Sažetak(ne postoji na srpskom) This paper refers to an experiment of SO2 absorption to the particles of sorbent CaCO3. Sample mass was 100 g with fractional composition of 500-700 µm and 1100-1300 mm. During the experiment the temperature varied from 200 to 400°C. The aim of this experiment is to examine the influence of lower reaction temperature, the size of sorbent particles, and the reaction time to the degree of SO2 absorption and determining the degree of CaCO3 sorbent utilization. The results show that at the reaction temperature of approximately 200°C and average diameter of sorbent particles '600 mm, the absorption degree of SO2 absorption to the particles of sorbent is between 42-66%. Reaching temperature of 400°C and with the same fractional composition of the sorbent, '600 mm, the absorption degree of SO2 is slightly higher and it is somewhere around 45-78%. With greater diameters sorbent particle of '1200 mm, absorption degree of SO2 is a bit lower. The determined degree of utilized sorbent CaCO3 is considerably lower and it reaches up to 6.87%. The acquired results indicate that besides CaO, Ca(OH)2, and CaMg(CO3)2 it is reasonable to inject the CaCO3 sorbent, in the areas of lower temperatures i. e. in the flue channel of the thermal power plant.
