Effect of Fe metal loading on the character of HZSM-5

Modification HZSM-5 as support material, by Fe metal, has been prepared using two stages impregnation methods. In this method, each amount of Fe metal viz. 0, 3, 6, and 9%w loaded on the HZSM-5. In the first stage, the catalyst precursor was heated and stirred at 30°C for 16 hours, and followed by the second stage viz. heated and stirred of mixtures from the first stage at 80°C for 4 hours. The catalysts obtained were named Fe/HZSM-5, Fe3/HZSM-5, Fe6/HZSM-5, and Fe9/HZSM-5, and the catalyst characterizations had done by AAS, FTIR, XRF, and XRD techniques. The techniques aim to characterize the metal composition, functional groups, and crystallinity. The result showed that the Fe metal composition on HZSM-5, Fe3/HZSM-5, Fe6/HZSM-5, and Fe9/HZSM-5 are 0.218, 2.450, 5.590, and 8.090 wt%, respectively. While based on the FTIR and XRD analysis had been confirmed that the impregnation process to modify HZSM-5 by Fe metal had a negligible impact on the chemical structure and crystallinity of HZSM-5.
