Do biofuels from microalgae beat biofuels from terrestrial plants?

Energy in algal oil 37.90 Energy in biogas from residual biomass 50.00 Estimated as 22.85 MJ kg 1 of urea and 2.94 MJ kg 1 of diammonium phosphate. Using sedimentation followed by continuous vacuum belt filters. Approximate only in view of the developmental nature of algal oil recovery processes. Estimated as 80.4 MJ m 2 of facility area divided by a 20 year working life and the mass of oil pro...

Chemically synthesized biofuels from agricultural waste: Optimization operating parameters with surface response methodology (CCD)

Bioethanol is one of the most important alternative renewable energy sources that substitute the fossil fuels. Sugarcane bagasse has a content of cellulose and hemicelluloses, which make it suitable as fermentation substrate when hydrolyzed. The objective of work is ethanol production from sugarcane bagasse (SCB) by the fermentation process. Eight laboratory experiments were conducted to produc...

Biofuels from Algae

 Algae can provide a variety of fuels for transport, heating or electricity generation, including biodiesel, aviation fuel and biogas.  Algal biofuels are at an experimental stage and are more expensive than fossil fuels.  Algal biofuels could be made more costeffective by extracting other valuable products from algae or incorporating their production into waste water treatment.  Commercial...

Biofuels from microalgae.

Microalgae are a diverse group of prokaryotic and eukaryotic photosynthetic microorganisms that grow rapidly due to their simple structure. They can potentially be employed for the production of biofuels in an economically effective and environmentally sustainable manner. Microalgae have been investigated for the production of a number of different biofuels including biodiesel, bio-oil, bio-syn...
