    vegetable oils used for biodiesel are mainlyRapeseed or Sunflower oil in Europe, the USA andCanada uses Soyabean, Rapeseed, other waste oilsand fats; frying oil and animal fat is the chosenoption in Ireland; Castor oil and Soyabean oil isused in Brazil; Coconut oil is preferred in Malaysia

    and Philippines; Palm oil in Thailand, Malaysia,Indonesia and the Philippines; Cotton Seed oil inGreece; Linseed and Olive oil in Spain; Jatrophaand Karanja in used in India, Nicaragua and Africato produce biodiesel (Frank et al., 2009; Altin etal., 2001, Arjun et al., 2008). Several other non-edible plants such as Neem ( Azadirachta Indica),Meswak (Salvadora Species), Mahua (Madhucaindica), Rubber (Hevea Species), Castor (Ricinuscommunis), Diploknema Butracea, Garcinia Speciesand Thumba (Citrullus colocynthis) can also beused for producing biofuels in India (Barnwal and

    Sharma, 2005; Mohibbe et al., 2005; Augustus etal., 2003).

    1.3 Biodiesel as Fuel for Diesel Engines:Biodiesel, the renewable liquid fuel produced frombiological raw material is a good substitute forpetroleum diesel. Biodiesel contains no petroleum,but it can be blended at any level with petroleumdiesel to create a biodiesel blend. It can be used incompression ignition engines with little or nomodifications. As an alternative fuel, biodiesel canprovide almost same power output as of diesel

    (Gumus and Kasifoglu, 2010; Zafer and Mevlut,2008; Christian et al., 2009, Pall et al., 2009). Theconversion process of vegetable oil into biodieselis quite efficient, in nearly one-to-one ratio.Among the many advantages of biodiesel fuelwhich includes its safe use in all conventionaldiesel engines, offers almost the sameperformance and engine durability as conventionaldiesel fuel, non-toxic and reduces tailpipeemissions, visible black smoke and noxious fumesand odours and higher cetane number whichimprove the combustion characteristics. However

    NOX emission of biodiesel increases because ofrapid combustion and other fuel characteristics.Diesel fuel blends with biodiesel have superiorlubricating properties with reduced wear and tearon the diesel engine components. The mostcommon diesel fuel blends are B10 containing 10percent biodiesel and B20 containing 20 percentbiodiesel (Sirisomboon et al., 2007; Nag et al.,1995).

    Lot of research work is being done to analyse theengine combustion and performance using straight

    vegetable oils as well as biodiesel but fewerresearchers have analysed and compiled the

    economics of biodiesel, its formulation techniquesand fuel related properties in recent past. In thispaper, a detail survey of literature is thereforeundertaken to comprehensively review thedifferent recently published research papers oneconomical viability, conversion of straight

    vegetable oil into biodiesel and combustion relatedproperties of biodiesel fuel for their utilization indiesel engines.

    2.0 Economics of Biodiesel:Economical feasibility of biodiesel depends on theprice of the crude petroleum and the cost oftransporting diesel through long distances. It iscertain that the cost of crude petroleum is boundto increase due to increase in its intensivedemand, limited supply, strict regulations on thearomatics and sulphur contents in diesel fuels

    which will result in higher cost of production ofdiesel fuels as removal of aromatics from thedistillate fractions requires capital-intensiveprocessing equipments. The major economicfactor to consider for input costs of biodieselproduction is the feedstock (price of seed, seedcollection and oil extraction, transport of seed andoil), which is about 7580% of the total operatingcost. Other important cost related factors arelabour, methanol and catalyst for biodieselconversion for straight vegetable oil, which mustbe added to the feedstock. Cost recovery will be

    through sale of oil cake and of glycerol (Mulugetta,2009). The volatile oil prices due to increaseddemand have necessitated for continuous researchand development into the biodiesel sector so as toincrease the production of biodiesel of suitablequality and at reasonable price so that it cancompete with diesel fuel. Between 2001 and 2006alone, the global annual production of biodieselgrew up by 43% (Victor et al., 2010).

