Abstract

PURPOSE:To efficiently decompose exhaust gas by reacting water with activated magnetite to obtain hydrogen and alternately sending exhaust gas and this hydrogen into a magnetite contact passage held to a specific temp. range. CONSTITUTION:A chamber 9 having magnetite 70 received therein is heated by a heating device 40 to be held to about 300 deg.C and an electron is donated to this magnetite 70 to take an oxygen ion from said magnetite and the magnetite 70 is activated as oxygen deficient magnetite. Steam is sprayed to oxygen deficient magnetite to generate hydrogen and, when this hydrogen is supplied to an exhaust gas decomposing apparatus 3 held to about 250 350 deg.C, magnetite is changed to active magnetite. Next, exhaust gas is sent into the active magnetite from an engine 1. Whereupon, oxygen of carbon dioxide or NOx is taken in the oxygen deficient magnetite and chemical reaction is generated to purify the exhaust gas.
