Abstract
A catalytic converter for use in an automobile exhaust gas system suitable for use with an alcohol-containing fuel is provided. Preferably, the catalytic converter contains a palladium-impregnated ceramic honeycomb monolith disposed upstream of a platinum/rhodium-impregnated ceramic honeycomb monolith relative to the exhaust gas flow, such that the exhaust gas contacts the palladium-impregnated monolith before contacting the platinum/rhodium-impregnated monolith.
