Electrochemical Characterization of Biodiesel from Sunflower Oil Produced by Homogeneous Catalysis and Ultrasound

Comparison study of biodiesel fuel production from sunflower oil using by ultrasound and heat

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 abou...

Preparation and Characterization of Biodiesel Produced from Recycled Canola Oil

The purpose of this paper is to evaluate the feasibility of using recycled canola oil as raw material to produce ASTM standard biodiesel. Two-step reaction, acid-catalyzed esterification followed by alkali-catalyzed transesterification, was performed. The high level of free fatty acids ( FFA) in the recycled canola oil was reduced to less than 1% by acidcatalyzed esterification with 40/1 molar ...

The Study of Biodiesel Characterization Obtained from CapparisSpinosa Oil Seed

Biodiesel is usually produced from food-grade vegetable oil using trans-esterification process. As an effective factor on the biodiesel characteristics of the biodiesel is the kind of feedstock which is used, so finding a proper feedstock for using initially has an important role for different places. So, in this research, disposal substances of Capparis Spinosa are used as a feedstock for prod...

Microbial Biodiesel Production - Oil Feedstocks Produced from Microbial Cell Cultivations

Optimization 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...
