Patent number: 7578669Abstract: The present invention discloses a hybrid combustor, such as an anode tailgas oxidizer (ATO), for fuel processing applications which combines both flame and catalytic type burners. The hybrid combustor of the present invention combines the advantages of both flame and catalytic type burners. The flame burner component of the hybrid combustor is used during start-up for the preheating of the catalytic burner component. As soon as the catalytic burner bed is preheated or lit off, the flame burner will be shut off. Optionally, the hybrid combustor may also include an integrated heat recovery unit located downstream of the catalytic burner for steam generation and for the preheating of the feed for a reformer, such as an autothermal reformer.Type: GrantFiled: December 14, 2006Date of Patent: August 25, 2009Assignee: Texaco Inc.Inventors: Yunquan Liu, Curtis L. Krause, Kevin H. Nguyen

Patent number: 7490580Abstract: A vaporizer generates vapor by vaporizing a liquid. In particular, a vaporizer generates fuel vapor that is used for reforming fuel by vaporizing a liquid fuel that contains a hydrocarbon. This vaporizer includes a heating gas direct movement flow path along which a heating gas flows by moving directly in a horizontal direction; vaporization flow paths that are positioned such that they can exchange heat with the heating gas direct movement flow path, and that vaporizes liquid fuel; a fuel supply pipe that supplies the liquid fuel to the vaporization flow paths; and a vapor flow path that is positioned in an upstream portion on the heating gas direct movement flow path from the vaporization flow paths and that heat fuel vapor that is discharged from the vaporization flow paths.Type: GrantFiled: July 8, 2003Date of Patent: February 17, 2009Assignee: Honda Motor Co., Ltd.Inventors: Satoshi Hanai, Kiyoshi Kasahara, Yuuji Asano

Publication number: 20090000572Abstract: An apparatus and method for vaporizing liquid are provided which employ a plurality of rods disposed within a storage vessel that serve as the heat transfer element. While the plurality of rods are generally submerged by the liquid fuel to facilitate heat transfer and vaporization of the liquid fuel, the rods may be packed closely together such that the liquid inventory required to maintain the rods in a submerged state is substantially less than required by conventional fuel supply systems, thereby permitting the weight of a fuel supply system that incorporates the apparatus and method to be reduced while still permitting effective vaporization of the fuel.Type: ApplicationFiled: June 27, 2007Publication date: January 1, 2009Inventors: Alan Z.
