چکیده مقاله:
SAPO-34 molecular sieves were successfully synthesized using TEOS (Tetraethyl orthosilicate) as a
silica source. The influence of hydrothermal synthesis duration on the final product purity was investigated.
Pure SAPO-34 could be obtained while duration of hydrothermal synthesis will be more than 40 hours at 458
K. The products were characterized by XRD patterns and FT-IR spectra techniques. It was found that SAPO-
34 synthesis with TEOS as silica source will produce smaller particles than conventional procedures for
SAPO-34 synthesis do on view of the fact that TEOS will generate Ethanol as a by product of hydrolyze
process, and it will act as a surfactant which is the main reason for SAPO-34 particles size reduction.
