ABSTRACT:
This invention provides a gas engine in which a natural gas reforming apparatus for thermally decomposing CH.sub.4 in a natural gas into a reformed fuel of CO and H.sub.2 is used to improve the thermal efficiency, CO.sub.2 in an exhaust gas being used for the thermal decomposition operation to reduce the CO.sub.2 content of the discharged exhaust gas and minimize the generation of NOx. An oxygen eliminating apparatus for removing O.sub.2 from CO.sub.2 separated from the exhaust gas can be provided in the natural gas reforming apparatus. In this natural gas reforming apparatus, a gas fuel case in which a gas fuel flows is provided on the outer side of an exhaust gas passage body in which the exhaust gas flows, and a surface of a porous member provided in the gas fuel case is coated with a catalyst. The oxygen eliminating apparatus comprises a porous carbon member provided in a CO.sub.2 passage so as to subject O.sub.2 in CO.sub.2 and C to a reaction and convert the same substances into CO and CO.sub.2, and a power source for electrically heating the porous carbon member.
