dc.description.abstractThis thesis aimed at the production of biolubricant from vegetable oils. The first stage produced methyl ester of the oil and in the second stage; the methyl ester was transesterified with Trimethylolpropane (TMP) in a ratio of 3.5:1 at 1500C to produce the biolubricant. The pour points biolubricant and its blend were significantly improved when compared to that of raw oils. The pour point for Jatropha oil improved from 6.5 to -8 to -13, Moringa oil from 6 to -8 to -15, Castor oil from 5 to -4 to -30 and Cotton seed oil from 4°C to -6°C to -16°C respectively. Similarly the viscosity index of Jatropha oil reduced from 220.70 to 216, Moringa oil from 224.70 to 197.75, Castor oil from 96.42 to 88.32, and Cotton seed oil from 213.12 to 198.57 respectively. As the temperature increased from 300C to 100 the viscosity reduces by 37.97, 53.46, 69.58 and 39.32 cSt. The GC-MS result shows that the oils contained more of unsaturated ricinoleic, and linoleic acid than saturated fatty acid of caproic, capric, palmitic and stearic acid. It was found that the biolubricant produced was comparable to the ISO VG-32 and VG-46 commercial standards for light and industrial gears applications respectivelyen_US
