(411d) Carbon Dioxide Capture with Hybrid Nanocomposites Conference: AIChE Annual MeetingYear: 2009Proceeding: 2009 AIChE Annual MeetingGroup: Catalysis and Reaction Engineering DivisionSession: Green Chemistry and Reaction Engineering II Time: Wednesday, November 11, 2009 - 1:30pm-1:50pm Authors: Qi, G., Cornell University Giannelis, E. P., Cornell University Park, A. H. A., Columbia University An amine functionalized silica nanocomposite was synthesized by a one-pot reaction in the presence of surfactant templates. Carbon dioxide adsorption from a simulated flue gas stream and pure dried CO2 under atmospheric pressure was successfully performed with the hybrid nanocomposite. The captured CO2 can be easily and completely recovered by a purge gas or heating to 50-100 °C. The multi-cycle experiments have shown that the adsorbent has very good stability and regenerability. A high organic loading, up to ~45 wt %, was achieved by the covalently bonding the organic groups to the silica support instead of physical impregnation, and as a result, a large CO2 absorption capacity ( 100mg CO2/g adsorbent) was observed for the absorbent. Results of analytical characterization of the hybrid nanocomposite will also be discussed.
