Abstract
FIELD: methods for production of zeolite of Y-type used as adsorbent and catalyst in oil refining and petrochemical industries. SUBSTANCE: method for production of zeolite of Y-type includes reaction of mother liquor after product crystallization and its separation with solution of aluminium sulfate at pH 7.5-8.5 and temperature of 20-60 C. Obtained sediment of amorphous alumosilicate is separated from filtrate and mixed with sodium silicate. Then, mixture is subjected to simultaneous reaction with aluminium sulfate and alkali for 30-120 min with their concurrent adding. EFFECT: reduced product cost with preservation of its adsorption capacity, fraction and chemical composition. 3 tbl
