Patent number: 8003565Abstract: A method and catalysts for producing a hydrogen-rich syngas are disclosed. According to the method a CO-containing gas contacts a water gas shift (WGS) catalyst, optionally in the presence of water, preferably at a temperature of less than about 450° C. to produce a hydrogen-rich gas, such as a hydrogen-rich syngas. Also disclosed is a water gas shift catalyst formulated from: a) Pt, its oxides or mixtures thereof; b) Ru, its oxides or mixtures thereof; and c) at least one of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, V, Mo, Mn, Fe, Co, Rh, Ir, Ge, Sn, Sb, La, Ce, Pr, Sm, and Eu. Another disclosed catalyst formulation comprises Pt, its oxides or mixtures thereof; Ru, its oxides or mixtures thereof; Co, its oxides or mixtures thereof; and at least one of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Sc, Y, Ti, Zr, V, Mo, Mn, Fe, Rh, Ir, Ge, Sn, Sb, La, Ce, Pr, Sm, and Eu, their oxides and mixtures thereof.Type: GrantFiled: April 28, 2006Date of Patent: August 23, 2011Assignees: Honda Giken Kogyo Kabushiki Kaisha, Freeslate, Inc.Inventors: Alfred Hagemeyer, Raymond E.

Publication number: 20110197763Abstract: The invention concerns materials for eliminating oxides of nitrogen NO and NO2 present in exhaust gases, in particular from the internal combustion engines of automotive vehicles operating in a medium which is super-stoichiometric in oxidising agents, which can adsorb oxides of nitrogen then desorb the oxides of nitrogen by elevating the temperature with respect to the adsorption temperature or by passage of a rich mixture, said materials comprising mixed oxides the metals of which are in octahedral coordination, with the octahedra connecting together so that the structure generates lamellae. Said materials adsorb oxides of nitrogen by insertion and do not become poisoned in contact with oxides of sulphur and carbon contained in the gases. In the presence of a group VIII metal, said materials are capable of eliminating oxides of nitrogen adsorbed by reduction during the passage of a rich mixture.Type: ApplicationFiled: July 24, 2002Publication date: August 18, 2011Inventors: Thierry Becue, Philippe Villeret

Patent number: 7981836Abstract: The hydrothermal stability of transition aluminas used as adsorbents and catalyst carriers is improved through their treatment with a soluble silicon inorganic compound such as sodium silicate wherein the silicon compound is mixed with the alumina powder at the production stage of forming particulates by liquid addition. The silicon containing particulates are activated by heating at a temperature lower than 500° C. and treated, before or after the thermal activation, by a colloidal silica solution to produce a hydrothermally stable, low dust alumina. The total silica content of the final product is typically less than 5 mass-%.Type: GrantFiled: May 24, 2006Date of Patent: July 19, 2011Assignee: UOP LLCInventors: Vladislav I.
