【摘要】：以酸洗后的金尾矿为硅源,添加NaOH制备碱熔熟料,加入Al(OH)_3调节硅铝比,通过水热合成法制备了4A分子筛。研究了原碱比、晶化温度对4A分子筛合成的影响。XRD和SEM分析表明,实验制得的4A分子筛结晶性能良好,纯度较高,微观形貌为规则的立方体颗粒,粒度分散均匀且颗粒大小均一,平均粒径约为3μm。
[Abstract]:4A molecular sieve was prepared by hydrothermal synthesis using gold tailings after acid washing as silicon source, adding NaOH to prepare alkaline clinker and adding Al (OH) _ 3 to adjust the ratio of Si to Al. The effects of alkali ratio and crystallization temperature on the synthesis of 4A molecular sieve were studied. XRD and SEM analysis showed that the obtained 4A molecular sieve had good crystallinity, high purity and regular microstructure. The particle size is uniform and the average particle size is about 3 渭 m.
