    • The present invention relates to a preparing method of a SAPO-34 molecular sieve containing titanium, a SAPO-34 molecular sieve containing titanium prepared by the method and a preparation method of light olefin from methanol using the SAPO-34 molecular sieve. More specifically, the method of the present invention, wherein a titanium precursor is firstly added and then the phosphoric acid is added unlike an existing method which means a synthetic gel is formed after the titanium precursor is added, and the SAPO-34 molecular sieve manufactured by the method has the same structure of porous chabazite mineral and forms Ti well in a molecular sieve whose catalyst activity is relatively large. In a case of using the SAPO-34 molecular sieve as a catalyst for an MTO reaction which manufactures light olefin from oxygenate compounds like methanol, the SAPO-34 molecular sieve is allowed to improve catalyst activity and catalyst life compared with a Ti-SAPO-34 molecular sieve manufactured by the SAPO-34 and an existing method and to increase yield and selection degree of light olefin.

    • The present invention relates to a zeolite catalyst which is a nano-sized crystal in which zinc and lanthanum are dipped and a method for producing same. More specifically, the zeolite catalyst includes a first particle having a size of 10 to 100 nm and a second particle having a size of 1 to 10 μm. Each of the second particles includes the first particles. The zeolite catalyst comprises: zeolite having a silica and alumina mole ratio (SiO2/Al2O3) of 50 to 80; and zinc and lanthanum that are dipped therein. The zeolite catalyst includes zinc and lantan that are co-precipitated therein as active ingredients of the catalyst in order to increase the selectivity of an aromatic compound, especially BTX. The selectivity of an aromatic compound and BTX can be remarkably increased when the aromatic compound is produced from ethanol using a fixed layer catalyst reactor by means of the co-precipitation and appropriate acid site of nano-sized crystal particles, zinc, and lanthanum.
