METHOD FOR GRANULATION OF ZEOLITE AS SYNTHETIC DETERGENT COMPONENT Russian patent published in 2017 - IPC C11D3/02 C11D3/37 C01B39/02 C01B39/14 

FIELD: chemistry.

SUBSTANCE: zeolite granulating method is described, including zeolite powder is moistening with granulation liquid, an aqueous solution of SokalanCP5 acrylic maleic acid copolymer®, manufactured by BASF, Germany, with a molecular weight of at least 70,000 g/mol is taken as the granulation liquid component, the humidified mixture is stirred until a homogeneous plastic mass is obtained, granules are formed and dried; according to the invention, 33.3-50.0% aqueous solution of acrylic maleic acid copolymer is taken as the granulation liquid, during preparation, the mass ratio of solid zeolite phase and granulation liquid is 5:1, zeolite granulation is performed using a sieve with mesh size of 200 microns, after drying and granulating, zeolite is passed through the sieve with mesh size of 200 microns.

EFFECT: obtaining of granular zeolite with good performance, the preparation of granules with sufficient mechanical strength that do not disintegrate during transportation and have good solubility with the ability to form a stable zeolite suspension with uniform zeolite distribution over the entire solution volume, reduced residual moisture content of zeolite after granules formation.
