A fresh resistively heated catalytic converter was furnished by Kemira Oy to the U.S. Environmental Protection Agency (EPA) for evaluation on a methanol-fueled vehicle. This converter substrate was constructed from metallic foil and was considerably smaller in volume than three-way catalysts found on most late model U.S. automobiles. The Kemira Oy converter is referred to hereafter as an electrically heated catalyst (EHC). The EHC was evaluated in four separate modes. First, this catalyst was placed on an M100 (neat methanol) fueled vehicle and emission tested without resistive heating or catalyst air assist. The EHC was then tested using resistive heating, but with no air assist provided during the period of heating. A catalyst operating mode utilizing both resistive heating and air assist was evaluated next. Finally, a larger catalyzed ceramic monolith was added behind the EHC as a main catalyst. This two-catalyst system was then evaluated, with resistive heating and catalyst air assist applied to the upstream EHC.
