| description | The invention provides a preparation method of SAPO-34 molecular sieve. The method comprises the following steps: 1) mixing silicon source, tetraethylammonium hydroxide, aluminium source, phosphoric acid and water, dissolving the materials to form a molecular sieve mother liquor, and performing aging; 2) drying the molecular sieve mother liquor of the step 1), and grinding the product to powder; and 3) mixing the powder of the step 2) and water, and performing crystallization synthesis of SAPO-34 molecular sieve. The method can synthesize nano SAPO-34 molecular sieve under the conditions of low water content and low template, can reduce cost and environmental pollution, has simple and convenient operation and large specific surface area, and has good catalysis performance in the reaction to prepare olefin from methanol.
本发明提供种SAPO-34分子筛的制备方法，包括如下步骤：1）将硅源、四乙基氢氧化铵、铝源、磷酸和水混合溶解形成分子筛母液，并进行老化；2）将步骤1）的分子筛母液烘干，并研磨成粉末；3）将步骤2）中的粉末与水混合后，晶化合成SAPO-34分子筛。本发明所述方法在低水含量，低模板剂条件下合成纳米SAPO-34分子筛，操作简单方便，降低成本，减少环境污染且比表面积大，在甲醇制烯烃反应中 |
