Biodiesel, a mixture of fatty acids methyl esters (FAME), is a feasible non fossil fuel for diesel engines to reduce the CO2 footprint of the transportation sector. The kinetics of the methanolysis of rapeseed oil over lime catalyst was studied in a batch reactor for low reaction temperatures. S-shape curves with a long induction period were observed. FAME yield was only measurable for reaction times > 90 min. CaO was gradually converted into calcium hydroxide, calcium methoxide, and calcium diglyceroxide. The CaO to Ca(OH)2 conversion step was responsible for the reaction delay. Each calcium phase contributed differently for the global methanolysis reaction. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference PRES (Prague, Czech Republic 8/25-29/2012).
