应用控制成核和晶体生长在不同条件下进行的方法(两步法),原料配比不变,定量加入铝,合成出SiO_2/Al_2O_3为20—3400的ZSM-11沸石;其成核和晶化阶段在同一体系中进行(一步法),产物SiO_2/Al_2O_3在30—320之间。以B、Ga、In和T1代替Al,以及在无Na体系中也合成出ZSM-11沸石。本文给出典型产品的X-射线衍射图、扫描电镜照片、红外骨架振动谱图、热谱图、对正己烷和水的吸附量,以及晶化动力学曲线和反应混合物中SiO_2/Al_2O_3对晶速度的影响。
Application of controlled nucleation and crystal growth under different conditions (two-step method), the same ratio of raw materials, quantitative addition of aluminum, synthesis of ZSM-11 zeolite with a SiO 2 / Al 2 O 3 of 20-3400; its nucleation and crystallization In the same system (one-step method), the product SiO 2 / Al 2 O 3 is between 30-320. Al was replaced by B, Ga, In and Tl and ZSM-11 zeolite was also synthesized in Na free system. In this paper, X-ray diffraction patterns, scanning electron micrographs, infrared framework vibration spectra, thermal spectra, absorption of n-hexane and water, as well as the crystallization kinetics curve and reaction mixture of SiO 2 / Al 2 O 3 on the typical products The impact of speed.
