Dissertation note: Final Year Report (Bachelor of Chemical Engineering ) -- Universiti Malaysia Pahang Al-Sultan Abdullah - 2024 Abstract: A 7 wt% of Ni catalysts supported on fibrous zeolite-Y was synthesized using a combination of microemulsion and impregnation techniques for the purpose of generating syngas via the ethanol dry reforming process (EDR). The EDR reaction was examined over a temperature range of 600°C to 900°C and various feedstock ratios of ethanol to CO2, including 1:1 and 1:1.5. The spent catalysts underwent characterization and evaluation through XRD, FTIR, BET, and TGA analysis to explore alterations in morphology and coke deposition. The possible reaction mechanism was investigated using in-situ FTIR spectroscopy. The fibrous Ni/Zeolite-Y catalyst exhibited a unique fibrous morphology and demonstrated exceptional catalytic performance in the EDR process. The fibrous structure of FHY contributed to the remarkable distribution of NiO, improved metal-support interface, and strong basicity observed in Ni/FHY. This unique morphology played a crucial role in enhancing the accessibility of Ni active sites, leading to superior activity exhibited by Ni/FHY compared to Ni/HY.
