(57) Abstract: A binderless zeolite bead molded article having both strong strength physical properties and excellent adsorption performance, a production method capable of easily obtaining the binderless zeolite bead molded article, and this binderless zeolite bead A method for adsorbing and removing a specific component such as water in a gas or a liquid from a gas or a liquid by using a molded body is provided. The zeolite content is 95% or more, In addition, among all the particles, a binderless zeolite bead having an average value of compressive strength of 6 kgf or more of particles having a particle size of 1.7 mm or more is used, and a zeolite, a kaolin clay and an inorganic dispersant are used. After baking a zeolite bead molded body obtained by molding a mixture, a production method of making binderless by contacting with an aqueous sodium hydroxide solution, and in a gas or a liquid using the binderless zeolite bead molded body A method for removing the substance to be adsorbed is used. |
