Abstract

In this study, the effects of two materials, active alumina and CaO based inorganic binder, which cause the side reaction on the K2CO3-based solid CO2 sorbents was investigated. K2CO3-based solid sorbents called KAM series was prepared by spray drying method and then measured its physical properties and CO2 sorption capacity. Among the KAM series sorbents, KAM(0.5) maintained high CO2 sorption capacity of 7.6 wt% after 3 cycle of sorption/regeneration reaction and showed very low attrition loss as low as 3.1 % which was measured by ASTM D5757-95.
