The new technology for selective catalytic oxidation of ammonia to nitrogen

摘要

The selective catalytic oxidation (SCO) of ammonia to nitrogen was studied over a series of nobel metal (Pt,Pd,Ir and Rh) -V_2O_5-WO_3 catalysts supported on titania-silica (TS) prepared by comprecipitation method.The addition of Pd and Ir to V_2O_5-WO_3/TS catalyst caused remarkable enhancemdent of the catalytic activity without decreasing the selectivity to N_2.The present catalysts provide remarkably high catalytic performance for SCO of ammonia to N_2 under the practical reaction conditions for an industrial application.
