摘　　要：以高岭土为原料,经煅烧活化、补硅,在优化的合成条件下,采用原位晶化的方法在高岭土载体上合成出了L沸石分子筛,并用X射线衍射、扫描电镜对合成的产品进行表征。Zeolite L is synthesized from kaolin by in -situ hydrothermal method, with appropriate amount of other eonstituents, sueh as sodium silieate, water, zeolite L initiator and potassium hydroxide. The prepared produet is eharaeterized by XRD, SEM.
