A method of preparing a ZSM-5 zeolite, comprising: heating a mixture containing a silica source, an alumina source, a neutralizer, and a crystalline ZSM-5 nucleus to prepare a first solution in a solution state; Preparing a reaction mother liquor by mixing a second solution including a salt with the first solution; And continuously supplying the reaction mother liquor to a hydrothermal synthesis reactor, thereby providing a method for preparing a ZSM-5 zeolite that satisfies Equation 1 below. [Equation 1] 0.20≤W a / W b ≤0.40 |
