Abstract
An adsorbent for removing COfrom 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 COfrom a gas mixture using the adsorbent, and an adsorption unit using the adsorbent.
