An activated carbon body having flow-through channels and method of making the body. The method involves combining and shaping channel-forming material and optionally fugitive pore-forming material and non-fugitive support material and a crosslinkable resin into a green body and curing the resin. The temperature at which the channel-forming material begins to distort is greater than the curing temperature of the resin. The resin is carbonized and at the same time the channel-forming material is vaporized out to form a carbon body having flow through channels in the configuration of the fugitive material. The carbon body is then activated. Among other shapes the channels can be straight, curved or crisscrossed.
Corps de carbone activé possédant des canaux de circulation et méthode d'obtention, consistant à combiner et à mettre en forme des matières générant des canaux, et facultativement une matìère fugace formant des pores, ainsi qu'une matière de support non fugace et une résine réticulable, en un corps vert, et à réticuler la résine. La température à laquelle la matière générant les canaux commence à se déformer est supérieure à la température de réticulation de la résine. La résine est carbonisée et la matière générant les canaux est simultanément vaporisée pour former le corps de carbone possédant les canaux de circulation dans la configuration de la matière fugace. Le corps de carbone est ensuite activé. Les canaux peuvent être droits, courbes, entrelacés, etc.
