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

Abstract RU 2033967 C1

FIELD: processing of natural materials. SUBSTANCE: natural clay material is mixed with neutral aluminum salt and sodium hydroxide and at the same time, aluminum hydroxide is introduced in mixture. Then, 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 at mass ratio of 100: 0.05: 0.02, respectively. Steam heat treatment is carried out at temperature of 100-250 C for 10-60 min. EFFECT: higher efficiency. 3 cl, 3 tbl
