PURPOSE: A method for manufacturing SSZ-74 zeolite and the SSZ-74 zeolite manufactured by the same are provided to apply micro-porosity and meso-porosity to the SSZ-74 zeolite by adjusting the amount of bases during a hydrothermal synthesizing process. CONSTITUTION: Hydrous gel containing silica, the oxide of a trivalent atom, 1,1'-(pentane-1,5-diyl)bis(1-methylpyrrolidine-1-ium) as a structure directing agent, basic materials, and water is prepared(S10). The hydrous gel is hydrothermal reacted to form a solid product(S12). The solid product is calcined at 400-700 degrees Celsius to eliminate the structure directing agent(S20). The oxide of the trivalent atom is selected from a group including aluminum oxide, boric oxide, gallium oxide, indium oxide, zirconium oxide, vanadium oxide, titanium oxide, iron oxide, molybdenum oxide, manganese oxide, and a mixture of the same. |
