Enhanced and functionalized carbon molecular sieve for simultaneous removal of CO2 and water from air

摘要

A carbon dioxide and water adsorbent comprises a carbonized and activated precursor material having first functional sites that adsorb carbon dioxide and second functional sites that adsorb water independently of the first functional sites. The adsorbent is characterized by a total pore volume of between about 1.50 to 2.50 cm3/g, a median pore diameter between about 0.5 to 1.2 nm, and a BET surface area between about 2000 to 2500 m2/g.
