In order to develop an efficient absorbent of SO_2 in the fluidized bed coal combustor, coal char-supported CaCO_3 was prepared from Oyster. The absorption behavior of the absorbent for SO_2 (840ppm) was examined using a fixed bed rector at 900℃. The performance of absorbent can be evaluated in terms of the utilization efficiency of calcium in the absorbent. The utilization efficiency of commercial CaCO_3 was 42.2%. When coal char-supported CaCO_3 was used in the absorption of SO_2, the utilization efficiencies of calcium remarkably increased to 85.1%.
