ENHANCED METHANE FORMATION IN REFORMING CATALYSTS

Catalyst compositions suitable for use in the exhaust gas recycle stream of an internal combustion engine are provided. Such catalyst compositions typically provide significant amounts of methane in addition to syngas. A reformer incorporating such a catalyst for use in an exhaust gas recycle portio...

Zusammenfassung:	Catalyst compositions suitable for use in the exhaust gas recycle stream of an internal combustion engine are provided. Such catalyst compositions typically provide significant amounts of methane in addition to syngas. A reformer incorporating such a catalyst for use in an exhaust gas recycle portion of an internal combustion engine powertrain is described. A powertrain incorporating such a reformer, a method of increasing the octane rating of an exhaust gas recycle stream, and and a method of operating an internal combustion engine using methane-assisted combustion are also described. L'invention concerne des compositions catalytiques appropriées pour une utilisation dans le flux de recyclage de gaz d'échappement d'un moteur à combustion interne. Ces compositions catalytiques fournissent de manière caractéristique des quantités significatives de méthane en plus du gaz de synthèse. Un reformeur incorporant un tel catalyseur pour une utilisation dans la partie de recyclage d'un gaz d'échappement d'un groupe motopropulseur d'un moteur à combustion interne est décrit. Un groupe motopropulseur incorporant un tel reformeur, un procédé d'augmentation de l'indice d'octane d'un flux de recyclage de gaz d'échappement et un procédé de fonctionnement d'un moteur à combustion interne utilisant une combustion assistée par méthane sont également décrits.
