HIGH-STRENGTH SAPO-34 MICROSPHERE CATALYST, METHOD FOR PREPARING SAME, AND METHOD FOR PREPARING LIGHT OLEFINS USING SAME |
摘要 |
The present invention relates to a high-strength silicoaluminophosphate-34 (SAPO-34) microsphere catalyst, to a method for preparing same, and to a method for preparing light olefins using same. In detail, the present invention relates to a method for preparing a SAPO-34 microsphere catalyst by spraying a slurry mixture containing a matrix, a binder, an additive, etc., onto the SAPO-34 slurry which is prepared by hydrothermal synthesis using various organic templates, such as tetraethylammonium hydroxide (TEAOH) or the like, wherein the organic templates are used alone or a mixture of the organic templates is used, drying the mixture slurry to obtain microspheres, and firing the microspheres. The present invention also relates to a SAPO-34 microsphere catalyst prepared by the method for a circulating fluidized bed reactor. The SAPO-34 microsphere catalyst of the present invention has a high strength and superior reaction activity, and therefore is suitable for use in a circulating fluidized bed reactor which requires a high strength catalyst. In addition, the SAPO-34 microsphere catalyst of the present invention has a long lifespan, and has a superior C1-C4 oxygenate conversion rate, and therefore is suitable for preparing light olefins such as ethylene, propylene, butane, and the like. |
