In one embodiment, the present invention relates to a process for the formation of a CO2-selective absorption material that comprises providing a solid material, providing an amine source, contacting the solid material with the amine source to absorb amine molecules on the surface of the solid material, and contacting the absorbing amine molecules on the solid material surface with a CO2 stream such that upon contact with the amine and the solid material, CO2 binds with the amine functional group of the amine molecule, reducing the potential for the interaction of the amine functional group with the solid surface and increasing amine sites available for CO2 capture.Type: ApplicationFiled: November 7, 2008Publication date: October 21, 2010Applicant: THE UNIVERSITY OF AKRONInventor: Steven Chuang

Publication number: 20100248941Abstract: A regenerable sorbent for the removal of acid gas from a fluid stream. The regenerable sorbent is made from raw materials such as iron mineral, expansive clay and starch. Acid gas is removed from the fluid stream by a process where the raw materials are obtained, crushed, sifted, possibly pelletized, calcined and contacted with the fluid stream containing the acid gas.Type: ApplicationFiled: March 31, 2009Publication date: September 30, 2010Applicant: INTEVEP, S.A.Inventors: Alfredo Viloria, Monica Roman, Marvin Ricaurte, Yanine Gonzalez, Rafael Yoll, Marcos Rosa-Brussin

Publication number: 20100197956Abstract: A shell catalyst for the production of vinyl acetate monomer (VAM), comprising a porous catalyst support based on a natural sheet silicate, in particular based on an acid-treated calcined bentonite, said catalyst support being loaded with Pd and Au and being designed as a shaped body. In order to provide a shell catalyst for the production of VAM, which shell catalyst is characterized by a relatively high VAM selectivity and also a high activity, it is proposed that the catalyst support has a surface area of less than 130 m2/g.Type: ApplicationFiled: May 30, 2008Publication date: August 5, 2010Applicant: SUD-CHEMIE AGInventors: Alfred Hagemeyer, Gerhard Mestl, Peter Scheck, Alice Kyriopoulos
