Study on Preparation Zeolite X from Stellerite

摘要

Natural Stellerite has a big reserve volume,but has some shortcomings which are irregular ducts and Connotation impurities and so on.So,it is necessary to use Stellerite to prepare zeolite X for enhancing purity and property.It tests Products by XRD,FT-IR and Stereo Microscope.The study shows that optimum parameter is n(SiO2)/n(Al2O3)=3,n(Na2O)/n(SiO2) =1.1-1.2 and n(H2O)/ n(Na2O)=30-40.The gel ages at room temperature for 12 h,and then keeps at 95 °C for 7h.The pure zeolite X could be prepared.
