Description:
The ZSM -5 zeolite particles have been prepared using triethanol amine as structure-directing agent under static hydrothermal condition at 170°C for 7 days. The particles were characterized by X-ray diffraction (XRD), thermogravimetry analysis (TGA), differential thermal analysis (DTA), Fourier transform infrared (FTIR) spectroscopy, N 2 physisorption measurements, and field emission scanning electron microscopy (FESEM). The crystalline ZSM -5 was found at 170°C/7 days as shown by XRD. The vibration bands at around 549 and 1226 cm −1 in the FTIR spectra indicated the presence of double 5-ring in ZSM -5. The exothermic peak at 395°C in DTA curve indicated the removal of structure-directing agent. The BET surface area of the particles was 100 m 2 /g. The FESEM images showed coffin-shaped and broom-like crystals of ZSM -5.
