    摘要： An activated carbon catalyst having sulfur dispersed homogeneously thereon, the sulfur being chemically bonded to the activated carbon. A method of making the catalyst involves forming an intimate mixture of a synthetic carbon precursor and a sulfur-containing material, curing the carbon precursor, carbonizing the carbon precursor, activating the carbonized carbon precursor to produce an activated carbon catalyst having sulfur chemically bonded to said activated carbon and uniformly dispersed thereon.

    摘要： A method for making an activated carbon composite which involves providing a crosslinkable resin and a support material which is wettable by the resin. The support material can be cotton, chopped wood, sisal, non-fugitive material, and combinations of these. The support is contacted with the resin; and the resin and support material are dried. The resin and support material are then shaped, the resin is cured, and the resin and any carbonizable material are carbonized. The carbon is then activated to produce the product composite. An activated carbon composite produced by the above described method in which the carbon is in the form of a continuous structure reinforced by and uniformly distributed throughout non-fugitive support material.

    摘要： A system for adsorbing a plurality of contaminants from a workstream composed of a first stage open-ended activated carbon monolith adsorber, a second stage open ended activated carbon monolith adsorber downstream of the first stage. The first stage activated carbon has an average pore size that is larger than the average pore size of the second stage activated carbon. A method for removing more than one contaminant from a workstream which involves passing a workstream containing more than one contaminant through a first open ended activated carbon monolith adsorber having a pore size suitable for adsorbing the major portion of the larger size contaminant and for allowing the smaller size contaminant to pass through the monolith, to cause adsorption of the major portion of the larger size contaminant by the activated carbon, while allowing the smaller size contaminant to pass through the first monolith, and thereafter passing the effluent from the first adsorber through a second open ended activated carbon monolith adsorber having a pore size suitable for adsorbing the smaller size contaminant to cause adsorption of the major portion of the smaller size contaminant by the second monolith activated carbon. The adsorbed contaminants can then be desorbed by passing a regenerating stream(s) through the respective monoliths.
