  • Patent number: 11583824
    Abstract: A system and method for producing hydrogen from hydrocarbon and steam, including a membrane reformer with multiple membrane reactors each having a tubular membrane. The bore of the tubular membrane is the permeate side for the hydrogen. The region external to the tubular membrane is the retentate side for carbon dioxide. A sweep gas flows through the bore to displace hydrogen in a direction countercurrent to flow of hydrocarbon and steam in the region external to the tubular membrane. The method includes discharging hydrogen as permeate with the sweep gas from the bore, and discharging carbon dioxide in the region external to the tubular membrane as retentate from the membrane reactor.

  • Patent number: 11453827
    Abstract: A syngas generator is disclosed as an exothermic gas generator that can accommodate high combustion temperatures of a natural gas/oxygen flame. The generator includes four sections: a heavily insulated combustion chamber, a catalyst chamber, a spray chamber, and a heat exchanger. These four sections may be arranged in series and tightly bolted together to form a gas-tight system. Natural gas, oxygen and steam are supplied to a burner at the inlet end of the combustion chamber. This mixture is ignited and the resulting hot process gas is then fed into a catalyst bed where it reacts with the steam and is converted to carbon monoxide and hydrogen (syngas). The syngas is fed to a Fischer-Tropsch unit to create liquid fuel.

  • Publication number: 20150110708
    Abstract: Process for producing a hydrogen-containing product and one or more liquid water products using catalytic steam-hydrocarbon reforming. In the process, a portion of the make-up water is heated by the reformate and another portion of the make-up water is heated by the combustion product gas prior to introducing the make-up water to a deaerator. Water in the combustion product gas is condensed to form a liquid water product. The process may be integrated with a thermal water desalination process.

  • Patent number: 9011814
    Abstract: 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.

  • Patent number: 8979953
    Abstract: An apparatus for generating hydrogen including a housing, a reservoir, and a piston is provided. The housing has a top wall, a bottom wall, and a sidewall. The top wall has vents and a protrudent column extending to the interior of the housing. At least one vent communicates with the top wall and the protrudent column and rest of the vents surround the protrudent column. The reservoir is disposed in the housing for storing a solid state reactant and divides the housing into a first chamber and a second chamber. The first chamber is located between the top wall and the reservoir. The second chamber is located between the bottom wall and the reservoir for storing a liquid reactant. The piston is disposed on the bottom wall. The piston is used to push the liquid reactant towards the reservoir to react with the solid state reactant to generate hydrogen.

  • Patent number: 8961829
    Abstract: The invention relates to a process of making a syngas mixture containing hydrogen, carbon monoxide and carbon dioxide, comprising a step of contacting a gaseous feed mixture containing carbon dioxide and hydrogen with a catalyst, which catalyst substantially consists of Mn oxide and an oxide of at least one member selected from the group consisting of Cr, Ni, La, Ce, W, and Pt. This process enables hydrogenation of carbon dioxide into carbon monoxide with high selectivity, and good catalyst stability over time and under variations in processing conditions. The process can be applied separately, but can also be integrated with other processes, both up-stream and/or down-stream; like methane reforming or other synthesis processes for making products like alkanes, aldehydes, or alcohols.

  • Patent number: 8951312
    Abstract: A compact, chemical-mechanical apparatus, having no electrical components, for storing and generating hydrogen safely, on-demand, at the time and point of use in small or large quantities using the environmentally clean chemical reaction between sodium metal and water to generate hydrogen (H2) gas and sodium hydroxide (NaOH) byproduct is presented, for powering electricity generating fuel cells for large scale commercial and private electric motor vehicle transport. The apparatus of the present invention supports hydrogen gas generation by the controlled addition of liquid water to solid sodium metal to produce hydrogen gas and sodium hydroxide using only mechanical components without electrical components that require external power and can generate sparks or short circuits, producing catastrophic failure in hydrogen systems.

  • Patent number: 8940061
    Abstract: An apparatus for generating hydrogen for fuel cells is provided. The apparatus includes a housing, a button, a first separating plate, a solid state reactant, and a separating membrane. The housing has an opening and a reservoir. The button connected to the housing covers the opening. The first separating plate disposed in the housing divides the reservoir into first and second sub-rooms. The opening communicates with the first sub-room and the first sub-room is suitable for storing a liquid reactant. The first separating plate has a through hole opposite to the button. The solid state reactant is disposed in the second sub-room. The separating membrane disposed on the through hole separates the first sub-room from the second sub-room. When the button is pushed, the button damages the separating membrane. Therefore, the liquid reactant flows to the second sub-room and reacts with the solid state reactant to generate hydrogen.
