Abstract: An adsorptive monolith made by extruding a mixture of activated carbon, a ceramic forming material, a flux material, and water, drying the extruded monolith, and firing the dried monolith at a temperature and for a time period sufficient to react the ceramic material together and form a ceramic matrix. The extrudable mixture may also comprise a wet binder. The monolith has a shape with at least one passage therethrough and desirably has a plurality of passages therethrough to form a honeycomb. The monolith may be dried by vacuum drying, freeze drying, or control humidity drying. The monolith is useful for removing volatile organic compounds and other chemical agents such as ozone from fluid streams. Particularly useful applications include adsorptive filters for removing ozone from xerographic devices and other appropriate office machines and volatile organic compounds from automobile engine air intake systems.

Abstract: An improved method of manufacturing hard activated carbon pellets is disclosed in which a lignocellulose material is chemically activated to form a char and heated to a temperature above about 360.degree. C. which char is ground and then agglomerated in a pin mixer followed by pelleting the agglomerated acid char in the presence of an activatable binder. The pelleted hard activated carbon is then subjected to a final heat activation to yield a product with high density and activity.

Abstract: A method of manufacturing hard pelleted activated carbon is disclosed in which pellets are first formed by agglomeration in a pin mixer followed by pelleting the plasticized acid char (without the use of additional binders), and then activating the carbon pellets to yield a product with high density and activity.

Abstract: 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.
