Abstract

A process for separating a gas component from a gas mixture is disclosed. A gas mixture is passed through an adsorption zone which contains an adsorbent which will selectively adsorb a gaseous component from the gas mixture. The adsorption zone contains a layer of monolithic adsorbent and a layer of adsorption beads. Optionally, a third monolithic layer may be employed. The adsorption zone is typically contained in an adsorption vessel.
