Abstract
Un matériau adsorbant à base de graphène est intégré dans un épurateur formant une partie d'un adsorbeur ou relié à un orifice de purge de l'adsorbeur dans le système de gestion des vapeurs de carburant. Le matériau adsorbant est spécifiquement adsorbant d'hydrocarbures vaporisées pour empêcher des émissions de vapeurs de purge tout en produisant également des restrictions de débits faibles. L'adsorbant en graphène se présente sous la forme d'un dérivé de graphène activé et d'un polymère extrudé selon un modèle de conception en nid d'abeilles pour engendrer une pluralité de passages pour le flux des vapeurs. L'épurateur est relié à l'orifice de purge de l'adsorbeur de vapeurs de carburant et intègre un élément épurateur présentant une structure extrudée en nid d'abeilles ayant une quelconque combinaison de dérivés de graphène activés, de lignocellulose, de charbon de bois, de céramique, de liant et de flux.
