Solicitante:

SMITH MICHAEL J [US]

Resumen de: WO2022169727A1

The present application discloses a uniquely-sited electrolysis plant for converting water to molecular hydrogen and molecular oxygen. The electrolysis plant is powered by a renewable-energy generator. In the preferred embodiment, the renewable-energy generator is a solar-cell array, preferably perovskite-enhanced solar panels, and is located in or on a non-navigable body of water or a non-navigable portion of a body of water. The electrolysis plant supplies hydrogen to a nearby transportation refueling station and/or to a nearby industrial or commercial facility. In an embodiment of the invention, the renewable-energy generator is a wind turbine used instead of solar power to power the electrolysis plant.

Resumen de: US2022251720A1

Electrolytic cells for electrolysis of water, the electrolytic cells including two sub-cells, one containing the anode, the other the cathode. The electrolytic cells are configured so that at least the hydrogen formed due to electrolysis is passed through a deflection tube and into an electrolyte outside of the electrolytic sub-cell. This configuration serves as a security measure to prevent a flashback of a combustion reaction, and makes the presence of a separate bubbler superfluous.

Efficent 2-step process for the direct production of liquid fuels from carbon dioxide and hydrogen

NºPublicación: US2022251455A1 11/08/2022

Solicitante:

INFINIUM TECH LLC [US]

WO_2022169536_A1

Resumen de: US2022251455A1

Embodiments of the present invention relate to two improved catalysts and associated processes that directly convert carbon dioxide and hydrogen to liquid fuels. A catalytic system comprises two catalysts in series that are operated in tandem to directly produce synthetic liquid fuels. The carbon conversion efficiency for CO2 to liquid fuels is greater than 45%. The fuel is distilled into a premium diesel fuels (approximately 70 volume %) and naphtha (approximately 30 volume %) which are used directly as “drop-in” fuels without requiring any further processing. Any light hydrocarbons that are present with the carbon dioxide are also converted directly to fuels. This process is directly applicable to the conversion of CO2 collected from ethanol plants, cement plants, power plants, biogas, carbon dioxide/hydrocarbon mixtures from secondary oil recovery, and other carbon dioxide/hydrocarbon streams. The catalyst system is durable, efficient and maintains a relatively constant level of fuel productivity over long periods of time without requiring re-activation or replacement.

SCHERRER INST PAUL [CH]

CN_114080475_PA

Resumen de: US2022251721A1

A method of preparing an ionomer of an ion exchange membrane with a recombination catalyst to prevent gas crossover of species, such as hydrogen and/or oxygen, to anodic and cathodic cell compartments of an electrochemical cell. An ionomer of an ion exchange membrane is prepared with a recombination catalyst. The ionomer is a proton or anion exchange polymer and the recombination catalyst, selected from the precious metals group, is provided in ionic form in a liquid metal salt solution. The ion exchange membrane is immersed into the liquid metal salt solution to exchange ionic ionomer ports with the ionic form of the recombination catalyst. The membrane is then assembled in the electrochemical cell and the ionic form of the recombination catalyst is at least partly reduced to metallic form by forcing hydrogen to permeate through the ionomer of the ion exchange membrane.

NºPublicación: WO2022167880A1 11/08/2022

Solicitante:

CTS H2 S R L [IT]

Resumen de: WO2022167880A1

The present invention is relative to a separator/electrodes assembly to be positioned within an appropriate electrolytic cell for the production of hydrogen at high pressure, alternative to the classic MEA, provided with a particularly compact and sturdy structure that makes it possible to achieve an excellent efficiency of the system. In practice, the structure is designed to reduce, or even eliminate the so-called "crossover" of oxygen into the hydrogen and vice-versa, so as to allow the increase in pressure directly in the cell, without compressors, and to facilitate its production and the maintenance operations, thanks to the fact that the apparatus consists of a single metallic piece (One Piece Core, "OPC"). This apparatus is used in the scope of the "AES" (Solid State Alkaline) technology, which shares the principles of the alkaline polymeric membrane (AEM) technology, without resorting to the use of polymeric membrane.
