【摘要】 研究了利用齐齐哈尔珍珠岩制备4A分子筛的工艺,着重讨论了珍珠岩酸处理条件、碱处理、凝胶温度以及凝胶混合物的配比对产品性能的影响,并对所合成的4A分子筛进行了XRD、SEM等结构表征。更多还原

【Abstract】 The process of preparing 4A molecular sieves from Qiqihar pearlite is studied. The discussion is focused on the influences of acidity, time, liquid/solid ratio, alkli treatment, gel temperature and gel mixture proportion on the product properties. The structural characteristics of 4A molecular sieves are tested by XRD and SEM.更多还原
