Abstract: A method of making anisotropic carbon foam material includes de-ashing 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.

In another embodiment of the invention, solvent separation is employed on raw bituminous coal and an isotropic carbon foam is provided. The carbon foam materials of the present invention are characterized by having high compressive strength as compared with prior known carbon foam materials.
