Abstract: The present invention relates to a manufacturing method for a layered mesoporous SAPO-34 molecular sieve and to a manufacturing method for light olefin using the layered mesoporous SAPO-34 molecular sieve manufactured thereby and, more specifically, to a manufacturing method for a layered mesoporous SAPO-34 molecular sieve comprising: (Step 1) a step of adding 1.0-2.0 moles of silica composites (based on SiO_2) based on 1 mole of alumina precursors (based on Al_2O_3) as a step of mixing silica composites including organic templates and silica precursors, alumina precursors and water; (Step 2) a step of manufacturing synthesis gel by adding phosphoric acid and synthetic templates in a mixed solution manufactured in step 1 and stirring the same; (Step 3) a step of manufacturing SAPO-34 sieve by performing hydrothermal synthesis on the synthesis gel manufactured in step 2; and (Step 4) a step of sintering the SAPO-34 sieve manufactured in step 3. The manufacturing method for SAPO-34 according to the present invention has excellent life expectancy in MTO reaction compared with that of a catalyst using existing SAPO-34 since SAPO-34 sieve with small crystals of uniform distribution by controlling the amount of silica composites and reducing the amount of water during reaction and improves productivity when light olefin is manufactured by using the same as a catalyst.
