Catalytic converter for use in automotive exhaust emission control
 A catalytic converter suitable for use in controlling automotive exhaust emissions including a honeycomb heater disposed downstream of a main monolithic catalyst or between main monolithic catalysts. The honeycomb heater includes a honeycomb structure with a catalyst carried thereon and with at least two electrodes provided thereon to supply a current thereto. A catalytic converter also includes a monolith catalyst for ignition which is disposed downstream of the honeycomb heater. A catalytic converter includes, in place of the honeycomb heater and the monolithic catalyst, a module which is composed of a catalyzed light-off honeycomb heater or of a honeycomb heater and a light-off monolithic catalyst. The module is removably disposed upstream or downstream of a main monolithic catalyst, or between main monolithic catalysts.
