Abstract
Desulfurization using Ca ion-exchanged brown coal was studied at moderate temperature of 300〜400℃. Ca loading of Ca ion-exchange brown coal was very important factor on desulfurization. The calcium conversions of high Ca loading samples such as 7 and 13wt% were lower than those of lower Ca loading samples. The specific surface areas of high Ca loading samples were lower than those of low Ca loading samples. The diffusion rate of SO_2 gas through the pore in Ca loaded char may affect the calcium conversion.
