摘要： Mesoporous carbon and method of making involves forming a mixture of a high carbon-yielding carbon precursor that when carbonized yields greater than about 40% carbon on a cured basis, and an additive that can be catalyst metal and/or low carbon-yielding carbon precursor that when carbonized yields no greater than about 40% by weight carbon on a cured basis. When a catalyst metal is used, the amount of catalyst metal after the subsequent carbonization step is no greater than about 1 wt. % based on the carbon. The mixture is cured, and the carbon precursors are carbonized and activated to produce mesoporous activated carbon.

摘要： Carbon monolith-supported catalysts with high leach resistance used in catalytic applications involving strong acidic and basic conditions in a pH range of from 0 to 6.5 and from 7.5 to 14, are respectively described. The leach resistance of the catalyst system originates from strong interaction between the catalyst and the unsaturated valence of the carbon surface. In addition to surprisingly high resistance to leach out, the catalysts also have substantial differential advantages in catalyst performance: catalyst activity, selectivity, and stability.

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.
