Title
(EN) FUEL HIGH TEMPERATURE ANTIOXIDANT ADDITIVE
(FR) ADDITIF ANTIOXYDANT POUR CARBURANT À HAUTE TEMPÉRATURE
Abstract
(EN)
High temperature antioxidant additives and methods that improve a liquid fuel composition's thermal oxidative stability are disclosed. A liquid fuel composition may comprise a liquid fuel and a high temperature antioxidant additive. The high temperature antioxidant additive may comprise an aromatic carbocyclic ring that is monocyclic and comprises substituents comprising a hydroxyl group and an iminomethyl group positioned in an ortho relationship.
(FR)
L'invention concerne des additifs antioxydants à haute température et des procédés qui améliorent la stabilité oxydative thermique d'une composition de carburant liquide. Une composition de carburant liquide peut comprendre un carburant liquide et un additif antioxydant à haute température. L'additif antioxydant à haute température peut comprendre un noyau carbocyclique aromatique qui est monocyclique et qui comprend des substituants comprenant un groupe hydroxyle et un groupe iminométhyle positionnés selon une relation ortho.
