Outdoor artificial man-made ponds are used to cultivate a new batch of algae crops every few weeks.

How to produce biodiesel from algae. After separating the desired biofuel product or products from the microalgae biomass a significant portion of byproduct remains. That would give the industry the necessary time to produce a new generation of. The preference towards micro-algae is due largely to its less complex.

Biodiesel production from algae usually involves the conversion of lipids from algae through indirect transesterification in two steps 2-TE. All the power needed to produce the algae would come from biodiesel or from methane produced by the anaerobic digestion of biomass residue left after the oils had been extracted from the algae. Algae-based fuel is also superior to gas coal petrol and diesel because it is easy to cultivate.

Introduction Biodiesel has become more attractive recently because of its environmental benefits and the fact that it is made from renewable resources. The process of generating biofuel from algae involves the growth concentration separation and conversion of microalgae biomass some of which can be genetically altered. Because the cells grow in aqueous suspension where they have more efficient access to water CO.

Algal oil is converted into biodiesel through a transesterification process. Producing biodiesel requires an industrial alcohol such as methanol and a catalyst such as lye to convert the oil into a fatty acid methyl ester fuel. An excess of methanol is used to force the.

The cost of biodiesel however is the main hurdle to commercialization of the product. Alga Technologies grows algae in closed bioreactors to harvest astaxanthin in Israels Arava desert. The pilot scale plant is ready to use available feedstocks from new algae oil production partners so that REG can augment the pretreatment and production of algae biodiesel in continually increasing volumes as part of its continuous flow commercial-scale process technology.

The most effective way to extract the most oil from algae is by using a combination of manual and physical techniques. Research into algae for the mass-production of oil is mainly focused on micro-algae. In the short term a handful of early-stage companies working on algae want to produce Algae oils for biodiesel production replacing a significant proportion of the diesel fuel that currently serves about one-third of transport needs in the United States.
