    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： 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 device for use in processing of a liquid and/or gas stream. The device is made up of a monolithic structure having active powder for treating streams. The structure has an inlet end and an outlet end and a multiplicity of cells extending from inlet end to outlet end. The cells are separated from one another by porous walls, a portion of the total number of cells being plugged in a pattern such that a stream enters the device through the unplugged cells at the inlet end and passes through at least two porous walls and the active powder in-between, and thereafter passes out of the device through unplugged cells at the outlet end. The device finds use in a number of applications including ion exchange, adsorption, biological and chemical reactions, and catalytic applications.

    摘要： A monolithic structure having active material that includes at least inorganic ion exchange material, for purifying a liquid stream of contaminants such as heavy metals, chlorine, volatile organics, pesticides, herbicides, and/or parasites, etc. The structure has an inlet end and an outlet end and a multiplicity of cells extending from inlet to outlet end. The cells are separated from one another by porous walls that are alternatively plugged at each end such that a liquid stream that enters the structure, enters through the unplugged cells at the inlet end and passes through porous walls to be purified by the active material, and thereafter passes out of the structure through unplugged cells at the outlet end. One method of making the structure involves applying active material as a coating on an alternately plugged substrate. The average particle size of the active material after calcination is greater than the average cell wall pore size of the substrate. The coated substrate is dried at no greater than 200° C., and calcined at no greater than 650° C., to bond the active material to the substrate. The structure can be shaped from a forming mixture of the active materials.
