When the low melting Group 1 metals are absorbed into the porous metal oxide at about 150° C., an exothermic reaction produces Stage I material, loose black powders that are stable in dry air. Further heating forms higher stage materials of unknown composition.Type: GrantFiled: July 8, 2009Date of Patent: October 26, 2010Assignees: Signa Chemistry, Inc., Board of Trustees of Michigan State UniversityInventors: Michael Lefenfeld, James L.

Publication number: 20100248950Abstract: A method for making an inorganic oxide supported catalyst involves impregnating an inorganic oxide component with a catalytic metal using an aqueous, acid bath. More specifically, the method involves forming and washing an inorganic oxide component, such as a silica gel or a silica co-gel, for example a silica-zirconia co-gel. The washed inorganic oxide component is then contacted with the acidic bath to effect the impregnation with the catalytic metal, such as cesium, to form an activated inorganic oxide component. Subsequently, the activated component is dried to form the catalyst. The resulting catalysts possess increased surface area, which is beneficial with respect to accessibility and amount of catalytically active sites.Type: ApplicationFiled: July 4, 2008Publication date: September 30, 2010Inventor: Heiko Morell
