Abstract
Process for treating an alcohol composition containing nitrogen-containing contaminants by contacting the alcohol composition with an adsorbent in an adsorption zone. The adsorbent is a transition metal-loaded solid porous material selected from aluminosilicates, silica-aluminas, silicates and aluminas, and the alcohol composition is contacted with the adsorbent either alone or in the presence of an inert carrier gas.
