Wall-flow catalytic filters were prepared by impregnation of porous cordierite honeycombs with Cs-Fe-V catalysts. The catalytic filters were tested at the exhaust of a gas-oil burner. Results reported indicate that the trapped soot begin to burn at a temperature around 300-320 degrees C allowing the self-regeneration of the filter. Performances were found to remain stable also under high SO(2) concentrations, making these catalytic filters suitable for soot removal in off-road diesel engines and domestic apparatus.

Abstract
Wall-flow catalytic filters were prepared by impregnation of porous cordierite honeycombs with Cs-Fe-V catalysts. The catalytic filters were tested at the exhaust of a gas-oil burner. Results reported indicate that the trapped soot begin to burn at a temperature around 300-320 degrees C allowing the self-regeneration of the filter. Performances were found to remain stable also under high SO(2) concentrations, making these catalytic filters suitable for soot removal in off-road diesel engines and domestic apparatus.
