Patent number: 8821824Abstract: A process for removal of tritium from materials that are contaminated thereby envisages the use of a detritiation reactor RT, in which the reaction for the removal of tritium from the waste takes place, the waste being recovered by a flow of moist inert gas in which an extremely low percentage of humidity is used.

Patent number: 8728180Abstract: A reformer is disclosed in one embodiment of the invention as including a channel to convey a preheated plurality of reactants containing both a feedstock fuel and an oxidant. A plasma generator is provided to apply an electrical potential to the reactants sufficient to ionize one or more of the reactants. These ionized reactants are then conveyed to a reaction zone where they are chemically transformed into synthesis gas containing a mixture of hydrogen and carbon monoxide. A heat transfer mechanism is used to transfer heat from an external heat source to the reformer to provide the heat of reformation.Type: GrantFiled: May 8, 2007Date of Patent: May 20, 2014Assignee: Ceramatec, Inc.Inventors: Joseph J. Hartvigsen, Singaravelu Elangovan, Piotr Czernichowski, Michele Hollist, Michael Boettcher

Publication number: 20140134100Abstract: The current disclosure is directed to a hydrogen-storage system that employs catalytic dehydrogenation of low-molecular-weight amines in a hydrogen reactor. The hydrogen-storage system comprises aliphatic amines and di-amines as organic carriers that store hydrogen covalently, a hydrogen reactor that releases and separates hydrogen gas from the carrier, and metal or metal-oxide catalysts that promote a dehydrogenation reaction to release hydrogen. In certain implementations, a metal or metal-oxide catalyst may be carried on high-surface-area support materials, such as gamma-alumina and metal-organic-framework materials, to enhance catalytic properties. The hydrogen reactor may be a packed-bed reactor, a monolith reactor, or a flow-through hydrogen-membrane reactor.Type: ApplicationFiled: January 16, 2014Publication date: May 15, 2014Applicant: ASEMBON INC.Inventors: Esmaeel Naeemi, David G.

Publication number: 20140134099Abstract: A process is described for flowing an oxygenate feed over a catalyst in an adiabatic fixed bed reactor to product a reactor effluent and heat. The reaction inside the adiabatic fixed bed reactor occurs at a reaction temperature from about 200° C. to about 375° C. The reactor effluent is then condensed to separate the liquid products and the gaseous products. A separation step then separates the gaseous products into hydrogen and off-gas.Type: ApplicationFiled: November 11, 2013Publication date: May 15, 2014Applicant: Phillips 66 CompanyInventors: Uchenna P.
