  • Patent number: 12643790
    Abstract: A hydrocarbon stream is combusted within a reactor to produce soot and syngas. Sub-stoichiometric combustion of the hydrocarbon stream within the reactor converts at least 10% of the carbon in the hydrocarbon stream into soot. The syngas is mixed with a steam stream to produce a hydrogenation feed stream. A shift reactor converts at least a portion of the carbon monoxide and steam to carbon dioxide and hydrogen to produce a shifted gas stream. Water is separated from the shifted gas stream to produce a dehydrated gas stream. The dehydrated gas stream is separated to produce a hydrogen product stream and a recycle stream. The recycle stream is recycled to the reactor.

  • Patent number: 12606435
    Abstract: A method of generating oxygen includes introducing a hydrogen peroxide solution (at least 39.5%) into a reactor that has a passage, an oxygen outlet at one end of the passage, a water outlet at another end of the passage, and an inlet between the ends of the passage. Silver flakes are packed tightly within the passage forming interstices to accommodate fluid flow in a substantially restricted manner such that substantial fluid flow only occurs under influence of a pressure differential in the passage that exceeds a predetermined threshold value associated with the fluid. The silver flakes catalyze a decomposition reaction of the hydrogen peroxide into water and oxygen. The hydrogen peroxide and the decomposition reaction move in a stepwise, periodic manner through the interstices from the inlet toward the water outlet. The oxygen and water vapor flow toward the oxygen outlet.

  • Patent number: 12582967
    Abstract: The present invention is directed to both stoichiometric and sub-stoichiometric high entropy aluminate spinels as a novel high entropy oxide (HEO) crystal phase. Previously reported HEOs are overwhelmingly stoichiometric structures containing a single cationic site and are stabilized solely by intermixing increasing numbers of cations. According to an aspect of the invention, sub-stoichiometric spinels, containing various mixtures of divalent metal cations and cationic vacancies in nominally equimolar concentration, provide entropic stabilization similarly to cations in stoichiometric spinels. The chromatic, structural, and chemical properties of these complex spinels are highly tunable via incorporation of cationic vacancies and multiple divalent metals, enabling their application as unique pigments, catalysts, and thermal coatings.
