To maintain ecosystem. To blend with diesel. Blends are indicated by the abbreviation Bxx, where xx is the percentage of biodiesel in the mixture. For example, the most common blend is B20, or 20 percent biodiesel to 80 percent standard. So, B100 refers to pure biodiesel. To reduce fuel costs.Slide 4: History The concept dates back to 1885 when Dr. Rudolf Diesel built the first diesel engine with the full intention of running it on vegetative source. In 1900 he ran the patented engine on any hydrocarbon fuel available - which included gasoline and peanut oil. Scientists discovered that the viscosity ( thickness) of vegetable oils could be reduced in a simple chemical process In 1970 and that it could work well as diesel fuel in modern engine.Slide 5: Biodiesel Biodiesel is a variety of ester-based oxygenated fuels derived from natural, renewable biological sources such as vegetable oils . Biodiesel operates in compression ignition engines like petroleum diesel thereby requiring no essential engine modifications. Unlike fossil diesel, pure biodiesel is biodegradable, nontoxic and essentially free of sulphur and aromatics.Slide 6: Advantages of Biodiesel Biodiesel is environmentally friendly. It can help reduce dependency on foreign oil. It helps to lubricate the engine itself, decreasing engine wear. It can be used in almost any diesel with little or no engine modification. It is safer than conventional diesel. Less global warming.Slide 7: Disadvantages of biodiesel Biodiesel emission increases NOx in atmosphere. Biodiesel behaves as a solvent . Slightly decreases fuel economy . Cost varies according to feedstock used and market conditions.Slide 8: Biodiesel production sources Biodiesel created from renewable sources like New or used vegetable oil and animal fats Algae Oil contained seeds like soya, peanuts , jatropha etc… In this presentation we discuss about production of biodiesel from jatropha curcas plant seeds.Slide 9: Jatropha curcas plant Jatropha curcas is a drought-resistant perennial, growing well in marginal/poor soil. It is easy to establish, grows relatively quickly and lives, producing seeds for 50 years. Jatropha the wonder plant produces seeds with an oil content of 37%. The oil can be combusted as fuel without being refined. It burns with clear smoke-free flame, tested successfully as fuel for simple diesel engine.Slide 10: Jatropha life cycleSlide 11: Pilot biodiesel plant The biodiesel pilot plant consists of Transesterification reactor with heater A stirrer Chemical mixing tank Three glycerol settling tanks Washing tank Properties Jatropha Oil Jatropha biodiesel Diesel Density, g/ml 0.920 0.865 0.841 Viscosity @ 40 o C, Cst 3.5 5.2 4.5 Calorific value, MJ/kg 39.7 39.2 42.0 Flash point, o C 240 175 50 Cloud point, o C 16 13 9Slide 12: Flow chartSlide 14: Conclusion Jatropha biodiesel is ideal solution to meet out higher diesel demand and oil imports. By mixing of 20 per cent biodiesel with diesel will help India to save 7.3x10 6 tones of diesel per year. In India about 33 million hectares of wasteland is available and can effectively be used for cultivation of Jatropha plants. By installing the developed pilot biodiesel plant at each district, dependence on diesel fuel for farm operations can be reduced. It offers business possibility to agricultural enterprises and rural employmentSlide 15: Bibliography http://www.bdai.org.in/ http://www.jatrophabiodiesel.org/ http://www.treehugger.com/ http://www.howstuffworks.comSlide 16: THANK YOU DEDICATED TO MY FATHER You do not have the permission to view this presentation.
