提出了应用高效NaY沸石导向剂快速合成A型沸石的新方法.在合成过程中,NaY沸石导向剂提供了全部硅源(无需另加硅源).与用水玻璃提供硅源的合成方法相比,该法晶化速度快,合成温度低,并可在低碱度条件下合成超细A型沸石.29S i NMR表征和UV Ram an研究表明,高效NaY沸石导向剂中含有大量的六元环等低分子量硅铝酸根前驱体,它们有利于A型沸石成核与晶体生长.
A new method for the rapid synthesis of zeolite A with high efficiency NaY zeolite directing agent was proposed. In the synthesis process, NaY zeolite directing agent provided all the silicon sources without the need of additional silicon sources .Compared with the synthesis method of providing silicon sources with water glass , The method of crystallization speed, low synthesis temperature, and synthesis of ultra-fine A-type zeolite at low alkalinity.29S i NMR characterization and UV Ram an research shows that high-efficiency zeolite NaY zeolite contains a large number of six-membered ring Low molecular weight aluminosilicate precursors, which are good for A-type zeolite nucleation and crystal growth.
