摘要： The present invention relates to a high-strength silicoaluminophasphate-34 (SAPO-34) microsphere catalyst, a method for preparing the same, and a method for preparing light olefins by using the same, and when described in more detail, the present invention relates to a method for preparing a SAPO-34 microsphere catalyst, including: spray drying a mixed slurry including a matrix, a binder, an additive, and the like to a SAPO-34 slurry prepared by a hydrothermal synthesizing method using various organic templates such as tetraethylammonium hydroxide (TEAOH), and the like alone or in mixtures to prepare microspheres, and firing the microspheres, and to a SAPO-34 microsphere catalyst for a circulating-fluidized bed reactor, prepared by the preparation method. The SAPO-34 microsphere catalyst of the present invention has excellent reaction activity while having high strength, and thus is appropriate for use in a circulating-fluidized bed reactor requiring high strength of the catalyst. Further, the SAPO-34 microsphere catalyst has a long life-span and excellent conversion rate of C1 to C4 oxygen-including compounds (oxygenates), and thus is appropriate for use in the preparation of light olefins such as ethylene, propylene, butene, and the like.
摘要翻译：本发明涉及一种高强度硅铝硅酸盐-S34（SAPO-34）微球体催化剂及其制备方法，以及使用该微球体催化剂的轻质烯烃的制备方法，更详细地说明本发明涉及涉及一种制备SAPO-34微球催化剂的方法，包括：将包含基质，粘合剂，添加剂等的混合浆料喷雾干燥至通过水热合成法制备的SAPO-34浆料，使用各种有机模板如四乙基氢氧化铵（TEAOH）等单独或以混合物形式制备微球，并烧制微球，以及通过制备方法制备的循环流化床反应器的SAPO-34微球催化剂。本发明的SAPO-34微球催化剂具有优异的反应活性，同时具有高强度，因此适用于需要高强度催化剂的循环流化床反应器。此外，SAPO-34微球催化剂具有长寿命和优异的C1至C4含氧化合物（含氧化合物）的转化率，因此适用于制备轻质烯烃如乙烯，丙烯，丁烯，等等。
