Title : Sustainable biodiesel production via transesterification of waste frying oil
Abstract:
The biofuel has attracting increasing attention worldwide as a clean energy for the future to substitute conventional fuel, which their production derives from conventional ways that are so expensive and polluant using fossil fuels. The aim of the present study is to valorize an agro-food waste, namely fried oil (80% soybean oil and 20% sunflower oil) by the synthesis of biodiesel. The method used is based on the transesterification reaction of the oil using alcohol in basic homogeneous catalysis. Parametric study relating to temperature, time, stirring speed, type of catalyst and solvent influencing transesterification reaction was studied. To confirm that the biodiesel obtained is of good quality, this latter was analyzed by gas chromatography to determine its composition and their physico-chemical properties were studied. The results of the esterification of this oil show that the quality of biodiesel produced is directly related to the temperature. The physicochemical characteristics in terms of density, viscosity, higher calorific value, pour point, cloud point, freezing point and acid number were determined indicating that physico-chemical properties for the produced biodiesel are comparable to those of petrodiesel according to Naftal standards and EN14214 and ASTM D6751 international standards.
Audience Take Away
- This research will help other professors in their research and also in their teaching. The depletion of fossil resources has directed researchers towards natural resources. Two important issues will be highlighted, namely the environmental issue and the economic issue.
- On the one hand, the raw material used comes from vegetable oils but on the other hand, this used raw material will be used for the production of biofuel.
- This study could provide solutions for recovering used waste and moving from waste to energy.
