METHOD FOR PRODUCTION OF GRANULATED ZEOLITE OF FAUJASITE TYPE BASED ON NATURAL CLAY MATERIALS Russian patent published in 1995 - IPC

Abstract RU 2033966 C1

FIELD: processing of natural materials. SUBSTANCE: natural clay material is mixed with neutral aluminum salt, sodium hydroxide, and introduced at the same time into reaction mixture is aluminum hydroxide or silicon dioxide. Mixture is subjected to steam heat treatment and after subsequent thermal activation, it is mixed with aluminosilicate hydrogel to obtain homogeneous mass. Neutral aluminum salt is used in form of aluminum sulfate. Initial clay material is mixed with neutral aluminum salt and sodium hydroxide in mass ratio of 100:0.05:0.02, respectively and steam heat treatment is carried out at 100-250 C for 10-60 min. EFFECT: higher efficiency. 4 cl, 3 tbl
