  • Patent number: 11642634
    Abstract: The description relates to methods and apparatus that enable the efficient introduction of gases like air, oxygen and ozone into aqueous liquids. Gases are introduced into liquids for making that gas chemically or biologically available at a minimum energy expenditure. Impinging jets of liquid are directed into a pressurized saturation vessel having a gas-filled headspace and a saturation zone below the surface of the liquid at a velocity sufficient to create a turbulent impact and plunge zone. The resulting turbulence and mixing of gas and liquid in that zone under pressure, causes the gas to be driven into the liquid in the vessel and breaks up the gas and the liquid into a churning flow and creates a large number of bubbles. The resulting gas-enriched liquid is discharged from the vessel at an outlet to ensure a minimum of bubbles in the gas-enriched liquid.

  • Patent number: 11642667
    Abstract: The present disclosure relates to a multi-sandwich composite catalyst and a preparation method and application thereof. The present disclosure provides a preparation method of a multi-sandwich composite catalyst, comprises the following steps: sequentially depositing a first layer oxide, a first active metal, an oxide interlayer, a second active metal and a surface oxide on a template, and sequentially performing calcination and reduction, thereby obtaining a multi-sandwich composite catalyst; wherein the first active metal and the second active metal are different kinds of active metals. In the present disclosure, a multi-sandwich structure is formed by depositing the oxides and active metals alternately, so that the position and spacing distance of the active centers can be precisely controlled. The multi-sandwich composite catalyst prepared by the method provided described herein has a higher conversion than that of a catalyst without an interlayer when used for the catalytic reaction.

  • Patent number: 11642673
    Abstract: A flow cell having at least one storage zone connected to a duct for conducting fluid out of, into or/and through the storage zone. The duct includes a duct section which is delimited by a substrate and a film joined to the substrate and in which the duct is sealed and can be opened at a predetermined breaking point by deflecting the film. The film covers a recess in the substrate which forms the duct section. A sealing wall that seals the duct and is integrally joined to the substrate is placed in the recess. The predetermined breaking point is formed by a breakable joining region between the film and an edge portion of the sealing wall facing the film. The dimensions of a peripheral area of the sealing wall which is formed in the edge portion and runs parallel to the film determine the surface area of the joining region.
