Improvements related to sorbent media

Abstract

A sorbent pellet comprising a sorbent material. The sorbent pellet is suitable for use in a sorbent rotor device, for example to capture water or water vapour from a gaseous or liquid composition comprising water or water vapour. The sorbent material has a unit cell density of at least 0.8 g/cm3 and may therefore be considered to be a high density sorbent material. A plurality of sorbent pellets may provide a high capacity media for a sorbent rotor device, which may be particularly effective in dehumidification, desalination or water purification processes. Also disclosed are a cartridge for a sorbent rotor device, a sorbent rotor device for capturing water from a liquid or gaseous composition comprising water, a method of capturing water from a composition comprising water and/or water vapour, and a use of a sorbent material having a density of at least 0.8 g/cm3 in pellet form to capture water from air.
