摘要：

Catalytic performance of Ir catalysts for reduction of nitric oxide with carbon monoxide in the presence of SO, and excess oxygen was investigated. NO was selectively reduced with CO on Ir/silicalite in an oxidizing atmosphere containing 1% to 10% O-2 in the temperature range of 300-500 degrees C. The catalytic activity was scarcely influenced by 150 ppm SO2.
