FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry, namely to obtaining synthetic zeolite of A type. Method of obtaining includes mixing natural clayey mineral-kaoline with pore-former and preliminarily annealed at 550-700°C powder kaoline, taken in quantity 10-30%. Plasticising liquid is added into obtained mixture until homogenous mass is obtained and granules are formed. Then, performed are: drying of granules, thermo-activation, hydrothermal crystallisation, washing and final drying. As pore-former aluminosilicate nano-tubes corresponding in composition to mineral kaolinite, or their mixture with wood powder is used. Hydrothermal crystallisation is realised in solution of sodium hydroxide.
EFFECT: invention ensures possibility of obtaining synthetic granulated zeolite of A type, which has high mechanic strength and adsorbing capacity by water vapours.
