Electrically regenerable mesoporous carbon for CO2 capture

High capacity carbon adsorbents, with high mesoporous volumes, high surface areas and narrow pore size distributions, were prepared in powdered form. These were prepared using a reverse replication method, in which sucrose is carbonized inside a mesoporous silica template. These carbon adsorbents were then functionalized using a multi-step synthesis to form amine functionalized products suitable for CO2 adsorption. The reversible CO2 adsorption capacities significantly improved upon functionalization. Functionalized carbon samples were also prepared in monolithic form, via a binderless pelletization procedure. These amine functionalized carbon monoliths had the potential to be used in an electrical swing adsorption procedure. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
