Toluene Combustion over Metal Oxide Washcoated Monolithic Catalyst

Catalytic combustion of toluene over ceramic monolith supported Mn, Fe, Co, Cu and Zr oxide-based catalysts has been investigated. The catalysts were prepared by washcoating and characterized by Scanning Electron Microscopy (SEM) technique. The adhesion of the washcoat was evaluated using an ultrasonic technique. The increase in activity was followed by increasing metal oxide content. 6.5MnO(2)/CM (CM: ceramic monolith) catalyst exhibited the highest catalytic activity, over which the toluene conversion is up to 90 percent at a temperature of 291 degrees C.
