Abstract
The manufacturing method includes a mixing step of mixing a plurality of zeolite particles, an inorganic binding material and an organic binder, to prepare a zeolite raw material, a forming step of extruding the zeolite raw material to obtain a formed zeolite article, and a firing step of firing the formed zeolite article to prepare the zeolite structure. The mixing step includes an inorganic binding material containing at least one type of silica sol selected from the group consisting of acid silica sol, silica sol containing silica particles coated with alumina, cationic silica sol, silica sol containing string-like silica particles, and silica sol containing bead-like silica particles. A content ratio of silica particles contained in the silica sol selected from the group is from 10 to 30 mass% with respect to 100 mass% of the zeolite particles.
