    • A solvothermal synthesis process of the SAPO molecular sieves and catalysts prepared thereby are provided. The synthesis process comprises the following steps: a) an organic amine, an aluminum source, a phosphorus source, a silicon source, and water are mixed in a molar ratio of 6-30 : 1 : 0.5-5 : 0.01-1.0 : 0.1-15, to obtain an initial mixture for preparing the SAPO molecular sieves, wherein the molar ratio of water to the organic amine is less than 2.0; b) the initial mixture obtained in the step a) is maintained at 30-60 °C and aged with stirring for not more than 24 hours, to obtain an initial gel; c) the initial gel obtain in the step b) is crystallized at 150-250 °C for 0.5-15 days. The SAPO molecular sieves prepared thereby are used, after being calcined at 400 - 700 °C in air, as catalysts for acid-catalyzed reactions or for conversion reactions of oxygen-containing compounds to olefins.
    • 设置在SAPO分子筛,并由此制得的催化剂的溶剂热合成方法。 合成方法包括以下步骤:a)以有机胺铝源,磷源,硅源,水和在6-30的摩尔比混合的,:1:0.5-5:0.01〜1.0:0.1 -15,以获得在初始混合物用于制备SAPO分子筛,worin的水的摩尔比的有机胺是小于2.0; b)在步骤a)中获得的初始混合物保持在30-60℃并老化搅拌不超过24小时,以获得在初始凝胶; c)该初始凝胶获得在步骤b)在150-250℃下结晶为0.5〜15天。 由此制备的SAPO分子筛的使用,在400煅烧至700℃的空气中,作为催化剂用于酸催化的反应或反应为含氧化合物转化成烯烃后。
