BIOFUELS

A BIOFUEL IS A TYPE OF FUEL WHOSE ENERGY IS DERIVED FROM

BIOLOGICAL CARBON FIXATION.IN OTHER WORDS, FUEL WHICH PRODUCED FROM RENEWABLE

BIOLOGICAL RESOURCES SUCH AS PLANT BIO MASS AND TREATED

MUNICIPAL AND INDUSTRIAL WASTE .

WHAT IS BIO FUEL?

WHY BIOFUELS?

Therefore, there are many reasons why we are interested in biofuels:To reduce our dependence on fossil fuelsTo reduce reliance on foreign oilTo lower emission of green house gasesTo bring business to rural economics

ADVANTAGES OF BIO FUELS

1. There is no emission of hazardous gases2. Locally available in every region of the

world.3. Friendly with the environment, so they do

not cause global warming4. The energy release per unit mass of

biofuel is greater than the energy

TWO METHODS TO FORM BIOFUEL;

A. SUGAR CROPS AND STARCH ARE GROWN AND THROUGH PROCESS OF FERMANTATION, EHANOL IS PRODUCED.

B. PLANTS ARE GROWN NATHURALLY TO PRODUCE OIL LIKE ALGAE.

OIL ARE HEATED TO REDUCE VISCOSITY, THEN DIRECTLY USE AS FUEL FOR DIESEL ENGINES.

THEY CAN BE DIVIDED INTO THREE CATEGORIES

First generation biofuel

Made from sugar , starch, and

vegetable oil

Second generation bio fuel

Made from non-edible plant materials.

Third generatio

n Bio fuel

Made from algae and microbes

FIRST GENERATION

Biodiesel

Biogas

SyngasBio

alcohols

Vegetable oil

APPLICATION OF BIODIESEL

Car diesel engine Effective solvent Oxygenated fuel

ADVANTAGE OF BIODIESEL

Biodiesel can be termed clean fuel as it does not contain carcinogens and its sulphur content is also lesser than the mineral diesel.

It possesses high biodegradability and lubricating property.

Improves engine efficiency and operating life cycle.

Domestic resourceGreatly reduces particulate matter and

carbon monoxide emission

DISADVANTAGES OF BIODIESEL

Higher production cost.Biodiesel is more likely than petroleum diesel to attract moisture.

Poor low temperature.

BIOALCOHOL

Biologically produced alcohol , most

Commonly ethanol, and lessCommonly propanol and butanol.

APPLICATION OF BIO-ETHANOL

Petrol engine as a replacement for gasoline

Fire placesFuel for vehiclesEthanol fuel is the most commonly used bio-fuel in the world.

VEGETABLE OIL

Generally used for cooking purpose.

It is used in several old diesel engine that have indirect injection system.

Vegetable oil is mainly used for the production of biodiesel.

BIO GASBiogas is mainly produced after the anaerobic digestion of the organic materials.

Biogas produced is very rich in methane.

APPLICATION OF BIOGAS

To produce electricityCooking purpose To heat the digester Space heatingWater heatingProcess heating

CONCLUSION

BIOFUEL PODUCTION HAS LEAD TO:oRural electrificationoImproving agricultureoJob creationoPower to local community
