PURPOSE:To obtain a formed zeolite having excellent mechanical strength and high absorption capacity, by forming zeolite powder with a water-glass or clay binder in the presence of an amino acid. CONSTITUTION:Natural or synthetic zeolite powder is mixed with a water- glass binder such as sodium silicate or a clay binder such as kaolin and a water- soluble amino acid such as glycine, alanine, etc. the mixture is kneaded in the presence of water, formed, dried, and baked to obtain the objective formed zeolite. Since the strength of the formed zeolite is remarkably improved and the amount of the binder is reduced by the addition of amino acid, the decrease in the absorption capacity of the formed zeolite can be minimized. |
