摘要
以孔径分布密度函数和孔长度分布函数为基础,结合氧化钙比表面积和孔隙率等参数的测量,建立了钙基脱硫剂煅烧过程中产物CaO孔隙分布模型及孔隙分布变化模型,并对其分布特性及其演化过程进行了研究。结果表明:该模型可以较完整地描述钙基脱硫剂的孔径及其分布。
Based on the density function of pore size distribution and the pore length distribution function, and taking into consideration measured data, such as specific surface area and rate of porosity, a mathematical model has been built for pore distribution and for pore distribution variation, of process produced CaO, during calcination of calcium-based sorbents, with which distribution characteristics of pores and their development process have been studied. Results show that with these models, pore size and its distribution, in calcium-based sorbents, can readily be described.
