Synthesis and Characterization of MOR Zeolite with Rod-assembled Morphology
Keywords:
Zeolite, Mordenite, Hydrotermal, Rod-assembledAbstract
Zeolite is a microporous crystalline aluminasilicate compound with uniform and well-organized pore
sizes. These characteristics make zeolites an important heterogeneous catalyst for the petroleum
refining and petrochemical industries. Mordenite (MOR) is a member of zeolites which is commonly
used as an important catalyst in the petrochemical industry, for example catalytic reactions, such as
hydrocracking, hydroisomerization, alkylation, reforming and dewaxing. Mordenite zeolite with
assembled rod morphology was synthesized without using zeolite seeds and organic structure directing
agent (OSDA). Synthesis of mordenite zeolite was carried out with a molar composition ratio of SiO2
: Na2O : H2O : Al2O3 = 1 : 0.177 : 30 : 0.062 using the hydrothermal method at a temperature of 180
oC for 3 days. The resulting samples were characterized by XRD, SEM, ATR-IR and XRF. The results
showed that MOR zeolite was successfully synthesized. This result can be seen from the XRD data of
the samples obtained, where typical diffraction peaks from MOR zeolites were detected. In addition,
SEM characterization results show that the resulting MOR zeolite has a rod-assembled morphology.
These results show that MOR zeolite with rod-assembled morphology was successfully synthesized
both without the help of zeolite seeds and OSDA.
