Alkali-Promoted Activated Alumina Adsorbent

Abstract:

An adsorbent for removing CO.sub.2 from a gas mixture, the adsorbent comprising alumina and a carbonate compound where the carbonate to alumina IR absorbance intensity ratio is reduced by washing the adsorbent with water. The disclosure also describes a method of making adsorbent particles, process for removing CO.sub.2 from a gas mixture using the adsorbent, and an adsorption unit using the adsorbent.
