NaY zeolite was obtained by providing a high SiO 2 content in the starting material. This could be facilitated by calcining the kaolin at a high temperature or by adding other an SiO 2 source, such as sodium silicateA s. eed is needed in NaY zeolite synthesis to accelerate crystallization of the NaY zeolite. Accordinglythe , the NaY

Silanol groups and EFAL species are found to be responsible for the 2 better performance of nanocrystalline NaY relative to commercial NaY zeolite. Thus the increased external surface of nanocrystalline zeolites can be utilized as a reactive surface with unique active sites for catalysis.

The amount of chromium retained in NaY zeolites in competitive systems is slightly smaller than in single ion-exchange systems. On the other hand, a large decrease in chromium uptake was observed in NaX zeolite. The dynamic selectivity for NaY zeolite should be written as Cr 3+ > Mg 2+, Cr 3+ > Ca 2+ and Cr 3+ > K +.

In chemistry, zeolites are used to separate molecules (only molecules of certain sizes and shapes can pass through), and as traps for molecules so they can be analyzed. Mobile homes for sale by owner in maJun 29, 1993 · An aqueous suspension of zeolite NaY is treated in with sodium hydroxide solution. The treated zeolite NaY is subsequently dealuminized with silicon tetrachloride. NaY Zeolite, a kind of alkali silicon aluminate, is Y-type crystal sodium zeolite. It can adsorb molecules whose critical diameters are no greater than 10 angstrom. It is used for catalytic cracking catalysts preparation, drying dehydration, hydrogen desulfurization, the catalysts support, the purification of gases of oil refining and chemical ...
