Abstract

In an electrically heated catalytic converter including a heater consisting of a structure having an open porosity so as to permit fluid to flow therethrough, a heterogeneous catalyst is disposed within the heater structure. The heater structure, which includes the catalyst, is capable of accommodating sufficient electrical energy to provide the activation energy required for a particular catalytic reaction to be performed by the catalytic converter.
