Biodiesel: A Cost-effective Fuel Using Waste Materials
The main disadvantage of biodiesel is its high price. The price of biodiesel depends on various factors such as the price of oil, methanol, catalyst, and labor. Among dif-ferent economic factors, oil accounts for the largest share of input costs of biodiesel production. In this study, first, suitable heterogeneous catalysts were identified for biodiesel production. Several studies were carried ...
متن کاملMicroreactors - Portable Factories for Biodiesel Fuel Production
Nowadays, when fossil fuel recourses are decreasing rapidly, biodiesel fuels are becoming more and more interesting. Being environmentally beneficial, biodegradable, non-toxic and with low pollution emission makes biodiesel interesting for consumption. Various methods have been reported for biodiesel production such as microemulsification, pyrolysis and transesterification. Main problems of thi...
متن کاملCorrection to " Global Sale of Green Air Travel Supported Using Biodiesel " — the Fossil Fuel Consumption Associated with Biodiesel Production Fossil Fuel Consumption Associated with Biodiesel Production
Current biodiesel production practices entail the consumption of fossil fuels. The original proposal for green air travel supported using biodiesel (Wardle 03), included a mechanism to offset this consumption, so that the resulting green air travel was, in effect, " fossil free. " It is now recognized that the mechanism was not properly designed, and, in the present paper, a revised mechanism i...
متن کامل“Designer” Biodiesel: Optimizing Fatty Ester Composition to Improve Fuel Properties†
Biodiesel is a domestic and renewable alternative with the potential to replace some of the petrodiesel market. It is obtained from vegetable oils, animal fats, or other sources with a significant content of triacylglycerols by means of a transesterification reaction. The fatty acid profile of biodiesel thus corresponds to that of the parent oil or fat and is a major factor influencing fuel pro...
متن کاملOptimization of Effective Parameters of Pongamia Pinnata (Karanja) Biodiesel Using Taguchi Method
Biodiesel is an alternative fuel for diesel engines that is produced by chemically reacting vegetable oil or animal fat with an alcohol such as ethanol or methanol in the presence of catalyst. The growing interest in biodiesel (fatty acid methyl ester or FAME) is because of the similarity of its properties when comparing with diesel fuel. Karanja (Pongamia pinnata), which is one of the source o...
متن کاملComparison 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...
