The method comprises forcing a liquefied alkali metal through a filter that separates the liquid alkali metal into alkali metal droplets. The alkali metal droplets comprise small enough particles that the alkali metal droplets completely react in water to produce heat, steam, an alkaline hydroxide and hydrogen gas before the alkali metal droplets reach the surface of the water. The filter separates the alkali metal droplets at a sufficient distance to avoid recombining of the alkali metal droplets. The alkaline hydroxide is reduced to an alkali metal and water which can be reused in the system.Type: GrantFiled: June 13, 2011Date of Patent: June 11, 2013Inventor: Bruce McGill

Patent number: 8420032Abstract: Reactors and methods for solar thermochemical reactions are disclosed. Embodiments of reactors include at least two distinct reactor chambers between which there is at least a pressure differential. In embodiments, reactive particles are exchanged between chambers during a reaction cycle to thermally reduce the particles at first conditions and oxidize the particles at second conditions to produce chemical work from heat. In embodiments, chambers of a reactor are coupled to a heat exchanger to pre-heat the reactive particles prior to direct exposure to thermal energy with heat transferred from reduced reactive particles as the particles are oppositely conveyed between the thermal reduction chamber and the fuel production chamber. In an embodiment, particle conveyance is in part provided by an elevator which may further function as a heat exchanger.Type: GrantFiled: August 29, 2011Date of Patent: April 16, 2013Assignee: Sandia CorporationInventor: Ivan Ermanoski

Patent number: 8418435Abstract: Aluminum is treated with an agent to prevent passivation of the aluminum during oxidation. The passivation preventing agent is a metal alloy containing gallium, preferably a eutectic alloy of gallium, indium and tin. The surface of the metallic aluminum is wetted with the eutectic alloy, suitably by scouring and/or immersion. The treated aluminum may be mixed with water, hydrogen peroxide or other suitable oxidizer in a controlled manner to produce hydrogen, heat, steam or oxygen for the use in power generation or chemical reactions. The passivation removal agent can be used in small quantities and is readily recoverable following the reaction.Type: GrantFiled: June 12, 2009Date of Patent: April 16, 2013Inventor: Nagi Hatoum

Patent number: 8383078Abstract: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.Type: GrantFiled: February 11, 2010Date of Patent: February 26, 2013Assignee: GTLpetrol LLCInventors: Shoou-I Wang, John Michael Repasky, Shankar Nataraj, Xiang-Dong Peng
