Abstract
An adsorption system having at least one adsorber retaining a bed of adsorbent material can be configured to provide enhanced purification of fees having relatively low concentrations of hydrogen or helium. Embodiments can utilize an activated carbon layer between at least one upstream layer and at least one downstream layer. The activate carbon layer can include activated carbon can have a pre-selected surface area (SA), bulk density, total open pore volume (TOPV), and/or ratio of TOPV to surface area (TOPV/SA).
Claims12
An adsorber for an adsorption system comprising:
- a vessel positionable to receive a fluid to purify the fluid, the vessel having a bed of adsorbent material;
- the bed of adsorbent material comprising an activated carbon layer including activated carbon, the activated carbon of the activated carbon layer having:
- (i) a surface area (SA) that ranges from 380 m2/g to 750 m2/g;
- and
- (ii) a total open pore volume (TOPV) to SA ratio (TOPV/SA), which has a value greater than 0.59 nm and less than 0.83 nm.
