Continuous CO2 Capture in Dual Fluidized Beds Using Silica Supported Amine
2013
Energy Procedia
In this study, a supported amine sorbent was prepared by impregnating silica particles (150~300 um) with methanol solution of polyethylenimine (PEI with the molecular weight of 600 g· mol -1 ) to immobilize amine into the pores of the silica support. The optimal CO 2 capacity of the PEI-based sorbent was as high as 2.0 mmol· g -1 . During the adsorption and desorption of 10 times, the CO 2 capacity of the PEI-based sorbents kept stable, indicating PEI-based sorbents had excellent thermal
