Title: HIERARCHICAL EU-2 TYPE ZEOLITE HAVING BOTH MICROPORES AND MESOPORES, AND PREPARATION METHOD THEREFOR
Abstract:
The present invention provides a method for preparing hierarchical zeolite and hierarchical zeolite prepared thereby, the method comprising the steps of: carrying out a reaction of a mixture containing water, a silica precursor, an alumina precursor, a pH adjustment material, at least one structure-inducing material, and at least one surfactant; and carrying out drying and heat treatment, wherein the structure-inducing material and the surfactant have different carbon atoms while the surfactant has more carbon atoms than the structure-inducing material.
