利用天然矿物原料合成沸石的研究

    RESEARCH ON SYNTHESIS OF ZEOLITES FROM NATURAL MINERAL MATERIALS

    • 摘要: 沸石具有优良的物理化学性能,作为分子筛用途广泛。利用天然矿物原料可合成质优价廉的沸石,极有发展前景。本文对利用天然矿物原料合成沸石及其合成工艺进行了综述,将合成工艺归纳为原料预处理、硅铝质前驱物制备、硅铝质凝胶制备、晶化合成及后期处理等步骤。并指出今后应在晶化机理方面进行深入研究。

       

      Abstract: Zeolites,as molecular sieves,have many uses,due to their excellent properties,The future is expansive to use natural mineral materials to cheaply synthesize zeolites.This article summarizes it and its technique,generalizing its technique as materials pretreatment,silicic-aluminuous precursors making,silicic-aluminous gel making,hydrothermal crystallizing synthesis,and subsequent treatment.And the article points out the research on crystallizing synthesis mechanism should be study deeply.
