Optimization of process parameters for alkaline-catalyzed transesterification of palm oil using response surface methodology

Biodiesel (fatty acid methyl esters) was synthesized from direct transesterification of vegetable oils, where the corresponding triglycerides react with methanol in the presence of a suitable catalyst. The alkali catalysts are the most common catalyst used in biodiesel industry, because the process...
