Abstract:Biodiesel produced by transesterification reaction of triglycerides with short chain alcohols, recently attracts attention as an alternative fuel due to its certain properties such as being renewable, having less sera gas emissions. Studies focusing on using heterogeneous catalysts in biodiesel production has been more common in compariosn with using homogeneous catalyst due to the following disadvantegs: non-reusable catalyst, difficulties in separation byproduct and need of large amounts of water in the purification process. In this study, activity of Marl as the catalyst of the transesterification reaction,were examined in the 55-80 0C temperature range and at different stirring speeds 400-600 rpm molar rates (methanol / waste oil = 6/1) . In this study as well as effects of different amounts of catalyst (0,05,05,1%) on triglyceride conversions were investigated. The highest conversion (99%) was reached in following condition: NaOH and Marl catalyst used were as much as 1 % of oil , methanol / waste oil molar ratio was 1/6, the stirring speed at 600 rpm and reaction temperature was 55 0C.
