SYNTHESIS OF MOR TYPE ZEOLITE WITH COLLOID SEED
The influence of the composition and amount of colloid seed, the temperature and duration of preliminary aging, and further crystallization on the physicochemical properties of the aluminosilicates formed are studied. A method for the synthesis of a high-purity MOR type zeolite and a degree of crystallinity close to 100% with a crystal size of not more than 6 μm has been developed. It was found that crystallization using a colloid seed, which is an alkaline colloidal silicoaluminhydrogel, forms the most uniform and small crystals. It is established that an increase in the preliminary aging temperature from 30 to 60 °C makes it possible to ensure a uniform composition of the reaction mixture and to obtain MOR type zeolite of high crystallinity and phase purity.
