METHOD OF PREPARING BETA ZEOLITE Russian patent published in 1998 - IPC

Abstract RU 2116250 C1

FIELD: zeolite synthesis installations. SUBSTANCE: claimed method makes it possible to prepare 100% beta zeolite with high yield. To predissolved tetraethyl ammonium bromide in ammonium hydroxide at NH+4

:TEA⁺ ratio of (21.5-42.5):(7.2-14.5) are added oxides of aluminium, sodium, water and seed crystals of beta zeolite with sizes of 200-300

which are previously calcined at 500-550 C for 6 to 10 hours. The resulting gel is thermostated at 100 to 150 C to recover zeolite from reaction mixture. EFFECT: more efficient preparation method. 2 cl, 1 tbl
