Title
(EN) METHOD OF MAKING A CARBON FOAM MATERIAL AND RESULTANT PRODUCT
(FR) PROCEDE DE FABRICATION D'UN MATERIAU DE MOUSSE DE CARBONE ET PRODUIT RESULTANT
Abstract
(EN)
A method of making anisotropic carbon foam material includes deashing and hydrogenating bituminous coal, separating asphaltenes from oils contained in the coke precursor, coking the material to create a carbon foam. In one embodiment of the invention, the carbon foam is subsequently graphitized. The pores within the foam material are preferably generally of equal size. The pore size and carbon foam material density may be controlled by (a) altering the percentage volatiles contained within the asphaltenes to be coked, (b) mixing the asphaltenes with different coking precursors which are isotropic in nature, or (c) modifying the pressure under which coking is effected. In another embodiment of the invention, solvent separation is employed on raw bituminous coal and an isotropic carbon foam is provided. A related carbon foam product is disclosed. The carbon foam materials of the present invention are characterized by having high compressive strength as compared with prior known carbon foam materials. A further embodiment is disclosed wherein a petroleum pitch is employed as the feedstock either alone or in combination with a coal feedstock.

L'invention concerne un procédé de fabrication d'un matériau de mousse de carbone anisotropique. Ce procédé consiste à décendrer et hydrogéner de la houille, à séparer les asphaltènes des huiles contenues dans un précurseur de coke, puis à cokéfier le matériau de façon à obtenir une mousse de carbone. Dans un mode de réalisation de l'invention, la mousse de carbone est ensuite graphitisée. De manière générale, les pores de ce matériau de mousse présentent de préférence une dimension égale. La dimension des pores et la densité de ce matériau de mousse de carbone peuvent être régulées (a) par modification du pourcentage d'éléments volatils contenus dans les asphaltènes à cokéfier, (b) par mélange des asphaltènes avec différents précurseurs de cokéfaction de nature isotropique, ou (c) par modification de la pression à laquelle on réalise la cokéfaction. Dans un autre mode de réalisation de l'invention, on opère une séparation de solvants sur la houille brute de façon à obtenir une mousse de carbone isotropique. L'invention se rapporte en outre à un produit de mousse de carbone résultant. Les matériaux de mousse de carbone de la présente invention sont caractérisés en ce qu'ils présentent un résistance à la compression élevée par comparaison avec les matériaux de mousse de carbone antérieurs. Dans un dernier mode de réalisation, un brai de pétrole est utilisé comme charge d'alimentation de manière isolée ou en combinaison avec une charge d'alimentation de houille.
