Abstract
Effects of the method of burning and addition of catalysts in the chimney of civil-used stove on emission of air pollutants were studied. Alumina-supported copper and manganese oxides and palladium catalysts were used to purify the flue gas emitted from the civil-used stoves. The results show that, in upper burning case, both Cu–Mn–O/Al 2O 3 and Pd/CuO/Al 2O 3 catalysts can decrease the ratio of CO/CO 2 to <0.01, and remove SO 2 and volatile organic chemicals (VOC) from the flue gas to some extent. Deactivation of the catalyst results from the accumulation of sulfate groups on catalyst support. The life of the catalyst can be extended by adding a honeycomb of lime before the catalyst.
