COMPOSITE ADSORBENT BEAD, PROCESS FOR ITS PRODUCTION, GAS SEPARATION PROCESS AND GAS ADSORPTION BED

摘要

Composite adsorbent beads have a porous and non- adsorbent core comprising at least one inorganic material and a porous and adsorbent shell comprising at least one adsorbent layer comprising a porous adsorbent material on the surface of the core. The core preferably comprises agglomerated inorganic particles having a mean particle size equal to or smaller than the mean particle size of the surrounding agglomerated adsorbent particles. The beads preferably are manufactured by calcining together a non- sintered core and the adsorbent layer. The beads can be used at the outlet end of an adsorption column to improve performance.