    India has rich and abundant forest resources witha wide range of plants and oilseeds. The

    production of these oilseeds can be stepped upmany folds for producing diesel fuels. Economicalfeasibility of biodiesel depends on the price of thecrude petroleum and the cost of transportingdiesel to long distances to remote markets in India.Further, the strict regulations on the aromaticsand sulphur contents in diesel fuels will result inhigher cost of production of conventional dieselfuels. The reason for high biodiesel prices are thelimited availability of biodiesel feedstocks. Thebiodiesel program in any country has a time lagbetween policy planning and actual

    implementation and hence the introduction couldbe gradual, gaining the maturity only after 4-5

    3.1 Heating/ Pyrolysis:

    Heating/ Pyrolysis is the process in which highmolecular weight compound breaks in to smallercompounds by means of heat with or withoutcatalyst. Pyrolysis refers to a chemical changecaused by the application of heat energy in theabsence of air or oxygen. The liquid fractions ofthe thermally decomposed vegetable oils are likelyto get converted into liquid oils. Many

    investigators have studied the Pyrolysis oftriglycerides to obtain products suitable for dieselengines (Babu, 2008; Bridgwater, 2003). ThePyrolyzate oils have almost same viscosity, flashpoint, and pour point compared to diesel fuel withequivalent calorific value. The cetane number ofthe Pyrolyzate oil has been found to be lower. ThePyrolyzate oils from vegetable oils containacceptable sulphur content, water and sedimentand give acceptable copper corrosion values butunacceptable ash and carbon residue. Mechanismsfor the thermal decomposition of triglycerides are

    likely to be complex because of many structuresand multiplicity of possible reactions of mixedtriglycerides (Manurung et al., 2009).

    3.2 Dilution/ Blending:

    High viscosity fuels like vegetable oils can be mixedwith low viscosity fuel like diesel to overcomeoverall viscosity. These blends can then be used asdiesel engine fuels. Dilution of vegetable oils canbe accomplished with a solvent, methanol orethanol. Vegetable oil can be directly mixed withdiesel and may be used to run diesel engines.

    Blending of vegetable oil with diesel have beenexperimented successfully by many researchers.

    The dilution of Sunflower oil with diesel fuels inthe ratio of 1:3 by volume has been studied andengine tests were carried out by Ziejewski et al.(1983). They concluded that the blend could notbe recommended for long term use in the directinjection diesel engines due to density difference.

    Pryor et al. (1983) had conducted the short term

    and long term performance tests with blends ofvegetable oil with diesel. In short termperformance test, crude-degummed Soybean oiland Soybean ethyl ester were found suitablesubstitutes for diesel fuel. A longer termevaluation of the engine when using 100% crudesoybean oil was prematurely terminated severeinjector chock led to decreases in power outputand thermal efficiency. Parmanik (2003) studiedthe properties and use of Jatropha oil and dieselfuel blends in compression ignition engine. Theheating value of the vegetable oil was comparable

    with ordinary diesel fuel and cetane number wasslightly lower than diesel oil. He also studied theeffect of blending Jatropha oil with diesel fuel incompression ignition engines. Significantimprovement in engine performance was observedas compared to pure vegetable oil. The exhaust gastemperature was reduced due to reduced viscosityof the vegetable oil diesel blends. It was found thatthe fuel consumption was increase with a higherproportion of the Jatropha oil in the blends.Acceptable thermal efficiencies of the engine wereobtained with blends containing up to 50% (by

    volume) of Jatropha oil.

    biodiesel production by lipase catalyst. The timetaken to get the 67 % yield of biodiesel was 72hours at room temperature. However, the energyinput was zero. The reaction time and the cost oflipase were hurdles to commercialize lipaseprocesses.

