Biodiesel-an alternative fuel
Biodiesel is an alternative fuel that can be used in diesel engines. It is made through a chemical process called transesterification that uses triglycerides from vegetable oils and fats. Biodiesel has advantages over petroleum diesel like reduced emissions and biodegradability. However, it also has disadvantages like lower energy content and issues with operating in cold weather. Producing enough biodiesel to replace petroleum diesel at a large scale presents economic and logistical challenges.
Production of biodiesel from vegetable oils
Biodiesel is produced by transesterification of
triglycérides present in animal fat or vegetable oils, by
displacing glycerine with a low molar mass atcobol. This
resulting ester mixture has physico-chemical properties
similar to those of petroleum diesel.
This paper reviews the synthetic paths that lead to
biodiesel by means of the catalytic transesterification of
vegetable oils. Although methyl esters are at present the only
ones produced at industrial scale, the use of ethanol, which
can also be obtained from renewable resources, has been
considered, since it would generate a cleaner and more
biocompatible fuel.

Biodiesel
Biodiesel is an alternative fuel made from renewable sources like vegetable oils and animal fats through a process called transesterification. It has similar chemical structure to diesel, but with an ester group. Biodiesel has a carbon neutral footprint since it uses carbon absorbed by plants, while diesel increases carbon dioxide levels over time. Producing and using biodiesel helps reduce pollution from sulfur dioxide and greenhouse gas emissions compared to conventional diesel. However, biodiesel may gel more easily in cold weather and increase demand for cropland.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

- 1. www.studymafia.org Submitted To: Submitted By: www.studymafia.org www.studymafia.org Seminar On Biodiesel
- 2. Content Introduction What is Biodiesel? Benefits of Biodiesel Environmental Issues Problems brought by Biodiesel Biodiesel Samples Biodiesel Background The Future of Biodiesel Conclusion References
- 3. Introduction Biodiesel can be operated in any diesel engine with little or no impact to the fuel system. Biodiesel has a solvent effect which may release deposits accumulated on tank walls and pipes from previous diesel fuel storage. The release of deposits may clog filters. Biodiesel can be used as a pure fuel or blended with petroleum in any ratio.
- 4. What is Biodiesel? Alternative fuel for diesel engines Made from vegetable oil or animal fat Meets health effect testing (CAA) Lower emissions, High flash point (>300F), Safer Biodegradable, Essentially non-toxic. Chemically, biodiesel molecules are mono-alkyl esters produced usually from triglyceride esters Fatty Acid Alcohol Glycerin Vegetable Oil Biodiesel FA FA FA FA
- 5. Biodiesel can be used in existing Diesel Engines Pure Biodiesel (B100) or blended with petroleum diesel (B20, BXX). Rudolf Diesel: peanut oil. Little or no engine modifications Use existing fuel distribution network. Available now
- 6. Benefits of Biodiesel - High cetane number (average 45,8-56,9 units) - High flash point (above +100) - Good lubricating property - Absence of sulfur and aromatic hydrocarbons - Low toxicity of emissions - Virtually complete biodegradability (99% biodiesel are destroyed in water or soil for 28 days) - Zero balance of greenhouse gases 6
- 7. Environmental Issues Burning fossil fuels increases atmospheric levels of carbon dioxide Fossil fuels are a finite resource 30% Increase Graph taken from USF Oceanography webpage
- 8. Problems brought by Biodiesel • Certain biodiesel gels easily under cold temperature • Deforestation for plantation • Degrades rubber in old cars • Synthetic rubbers that are resistant
- 10. Biodiesel Challenges Cold Weather Operation (Chemistry) Producing enough feedstock oil to replace a large portion of petroleum (biology, chemistry, physics, economics) Engine and emissions optimization (chemistry, physics)
- 11. Biodiesel Background Four main production methods Direct use and blending Micro emulsions Thermal cracking Transesterification Transesterification Most common production method Uses vegetable oils and animal fats as feed stocks The reaction of a fat or oil with an alcohol to form esters (biodiesel) and glycerol
- 12. The Future of Biodiesel Should be considered for use as an alternative and not a primary fuel Short and long term environmental benefits will be worthwhile Storage Issues with Stability and Transportation issues with high cost of delivered fuel compared to fossil fuels Fuel-supply reliability Lack of understanding of environmental impact - NOx emissions Complexity of biomass-power infrastructure compared to known well established coal and natural gas markets
- 13. Conclusion Biodiesel is eco-friendly. Biodiesel is clean burning alternative fuel. Biodiesel contain no petroleum, but can be blended with conventional diesel fuel. These fuel can be used in any diesel engine without any modification. Biodiesel is degradable , non toxic and free from sulphur and lead.
