FIELD: manufacturing technology.
SUBSTANCE: invention relates to the preparation of a granular synthetic zeolite of type X with a high content of the zeolite phase. Mixture of 60–78 % type X zeolite, 20–30 % of kaolin and 2–10 % of organic burn-up additive is going through humidity treatment, mechanical granulation, drying, calcination, hydrothermal crystallization in sodium silicate solution, washing and drying of the granules.
EFFECT: invention provides obtaining of zeolite adsorbent without binders with high mechanical strength and adsorption activity.
