Title: Catalyst functionalized buffer sorbent pebbles for rapid separation of carbon dioxide from gas mixtures

Patent ·
OSTI ID:1083061

A method for separating CO.sub.2 from gas mixtures uses a slurried media impregnated with buffer compounds and coating the solid media with a catalyst or enzyme that promotes the transformation of CO.sub.2 to carbonic acid. Buffer sorbent pebbles with a catalyst or enzyme coating are provided for rapid separation of CO.sub.2 from gas mixtures.
