| Summary: | The use of renewable energy sources is important today due to the reduction of fossil fuel sources and the increase in environmental pollution. Biodiesel is one of the types of renewable energies. By 2020, 20% of the fuel used is from renewable sources, Biodiesel is one of the most important strategies to complete these choices and achieve the goal. Biodiesel as biofuel can be used in diesel engines in combination with pure diesel and thus improves combustion conditions and reduces emissions. Biodiesel is produced from different biomass in different ways and processes, this depends on the potential of the area in question and the availability of bio-resources. On the other hand, the technology used in biodiesel production is also important. Given the technology and biomaterials used to produce biodiesel, economic cost and production efficiency will be achieved. Therefore, in the face of increasing demand for biodiesel production, it is important to provide a suitable way to commercialize the biodiesel production process. In this regard, different methods of biodiesel production from different sources are investigated in this research, in order to find the appropriate method for achieving a biodiesel production process. Based on the results of this study, biodiesel production depends on the conditions and availability of primary biofuels, but in general biodiesel production from non-food sources with alkali catalysts are of commercial importance in the process of trans-esterification; this method produces high-efficiency biodiesel (about 98%) and is economically superior to other methods. |
