<P>PROBLEM TO BE SOLVED: To provide a device and a method for generating H<SB>2</SB>and CO in an O<SB>2</SB>-containing gas flow, and provide a device and a method for removing NO<SB>x</SB>from an O<SB>2</SB>-containing gas flow, particularly an oxygen-rich exhaust gas flow from a lean burn engine such as a diesel engine. <P>SOLUTION: The system includes a fuel injector 91 injecting fuel into an exhaust gas flow from the engine; a combustion apparatus 92 including an oxidation catalyst and receiving an exhaust gas flow together with fuel injected by the fuel injector 91; and a fuel combustion apparatus 94 including a fuel reforming catalyst and receiving the exhaust gas flow from the combustion apparatus 92. The combustion apparatus 92 is operated so as to burn a first portion of the injected fuel and vaporize other portions of the injected fuel, and the fuel combustion apparatus 94 is operated to form H2 and CO. <P>COPYRIGHT: (C)2009,JPO&INPIT |
