23 Claims

1. A process for producing a carbon foam material, the process comprising:

a heating step comprising heating a homogeneous mixture of a coal material, at least one conductive carbon material, and a flux agent in a microwave heating apparatus, thereby forming the carbon foam material;

wherein the coal material has a particle size of between about 10 mesh and about 400 mesh;

wherein the coal material is present in an amount of from about 20 wt % to about 75 wt % based on the total weight of the mixture;

wherein the at least one conductive carbon material is present in an amount of from about 25 wt % to about 80 wt % based on the total weight of the mixture;

wherein the flux agent comprises a carbohydrate syrup; and

wherein the at least one conductive carbon material is capable of absorbing microwave radiation.
