Functional-membrane coated Mn-La-Ce-Ni-Ox catalysts for selective catalytic reduction NO by NH3 at low-temperature
چکیده انگلیسی
Functional-membrane coated Mn-La-Ce-Ni-Ox catalysts for NH3-SCR at low-temperature were designed and prepared. The catalytic activity for NO removal and the anti-poison ability of catalyst were also investigated and discussed. Result showed that functional-membrane coated Mn-La-Ce-Ni-Ox catalysts had the highest NO removal efficiency of 93% at 180 °C and after injecting 10 vol% H2O and 300 ppm of SO2, the NO removal efficiency still reached about 80%. The functional membrane could not only prevent H2O absorbing on the surface of catalyst and produce sulfur ammonium salt, but also effectively isolate the poison contacting catalyst active sites.
