PREPARATION AND CHARACTERIZATION OF FINE HIGH ACTIVATION HYDRATED LIME

本文报告了制备超细高活性水合氧化钙过程中各种因素.包括添加剂的重量百分比、氧化钙粒径、氧化钙用量、搅拌速度、水浴温度、搅拌时间、添加剂等对吸硫剂比表面积的影响.在制得的超细高活性水合氧化钙基础上.进行了一些物理化学特征的研究,如扫描电镜、X射线能谱分析以及粒径分布等,并且在差热天平上进行了吸硫剂在高温下的吸硫机制的研究.

In this paper,fine,high activation hydrated lime was obtained by means of optimizing experimental conditions during sorbent preparation. Factors influencing specific surface area,include additive weight percentage, CaO particle size, CaO weight, reaction temperature, reaction time and Fe-additive molar fraction. On the basis of prepared sorbent,physico-chemical characterizations, such as SEM(Scan Electronic Microscopy) ,EDAX and particle size distribution were studied. Furthermore . the SO2 adsorption performance of sorbent on the thermogravimetric balance was discussed.
