What is Catalytic oxidation of aliphatic chlorinated volatile organic compounds over Pt/H-BETA zeolite catalyst under dry and humid conditions about?
The present study investigated the applicability of noble metal/H-zeolite catalysts for the oxidative decomposition of chlorinated VOCs, and specifically compared the activity and selectivity of Pt/H-BETA with that of an H-BETA for the combustion of dichloromethane and trichloroethylene (1000 ppm in dry and humid air) between 200 and 550 8C at a space velocity of 15,000 h À1 . A preliminary study identified the superior catalytic properties of H-BETA as an eventual support for a supported noble metal catalyst compared to other conventional supports such as Al 2 O 3 , ZrO 2 and SiO 2 . The primary catalytic property for predicting activity in oxidative decomposition reactions was observed to be the total acidity of the support. Platinum played a major role in influencing the catalytic properties of H-BETA for complete oxidation of the chlorinated volatile organic compounds. Thus, the activity of the resultant Pt/H-BETA catalyst was noticeably enhanced, and the production of CO 2 and Cl 2 , the products of CO oxidation and the Deacon reaction, respectively, was largely favoured. The addition of 15,000 ppm of water was found to improve the performance of the Pt/H-BETA catalyst, since
