摘要

采用热分析方法对几种贝壳的煅烧特性和固硫特性进行实验研究

在理论分析和实验研究的基础上得到贝壳煅烧反应的动力学模型

并求出表观活化能

结果表明贝壳的表观活化能比石灰石小约 10 0kJ·mol-1.利用扫描电子显微镜观察贝壳断面的微观结构

根据电镜图片比较了各种贝壳与石灰石的比表面积和孔隙率 .最后从孔隙率出发对贝壳固硫效果好的原因进行机理探讨.

Abstract

In this paper

calcination characteristics and desulfurization property of several kinds of shells are studied by using thermogravimetic analysis methods.On the basis of theoretical analysis and experimental study

the kinetic model of shell calcination reaction is obtained and apparent activation energy is calculated and compared with that of limestones.The results indicate that apparent activation energy of shells is approximately 100?kJ·mol -1 lower than that of limestone.By using SEM

the microstructure of shells can be observed.From SEM photos of shells and limestone

this paper compares shells with limestone in specific surface area and porosity.Finally the reason for better desulfurization with shells than with limestones can be explained.
