Abstract

Biodiesel has earned a remarkable of attention as a renewable, biodegradable, and non-toxic alternative to fossil fuels. The multipurpose plant known as Jatropha curcas which contains a lot of oil and can be consider as non-edible oil. The main objective of the current research work is to study the effects of acid esterification of this highly Free Fatty Acid (FFA) content of oil in order to reduce acid content during transesterification process. Acid esterification process would be introduce using sulphuric acid (H₂SO₄) to reduce the high fatty acid of the feedstock. The best molar ratio alcohol to oil is 12:1 with 1% v/v acid sulfuric (H₂SO₄), which is value FFA is 0.18 mg KOH/g. Reduction percentage of FFA will be analysed according to ASTM D6751 and EN 14214.
