摘要:

以钾长石粉体为原料,通过水热分解、酸溶等过程破坏钾长石晶体结构,得到铝硅滤渣,再补充硅酸钾水玻璃,在适宜条件下水热合成L型分子筛。研究了导向剂、硅铝摩尔比、钾硅摩尔比以及晶化温度和时间条件对合成L型分子筛的影响,并对L型分子筛制品进行表征。结果表明:合成产物为单一物相的L型分子筛,结晶效果良好,分子筛晶体呈短柱状,晶粒长约1 μm,直径为100~500 nm,比表面积为327.53 m2/g。

L-type molecular sieve was indirectly synthesized under proper conditions using potassium feldspar powder. Aluminosilicate with a higher chemical activity was acquired after hydrothermal and acid treatment on the powder, and then potassium silicate water glass was added in the synthesis. The influences of guiding agent, SiO2/Al2O3 mole ratio, K2O/SiO2 mole ratio, crystallization time and temperature on the synthesized L-type molecular sieve were investigated. The L-type molecular sieve product was characterized by chemical analysis, X-ray diffraction, infrared spectrscopy, scanning electron microscope and specific surface area measurement, respectively. The results show that the pure L-type molecular sieve crystals with a high crystallinity are prepared. The molecular sieve grains are mainly short column-shape with the size around 1μm in length and 100–500nm in diameter, and a specific surface area up to 327.53m2/g.
