| Abstract: | Abstract This paper concerns the incineration of isopropyl alcohol (IPA) using the ferrospinel catalyst MnFe2O4. It covers the preparation of the ferrospinel catalyst, the screening of catalytic activity, catalytic incineration testing, and 72-hr decay testing of the catalyst. The experimental results of catalyst screening reveal that the Mn/Fe catalyst is the best of five prepared catalysts (chromium/iron Cr/Fe], manganese/iron Mn/Fe], zinc/iron Zn/Fe], nickel/iron Ni/Fe], and pure magnetite Fe3O4]). In tests of the catalytic incineration system used to convert IPA, 98% conversion was obtained at a space velocity of 24,000 hr?1, an oxygen (O2) content of 21%, 1700 ppm of IPA, and a reaction temperature of 200 °C. |
