Study On Catalytic Combustion Of CVOCs Over Supported Catalysts

Chloride Volatile Organic Compounds (CVOCs) are the main sourceof air pollution, in chemical industry, organic waste gas containing chlorine is massively released into air as the intermediate and the by-product. The catalyzed combustion process is one of the most effective methods to treat CVOCs.The study is based on the metal oxide compound supported catalyst for CVOCs catalytic combustion. Two kinds of metal oxide compound supported catalysts, V₂O₅/Al₂O₃-potsherd catalyst and Cr₂O₃/Al₂O₃-potsherd catalyst, were prepared using impregnation method. Their catalytic combustion performance on methylene chloride and dichloroethane were tested using gas chromatography as the detector. Characteristic properties of the catalyst such as specific surface area and structure were measured using XRD, EDS, BET as well.The activity appraisal experiments indicated that both catalysts effectively catalized the combustion of methylene chloride and...
