| Summary: | Palm oil, one of the most widely used vegetable oils, offers significant potential as a sustainable feedstock for biofuel production. This study explores the deoxygenation of palm oil using glycerol as a hydrogen donor, with nickel‑molybdenum (NiMo) catalysts supported on commercial alumina (Al2O3), and zeolite (HZSM-5) comparing with self-prepared zirconia (ZrO2). The catalysts were synthesized via incipient wetness impregnation and evaluated for their performance in biofuel production. NiMo/Al2O3 exhibited the lowest oxygen removal efficiency (68.5 %), while NiMo/HZSM-5 achieved a higher oxygen removal (74.3 %) but also demonstrated the highest coke formation. The type of support material influenced the resulting biofuel range, with NiMo/HZSM-5 and NiMo/ZrO2 favoring jet fuel production, whereas NiMo/Al2O3 was more suitable for diesel production. Notably, NiMo/ZrO2 exhibited the highest performance in palm oil deoxygenation while minimizing coke formation. These findings highlight NiMo/ZrO2 as a promising catalyst for efficient and stable biofuel production, with the support material significantly influencing product yield and fuel quality. |
