Patent

CA 2662765

A fuel additive composition includes: a) a reverse-micellar composition having an aqueous disperse phase that includes cerium dioxide nanoparticles in a continuous phase that includes a hydrocarbon liquid, a surfactant, and optionally a co-surfactant and b) a reverse micellar composition having an aqueous disperse phase that includes a cetane improver effective for improving engine power during fuel combustion. A method of making a cerium-containing fuel additive includes the steps of: a) providing a mixture of a nonpolar solvent, a surfactant, and a co-surfactant; and b) combining the mixture with an aqueous suspension of stabilized cerium dioxide nanoparticles.

L'invention concerne une composition d'additif pour carburant, comprenant : a) une composition micellaire inverse avec une phase aqueuse dispersée comprenant des nanoparticules de dioxyde de cérium dans une phase continue comprenant un liquide hydrocarboné, un tensioactif et éventuellement un cotensioactif et b) une composition micellaire inverse ayant une phase aqueuse dispersée comprenant un agent d'amélioration de l'indice de cétane efficace pour améliorer la puissance du moteur lors de la combustion du carburant. L'invention concerne également un procédé de fabrication d'un additif de carburant contenant du cérium comprenant les étapes consistant à : a) utiliser un mélange d'un solvant non polaire, d'un tensioactif et d'un cotensioactif ; et b) combiner le mélange avec une suspension aqueuse de nanoparticules de dioxyde de cérium stabilisée.
