    Abstract: PURPOSE: A titanium-SAPO-34 crystalline catalyst, a method for preparing the same, and a method for manufacturing light olefin using the same are provided to improve the productivity of the light olefin by improving the crystallinity and the hydrothermal stability of the catalyst. CONSTITUTION: A tetraethyl aluminohydroxide(TEAlOH) solution containing an organic templating agent and an alumina precursor is prepared. Phosphoric acid and water are mixed with the TEAlOH solution to obtain synthetic gel. A silica precursor and a titanium precursor are added in the synthetic gel, and a mixing operation is implemented. The mixed synthetic gel is aged and hydrothermal synthesized to obtain Ti-SAPO-34 gel. Non-reacted precursors are eliminated, and a drying operation is implemented. The Ti-SAPO-34 is plasticized.
