Furthermore there is described the use of this method for producing high quality soots, nanoonions, nanohorns, nanofibers and/or nanotubes which adhere to the catalyst, and a device for producing a hydrogen-containing gas mixture from a suitable feed gas in a reformer which comprises a supply line with a super-heated-vapor line joining said supply line, and a discharge line.Type: GrantFiled: January 23, 2006Date of Patent: October 11, 2011Assignee: Electrovac AGInventors: Klaus Mauthner, Ernst Hammel

Patent number: 7972394Abstract: A method of operating a methanation reactor to reduce carbon monoxide concentration in a reformate stream in a fuel cell reformer. The reactor includes a flowpath with a noble metal catalyst supported by a ceramic support such that the reactor preferentially converts carbon monoxide via methanation over that of carbon dioxide. The reduced level of carbon monoxide present in the reformate stream after passing through the methanation reactor reduces the likelihood of poisoning of the catalyst used on the fuel cell anode.Type: GrantFiled: August 11, 2006Date of Patent: July 5, 2011Assignee: GM Global Technology Operations LLCInventors: Mark Robert Feaviour, Julia Margaret Rowe

Patent number: 7951350Abstract: A process and system for producing an effluent gas containing carbon monoxide and hydrogen is presented. The process includes introducing a fuel gas including a hydrocarbon and a reformer gas into a reactor system. The reformer gas may include steam, CO2, or a mixture thereof. Under steam reforming temperatures and pressures, the gases are reacted in the presence of reactant solids. The reaction process produces a carbon monoxide and hydrogen containing effluent, which may be withdrawn from the reactor system.Type: GrantFiled: January 26, 2007Date of Patent: May 31, 2011Assignee: West Biofuels, LLCInventor: Donald Taylor

Patent number: 7846413Abstract: A process and a system are provided for producing and separating hydrogen and carbon dioxide from a hydrocarbon and steam. A hydrocarbon and steam are steam reformed and the reformed gas is shift reacted to produce a shift gas. Hydrogen is removed from the shift gas, and the hydrogen-depleted gas is reformed and shift reacted again to produce more hydrogen and carbon dioxide. The hydrogen and carbon dioxide are then separated.Type: GrantFiled: November 28, 2007Date of Patent: December 7, 2010Assignee: Shell Oil CompanyInventors: Lloyd Anthony Clomburg, Jr., Andreas Nicholas Matzakos, Peter Veenstra, Scott Lee Wellington

Publication number: 20100304236Abstract: The present invention generally relates to catalyst compositions comprising aluminates, such as nickel aluminates, and related methods. In some embodiments, the catalyst composition may be advantageously modified, for example, by the addition of one or more metal additives to further enhance catalyst performance. Such modifications can provide a more effective catalyst and can reduce the level of coking during catalytic processes. Some embodiments of the invention may provide effective catalyst compositions for steam reforming. In some cases, the catalyst composition may be utilized under relatively mild reaction conditions.Type: ApplicationFiled: February 28, 2008Publication date: December 2, 2010Applicant: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Jackie Y.

Patent number: 7842634Abstract: A useful partial oxidation catalyst element includes a catalyst component, a support component, and a substrate. The catalyst component is formed by combining a catalytically active metal with a first support material to form a mixture and calcining the mixture. The support component is formed by calcining a second support material, not containing the active metal. The first and second support materials include particles having an average particle diameter of less than 20 microns. A catalyst material is formed by combining the catalyst component and the support component, wherein the catalyst material contains less than 20% of the catalyst component by weight. The catalyst material is applied to a substrate configured for gas flow therethrough, thereby formulating the partial oxidation catalyst element. The partial oxidation catalyst element is especially useful for fuel reforming and fuel cell applications.Type: GrantFiled: September 11, 2006Date of Patent: November 30, 2010Assignee: Umicore AG & Co. KGInventors: Jeffrey G. Weissman, Ming-Cheng Wu

Patent number: 7776112Abstract: Methods, processes, and apparatuses for the production of hydrogen gases are provided. A catalytic amount of iodine is dissolved in a hydrocarbon fuel source, such as cyclopropane and/or benzene, and the mixture is heated to a temperature greater than about 80° C. A reaction vessel capable of maintaining pressures greater than 1 atmosphere is used. The hydrogen gas thus produced is recovered, and optionally purified. The hydrogen gas product can be delivered to a fuel cell stack. The fuel cell stack receives hydrogen gas from the reaction chamber and produces an electric current therefrom as the hydrogen gas is reacted with oxygen to form water.Type: GrantFiled: February 8, 2007Date of Patent: August 17, 2010Assignee: Honda Motor Co., Ltd.Inventor: Leonid Grigorian
