PURPOSE:To reduce the discharge amount of HC and CO in exhaust gas to the atmosphere to a large extent by arranging a main monolithic catalyst and a honeycomb heater formed by providing a current supply electrode to a honeycomb structure having many through-holes to the exhaust gas passage of a car, and further arranging an adsorbing material containing high silica zeolite thereto. CONSTITUTION:An adsorbing material for decontaminating the exhaust gas of a car containing high silica zeolite whose Si/Al ratio is 4.0 or more is prepared. A main monolithic catalyst and a honeycomb heater formed by providing at least two current supply electrode to a honeycomb structure having many through-holes are arranged to the exhaust gas passage of a car and the adsorbing material base on high silica zeolite is further arranged. As a result, the adsorbing material excellent in heat resistance can be obtained. By the adsorbing effect due to zeolite and the heat generating effect due to the supply of a current to the heater, the purification of HC and CO in exhaust gas can largely be improved and the discharge amount of HC and CO to the atmosphere can be reduced to a large extent. |
