摘要

The growing global demand for renewable energy has led to the search of non-conventional feedstocks for producing biodiesel. Trigonella foenum-graecum, or fenugreek seed, is the subject of this research as a novel potential source for the synthesis of biodiesel. We aimed to discover the possibility of producing biodiesel using Fenugreek seed and determine its fuel properties. Fenugreek seeds were collected, dried, crushed, and oil was extracted; then, the oil was trans-esterified using an alkaline-catalyzed process to produce fatty acid methyl esters (FAME). The obtained biodiesel was analysed for yield, purity, and fuel properties, such as iodine value, calorific value, boiling point, flashpoint, and cloud point. The analyses were conducted strictly with standards ASTM D6751-20a and EN 14,214. Moreover, the relative composition of fatty acid methyl esters was determined using gas chromatography with flame ionization detector. Based on the experimental results, fenugreek-derived biodiesel satisfied most of the international biodiesel standards, and its high percentage of polyunsaturated fatty acids justified its excellent cold flow characteristics. This research supports and confirms fenugreek seed’s potentiality as an acceptable and sustainable feedstock for biodiesel production. Detailed investigation about the optimum reaction parameters for high oil yield and the possibility of industrial scaled-up production is yet to be checked.
