Technology for the Production of Biodiesel from Jatropha Seed

An improved process for the preparation of biodiesel from triglyceride oils through transesterification.

Forward Integration of Jatropha cultivation on wasteland to biodiesel preparation with the aim of attaining fuel of a quality fit for neat application in unmodified engines.

• Jatropha methyl ester (biodiesel) produced complies with the stringent EN14214 specifications.
• The biodiesel in neat form has been used successfully in mobile and stationary diesel engines without any engine modification and down to a temperature of +2 deg.C.
• Mileage obtained with the neat biodiesel is comparable in most cases with that obtained with fossil diesel.
• Euro III emission norms have been met in studies.
• The process can handle variations in Jatropha oil quality without compromising on biodiesel quality.
• The unit operations are simple to operate and maintain.
• All the operations in the core process are at ambient temperature making it an energy efficient process.
• The process is integrated all the way from whole seed to recovery of by-products.
• Zero effluent discharge through integration.
• The process is applicable to other vegetable oils besides Jatropha.
