摘要:
以热重天平(thermogravimetric analyzer,TGA)为实验台,采用N2吸附法测定孔结构参数,研究了硫化反应中钙基脱硫剂不可进入孔隙的形成、孔隙分形维数以及分形结构的变化特性等.结果表明:脱硫剂中不可进入孔隙的形成主要出现在硫化反应的开始阶段; 随着硫化反应的进行,脱硫剂孔结构的分形维数不断减小,且孔隙分布与分形维数之间满足Friesen关系方程.
Abstract:
Experiment was carried out in a TGA(thermogravimetric analyzer), and pore parameters were measured with N2 absorption. The inaccessible pores, fractal properties and fractal dimension changes during sulfation were also investigated. Results show that the formation of inaccessible pores occurs in the initial reaction stage mostly; fractal dimensions decrease continuously in the process of sulfating, and the relationship between the fractal dimension and pore distribution meets the Friesen equation.
