METHOD OF PREPARING CRYSTALLINE ZEOLITE Russian patent published in 1999 - IPC

Abstract RU 2137713 C1

FIELD: sorbents. SUBSTANCE: crystalline zeolite is prepared from reaction mixture containing water in amounts only sufficient for that, when desired, specified shape could be imparted to reaction mixture. The latter is heated under crystallization conditions in absence of external liquid phase so that, before drying crystals, there is no need for removing excess liquid from crystallized material. EFFECT: reduced amount of water needed for crystallization and enabled formation of shaped zeolites with no binder added. 42 cl, 15 ex
