Promising technologies for biodiesel production from algae growth systems.

摘要: Biodiesel is considered as a renewable fuel because it can be obtained from the transformation of vegetable oils, cooking greases or animal fats. Currently, oleaginous plants like rapeseed, sunflower, palm oil and soybean are most important sources biodiesel. However, productivity some these crops relatively low they require long extension lands. In this context, microalgae has been emerged source natural due to its lipids, starch hydrocarbon contents. Microalgae produces about ten times more than grown in systems open ponds photobioreactors. Open raceway well known have used grow algae for food, nutritional complements others. Their construction less expensive compared photobioreactors, but their lower. Photobioreactors found with different configurations (e.g. tubular, annular, plastic bags) numerous advantages over ponds: superieur control nutrients, light exposition carbon dioxide absorption, contamination avoidance other microorganisms. These culture receive special attention use flue gases nutrients wastewater perform growth. The common species literature experimental studies Chlorella sp., Spirulina sp.
