Abstract

Lithium ferrite was investigated with a view to its application as a new CO 2 absorbent capable of absorbing CO 2 at around 500°C and emitting CO 2 at temperatures of less than 750°C. From the TG analysis, equilibrium temperature of lithium ferrite, at which CO 2 absorption apparently stops and emission starts, is found to be around 530°C. This temperature is almost the same as that obtained from thermodynamic calculation and about 200°C lower than those of Li 2ZrO 3 and Li 4SiO 4. The absorption rate increased as the absorption temperature increased up to 500°C. On the other hand, CO 2 emission was completed in about 10 min even in pure CO 2 at temperatures of more than 600°C.
