Abstract

In this work the effect of microwave irradiation on the regeneration of soot-loaded uncatalytic and catalytic ceramic foam filters was studied for two different catalytic filter formulations. Combining dielectric permittivity and catalytic activity of the foam filter components with microwave absorbing properties of soot allowed a more effective filter regeneration. Moreover, iron based catalysts, typically not active towards soot oxidation in case of electrical heating, showed a significant activity in the presence of microwave.
