Patent number: 11925763Abstract: A cartridge comprising layers of adsorbent sheet is described. The cartridge includes an indicator that characterizes the consumption state of the adsorbent within the cartridge. The indicator is applied in a way such that discrete areas of indicator are visible. These discontinuous areas of indicator may be applied to the outside surface of the cartridge. Alternatively, the discontinuous areas may be formed by cutting windows in the outermost layer of the cartridge and either coating indicator on the layer beneath the window, placing an indicator layer between the window and the layer beneath it or filling the window with an indicating plug of material so that the indicator is visible from the outside of the cartridge. The indicator layer and indicator plug embodiments allow the use of any indicator with any adsorbent.Type: GrantFiled: November 29, 2022Date of Patent: March 12, 2024Assignee: Micropore, Inc.Inventors: Douglas B. McKenna, Vince Suddard, Glenn Shealy

Patent number: 7329307Abstract: A method of processing carbon dioxide adsorbent for use in a CO2 removal system. The method includes combining a polymer, lithium hydroxide (LiOH), and lubricant that dissolves the polymer to form a first LiOH adsorbent. A structure may be formed using the first LiOH adsorbent. The lubricant may be extracted from the structured LiOH adsorbent using a solvent to form a second LiOH adsorbent. The solvent may be removed from the second LiOH adsorbent to form a third LiOH adsorbent. The third LiOH adsorbent may be hydrated to form a fourth LiOH adsorbent having a water content above an anhydrous level.Type: GrantFiled: January 28, 2005Date of Patent: February 12, 2008Assignee: Micropore, Inc.Inventors: Michael B.
