Study of CO2 Capture Using Triethanolamine-Modified Mesoporous Silica


Article Preview

Novel functionalised absorbents have been synthesized by immobilization of triethanolamine on synthetic mesoporous silica for CO2 capture. Mesoporous silica material with a uniform pore size of 20-50nm and a surface area of 200~300 m2/g was used as loader for capturing agents. The capture of carbon dioxide from simulated flue gas streams has been achieved by using triethanolamine immobilized mesoporous silica. Preliminary attempts have also been made to determine the CO2 adsorption capacities of these newly developed materials. The results revealed that maximum adsorption capacities was 28.01mg/g for immobilized triethanolamine mesoporous silica at room temperature,and the rate of desorption is 99% at 90°C.Recycle of adsorption-desorption have many times,and the ability of capturing CO2 was stable. The results suggest that immobilized triethanolamine have a good affinity for the capture of carbon dioxide from simulated flue gas streams.The performance of these immobilized and triethanolamine-mesoporous silica solid sorbents decreased with regeneration.
