| Summary: | A Co-MgAlO mixed oxide with 20 at % Co obtained from a layered double hydroxide (LDH) precursor was synthesized and its activity has been studied in the catalytic combustion of the methyl isobutyl ketone (MIBK). The characterization of the catalyst was performed by XRD, EDX and nitrogen adsorption. Its catalytic activity was evaluated in a fixed-bed continuous flow reactor in operating conditions typical for depollution applications, in the temperature range 100 - 400 °C and compared with MgAlO free of Co support and Co3O4. A reasonable good activity for the synthesized material at relatively low temperature was found. The catalyst was further subjected to a kinetic study in order to identify the temperature and composition dependencies of the combustion rate. |
