<p>A method for the manufacture of coal-based carbon foams from a coal particulate starting material that comprises blending from 1 to about 10% by weight of pitch with the coal particulate before foaming. Blends of coal-based particulate with 1 to about 10% by weight of pitch as well as coal-based carbon foams manufactured from such blends are also described. Mold (12) is assembled from three individual pieces carbon or tool steel pieces, sides (12A) and (12B) and bottom (12C), all joined together by bolts (11) and lined with a ceramic glaze or spray applied ceramic lining (13). Cover (16) includes a similar interior ceramic lining 15 and is attached to sides (12A) and (12B) with bolts (11) in the final assembly prior to heating. Gaskets (19) are preferably used to insure a tight fit of cover (16) onto sides (12A) and (12B). Cover (16) is optionally equipped with a sintered vent plug (20) to permit purging of the interior of mold (12) with non-oxidizing gas.</p> |
