<p>PURPOSE:To decompose exhaust gas while magnetite is continuously activated by sending the exhaust gas containing oxygen, carbon monoxide and nitrogen oxide into a reaction chamber having magnetite of predetermined temp. received therein. CONSTITUTION:A reaction chamber 3 is connected to the passage of the exhaust gas containing oxygen, carbon monoxide and nitrogen oxide from a diesel engine. The reaction chamber 3 is packed with magnetite 2 of an appropriate form and heated by a heater 1 so that the internal temp. thereof becomes about 300 deg.C. When the exhaust gas is sent into the reaction chamber 3 having magnetite 2 heated to about 300-600 deg.C received therein, oxygen can be removed. That is, oxygen in the exhaust gas is continuously removed and nitrogen oxide is efficiently decomposed to nitrogen gas and carbon dioxide can be decomposed in a post process by activated magnetite.</p> |
