Production of Biodiesel from oil in the presence of ultrasound waves



According to the environmental pollution caused by emissions from diesel fuel, the use of cleaner fuels such as biodiesel fuels, solar energy and ... are more important. Therefore, more research today, trying to make this type of fuel is from renewable sources. Our country is also among the countries that can invest more in producing biodiesel fuel from vegetable oils. Therefore in this study, the transesterification reaction of sunflower oil with methanol as solvents and reagents in the presence of recyclable mesoporous silica catalyst has been studied. The advantages of this method, is the use of recyclable catalysts based on silica, low response time, and use ultrasound waves rather than thermal energy for the reaction is carried out.