    4. Properties of Biodiesel:Biodiesel is a better fuel than diesel fuel in termsof sulphur content, flash point, and aromaticcontent. The fuel characteristics of biodiesel areclose to diesel fuels, and therefore biodiesel

    becomes a strong alternative to replace the dieselfuels (Demirbas, 2009). The conversion oftriglycerides into methyl or ethyl esters throughthe transesterifcation process reduces themolecular weight to one-third that of thetriglyceride reduces the viscosity by a factor ofabout eight and increases the volatility marginally.Biodiesel has viscosity close to diesel fuels. Theseesters contain 10 to 11% oxygen by weight, whichmay improve combustion as compared tohydrocarbon based diesel fuels in an engine (Ejazand Younis, 2008). The cetane number of

    biodiesel is around 50 which are higher thandiesel. The use of tertiary fatty amines and amidescan be effective in enhancing the ignition qualityof the diesel fuel without having any negativeeffect on its cold flow properties. Since thevolatility increases marginally, the startingproblem persists in cold conditions. Biodiesel haslower volumetric heating values (about 12%) thandiesel fuels but has a high cetane number andflash point (Sylvain et al., 2009; Achten et al.,2008; Houfang et al., 2009) Some of the desirablefuel properties of biodiesel derived from differentvegetable oils are presented in Table 2.5.

    5.0 Conclusions:Many energy fuels are being recently investigatedas potential substitutes for the current high-pollutant diesel fuel derived from diminishingcommercial sources. In the past 15 years, biodiesel

    has progressed from the research stage to a full-production scale in many developed countries.Vegetable oil either from seasonal plant crops orfrom perennial forest trees origin, after beingformulated, have been found suitable forutilization in diesel engines. Many traditional seedoils like Pongamia Glabra, Jatropha (JatrophaCurcas), Mallous Philippines, Garcinia Indica,Thumba, Karanja and Madhuca Indica etc. areavailable in the country, which can be exploited forbiodiesel production purposes. Although biodieseloffers several advantages, including technical,

    environmental, and socio-economic, it has somedisadvantages. Major disadvantages of biodieselare higher viscosity, lower energy content, highercloud point and pour point, marginal increase innitrogen oxides (NOX) emissions, lower enginespeed and power, engine oil degradation, injectorcoking, engine compatibility, high price ofbiodiesel and higher engine wear. Importantoperating disadvantages of biodiesel incomparison with petro-diesel are cold startproblems, the lower energy content, higher copperstrip corrosion and fuel pumping difficulty. Someof the salient conclusions are drawn on the basisof available literature for economics of bio-diesel,

    its formulation techniques and combustion relatedproperties:1.The costs for biodiesel production from palm oil,

    soybean oil and Jatropha oil are estimated aboutRs 45.0 /litre, Rs. 44.0/litre and Rs 39.0 /litre,respectively.

    2.The major economic factor to consider for inputcosts of biodiesel production is the feedstock(price of seed, seed collection and oil extraction,transport of seed and oil), which is about 75-80% of the total operating cost.

    3.Other important cost related factors are labor,methanol and catalyst for biodiesel conversionfor straight vegetable oil, which must be addedto the feedstock. Cost recovery will be throughsale of oil, cake and of glycerol.

    4.Mechanisms for the thermal decomposition(Pyrolysis) of for biodiesel production are likely

    to be complex because of many structures andmultiplicity of possible reactions of mixedtriglycerides.

    5.Direct blending of vegetable oil with diesel couldnot be recommended for long term use in thedirect injection diesel engines due to densitydifference.

    6.A micro-emulsion of methanol with vegetableoils can perform nearly as well as diesel fuels.

    7.Transesterification of vegetable oils provides asignificant reduction in viscosity, therebyenhancing the physical and chemical properties

    of vegetable oil to improve the engineperformance.

    8.The fuel properties of biodiesel are close todiesel fuels, and therefore biodiesel becomes astrong alternative to replace the diesel fuel.
