METHOD OF OBTAINING SYNTHETIC GRANULATED FAUJASITE Russian patent published in 2009 - IPC C01B39/20 

FIELD: chemistry.

SUBSTANCE: kaolin and silicon dioxide are mixed with molar ratio SiO₂:Al₂O₃=(3-4):1, with addition of 10-30% wt of p0owder-like faujasite with crystal size 0.5-2.0 mcm and carboxylmethylcellulose, chemical processing and moistening are carried out until homogenous mixture is obtained, formation of granules, thermal activation and hydrothermal crystallisation in alkali aluminate solution with concentration Al₂O₃=5-50 g/l, Na₂O=70-140 g/l with ratio of granule weight to solution volume equal 1:(3-5), are carried out.

EFFECT: high phase frequency, dynamic adsorption capacity and mechanical strength, efficiency in processes of natural gas drying and sulphur-refinement.
