Zeolite structure and manufacturing method thereof

A manufacturing method of a zeolite structure, comprising:

• a step of mixing zeolite powder obtained by mixing fine zeolite particles having a small average particle diameter and coarse zeolite particles having an average particle diameter which is three or more times the average particle diameter of the fine zeolite particles, an inorganic binding material which binds the zeolite particles constituting the zeolite powder, and an organic binder, to prepare a zeolite raw material;
• a step of extruding the obtained zeolite raw material to obtain a formed zeolite article;
• and
• a step of firing the obtained formed zeolite article to prepare the zeolite structure,
• wherein the step of preparing the zeolite raw material includes the steps of using, as the zeolite powder, zeolite powder containing 40 to 90 vol % of the coarse zeolite particles with respect to the whole volume of the zeolite powder, and adding 5 to 50 vol % of the inorganic binding material to the total volume of 100 vol % of the zeolite powder and the inorganic binding material in terms of a solid content, to prepare the zeolite raw material.
