<p>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 C 1 to C 4 oxygen-including compounds (oxygenates), and thus is appropriate for use in the preparation of light olefins such as ethylene, propylene, butene, and the like.</p> |
