Researchs on Synthesis of Zeolite Y From Pyrophyllite

Abstract

用福州叶蜡石,在适量补硅的条件下,可合成出y型沸石产物,用Xrd进行了表征,其硅铝比为4.1~5.0,每克叶蜡石可制出1.2克产品,对焙烧和合成过程进行了分析和讨论,试验结果表明:叶蜡石可作为合成y型沸石的廉价原料,有良好的应用前景。Zeolite Y was synthesised From Fuzhou pyrophyllite under condition of adding an amount of Na_2 SiO_3.The products were characterized by XRD.The ratio of SiO_2/Al_2O_3 equals 4.1 ̄5.0.The per gram pyroaphyllite yield of zeolite Y is 1.2 gram.The process of roast and synthesis were analyzed and discussed.The results of experiments show that the pyrophyllite can act as a kind of low-priced raw material For the synthesis of Zeolite Y and displays good application prospects
