Algae Energy: Algae as a New Source of Biodiesel by Ayhan Demirbas

By Ayhan Demirbas

Climate swap, environmental influence and declining normal assets are using medical learn and novel technical strategies. Green strength and Technology serves as a publishing platform for medical and technological methods to "green" - i.e., environmentally pleasant and sustainable - applied sciences. whereas the main target lies on power and tool offer, the sequence additionally covers eco-friendly options in business engineering and engineering layout. Green power and Technology is a monograph sequence addressing researchers, complicated scholars and technical specialists, in addition to choice makers in and politics. the extent presentation levels from tutorial to hugely technical.

Algal oil could be a tremendous resource of biomass and algae’s skill to develop virtually anyplace has inspired scientists to additionally examine its power as a resource of biodiesel. Algae Energy covers the construction of algae tradition and using algal biomass conversion items. It additionally experiences sleek biomass-based transportation fuels, together with biodiesel, bio-oil, biomethane and biohydrogen.

Each bankruptcy opens with basic causes appropriate for people with a normal curiosity in algae strength and is going directly to offer in-depth clinical info for extra specialist readers. Algae strength is mentioned in the wider context of eco-friendly strength, with chapters protecting themes corresponding to:

• eco-friendly power facilities;

• algae technology;

• power from algae; and

• biodiesel from algae.

Algae Energy addresses the wishes of strength researchers, chemical engineers, gas and environmental engineers, postgraduate and complex undergraduate scholars, and others attracted to a realistic instrument for pursuing their curiosity in bio-energy.

Most biofuels in commercial production in Europe today are based on sugar beet, wheat, and rapeseed, which are converted into bioethanol/ETBE and biodiesel. 10 Availability of modern transportation fuels Fuel type Gasoline Bioethanol Biodiesel Compressed natural gas (CNG) Hydrogen for fuel cells Availability Current Future Excellent Moderate Moderate Excellent Poor Moderate-poor Excellent Excellent Moderate Excellent Ethanol has attracted considerable interest in both industry and research as a plausible renewable energy source in the future.

Bioethanol is by far the most widely used biofuel for transportation worldwide. Global bioethanol production more than doubled between 2000 and 2005. About 60% of global bioethanol production comes from sugar cane and 40% from other crops. Biodiesel refers to a diesel-equivalent mono-alkyl-ester-based oxygenated fuel. Biodiesel production using inedible vegetable oil, waste oil, and grease has become more attractive recently. The economic performance of a biodiesel plant can be determined once certain factors are identified, such as plant capacity, process technology, raw material cost, and chemical costs.

Engine tests were carried out at full load and at different speeds. The engine torque and power of cottonseed oil methyl ester were found to be lower than that of diesel fuel in the range of 3 to 9% and specific fuel consumption was higher than that of diesel fuel by approx. 8 to 10%. CO2 , CO, and NOx emissions of cottonseed methyl ester were lower than that of diesel fuel (Yucesu and Ilkilic 2006). In general, the physical and chemical properties and the performance of the cottonseed oil methyl ester were comparable to those of diesel fuel (Ilkilic and Yucesu 2008).
