摘要：

Compared to the Ag/Al2O3 catalyst, a two-stage catalyst composed of an Ag/Al2O3 layer followed by a Sn/Al2O3 layer shows higher low-temperature activity and a wider temperature window. Its activity below 350degreesC is enhanced in the presence Of SO2. Even in the presence of H2O and SO2, the performance of the same catalytic system is still satisfactory.
