Carbon dioxide capture and concentration from combustion flue gases by adsorption based technology

Removal of CO2 from different gas streams, such as fossil fuel combustion gases, is becoming increasingly important to reduce effects of global warming. It is widely recognized that adsorption process is a promising technology provided that materials with high capacity and selectivity toward CO2 are available. Materials with sponge-like properties, such as ordered mesoporous silicas, are ideal for CO2 capture. If this type of material can be made highly efficient, reusable and stable, it will open the path to a low cost carbon sequestration. The performance of this material depends on a number of factors including aging time, temperature of synthesis and addition of specific functional groups to enhance the adsorption properties. A range of samples will be prepared under different synthesis conditions and tested under simulated real process conditions. We expect that the new material could provide a feasible solution to meeting CO2 emission restriction for industry. Since the CO2 adsorption/desorption process will be highly selective and reversible, the captured CO2 could be safely transported and stored, or be released and used for other purposes.
