    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： The present invention provides a method for preparing dialkyl carbonate from urea or alkyl carbamate and alkyl alcohol using an ionic liquid comprising a cation, which produces a hydrogen ion, and a hydrophobic anion containing fluorine with high temperature stability in the presence of catalyst containing a metal oxide or hydrotalcite. Since the present invention can prepare dialkyl carbonate at a pressure lower than those of existing methods, it does not require an expensive pressure control device and peripheral devices for maintaining high pressure including the installation cost. It is also the method for preparing a dialkyl carbonate with high yield, thus improving economical efficiency. Moreover, the method of the present invention hardly produces any waste during the process and is thus an eco-friendly method.
