摘要
分形维数是描述分形结构特性的一个重要参数 ,其反映了结构的规则程度。文章通过实验的方法 ,研究了钙基脱硫剂孔结构分形维数的变化特性 ,以及分形特性对脱硫剂的硫化能力的影响。结果表明CaO孔隙的平均孔径越大 ,分形维数会越小 ;
Fractal dimension is an important parameter that reflects the regular extent of fractal structure.By means of experiment,fractal characteristics of pore structure,and influences of fractal properties of pore structure on sulphurization performance are investigated in this paper.Fractal dimension of pore structure in CaO decreased with the increase of the mean pore size,and the amount of inaccessible pore volume formatted in sulphurization reaction increases as the fractal dimension increases.
