FIELD: chemistry, technological processes.
SUBSTANCE: in water suspension of caolin solutions of acidified aluminium sulfate and powder-like starch or carboxymethylcellulise in amount 2-3% wt are introduced. Amount of caolin in mixture is 75-85% wt. Amount of produced synthetic alumosilicate in mixture is 15-25% wt. Suspension is subjected to dispersive drying at temperature 350°C. Dry microspherical granules are calcinated. Then calcinated granules are crystallised in alkaline aluminate solution. Crystallised microspherical zeolite of A type is washed with water from excessive alkali and dried.
EFFECT: zeolite granules have high wear resistance, phase frequency and adsorption capacity.
