| Research Abstract |
Ceramic composites for CO_2 absorption in the middle temperature range were fabricated. The ceramic composite composed of LiFeO_2 particles chemically absorbing CO_2 and CeO2 nanoparticles enhancing the CO_2 separation rate of LiFeO_2. The CO_2 absorption ability increased asthe temperature increased in the temperature range of RT. to 500℃. The CO_2 absorption rate of thecomposite was also examined in a gas mixture of N_2 and CO_2 using a gas chromatograph attached to an electric furnace with a ceramic tube. As a result, a concentration of CO_2 at 400℃ decreased by 10%.
