The invention concerns activated carbons. It further concerns a method for obtaining said activated carbons from a partly mesophased and partly mesogenic pitch. It concerns a method for obtaining activated carbons from a partly mesophase and partly mesogenic pitch containing less than about 40 % of type .alpha. resins, more than about 40 % of type .beta. resins and between about 5 and 30 % of type .gamma. resins by activating said pitch preceded by its optional carbonization.
La présente invention est relative à des charbons actifs. Elle a en outre pour objet un procédé d'obtention de ces charbons actifs à partir d'un brai partiellement mésophasé et partiellement mésogéné. Elle est relative à un procédé d'obtention de charbons actifs à partir d'un brai partiellement mésophasé et partiellement mésogéné contenant moins d'environ 40% de résines de type .alpha., plus d'environ 40% de résines de type .beta. et entre environ 5 et 30% de résines de type .gamma. par activation dudit brai éventuellement précédée par sa carbonisation.
