This document summarizes a seminar presentation on producing biodiesel from Jatropha seeds. It introduces Jatropha as a drought-resistant shrub that can grow in poor soils and produce oil-containing seeds for 30-40 years. The objectives are to find an alternative fuel for engines as energy sources are decreasing. The methodology discussed is transesterification, the process used to reduce the viscosity of Jatropha and other vegetable oils to make them suitable for use in diesel engines. The document outlines the processing steps, advantages like providing a renewable domestic fuel, and disadvantages such as current low production levels. It concludes that blending 20% Jatropha biodiesel with diesel could save India 7.3 million tonnes

CONTENTS INTRODUCTION OBJECTIVES WHAT IS JATROPHA? METHODOLOGY PROCESSING ADVANTAGES DISADVANTAGES APPLICATION CONCLUSION REFERENCES
INTRODUCTION •Technology has generally led to greater use of hydrocarbon fuels, making civilization vulnerable to decrease in supply. •Biodiesel is an alternative fuel for diesel engine. •It is domestic, renewable fuel for diesel engine derived from natural oil like Jatropha
OBJECTIVES • The energy sources used in engine are limited and decreasing gradually. So that’s why an alternative fuel for engine is required. • From jatropha seeds jatropha oil can be extracted which have similar properties as diesel.
What is Jatropha ? • Shrub: 2 meters in height • Draught resistant and perennial • Starts producing after first year of plantation • It grows well on low fertility soils Plant
• Seeds contain 50-60% oil (approx. 30% is extractable) • Oil: non-edible • Seed production: 7tons per acre per annum • Jatropha produces seeds for 30-40 years Seed
Methodology • Vegetables oils can’t be used directly in the diesel engine. • It has been found that transesterification is the most effective way to reduce the viscosity of vegetable oils • Transesterification is the process by which biodiesel is produced.

Advantages • Provides a domestic and renewable energy supply. • Biodiesel can be use directly in CI engine with no substantial modification of the engine. • Blending of biodiesel with diesel fuel increases engine efficiency. • The higher flash point of biodiesel makes its storage safer. • Biodiesel degrades four times faster than diesel.
Disadvantage • Low availability due to less production of jatropha in India. • Blends of biodiesel possible upto 20% only. • Biodiesel is less sustainable for use in low temp than petrol and diesel.
Application • Railway usage • Aircraft use • Generating electricity • Vehicles • Removing paint and adhesives
Conclusion • By blending of 20 percent biodiesel with diesel will help India to save 7.3x106 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. • It offers business possibility to agricultural enterprises and rural employment.
