Abstract

An improved method for preparing and activating monolith adsorbents is disclosed. A regeneration gas is passed through the formed monolith adsorbent at a temperature sufficient to decompose at least part of the binding agents in the adsorbent. The present invention also provides for the use of the treated adsorbent monoliths in separating gases in cyclical separation processes such as vacuum swing adsorption processes.
