Beschreibung
Zusammenfassung:	An electrically heatable catalytic converter for the catalytic treatment of an exhaust gas in an exhaust-gas tract of an internal combustion engine is disclosed. The catalytic converter includes a first catalysis region for the catalytic treatment of the exhaust gas, and a second catalysis region is separate from the first catalysis region. The second catalysis region for the catalytic treatment of the exhaust gas is arranged downstream of the first catalysis region with a predetermined spacing to the first catalysis region. The catalytic converter includes an electric heating device through which the exhaust gas can flow. The electric heating device is arranged downstream of the first catalysis region and upstream of the second catalysis region and is designed to at least partially heat the first catalysis region and the second catalysis region.
