Zusammenfassung:	PROBLEM TO BE SOLVED: To purify an exhaust gas from a gas engine at high efficiency using a catalyst. SOLUTION: In removing hazardous components contained in the exhaust gas from a gas engine, the untreated exhaust gas passes through a catalyst after heating by a heating means 20 up to a temperature not lower than the temperature at which the catalyst in a catalyst bed 30 is active. Heat is exchanged between the treated high-temperature exhaust gas from the catalyst bed and the untreated low-temperature exhaust gas in a heat exchanger 10 to save an energy cost.
