| 摘 要： | 本文采用水热热压技术研究了海泡石中添加RE-USY分子筛的固化成型条件,同时以XRD、SEM、IR对固化体的结构变化以及表面酸性进行了测定.实验结果表明,在海泡石中添加Y型沸石分子筛容易制成具有一定强度的固化体.成型后,海泡石和分子筛的原有骨架结构保持不变.成型后的固化体含B酸和L酸中心,但B酸酸量较固化前减少,而L酸量增加.

| Abstract: | In this paper, the sepiolite from Hunan province with the addition of RE-USY zeolite was solidified by the hydrothermal hot-pressing technique. The effect of hydrothermal hot-pressing conditions on the compressive strength, density, appearance,structure changing and surface acidity of the solidified bodies was investigated by means of XRD, SEM and IR. The results show that sepiolite can be solidified easily and the solidified bodies keep the framework structure of starting materials basically. The solidified bodies have Bronsted acid sites and Lewis acid sites, but the Bronsted acidity is very weak and the Lewis acidity is stronger than that before solidifying. |
