단신 : K2CO3를 담지시킨 고체 허니컴 이산화탄소 흡수제의 제조 및 이의 특성 평가 = Notes : Preparation of Honeycomb Carbon Dioxide Adsorbent Impregnated K2CO3 and Its Characterization

다국어 초록 (Multilingual Abstract)

To capture and recover carbon dioxide (CO2), we impregnated honeycomb made of ceramic paper with K2CO3 and its absorption characteristics of CO2 were investigated. The absorption amount of CO2 on the honeycomb absorbent impregnated with K2CO3 was 13.8 wt% at a constant temperature (70 ℃) and relative humidity (66%) condition. Because the absorption amount of CO2 achieved almost the same loading ratio of K2CO3 (17.6 wt%), the absorption reaction of CO2 by K2CO3 on the honeycomb absorbent seems to be going smoothly. In addition, CO2 absorption breakthrough characteristics of the honeycomb absorbent were analyzed at the temperature range of 50∼80 ℃, and the water vapor was fed to an absorption column before the feeding of CO2 or simultaneously with CO2. As a result, the absorption capacity of CO2 was more enhanced using the water vapor supplying before CO2 than that of simultaneous supplying. It was confirmed by temperature programmed desorption analysis that the KHCO3 produced by the absorption reaction of K2CO3 and CO2 is regenerated by the desorption of CO2 at a temperature of about 128 ℃.
