Abstract

A gas separation process comprising feeding a gaseous mixture comprising at least two components having different adsorption characteristics into an adsorption vessel containing at least one adsorbent material capable of preferentially adsorbing at least one of the gaseous components in the gaseous mixture and subjecting the gaseous mixture to non-cryogenic conditions which enable the preferentially adsorbable gaseous component in the gaseous mixture to adsorb onto the adsorbent material and separate from the non-adsorbed component in the gaseous mixture which pass through the adsorbent vessel wherein at least one adsorbent material in the adsorbent vessel comprises a composite particle having an inner core comprising a non-porous, non-adsorbent material and at least one outer layer comprising the adsorbent material. In another embodiment of the process of the present invention a hollow particulate adsorbent material is utilized.
