Technology for the production of biodiesel from Jatropha seed

  • IPR
    IPR Status & Details:
  • US 7,666,234 PCT/IN 04 / 00329 IN 2056/DEL/2004
Application/Uses/Problem being addressed

The biodiesel can be used either in blend or neat form in mobile and stationary diesel engines in place of fossil diesel without any engine modification. It can replace fossil diesel and it is alternative source of renewable energy

Using this technology, a world class biodiesel can be produced with which it is possible to mitigate the environmental pollution by having low pollutants in the exhaust and carbon dioxide generated will be utilized by the vegetation for its growth

Salient Technical Features including Competing Features/ Impact
  • 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 +2oC.
  • 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.
    • TRL Level & Scale of Development:
    TRL 6

    On plant scale ( 1TPD)

    Business scope & opportunity (in terms of scale, cost, market etc.):

    In view of cleaner environment, in particular in terms of climate changes, huge opportunity exists for shift in bio-based fuels market

    Environmental Considerations:

    Zero effluent discharge as all by-products, including catalyst, are recovered in saleable form or recycled in integrated process. Using this technology, a world class biodiesel can be produced with which it is possible to mitigate the environmental pollution by having low pollutants in the exhaust and carbon dioxide generated will be utilized by the vegetation for its growth.
