  • Patent number: 12151216
    Abstract: A zeolite membrane composite includes a porous support and a zeolite membrane formed on the support. The zeolite membrane includes a low-density layer that covers the support, and a compact layer that covers the low-density layer. The compact layer has a higher content of a zeolite crystalline phase than the low-density layer. By in this way forming the compact layer on the low-density layer that covers the support, the thin compact layer with no defects can be formed more easily than in the case where a compact layer is formed directly on a support.

  • Patent number: 12145099
    Abstract: According to the method and device for a membrane-based processing of ambient water-group species, the species are captured in a space environment by an ionic liquid disposed on a presenting face of a semipermeable membrane. To seamlessly process the captured species for in-situ resource utilization without need of moving parts, they are urged to pass through the membrane by a predetermined electric potential difference applied between opposite sides of the membrane via electrode contacts; an initial storage envelope is provided by an impermeable membrane attached to a back face of the semipermeable membrane. The device can be stowed in a manner of rolled plastic and deployed by unrolling. The device can also be configured as a scientific instrument to monitor a flux of ambient water-group species impinging in the space environment using electrical measurements.

  • Patent number: 12102957
    Abstract: A device for reducing a carbon dioxide and water content in an enclosed air volume has first and second sorption units for sorbing carbon dioxide and water. The first and second sorption units can be transferred from a sorption mode into a desorption mode and vice versa. In the sorption mode, the first and second sorption units sorb carbon dioxide and water from raw air of the enclosed air volume. In the desorption mode, the first and second desorption units desorb carbon dioxide and water to supplied regeneration air. An air distribution device can switch the first and second sorption units, based on the carbon dioxide and water content, alternately from sorption mode into desorption mode such that, in at least one operating state of the device, one of the first and second sorption units is in sorption mode while the other is in desorption mode.
