Abstract
연소기체로부터 이산화탄소를 흡수하는 유동층 공정에 사용되는 흡수제의 흡수 및 재생 반응특성을 측정 및 고찰하였다. 유동층 공정을 위해서 제조된 흡수제 Sorb NH의 흡수 및 재생 반응속도는 순수한 Na2CO3보다 더 빨랐다. 흡수반응에서 Sorb NH의 겉보기 활성화에너지는 .10,100 cal/g mol, 순수한 Na2CO3의 겉보기 활성화에너지는 .12,200 cal/g mol이었다. 재생반응에서 Sorb NH의 겉보기 활성화에너지는 약 12,050 cal/g mol, 순수한 Na2CO3의 활성화에너지는 약 11,320 cal/g mol이었다.
Absorption and regeneration characteristics of sorbent used in a fluidized-bed process to capture CO2 from flue gas have been measured in a thermo gravimetric analyzer. A sorbent Sorb NH prepared for fluidized-bed process was faster than pure Na2CO3 in absorption and regeneration reaction rate. Activation energy of apparent absorption reaction of sorbent Sorb NH was estimated as .10,100 cal/g mol and that of pure Na2CO3 as .12,200 cal/g mol. Activation energy of apparent regeneration reaction of sorbent Sorb NH was estimated as about 12,050 cal/g mol and that of pure Na2CO3 as about 11,320 cal/g mol.
