Patent number: 6699561Abstract: An activated carbon molded body, more particularly in honeycomb form and for use as an adsorption filter, can be produced from a mixture including activated carbon, water, novolak powder, clay, cellulose ether, liquid starch, wax, polyacrylamide and soap, by a procedure involving thoroughly mixing the constituents, extruding the mixture to form a monolithic molded body and cutting same to size, drying the body and effecting pyrolysis thereof. The adsorption filter produced therefrom can be regenerated by electrical heating under specified conditions.Type: GrantFiled: January 31, 2002Date of Patent: March 2, 2004Assignee: Helsa-Werke Helmut Sandler GmbH & Co. KGInventor: Thomas Wolff

Patent number: 6429165Abstract: A polymer-bonded granular adsorptive, absorptive, chemisorptive, or catalytically active material and a process for producing molded bodies from this material. An objective was to develop a polymer-bonded granular adsorptive, absorptive, chemisorptive, or catalytically active material which is capable of forming an open-pore and sorptive foamed body at increased temperatures while not reducing the specific surface of the active material and with a binding effect only during the mixing and processing phases, as well as a process for producing molded bodies from this material. This objective was met by mixing and processing an adsorptive, absorptive, chemisorptive, or catalytically active fine-grained material together with a finely particulate, meltable polyethylene with the addition of a binding agent having an oligocondensate basis.Type: GrantFiled: October 27, 1999Date of Patent: August 6, 2002Assignee: Auergesellschaft GmbHInventors: Rudolf Nastke, Gerald Rafler, Helmut Remde, Thomas Krugerke, Gabriele Stadermann, Jannett Kohls, Martin Kurth, Dieter Lubkoll
