Transcript of Biodiesel from Algae

Biodiesel Made From Algae Biodiesel
Biodiesel is made from crops such as corn and soybeans for an alternative fuel. Algae Algae is grown like most plants, using photosynthesis. Photosynthesis is the process in which the algae converts the suns energy into chemical energy it can use to grow. A New Idea For Growing Algae A photobioreactor is used to harvest algae. They harvest one batch of algae at a time, and is set up with nutrients so that the algae can grow until harvested. Costs As of now, the fuel would be much too expensive to sell. It would cost around $30 a gallon. Government agencies are making efforts to reduce the operating costs to make it less expensive. After Algae is Harvested An oil press is used to extract the oil from the algae. It gets 75% of the oil out of the algae being pressed. The Oil After the oil is extracted, it's refined using fatty liquids. This process is called transesterification. Next, the mixture is refined to remove the glycerol. The final product is algae biodiesel fuel. The Chemical Process Catalyst is a substance that initiates or accelerates a chemical reaction without itself being affected. Photosynthesis Photosynthesis helps the algea grow and chemically change. In photosynthesis, light is the catalyst. Reactant A reactant is a substance that is present at the begining of a chemical reaction. Carbondioxide and water are the reactants in photosynthesis. 6CO2 + 12H2O + light > C6H12O6 + 6O2 + 6H2O
