FIELD: technological processes.
SUBSTANCE: invention relates to the preparation of a granular synthetic zeolite type A with a high content of the zeolite phase. Process involves mixing the powdered components in the following amount (in wt%): A-type zeolite 45–55, kaolin 32–50, finely dispersed white carbon 1–5 and wood meal 4–8. Further, the mixture is moistened, mechanically granulated, dried, calcined, hydrothermally crystallized in an aluminate-alkaline solution, washed and dried.
EFFECT: invention makes it possible to obtain a zeolite adsorbent without binders with high mechanical strength and adsorption activity.
