Abatement of volatile organic compounds in industrial gases is necessary in order to improve life environment, but it is desirable to minimaze the cost of the process. In our previous study we found high catalytic aktivity of the transition metal mixed oxides, calcined Co-Mn-Al LDH-like precursor, in total oxidation of ethanol. However, the concentration of the metals in such catalyst is high and a considerable part of the pellet volume is not utilized because of internal diffusion in the fast oxidation reaction. Therefore, we studied preparation of Co-Mn-Al mixed oxides catalysts over cordierite monoliths and examined their properties in comparison with properties of other catalysts prepared by pelletizing of precipitated LDH-like precursor, coating of preformed supports with catalyst precursor and impregnation of preformed supports with water solution of metal nitrates.
