摘要: 为探索采用煤系高岭土合成NaY分子筛的可行性,以内蒙古煤系高岭土为原料,采用水热合成法进行了NaY分子筛合成条件研究。试验确定的NaY分子筛的合成条件为导向剂的加入量为8%、导向剂老化时间12 h、n(Na2O):n(Al2O3)=5.5、晶化时间12 h、晶化温度95 ℃。对最佳合成条件下获得的NaY分子筛样品进行分析表明,合成样品具有典型的NaY分子筛的X射线衍射峰和红外振动谱线,合成的NaY分子筛颗粒均匀,粒径集中在2 μm左右,结晶度和纯净均较高。

Abstract: In order to explore the feasibility of coal measures kaolin synthesis NaY zeolite .Coal measures kaolin was used as raw material to research NaY zeolite synthesize conditions by hydrothermal synthesis method.The NaY zeolite was obtained under the optimal conditions:the guide agent aging time of 12 h,guide agent dosage of 8%,n(Na2O):n(Al2O3) = 5.5,the crystal time of 12 h,the crystal temperature of 95 ℃.Through the analysis of the products obtained under the optimal conditions shows that:the products has the typical NaY zeolite X ray diffraction peak and infrared vibration spectrum,besides their particles are uniform and their particle size concentrated around 2 μm.So the products are high crystallinity,pure NaY zeolites.
