Destruction of trichloromethane with catalytic oxidation

The destruction of dichloroethane over a γ-alumina supported manganese oxide catalyst

“…The catalyst did not seem to deactivate during the differential reaction experiments. This is inconsistent with the results of Lou and Lee [34], which showed that the effect of the O 2 content (%) on the reaction rate was insignificant in the process of catalytic incineration of CHCl 3 . A detailed review of the work in the literature on the effect of O 2 concentration for the catalytic decomposition has been presented by Chu et al [35], Tseng and Chu [36], and Tseng et al [22].…”

Catalytic abatement of trichloroethylene over Mo and/or W-based bronzes

“…At high temperatures (350ºC), this by-product is destroyed and the yield of Cl 2 increases. Bickle et al [58], Lou and Lee [23] and González-Velasco et al [55] also obtained similar results in their oxidation reactions.…”

“…chromium oxide) or mixed (e.g. perovskites) and supported noble metals [21][22][23][24][25][26]. For both types of catalysts, deactivation is one of the main problems [7].…”

Noble metal loaded zeolites for the catalytic oxidation of chlorinated hydrocarbons

“…As for carbon oxides formation, it is worth pointing out that H-protonic zeolites were not active for CO oxidation, and therefore CO 2 selectivity values were around 60-70% in the combustion of both chlorocarbons. However, the selectivity to carbon dioxide was considerably promoted when adding a noble metal [8]. Platinum-based catalysts resulted 100% selective to CO 2 whereas palladium-based ones showed lower selectivity values (80-90%) even at high temperatures.…”
