Publication number: 20140301941Abstract: A process for extracting hydrocarbons from a molecular combination is provided. The process includes heating a molecular combination to dissociate it into a particle stream of carbon cations, hydrogen cations, and oxygen anions; guiding the stream through a non-conductive conduit; moving the dissociated particle stream through a magnetic field to separate the cations from the anions; and isolating the separated cations from the anions. In one embodiment, methane is formed from carbonic acid.Type: ApplicationFiled: June 23, 2014Publication date: October 9, 2014Inventor: Timothy O. Nichols

Patent number: 8852822Abstract: When terminating power generation by a fuel cell 3 in a fuel cell system 1, an amount of a raw fuel material introduced to a reforming catalyst 2a of a reformer 2 is reduced. Here, before the temperature of the reforming catalyst 2a is lowered to the un-reformed gas generation temperature, an amount of water supplied to the reforming catalyst 2a is controlled to increase the temperature of the reforming catalyst 2a. Thus, upon termination of power generation in the fuel cell 3, no un-reformed gas is generated and the reformed gas is supplied to the fuel cell 3.Type: GrantFiled: January 8, 2014Date of Patent: October 7, 2014Assignee: Nippon Oil CorporationInventor: Tomotaka Ishida

Publication number: 20140287333Abstract: Methods are disclosed for generating electrical power from a compound comprising carbon, oxygen, and hydrogen. Water is combined with the compound to produce a wet form of the compound. The wet form of the compound is transferred into a reaction processing chamber. The wet form of the compound is heated within the reaction chamber such that elements of the compound dissociate and react, with one reaction product comprising hydrogen gas. The hydrogen gas is processed to generate electrical power.Type: ApplicationFiled: February 19, 2014Publication date: September 25, 2014Applicant: Proton Power, Inc.Inventors: Samuel C.

Patent number: 8840692Abstract: Techniques, systems and material are disclosed for transport of energy and/or materials. In one aspect a method includes generating gaseous fuel (e.g., from biomass dissociation) at a first location of a low elevation. The gaseous fuel can be self transported in a pipeline to a second location at a higher elevation than the first location by traveling from the first location to the second location without adding energy of pressure. A liquid fuel can be generated at the second location of higher elevation by reacting the gaseous fuel with at least one of a carbon donor, a nitrogen donor, and an oxygen donor harvested from industrial waste. The liquid fuel can be delivered to a third location of a lower elevation than the second location while providing pressure or kinetic energy.Type: GrantFiled: August 13, 2012Date of Patent: September 23, 2014Assignee: McAlister Technologies, LLCInventor: Roy Edward McAlister

Publication number: 20140261132Abstract: Systems and methods for storing energy in gaseous form in submerged thin-walled tanks are secured to the ocean or lake floor but are open to the water at the tank bottoms and are configured to be filled with gas while submerged. A conduit operatively connected to the tanks provides flow from a surface source of an energy-containing gas to the tank interiors. Surface or subsurface pumping apparatus which may include piston-less pressure cylinders or have leveraged pistons provide a preselected flow rate of the energy-containing gas into the containment structure interior against a back pressure essentially equal to the static pressure of the body of water at the location of the tank to displace an equivalent volume of water through the open bottom. The conduit can be configured to allow heat transfer to vaporize liquefied gas prior to storage. Hydrogen gas can be generated and stored within the tank using Aluminum activated with Galinstan.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Inventors: Fevzi Zeren, Zekeriye Konukoglu

Patent number: 8834585Abstract: A hydrogen generating device is adapted for a fuel cell. The hydrogen generating device includes a casing, a button, a solid reactant, a bag-shaped body, and at least one flexible element. The casing has a containing space and an opening. The button is integrally formed and connected to the casing to seal the opening. The solid reactant is disposed in the casing. The bag-shaped body is disposed in the casing and contains a liquid reactant. The flexible element is connected to the casing and is located in the containing space. The flexible element includes a bending end, wherein the flexible element is aligned to the button and is located between the button and the bag-shaped body. When the button is pressed, the button pushes the flexible element so the bending end pierces the bag-shaped body, and the liquid reactant flows out and reacts with the solid reactant to generate hydrogen.Type: GrantFiled: July 21, 2011Date of Patent: September 16, 2014Assignee: Young Green Energy Co.Inventors: Yu-Hsiang Lin, Hsuan-Yi Lu

Patent number: 8834604Abstract: A membrane for use in a high temperature gas processing system and method for making the same. The membrane includes a dense, gas impermeable layer and a first and second porous layer, wherein each of the first and second porous layers is a ceramic oxide material having a non-symmetrical load bearing skeleton of a plurality of pores having a graded porosity. Each porous layer provides a reduction of an oxygen partial pressure gradient across the dense layer and reduces resultant stresses in the dense layer that are small compared to its strength thereby improving long term mechanical durability of the dense layer.Type: GrantFiled: September 16, 2011Date of Patent: September 16, 2014Assignee: Volt Research, LLCInventors: Ajit Y.
