Comparison study of biodiesel fuel production from sunflower oil using by ultrasound and heat
نویسندگان
چکیده مقاله:
In this research, a comparison of biodiesel produced by ultrasound and heat methods was investigated. Methanol was used as the alcohol with molarity 3, 6 and 9 and KOH 0.5, 1 and 1.5 wt.% As a catalyst. In ultrasound technique, five vibrating pulse levels and three time levels were used. The results indicate that biodiesel produced by ultrasound in some properties includes a flash point of about 9% increased and the amount of viscosity, carbon residue and water content in fuel decreased by 27%, 50% and 5%, respectively. The biodiesel cloud point produced by the heat treatment method -2 and ultrasound waves 7 was obtained. It should be noted that the fuel produced in both methods can be used as a standard fuel in the engine. It was also found that ultrasonic waves are more appropriate than heat treatment due to the need for less time and better quality characteristics.

متن کاملOptimization of Biodiesel Production by Chemical Trans-esterification of Sunflower Oil
Vegetable oils and fats in comparison with diesel fuel have high viscosity, by transesterification method the viscosity of oil can be decreased. Transesterification of triglyceride with alcohol is one of the methods for production of biodiesel. In this study sunflower oil, methanol and ethanol, with molar ratio of (1:3, 1:4, 1:6, 1:8) and temperature (40, 50, 60 º C) were dependent parameters e...
