Patent number: 8034321Abstract: A method is described for producing a hydrogen-containing gas mixture from a suitable hydrocarbon-containing feed gas in a reformer, wherein at least part of the feed gas is diverted before it enters the reformer and is supplied to at least one secondary reformer, and wherein the feed gas is contacted with a nanostructured catalyst in the secondary reformer and the substantially CO and CO2 -free exhaust gases of the secondary reformer are either combined with the hydrogen-containing gas mixture which escapes the reformer or introduced into the reformer. 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: 7384668Abstract: The invention relates to a CCVD method for producing tubular carbon nanofibers on a support by catalytically depositing carbon out of the vapor phase. The inventive method is characterized in that a catalyst layer, which is deposited without current and which is based on nickel or cobalt, is applied to the support at least in places. Said catalyst layer is thermally activated before depositing carbon out of the vapor phase in a reducing atmosphere.Type: GrantFiled: February 12, 2002Date of Patent: June 10, 2008Assignee: Electrovac, Fabrikation Elektrotechnischer Spezialartikel Gesellschraft m.b.H.Inventors: Klaus Mauthner, Erich Leister, Ernst Hammel

Patent number: 7033650Abstract: In a method of producing a nanotube layer on a substrate by using a CVD process, the substrate is placed in a reaction chamber, which is flushed with a carbon-containing gas. Subsequently, the substrate is heated by an induction process to a temperature at which carbon from the gas phase is deposited on the substrate while forming nanotubes thereon.Type: GrantFiled: March 20, 2002Date of Patent: April 25, 2006Assignee: Electrovac, Fabrikation, Elektrotechnischer Spezialartikel, Gesellschaft mbHInventors: Klaus Mauthner, Xinhe Tang, Roland Haubner

Publication number: 20050049355Abstract: A flame retardant composite and a method for its fabrication are disclosed. The flame retardant composite shows both improved mechanical properties and flame retardancy. The composite comprises a matrix material and carbon nanotubes, such as single walled nanotubes, multi-walled nanotubes or fishbone-like graphitic cylinders, exhibiting a hollow core. For example, the outer diameters of the carbon nanofibers may be in the range from 1.2 to 500 nm. For example, a carbon nanotube may be incorporated as a layer in or on the surface of the composite. The method of fabrication of the composite may include a step of de-agglomeration.Type: ApplicationFiled: August 20, 2004Publication date: March 3, 2005Inventors: Xinhe Tang, Klaus Mauthner, Ernst Hammel
