Biodiesel

  1. 1. Table of contents Introduction to biodiesel Applications of biodiesel Advantages & disadvantages of biodiesel Sources of biodiesel Future of biodiesel Case study on Iran Conclusions
  2. 2. Introduction to biodiesel HistoryRudolf diesel was the inverter of biodiesel, estimated 100 years ago. It was developed in the year 1890s. What is biodiesel? Biodiesel is made up of monoalkyl esters of long chain fatty acids that come from vegetable oil or animal fats. After which, the feedstock is converted by trans- esterification, into biodiesel.
  3. 3. Biodiesel is replacement for petroleum diesel fuel. It can be blended with petroleum diesel fuel in any proportion.Biodiesel can be used 100% (B100) or in blends with petroleum diesel fuel. Blends are indicated by B##, which correspond to the percentage of biodiesel in the blended fuel.
  4. 4. Applications of biodiesel Biodiesel has a wide variety of application in all the fields where fuel is used. To add on, it added advantages of efficiency improvement.Examples includes:Motorbikes, Airplanes, Mass transit (trains, buses)Trucks & heavy equipment , Electrical generatorsFarm equipments, Marine uses ,Biodiesel as lubricant & solvent
  5. 5. Biodiesel as lubricant and solvent• Potential markets for biodiesel extend beyond the transportation and electrical-generation sectors. Biodiesel can be used straight as a machinery lubricant. Biodiesel’s solvent properties may be used to clean dirty or greasy engine or other machine parts.
  6. 6. Marine usesBiodiesel is an ideal choice for the use in marine applications. Biodiesel have more environmental benefits. Biodiesel is “user-friendly” Biodiesel can work in several marine factions.
  7. 7. Advantages of Biodiesel Renewable energy source Can distribute through existing diesel fuel pumps Less polluting Can use in existing oil heating systems and Extends life of catalytic diesel engines converters & engines Can be mixed withUtilizes excess production of petroleum diesel at any soybeans for manufacture concentration and time
  8. 8. Disadvantages of Biodiesel More expensiveCould harm rubber hoses in engines Requires energy to:Produce biodiesel from soy crops & sow, fertilize and harvest Requires frequent filter changingRequires improvement in distribution infrastructure
  9. 9. Sources of biodiesel• Algal Biodiesel• Fungus• Used coffee grounds• Exotic resources
  10. 10. Algal BiodieselUtilizing algae that contains natural oil content>50% Can be grown on algae ponds at wastewater treatment plants Extracted from the systemand processed into biodieselDoes not entail a decrease in food production
  11. 11. Fungus Utilizing single-cell fungi that contains lipids .E.g.Cunninghamella japonicaExtracted from the cell and turned into Biodiesel Recent discovery of a variant of fungus Gliocladium roseum production of ‘myco-diesel’ (medium length hydrocarbons) from celluloseDiscovered in the rainforests of northern Patagonia
  12. 12. Used coffee grounds Utilising used coffee grounds that contains oil content 10-15% Extracted and underwent conventional processing into Biodiesel
  13. 13. Exotic resourcesUtilizing alligator fat which is aprimary waste product• cheaper to refine Biodiesel produced is similar in composition to biodiesel created from soybeans
  14. 14. Future of BiodieselGeneticallyEngineeredMicroalgae
  15. 15. Microalgae Its species are rich in oil Abundant; almost in every ecosystemCO2+ sunlight -> oxygen + biomass• Produce almost half of the atmospheric oxygen
  16. 16. Microalgae BiodieselUnder optimized condition, can produce up to 90% oil of dry weightPotential production of oil higher than oil crops• Use little land resource w/o causing potential biomass deficit Can grow in extreme environmentCultivated only by using seawater, CO2 and sunlight

  20. 20. Microalgae Genetic Engineering • Optimization for enhanced biofuel production • Improve accumulation ofWhy? targeted bioenergy carriers • Quantity & quality of biodiesel linked as to how lipid metabolism is controlled Solution Manipulate the biology of microalgae cells to allow for secretion of lipids
  21. 21. Case Study: Future of Bioenergy in Iran Extensive use & export of Iran’s crude oil and natural gas will be limited in the future. Thus renewable liquid fuels will be heavily needed to eventually totally replace petroleum- derived transport fuels which in addition, contributes to the emission of greenhouse gasesSalt lake “Urmia” which have given rise to new species of algae for biofuel
  22. 22. Case Study: Solution for Biodiesel Production Overcoming the challenge, two options • Managing the agriculture residues & energy production like bioethanol and biogas • Investing on non-food crops e.g. microalgae Due to climate & • Looking at this table, microalgae come geographical problems views itself as the only source that has • Only 12% of total land the potential to completely replace area can be use for crop growing thus depending petroleum-derived diesel on energy crops not • Therefore, microalgae genetic feasible engineering would help to visualize more the economic production of biodiesel in Iran
  23. 23. Case Study: Project on microalgae Researches at Teheran’s Shiraz University carried a biofuel project Microalgae were isolated during a screening program from soil & water • samples are collected from the paddy fields of Fars province and the Maharlu Salt Lake Has succeeded in producing green fuel from the algae Chlamydomonas The researchers registered their findings at the National Center for Biotechnology Information (NCBI)which is based in the USA
  24. 24. Case Study: Having potential of using microalgae genetic engineering Iran has a good potential and possibilities due to: Presence of saline lakes in Iran, containing various Good capacity building species of microalgae Establishing microalgae culture ponds in different Gained experiences in plant genetic areas of Iran engineering within the last decade • Unlimited access to saline waters and sunlight Strong government support • Based on the law, production and Presence of highly efficient release of transgenic organisms are genetic engineering free in Iran provided that they pass all technologies in the world the biosafety requirements imposed by Iran’s National Biosafety Law (INBL)
  25. 25. ConclusionsMicroalgae genetic engineeringhave a very promising role in thefuture as it has great potentials forbiofuel production.
