Patent number: 7850929Abstract: An internal static mixing system such as a disperser of mesh wire or expanded metal co-knit with a multi filament material selected from inert polymers, catalytic polymers, catalytic metals or mixtures in combination with a vertical reactor having a reaction zone and the disperser disposed in said reaction zone, particularly for carrying out paraffin alkylation using acid catalyst is disclosed. The wire mesh provides the structural integrity of the system as well as the open space required in reactors for the movement of vapors and liquids though the system. The disperser may be in sheets, bundles or bales or positioned within a frame.Type: GrantFiled: June 28, 2006Date of Patent: December 14, 2010Assignee: Catalytic Distillation TechnologiesInventors: Lawrence A. Smith, Jr., Abraham P. Gelbein, John R. Adams

Patent number: 7842260Abstract: Provided is a reaction vessel for a fuel cell, and more particularly to a reaction vessel exhibiting improved thermal efficiency, and a reaction device for a steam reforming reaction for a fuel cell. The reaction device includes a cylindrical reaction catalyst chamber on which a target reaction catalyst for a predetermined target reaction is disposed; and a tubular oxidation catalyst chamber surrounding the reaction catalyst chamber, comprising an oxidation reaction catalyst therein. The reaction device according features an increased contact area between catalyst and gas, and rapidly heating of the gas in contact with the catalyst to a desired reaction temperature.Type: GrantFiled: October 23, 2007Date of Patent: November 30, 2010Assignee: Samsung SDI Co. Ltd.Inventors: Sung-chul Lee, Ju-yong Kim, Yong-kul Lee, Man-seok Han, Jun-sic Kim, Chan-ho Lee, Jin-goo Ahn
