Abstract (EN): The catalytic oxidation of methyl-isobutyl-ketone (MIBK) in low concentration (1340 ppm) was investigated over a Pt/HFAU catalyst. Two main reactions were observed: total oxidation into CO2 and the formation of non-desorbed compounds ("coke"). The conversion into these products depends on the reaction temperature, high temperatures being favourable to the conversion into CO2 and unfavourable to the conversion into coke. Oscillations in the conversion into CO2 were observed at specific temperatures, which were explained by coke combustion.
