Chlorinated volatile organic compounds (CVOCs) are regarded as hazardous atmospheric contaminants. Catalytic total oxidation has been considered as solution for CVOCs removal because of its low operating temperature and high selectivity toward non-toxic compounds (H2O, CO2 etc.). However, carbon dioxide can cause another environmental problem of global warming (greenhouse effect) and it is difficult to be utilization because of its stability. On the other hand, carbon monoxide is usable in synthetic process of various chemical compounds. Thus, catalytic partial oxidation with minimized CO2 emission can be a promising method for CVOCs removal. In this study, 1,2-dichloroethane (DCE) catalytic partial oxidation reaction was investigated over VOx catalyst supported on Al-Ti mixed oxide. The VOx/(Al2O3-TiO2) catalyst showed excellent activity and selectivity toward CO because of the synergistic effect associated with acidic property of support material and reducibility of active material. |
