Publication number: 20200398254Abstract: 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.Type: ApplicationFiled: June 30, 2020Publication date: December 24, 2020Inventors: Jason MAZZOCCOLI, Walter G.

Patent number: 6534442Abstract: 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 500° C. The resulting char is next heated to temperatures greater than 500° C and subsequently activated with H2O, CO2, or O2, 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, SOX, NOX, and chloramines in liquid and/or gaseous media.Type: GrantFiled: July 16, 1999Date of Patent: March 18, 2003Assignee: Caigon Carbon CorporationInventors: Robert H. Vaughn, Keith R. Nicholson, Toan P. Vo

Patent number: 4095545Abstract: An improved self-propelled floating dredging apparatus including a buoyant hull structure carrying a pilot house and engine compartment. The buoyant hull comprises a pair of longitudinally aligned parallel pontoons to provide flotation. A rigid boom structure extends forwardly from the medial portion of the hull structure and is adapted to pivot about a horizontal axis, from a horizontal position to a submerged position, in response to the action of a pair of power cylinders and an interconnecting linkage. A diesel engine in the engine compartment drives a centrifugal dredging pump and a hydraulic fluid pump. A hydraulically driven, steerable water jet propulsion assembly is mounted on a transom at the aft end portion of the hull structure. A hydraulically driven cable winch mechanism is also mounted on the hull structure.Type: GrantFiled: March 2, 1977Date of Patent: June 20, 1978Assignee: VMI, Inc.Inventors: Robert H. Vaughn, C.
