Abstract

A green method for manufacturing CuFe 2 O 4 from industrial Cu sludge was successfully developed by a combination of acid leaching, chemical exchange and ferrite process. The CuFe 2 O 4 was applied for combustion of volatile organic compounds (VOCs) derived from isopropyl alcohol (IPA). The results show that IPA was reacted to form intermediate acetone and CO 2 at the temperature range of 110-170°C. When the temperature was increased to 180°C, IPA can be 100% converted into CO 2 . The 96-h decay tests indicated that the catalyst has a good thermal stability and durability under the conditions of gas hourly space velocity 30,000h -1 , oxygen content 21%, IPA inlet concentration 2000ppm, and reaction temperature 180°C. The results demonstrate great potential that our manufactured CuFe 2 O 4 catalyst can be used in combustion IPA streams to eliminate the emission of IPA.
