교반셀에서 측정한 아민첨가 암모니아수 흡수제의 이산화탄소 흡수 반응 속도 측정

Absorption rate of carbon dioxide into aqueous ammonia absorbent(10 wt%) was measured in the temperature range from 293 K to 337 K using a stirred-cell reactor. The reaction rate constant was correlated with the Arrehnius equation and the activation energy was 50.42 kJ/mol. absorption rate into modified ammonia absorbent was also investigated. For the modified ammonia absorbent, 1 wt% sterically hindered amines of 2-amino-2-methyl-1-propanol(AMP), 2-amino-2-methyl-1,3-propandiol(AMPD) and 2-amino-2-ethyl-1,3-propandiol(AEPD) were used as additives. The absorption rate increased by adding 1 wt% of the amine additive, in the case of AMP additive, the absorption rate enhanced by about 53%.
