摘要

This paper concerns the incineration of isopropyl alcohol (IPA) using the ferrospinel catalyst MnFe_2O_4. 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 [Fe_3O_4]). 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 (O_2) content of 21%, 1700 ppm of IPA, and a reaction temperature of 200℃.
