摘要 脱硫剂孔结构特性对脱硫性能有着重要的影响,其煅烧后的多孔结构是具有自相似性的分形结构。选取4种钙基脱硫剂,在压汞分析实验的基础上,对脱硫剂孔结构的分形特性进行研究,提出了脱硫剂孔隙分形维数的计算方法,并探讨了煅烧温度对分形维数的影响。 The desulfurization properties of desulfurization sorbents are strongly affected by the characteristics of their porous structure. Their porous structure after calcination is a fractal structure with self- similarity characteristics. Four kinds of calcium based desulfurization sorbents are chosen, their fractal characteristics studied, explored with the help of mercury porosimetry pressure tests. A method for calculating the fractal dimensions of desulfurization sorbent＇ s pores is proposed and the influence of calcination temperature on fractal dimensions discussed.
