Abstract:

Processes, methods, systems and devices for zero emission liquid hydrogen production directly from a variety of methane sources, such as natural gas and landfill gas, are disclosed. Five embodiments of plant designs for liquid hydrogen production are presented. The embodiments combine hydrogen production and liquefaction into a single process to produce liquid hydrogen directly via methane containing gases; thus, eliminating the conventional technology of pressure swing adsorption process for gas mixture separation. The innovative process can be applied to produce high purity liquid hydrogen with no carbon dioxide emission to the atmosphere; and can also co-produce highly pure solid carbon and liquid carbon dioxide as by-products for industrial application. The invention has provided advantages over conventional approaches that result in up to approximately 85% of first low efficiencies and approximately 56% of second law efficiency, up to approximately 100% of hydrogen and methane recovery, and a very high purity of liquid hydrogen (99. 9999%).

Abstract:

A system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide. The sour gas mixture is reacted with a transition metal compound in a scrubber. Sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer including a power source. During the electrochemical redox reaction a voltage from the power source applied to the electrolyzer is controlled to regenerate the transition metal compound at a rate sufficient to match a flow rate of hydrogen sulfide into the scrubber or maintain a predetermined maximum hydrogen sulfide level out from the scrubber. The transition metal compound regenerated is returned to the scrubber for the reacting.

Abstract:

A novel M—Pd—CrO(M═Pt, Ru, Rh, Os, Au and Ag) nanocomposite cocatalysts and its preparation method. The cocatalysts loaded on CdS photocatalyst enhances the photocatalytic activities toward Hevolution from aqueous solutions (NH)SO, a regenerable electron donor, under sunlight radiation. An embodiment provides a new and facile method and system for the preparation of M—Pd—CrOnanocomposite cocatalysts at room temperature. Pd—CrOloaded CdS photocatalyst has higher hydrogen evolution activity than that of a plain Pd metal loaded CdS and its performance is comparable to that of Pt/CdS photocatalyst. Formation of a Pd—CrOcomposite with reduced size of nanoparticles results in an increase in the photocatalyst activity for Hevolution.

Abstract:

A method for the production of hydrogen via thermochemical water splitting includes the steps of providing an ammonium sulfite compound, dissolving the ammonium sulfite in water, and oxidizing the aqueous ammonium sulfite solution, wherein hydrogen is produced as a water reduction product associated with the oxidation. If purified air is used instead for the oxidation of aqueous ammonium sulfite solution, the method produces oxygen from the purified air. In a preferred embodiment of the invention, the oxidation is a photooxidation. Light for the photoxidation can be provide by a direct light source, such as solar energy, or indirectly from conversion of electrical energy to light, such as using a UV or visible light lamp. Electrical energy can be provided by a variety of sources, including low cost sources comprising wind driven, water driven (hydroelectric), or nuclear power.

US Classification:

481277, 481279

Abstract:

A method and system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide includes providing an aqueous solution comprising a transition metal oxide, sulfide or carbonate compound, wherein a transition metal of the transition metal oxide is at a first valence and has at least one reduction state from the first valence. The sour gas mixture is reacted with the transition metal compound and the aqueous solution in a reactor, wherein sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer comprising an anode, a cathode, and an electrolyte membrane between the anode and cathode, wherein an oxygen including gas is added to the cathode during the electrochemical redox reaction. The transition metal compound that is regenerated in the electrochemical redox reaction is then returned to the reactor for the reacting.

Abstract:

Methods and systems for separating hydrogen and sulfur from hydrogen sulfide(HS) gas. Hydrogen sulfide(HS) gas is passed into a scrubber and filtration unit with polysulfide solution. Interaction frees elemental sulfur which is filtered, excess continues to a stripper unit where the excess HS is removed. The excess HS returns to the scrubber and filtration unit, while the sulfide solution passes into a photoreactor containing a photocatalyst and a light source. The sulfide solution is oxidatively converted to elemental sulfur and complexed with excess sulfide ion to make polysulfide ion, while water is reduced to hydrogen. Hydrogen is released, while the polysulfide solution is fed back to the scrubber unit where the system operation repeats. In a second embodiment, the photocatalyst is eliminated, and the hydrogen sulfide solution is directly illuminated with ultraviolet radiation with a light source such as a low pressure mercury lamp operating at approximately 254 nm.

Abstract:

This invention relates to a new process to directly produce transportation gasoline from synthesis gas containing principally carbon monoxide, carbon dioxide, and hydrogen, The process entails three sequential catalytic stages with intermediate heat exchange to provide the requisite temperature in each stage, but with no interstage separation. The recycle loop enhances the conversion of the synthesis gas to the desired products and also serves as heat sink for the highly exothermic reactions involved in each stage.
