摘要：Fractal geometry was used to describe the calcination of limestones and the sulfur- removal process performed in TGA instrument, and the fractal dimension was calculated through the nitrogen adsorption. The effect of calcination of limestones on the porous structure and fractal dimension of calcined limestones was investigated, and the highest value of fractal dimension 2.72 can be obtained at 850.. The fractal dimension will reduce with the increase of limestones particle size. The fractal dimension of calcined limestones has a significant influence on the sulfurremoval reactivity. It can be stated that the highest reaction reactivity can be obtained when the calcined limestone has a moderate fractal dimension of 2.70.
