  • Publication number: 20140311917
    Abstract: A method is disclosed for producing high purity, high pressure hydrogen from a low pressure synthesis gas production process. The low pressure synthesis gas is produced from steam or carbon dioxide reforming of hydrocarbons, autothermal reforming of hydrocarbons or partial oxidation of hydrocarbons. The resulting low pressure synthesis gas mixture is fed to an electro-chemical cell wherein hydrogen is separated from the low pressure synthesis gas mixture and subjected to compression and high pressure; high purity hydrogen is recovered from the electro-chemical cell.

  • Patent number: 8795481
    Abstract: A power generation system including an electrolyzer may be optimized taking non-linear operational constraints into account with lower processing requirements than current solutions in real time. A pre-processing module assesses non-linear operational constraints in a low-overhead manner and passes results to an optimization module. The optimization module determines an operating power value constrained in accordance with results from the pre-processing module. A post-processing module uses results from the pre-processing and optimization modules to assemble instructions to control the electrolyzer. As a result, optimization may be performed in real time.

  • Patent number: 8784619
    Abstract: A portable, on-demand hydrogen generation system is provided for producing hydrogen and injecting the hydrogen as a fuel supplement into the air intake of internal combustion engines, more particularly to vehicles. Hydrogen and oxygen is produced with a fuel cell at low temperatures and pressure from water in a supply tank. The hydrogen and oxygen is passed back thru the supply tank for distribution and water preservation. The gases are kept separate by a divider in the tank and the water level in the tank. In the case of gasoline engines, the hydrogen is directed to the air intake of the engine while the oxygen is vented to the atmosphere. The device is optionally powered by the vehicle battery, a stand alone battery, waste heat of the internal combustion engine or solar energy. The system utilizes a vacuum switch or other engine sensor that permits power to the device and therefore hydrogen production only when the engine is in operation.

  • Publication number: 20140183053
    Abstract: A method that produces coupled radical products. The method involves obtaining a sodium salt of a sulfonic acid (R—SO3—Na). The alkali metal salt is then used in an anolyte as part of an electrolytic cell. The electrolytic cell may include an alkali ion conducting membrane (such as a NaSICON membrane). When the cell is operated, the alkali metal salt of the sulfonic acid desulfoxylates and forms radicals. Such radicals are then bonded to other radicals, thereby producing a coupled radical product such as a hydrocarbon. The produced hydrocarbon may be, for example, saturated, unsaturated, branched, or unbranched, depending upon the starting material.
