Characterization of Waste Palm Cooking Oil for Biodiesel Production

Zahoor Ullah, Mohamad Azmi Bustam, and Zakaria Man

Abstract—Used cooking oils are of increasing interest as inexpensive feedstock for biodiesel production. In this work, we characterized the used cooking oil collected from the cafeteria in Universiti Teknologi PETRONAS. The spectroscopic analysis was performed for the used and unused cooking oil samples. Comparison of the data indicated that no significance spectroscopic and structural changes occurred for used and unused oil samples. The results indicate high degree of saturation and mono unsaturated fatty acids in the oil. The viscosity and acid value of the used oil was considerably higher than the unused oil. It can be concluded on the basis of our results that the difference in the behaviour and performance of oil is not only due to the main components (triglycerides) but also due to minor components (Vitamin E).

Index Terms—FTIR, 1HNMR, TGA, triglycerides, unused and used palm oil.
