N2 - Catalytic incineration is one of the cost-effective technologies to solve the problem of Volatile Organic Compounds (VOCs). However, some sulfur-containing VOCs, such as methyl mercaptan and dimethyl sulfide, may deactivate the Pt catalyst that is commonly used in the catalytic incineration process. The catalytic incineration of these compounds over a Pt/Al2O3 catalyst was carried out in a bench scale catalytic incinerator. Three kinetic models were used to analyze the results: the power-rate law, the Mars and Van Krevelen model and the Langmuir-Hinshelwood model. A differential reactor design was used for best fit of kinetic models in this study. The results showed that the Langmuir-Hinshelwood model is suitable for the catalytic incineration of both CH3SH and (CH)2S. This suggests that the adsorption of VOC or O2 molecule is important in the process of catalytic incineration of CH3SH and (CH3)2S.
