常德青峰煤矸石制备A型分子筛的试制研究

Experiment study to A molecular sieve prepared by coal gangue of qingfeng in changde,hunan province

通过化学分析、岩矿鉴定、热重—差热分析、x射线衍射和扫描电镜对湖南常德青峰煤矸石的资源特性进行了研究,基本查明了湖南常德青峰煤矸石的化学成分特征、矿物组成特征及热分析特征,在此基础上,采用直接晶化法进行了A型分子筛的试制研究。

The paper studied the resource characteristics of Qingfeng coal gangue in Hunan Changde by means of chemical analysis, mineral and rock identification, thremogravimetric-clifferential thermal analysis, x-ray diffraction analysis and scanning electron microscopic analysis, ascertained the chemical compositional characteristics, mineral compositional characteristics and thremogravimetric-differential thermal analysis characteristics of Qingfeng coal gangue,on the base of which we simply have made the reserach of A molecular Sieve by the direct crystallization.
