摘要：

A two-stage packing of a 30 wt.% Ga2O3/Al2O3 catalyst and a mixture catalyst of 30 wt.% Ga2O3/Al2O3 With 10 Wt.% of Mn2O3 is shown to be quite efficient to NO selective reduction by a lower hydrocarbon under lean conditions. A high NO reduction conversion was observed in the temperature range of 200-600 degrees C.
