英文摘要 | In this work, the Cu-SSZ-39 catalyst was sulfated at different temperatures (200 degrees C, 400 degrees C or 600 degrees C) in the presence of water to investigate the effects of sulfation on its catalytic performance in NH3-SCR. Sulfation at 200 degrees C and 400 degrees C resulted in a significant decrease in NOx conversion at low temperatures, while sulfation at 600 degrees C showed only slight effect on the SCR activity of Cu-SSZ-39. The coverage of active sites by H2SO4 was the main reason for the deactivation of the catalyst sulfated at 200 degrees C and 400 degrees C, while the formation of stable CuSO4 species should also be responsible for the catalytic activity loss of the catalysts sulfated at 200 degrees C, 400 degrees C and 600 degrees C. After regeneration at 600 degrees C, the activities of the sulfated catalysts could be recovered partially but were still lower than those of the fresh catalysts, due to the formation of stable sulfated Cu species. |
