁶(3 ppm) during the whole reaction temperature, performing an advanced catalytic selectivity. The effect of high-temperature hydrothermal treatment on the morphology, structure and texture property, the acid sites, as well as the active copper species were investigated. These characterizations manifest that the optimized high-temperature hydrothermal stability is associated closely with the good structural stability over Cu/SAPO-5/34-HT, which facilitates to preserve reaction sites, and then showing the better hydrothermal stability than Cu/SAPO-34.
