Among the processes of algae conversion technology, three main routes to produce liquid biofuels from algae are biodiesel via the extraction or transesterification, bio-oil via pyrolysis, and bio-oil via HTL. Both thermochemical conversion pyrolysis and HTL technology are …

This paper presents a case study on biofuels production from microalgae cultivated in municipal wastewater in Gothenburg, Sweden. A) Combined biodiesel

As its name implies, algae are grown on open ponds in this difference between biodiesel production from vegetable sources and algae. Algae were promising organisms for providing both novel biolog ically active substances and essential compounds for human nutrition (Mayer and Hamann, 2004 ). Therefore, an increasing supply for algal extracts, fractions or pure compounds for the economical sector was needed to biodiesel production, algae can be also used as feedstock to produce different valuable products such as fertilizer, energy, neutraceuticals, protein, animal feed etc. The other signifi‐ cant property is that microalgae can remove some heavy metals, phosphorous, and nitrogen from water during its growth. Algae also clean up the water.

Algae biodiesel production

Experts estimate it will take 140 billion gallons of algae biodiesel to replace petroleum-based products each year. Biodiesel Fuel Production from Algae as Renewable Energy A.B.M. Sharif Hossain, Aishah Salleh, Amru Nasrulhaq Boyce, Partha chowdhury and Mohd Naqiuddin Biotecnology Laboratory, Institute of Biological Sciences, Faculty of Science, University of Malaya, Kuala Lumpur 50603, Malaysia Abstract: Biodiesel is biodegradable, less CO 2 and NO x emissions Algae is the vehicle to convert carbon dioxide to biomass using solar energy, and transesterification converts the crude oil to the organic biodiesel fuel. This is the ultimate in carbon dioxide sequestration because it so rapidly consumes carbon dioxide to create large quantities of biomass. The production of algae to harvest oil for biodiesel has not yet been undertaken on a commercial scale, but feasibility studies have been conducted to arrive at the above yield estimate.

Oct 16, 2011 Processing of biodiesel from algae biomass has attracted much interest in recent times due to many reasons. Significant amongst them are

oil extraction and transesterification. It was noted that the maximum amount of oil was extracted from algal biomass using combination of n-hexane and Di-ethyl Ether.

May 31, 2009 Inevitably, there are going to be energy inputs that are necessary to produce a fuel from algae, just as there are for other biofuels, such as corn

“According to industry data, a ﬁve-million gallon per year biodiesel conversion plant (14,000 gallons per day) would have cost approximately $6,500,000 in 2005 or about $7,300,000 in 2009 dollars.” Algenol has an algae strain that can produce ethanol directly, and the system can then convert remaining biomass into hydrocarbon fuels such as biodiesel, gasoline, and jet fuel. In this chapter, algae production methods that cover the algae strain and location selection, algae cultivation, harvesting, oil extraction, and algal biodiesel production processes are presented in detail with alternatives.

Biodiesel is used in diesel engines, and is thus different from the waste and vegetable oils used to fuel converted diesel engines.

One of the main points of friction in the lipid extraction component of algal biofuel production is the need to remove all moisture from the algae in advance, leaving a dry powder from which the lipids can be separated. Noticing that some algae have very high oil content, the project shifted its focus to growing algae for another purpose – producing biodiesel. Some species of algae are ideally suited to biodiesel production due to their high oil content (some well over 50% oil), and extremely fast growth rates. Biodiesel production from Algae is emerged as the promising alternative fuel, technically and environmentally acceptable and easily available.

Microalgae can provide several different types of renewable biofuels. These include methane produced by anaerobic digestion of the algal biomass[6] biodiesel.

Different species such as tribonema, ulothrix and euglena have good potential for biodiesel production. Gene technology can be used to enhance the production of oil and biodiesel contents and stability of algae. Algal Biomass and Biodiesel Production Emad A. Shalaby Biochemistry Dept., Facult. Of Agriculture, Cairo University Egypt 1. Introduction Biodiesel has become more attractive recently because of its environmental benefits and the fact that it is made from renewable resources. The cost of biodiesel, however, is the main Biodiesel is a diesel fuel derived from animal or plant lipids (oils and fats). Studies have shown that some species of algae can produce 60% or more of their dry weight in the form of oil.
