BiodieselBiodiesel

Bio-diesel is a renewable and environmentally friendly fuel, which is produced from vegetable oil or animal fat through a chemical process.

Nature of BiodieselNature of Biodiesel

Bio-diesel is standardized only as mono-alkyl ester and other kinds of diesel-grade fuels of biological origin are not included.

Oil EconomyOil Economy

Oil import constitutes a major part of our trade deficit and has an enormous impact on our economy and creation of new jobs

We spent annually more than 150,000 crores on import of petroleum

Some day we may be faced with an oil crisis that is not temporary; today oil field discovery and production is on the decline.

Developing a strong market for bio diesel would have tremendous economic benefits

Investments in biodiesel technology may ensure that we have transportation fuel options and we will not be so vulnerable

BIODIESEL FROM BIODIESEL FROM JATROPHAJATROPHA

CAN BIODIESEL WORK IN INDIA?CAN BIODIESEL WORK IN INDIA?

India with just 2.4% of global area supports more than 16% of the human population and 17% of the cattle population

India is one of the largest importers of edible oil

Where do we find the oil for biodiesel?

A sustainable source of vegetable oil is to be found before we can think of biodiesel

Uses of BiodieselUses of Biodiesel

It may be used in fossil diesel as a:– Direct Substitute (rarely done)

– Extender / Mixing Component (mostly performed)

– Additive

ConclusionConclusion

The refined oils seem to perform better in producing bio-diesel. They show slightly greater product yields and lower viscosities, makes them a good option for biodiesel production.

Canola oil is far better than cottonseed oil being used as a bio-diesel raw material.
