8. Bio fuel from Algae

9. # Algae
• Micro organisms or plantlike biological
organisms that use sunlight to photosynthesize
and transform the carbon dioxide into energy
in a very efficient manner. Algae produce oil as
a part of photosynthesis

10. #Bio fuel
• plant fuel or algal fuel is an alternative to fossil
fuel that uses algae as its source of natural
deposits. Several companies and government
agencies are funding efforts to reduce capital
and operating costs and make algae fuel
production commercially viable.

11. #fuels
• Algae can be converted into various types of
fuel, depending on the technique and the part
of the cells used.
*lipids
bio diesel
*Carbohydrates
bio ethanol &bio _
butanol

12. Other Fuels
• Bio gasoline
• Methane
• Ethanol
• Jet fuel

13. Bio fuel
Advantages:-
• Renewable sources
• Better for environment
• Better for air quality
Dis advantage:-
• Use lot of water
• Threaten food supply
• Cost
• Global warming or

15. *Bio diesel:
Biodiesel fuel is essentially petroleum sources, from
animal or plant lipids (oils and fats).
* The U.S. Department of Energy's Aquatic Species
Program,, focused on biodiesel from microalgae. The final
report suggested that biodiesel could be the only viable method
by which to produce enough fuel to replace current world diesel
usage.

16. Biofuel Fossil Fuel Differences
Ethanol Gasoline/Ethane
Ethanol has about half the energy per mass of gasoline, which means it takes
twice as much ethanol to get the same energy. Ethanol burns cleaner than
gasoline, however, producing less carbon monoxide. However, ethanol
produces more ozone than gasoline and contributes substantially to smog.
Engines must be modified to run on ethanol.
Biodiesel Diesel
Has only slightly less energy than regular diesel. It is more corrosive to engine
parts than standard diesel, which means engines have to be designed to take
biodiesel. It burns cleaner than diesel, producing less particulate and fewer
sulfur compounds.
Methanol Methane
Methanol has about one third to one half as much energy as methane.
Methanol is a liquid and easy to transport whereas methane is a gas that must
be compressed for transportation.
Biobutanol Gasoline/Butane
Biobutanol has slightly less energy than gasoline, but can run in any car that
uses gasoline without the need for modification to engine components.

20. Bio fuel production

21. 1#selection
Decide which type of algae you want to grow.
Different species of algae contain different
levels of oil. Algae *scum or *seaweed are
best suited for production of biofuel.

22. • Grow the organism in optimal
conditions
*sun light
*water
*carbon dioxide
*pH 7-9
• Take advantage of a photo bioreactor
if the light conditions are not
favorable in your area
• Growing algae close to energy
manufacturing plants, which produce
carbon dioxide, often facilitates the
process.
2#cultivation

26. 3#Harvesting
• Use gloves to cover your hands when you are
harvesting the algae.

27. 4#Extraction
a_
Utilize any variation of specially-designed press,
which extracts the oil from the walls of the
algae cells, similar to those used to extract oil
from olives
b_
A chemical process is also applied to extract oil as
well.

28. c_
Dry the algae through a mechanical press.
d_
Mixing the pressed oil with hexane can extract
even more oil,
e_
filtering and cleaning ;
*Clean the oil using carbon dioxide as a supercritical
fluid. A combination of both methods is often used to
extract the oil

29. 5#Refining
• Refine the oil by using a catalyst to aid the
conversion into diesel
• Catalysts speed up reactions throughout the
process. The right catalyst can make a big
difference
