  • Publication number: 20070202034
    Abstract: Methods for the production of carbon foam from swelling coals that do not require the use of high process pressures, oxidized coal, devolatized coal, or high-strength, foam expansion confining molds are described. In some embodiments, a comminuted swelling bituminous coal is heated to a first elevated temperature sufficient to result in the coal particles softening and melting together to form a substantially homogeneous open cell plastic carbon material. The substantially homogeneous open cell plastic carbon material may then be heated to a second elevated temperature at a slow rate to form carbon foam. In some embodiments, the resulting carbon foam may be heated to a higher third elevated temperature. The resulting carbon foam may be subsequently heated to elevated temperatures as great as 3200° C. or more.

  • Publication number: 20070128102
    Abstract: The present invention includes methods for simultaneously producing, within a single container, two or more sections of high density carbon foam materials of defined shape. A method used to prepare high density carbon foam sections may involve heating a comminuted agglomerating bituminous coal bed, that is at least partially divided into two or more sections by the use of partitions within the coal bed, to an elevated temperature sufficient to result in the coal particles softening and melting together to form sections of a generally homogeneous, continuous, open cell carbon material. The sections of homogeneous open cell carbon material are then maintained at an elevated temperature for a period of time sufficient to substantially reduce or essentially eliminate the plastic properties of the bituminous coal. As desired, the resultant high density carbon foam sections may be cooled to essentially ambient temperatures or immediately or subsequently heated to elevated temperatures as great as about 3200° C.
