SHAPED WOOD-BASED ACTIVE CARBON of the Invention A shaped activated wood-based carbon with essentially no pore volume in pores greater than one micron in diameter and a higher apparent density is prepared from an active granular wood-based carbon with a significant pore volume in pores greater than one micron in diameter and a lower apparent density by the invention process of grinding the active granular wood-based carbon to a fine powder, mixing the ground carbon with a liquid selected from water or other polar molecule and a bentonite clay binder, shaping the mixture, drying the shaped active carbon to remove the liquid, and heat-treating the dried product to calcine, or fix, the clay binder. |
