| dc.description.abstract | Biodiesel is an alternative diesel fuel that is produced from vegetable oils and animal fats. Generally, it is
formed by transesterification reaction of triglycerides in the vegetable oil or animal fat with an alcohol. In
this work, esterification reaction was carried out using oleic acid, methanol and sulphuric acid as a
catalyst by reactive distillation method. In order to determine the best conditions for biodiesel production
by reactive distillation, the experiments were carried out at different temperature (1000C, 1200C, 1500C
and 1800C) using methanol/oleic acid molar ratios (1:1, 5:1, 6:1, 7:1, 8:1), catalyst/ oleic acid molar ratios
(0.5%wt, 1%wt, 1.5%wt and 2%wt) and reaction times (15, 30, 45, 60, 75 and 90 minutes). Result show
that at temperature 1800C, methanol/ oleic acid molar ratio of 8:1, amount of catalyst 1% for 90 minute
reaction time gives the highest conversion of oleic acid above 0.9571. Biodiesel product from oleic acid
was analysed by ASTM (American Standard for Testing Material). The results show that the biodiesel
produced has the quality required to be a diesel substitute. | en_US |
