Effects of catalyst loading amount, reaction temperature, O-2 concentration, NH3/NO molar ratio and SO2 on low-temperature catalytic performance of the Mn-La-Ce-Ni-O-x (Mn/La/Ce/Ni = 2.5:2.5:1:1 in mol)/PPS for NH3-SCR of NO were mainly studied. Results showed that the filter with catalyst loading amount of 250 g/m(2) obtained more than 95% NO removal efficiency at 200 degrees C under filtration velocity of 1 m/min. The NO removal efficiency was still above 85% by injecting 300 ppm SO2 at 200 degrees C. Anyway, the Mn-La-Ce-Ni-O-x/PPS catalytic filter is promising to achieve the expectation of simultaneous removing particulate and NOx from low-sulfur flue gas in cement kiln.
