Abstract
Absorption and regeneration characteristics of sorbent used in a fluidized-bed process to capture $CO_2$ from flue gas have been measured in a thermo gravimetric analyzer. A sorbent Sorb NH prepared for fluidized-bed process was faster than pure $Na_2CO_3$ 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 $Na_2CO_3$ 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 $Na_2CO_3$ as about 11,320 cal/g mol.
