Sn/γ-Al 2O 3 were effective and highly stable catalysts for NO reduction with propene under high partial pressures of oxygen and water. The activity depended on the Sn loading. For a 10 wt% Sn/Al 2O 3 at 475-500°C, 58% conversion of 1000 ppm NO to N 2 was obtained in the presence of 10% water and 15% O 2, at a space velocity of 30,000 h -1, and 77% conversion at 15,000 h -1. The NO conversion increased with O 2 partial pressure but was suppressed by water below 500°C. The activity was also suppressed by SO 2 but could be restored slowly after the removal of SO 2.
