Abstract

Effects of catalyst loading amount, reaction temperature, O₂ 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 250g/m² obtained more than 95% NO removal efficiency at 200°C under filtration velocity of 1m/min. The NO removal efficiency was still above 85% by injecting 300ppm SO₂ at 200°C. Anyway, the Mn-La-Ce-Ni-O_x/PPS catalytic filter is promising to achieve the expectation of simultaneous removing particulate and NO_x from low-sulfur flue gas in cement kiln.
