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.

Adsorbent cartridge with accurate visual indicator

Provided herein are a parallel passage contractors, which may be useful in pressure swing adsorption (PSA), pressure and temperature swing adsorption (PTSA), or vacuum pressure swing adsorption (VPSA) systems, having one or more self-supported adsorbent sheets arranged in multiple, overlapping layers mechanically spaced to allow gas flow. Also provided are systems utilizing such parallel passage contactors and methods for preparing the contactors.

Durable adsorbent material and adsorbent packs and method of making same

This invention relates to an adsorbent cartridge assembly having at least one end cap, and systems related thereto, for removing gaseous contaminants from the air or other gases.

Adsorbent cartridge assembly with end cap

This invention relates to an adsorbent system, adsorbent cartridge, and external canister for removing gaseous contaminants from air or another gas.

Adsorbent system for removal of gaseous contaminants

An adsorbent is described. The adsorbent may include a membrane and an adsorbent material encapsulated within the membrane. An inhalation device is also described. The inhalation device may include a housing and a membrane within the housing. The membrane may encapsulate an adsorbent material. The membrane may be positioned such that airflow through the housing passes across but not through the membrane.

Adsorbents and inhalation devices

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.

Method of manufacturing and using enhanced carbon dioxide adsorbent

A CO2 removal system including a member having a first opening and a second opening to enable air flow containing carbon dioxide (CO2) to pass from the first opening to the second opening and lithium hydroxide (LiOH) supported by the member and having an initial water content above an anhydrous level. In one embodiment, LiOH adsorbent density is a maximum of approximately 1.0 g/cm.
