摘要：NOVELTY - A low-temperature catalytic combustion method for removing chlorine (Cl)-containing volatile organic compounds, comprises taking titanium oxide loaded vanadium oxide as catalyst, sending air treated as the oxidant into a reactor so that the organic compounds are completely combusted with the catalyst to convert the organic compounds as carbon oxide, hydrogen chloride and chlorines, and further discharging the combusted tail gas after being absorbed by diluted aqueous alkali (acid gas such as hydrogen chloride/chlorines). USE - Low-temperature catalytic combustion method for removing Cl-containing volatile organic compounds, particularly Cl-containing volatile Sundex (RTM: aromatic hydrocarbon compounds), in industrial waste gas, wastes and wastewater. ADVANTAGE - The method has high catalyst activity, strong chlorine poisoning resistance and lone catalyst service, is by-product free and secondary pollution free, and is suitable for removing halogen-containing organic compounds in a low-temperature catalytic combustion way. DETAILED DESCRIPTION - A low-temperature catalytic combustion method for removing Cl-containing volatile organic compounds, comprises taking titanium oxide loaded vanadium oxide as catalyst, sending air treated as the oxidant into a reactor so that the organic compounds are completely combusted with the catalyst to convert the organic compounds as carbon oxide, hydrogen chloride and chlorines, and further discharging the combusted tail gas after being absorbed by diluted aqueous alkali (acid gas such as hydrogen chloride/chlorines). The reaction pressure is 0.1-1 (preferably 0.1) MPa, and the temperature is 100-400 (preferably 250) degrees C. The catalyst amount is enough so that organic compounds are converted to carbon dioxide and hydrogen chloride in wet air atmosphere. The concentration of pollutant of the organic compounds is 0.05-5 vol.% and the waste gas process amount of per gram of catalyst is 10-30 L/hour. The catalyst comprises titanium oxide loaded vanadium oxide, where the content of vanadium oxide is 1-10 wt.% and the rest is titanium oxide.
