Laboratory study of poisoning of a MnO/Fe2O3 catalyst by dimethyl sulfide and dimethyl disulfide.
The catalytic incineration of dimethyl sulfide and dimethyl disulfide in a MnO/Fe(2)O(3) 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/Fe(2)O(3) catalyst, especially at lower temperatures.
