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. ^ 19 ex, 1 tbl |
