Abstract:
Zeolite Y was synthesized from bentonite via the hydrothermal method. The effects of various parameters
on the synthesize were investigated. The samples were characterized by XRD, XRF, IR, DTG and wet
chemical analysis. The results show that crystallization temperature, aging time and concentration of sodium
hydroxide play important roles in the formation of the zeolite. P zeolite was the competitive phase and
present in most of the products. However, under optimized conditions, such as crystallization temperature
(97 ), aging time (20h), concentration of NaOH (3N), pure zeolite Y with high crystallinity was synthesized.
The results showed that optimization of the process results in a commercial route to synthesize of zeolite Y
from bentonite.
