A method, apparatus, and fuel composition for the protection of a catalytic after treatment system and a method for protecting a catalytic after treatment system in a low sulfur fuel system are discloseD. A scavenging agent is introduced into the base fuel in an amount effective to complex with catalytic poisoning combustion by products and reduce catalyst poisoning. In a preferred embodiment, the scavenger is an organometallic compound which also imparts additional desirable properties to the fuel.
L'invention concerne un procédé, un appareil et une composition combustible pour la protection d'un système de post-traitement catalytique dans un système d'alimentation en carburant à faible teneur en soufre. Selon cette invention, un épurateur, introduit dans le carburant de base dans une certaine proportion, se combine aux sous-produits de combustion nocive catalytique et réduit la pollution catalytique. Dans un mode de réalisation préféré, cet épurateur est un composé organométallique qui attribue au carburant des propriétés souhaitables supplémentaires.
