摘要：

The catalytic incineration of dimethyl sulfide and dimethyl disulfide in a MnO/Fe2O3 fixed bed catalytic reactor was studied. This paper provides information on the affect of the operating parameters that included: inlet temperature, space velocity, VOC concentration and O-2 concentration. The results show that the conversion of VOCs increases as the inlet temperature increases and the space velocity decreases. The higher the concentration of VOCs, the lower their conversions. The O-2 concentration has no affect on the conversion of VOCs. VOCs have poisoning affects on the MnO/Fe2O3 catalyst, especially at lower temperatures. (C) 2003 Elsevier Science B.V.
