A process for removing color bodies from hydrocarbon-based fuels, particularly gasoline, using an activated carbon is disclosed. Color bodies are removed from the fuel by contacting the fuel with such activated carbon having within this pore structure a fuel decolorizing amount of polymerized phosphoric acid or reduced transition metals. Phosphoric acid may be added to a non-phosphoric acid-activated carbon (such as steam activated coal-based) prior to the subsequent heat treatment or one can take advantage of residual phosphoric acid present in, for example, a phosphoric acid-activated wood-based carbon. Similarly, transition metals such as copper may be added to an activated carbon in a salt form in addition to whatever is already present therein as impurities.

L'invention concerne un procédé pour éliminer des colorants dans des carburants à base d'hydrocarbures, en particulier de l'essence, au moyen d'un charbon actif. Des colorants sont éliminés du carburant par mise en contact du carburant avec ce charbon actif présentant, dans sa structure poreuse, une quantité d'acide phosphorique polymérisé ou de métal de transition réduit décolorant le carburant. L'acide phosphorique peut être ajouté à un charbon non activé par de l'acide phosphorique (tel qu'un charbon activé par de la vapeur) avant le traitement thermique ultérieur ou il possible de tirer avantage de l'acide phosphorique résiduel présent, par exemple, dans un charbon de bois activé par de l'acide phosphorique. De façon similaire, des métaux de transition, tels que le cuivre, peuvent être ajoutés à un charbon actif sous forme saline en plus de ceux déjà présents dans ce charbon sous forme d'impuretés.
