Patent number: 6472343Abstract: A new shaped activated carbon and the method of its manufacture are disclosed. The invention resides in the crosslinking of a polymeric cellulose, such as sodium carboxymethylcellulose (CMC), within the carbon bodies after they are shaped, employing the CMC as a binder for the activated carbon. The approach to attain product mechanical strength and water stability by crosslinking rather than high temperature heat treatment is not obvious from the prior art teaching. The crosslinking reaction occurs at temperatures below 270° C. In addition, this new binder technology produces shaped carbon bodies having key properties beyond the best level that has been accomplished with other binders.Type: GrantFiled: April 11, 2001Date of Patent: October 29, 2002Assignee: Westvaco CorporationInventors: Peter D. A. McCrae, Tiejun Zhang, David R. B. Walker

Patent number: 6465387Abstract: A method for preparing synthetic, semi-crystalline, porous inorganic oxide composition containing a reactive organic silane moiety which is on the surface of pore walls. The composition is prepared from a poly(oxyalkylene) based surfactant and a hydrolyzable organic silane. The surfactant is preferably a poly(ethylene) oxide, a poly(propylene) oxide polymer or mixtures thereof. The organic silane is preferably mercaptopropylsilane. The compositions are particularly useful as adsorbents, and catalysts.Type: GrantFiled: October 18, 2000Date of Patent: October 15, 2002Assignee: Board of Trustees of Michigan State UniversityInventors: Thomas J. Pinnavaia, Louis Mercier
