제목 Study the effect of synthesis of (silico-)aluminophosphate EMM-8 zeolite in the presence or absence of HF
초록  EMM-8 zeolite, with SFO topology, having 2-dimensional intersecting channel system with one 8-membered ring channel perpendicular to another 12-membered ring exhibits a high surface area. This material may be a potential molecular sieve for gas separation and purification. In this work, we prepared AlPO/SAPO-EMM-8 zeolite by hydrothermal synthesis in the presence or absence of fluoride ions using gel composition: (0-0.2)SiO2:1Al2O3:0.8P2O5:(0-0.5)HF:2.0DMAPy:40H2O. Here, DMAPy is N,N-dimethylamino-4-pyridine. Different sources of silica and alumina were used here in order to form zeolites of high crystallinity. The synthesized materials were characterized by XRD, BET and SEM-EDX technologies.
