Biodiesel Production from Algae Oil

Algal oil is highly viscous, with viscosities ranging 10–20 times those of no. 2 Diesel fuel. The high viscosity is due to the large molecular mass and chemical structure of oils which in turn leads to problems in pumping, combustion and atomization in the injector systems of a diesel engine. Therefore, a reduction in viscosity is important to make high-viscous oil a suitable alternative fuel for diesel engines.

There are a number of ways to reduce vegetable oil's viscosity. These methods include; transestrification, pyrolysis (Pyrolysis Definition from AFR), micro Emulsion (Emulsions & Emulsification – from Wikipedia), blending and thermal depolymerization. One of the most common methods used to reduce oil viscosity in the Biodiesel industry is called transesterification. It involves chemical conversion of the oil into its corresponding fatty ester.

Other Methods of Producing Bio-diesel from Algal Oil

Other than transesterification, the other methods that have been considered to reduce the high viscosity of vegetable oils/algal oil are:

· dilution of 25 parts of plant/algal oil with 75 parts of diesel fuel

· microemulsions with short chain alcohols (e.g. Ethanol or methanol)

· thermal decomposition, which produces alkanes, alkenes, carboxylic acids and aromatic compounds

· catalytic cracking, which produces alkanes, cycloalkanes and alkylbenzenes

However, when compared with the above, the Transesterification process appears to be the best choice, as the physical characteristics of fatty acid esters (biodiesel) are very close to those of diesel fuel, and the process is relatively simple. Furthermore, the methyl or ethyl esters of fatty acids can be burned directly in unmodified diesel engines, with very low deposit
