Publication number: 20210300799Abstract: An anode, a flow cell including the anode, and a method for electrocatalytic treatment of bio-oil and/or wastewater are disclosed. The anode comprises RuO2 particles on a titanium support. The method includes flowing a process stream through the flow cell in the absence of added hydrogen, at a temperature of 0° C. to 50° C. and atmospheric pressure, and applying a potential across the flow cell such that the anode is positive with respect to the cathode, thereby electrocatalytically oxidizing compounds in the process stream to produce a treated process stream at the anode and generating hydrogen gas as a byproduct at the cathode.Type: ApplicationFiled: March 26, 2021Publication date: September 30, 2021Applicant: Battelle Memorial InstituteInventors: Juan A. Lopez-Ruiz, Jonathan D. Egbert, Charles J. Freeman, Oliver Y. Gutiérrez Tinoco, Jamelyn D. Holladay, Daniel T. Howe, Yang Qiu, Ismael A. Rodriguez Perez

Patent number: 9121647Abstract: A system and method for storing cold energy are detailed. The system includes a solid refrigerant in a structured form that stores cold energy. Upon deformation, the solid refrigerant transforms into a high energy deformed state from a low energy non-deformed state. In the deformed state, the solid refrigerant stores cold energy that can be released to a desired location upon demand.Type: GrantFiled: March 30, 2011Date of Patent: September 1, 2015Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Jun Cui, Jamelyn D. Holladay

Patent number: 8889097Abstract: An on-board hydride storage system and process are described. The system includes a slurry storage system that includes a slurry reactor and a variable concentration slurry. In one preferred configuration, the storage system stores a slurry containing a hydride storage material in a carrier fluid at a first concentration of hydride solids. The slurry reactor receives the slurry containing a second concentration of the hydride storage material and releases hydrogen as a fuel to hydrogen-power devices and vehicles.Type: GrantFiled: January 9, 2012Date of Patent: November 18, 2014Assignee: Battelle Memorial InstituteInventors: Kriston P. Brooks, Jamelyn D. Holladay, Kevin L. Simmons, Darrell R. Herling

Patent number: 8696771Abstract: A compact integrated combustion reactor is described. In a preferred embodiment, the combustion catalyst is disposed in a staggered configuration such that the hot spot in an adjacent endothermic reaction chamber is substantially less than would occur with a conventional, unstaggered configuration. The integrated reactor may also include a methanation chamber for methanation of a reformate product. Systems containing reactant and product streams, and methods of conducting integrated combustion reactions are also described. A staggered catalyst conformation can be used more broadly for thermal chemical reactions requiring heat transfer in a layered device.Type: GrantFiled: December 15, 2006Date of Patent: April 15, 2014Assignee: Battelle Memorial InstituteInventors: Daniel R. Palo, Jamelyn D. Holladay, Robert A. Dagle, Robert T. Rozmiarek
