US Patent:

6342129, Jan 29, 2002

Filed:

May 14, 1998

Appl. No.:

09/079424

Inventors:

Robert H. Vaughn - Bethel Park PA
Keith R. Nicholson - Munhall PA

Assignee:

Calgon Carbon Corporation - Pittsburgh PA

International Classification:

C01B 3102

US Classification:

20415747, 423445 R, 502423

Abstract:

A process is provided for the production of a catalytically-active carbonaceous char. By this process, a nitrogen-containing compound is combined with an uncarbonized nitrogen-poor carbon-containing material. The resulting mixture is then carbonized and oxidized at temperatures less than 600Â C. The resulting low-temperature char is next heated to temperatures greater than 600Â C. and subsequently activated with H O, CO , or O , singly or in any combination, to result in the catalytically-active carbonaceous char. The resulting catalytically-active carbonaceous char has utility for the chemical conversion of peroxides, hydrides, SO , NO , and chloramines in liquid and/or gaseous media.

Assignee:

Calgon Carbon Corporation - Pittsburgh PA

International Classification:

B01D 5356

US Classification:

4232391

Abstract:

An improved process is provided for the chemical conversion and removal of nitrogen oxides from gaseous streams containing a stoichiometric amount of ammonia by contacting a low temperature catalytically-active carbonaceous char with said gaseous stream. The invention provides for the use of a low temperature carbonaceous char capable of rapidly decomposing hydrogen peroxide in an aqueous solution.

Assignee:

Calgon Carbon Corporation - Pittsburgh PA

International Classification:

C07F 922

US Classification:

562 17

Abstract:

An improved process is provided for the manufacture of N-phosphonomethylglycine from N-phophonomethyliminodiacetic acid in the presence of a molecular-oxygen containing gas utilizing a catalytically active carbonaceous char produced at low temperature.

Abstract:

Sorbent materials are described that have enhanced performance in removing chlorine and chloramine, among other toxic compounds. The sorbent materials are formed by a process which includes steps of oxidation, adding a nitrogen-containing compound, and calcining the sorbent. The processes of forming the sorbent materials are also disclosed. The sorbent materials have excellent performance as measured by a chloramine and/or chlorine destruction number, and the sorbents retain a high nitrogen edge concentration. The sorbent materials may also be incorporated into devices such as filter assemblies.

Abstract:

Sorbent material sheets are wound around a center core of material that includes additional sorbent. This configuration further increases the packaging efficiency and performance of the sorbent material sheets as part of an overall housing or apparatus. In some embodiments, the sorbent material sheets are arranged in a stacked configuration. Configurations of the sorbent material sheets as part of a canister are also described.
