The experimental results show that when TCAR is about 700 ℃ XN for limestone is maximum, and the optimum TCAR for dolomite is about 650℃. Although XN for limestone is much higher than dolomite, the difference of their YN is little when TCAR is in 650~700 ℃. And if TCAL is beyond 1050 ℃ XN for limestone decays sharply, but it is negligible to dolomite. XN for dolomite is far higher than limestone in the high TCAL. XN for limestone decreases with the particle size increasing, and there is an optimum particle size range with particle size increasing which XN for dolomite reaches maximum in. The particle size plays a more important role in limestone carbonation process than dolomite.
