“…In order for vegetable oil to be feasible as fuel, it is necessary to reduce its viscosity close to that of diesel fuel. In addition to transesterification, some methods to reduce the viscosity of vegetable oils are dilution, microemulsion, pyrolysis and catalytic cracking [10,12].…”

Efforts to improve the physical and chemical properties of vegetable oils as diesel fuels such as viscosity and calorific value are indispensable with the depletion of fossil oil reserves. Jatropha oil with long chain fatty acids and high degree of unsaturation is mixed with short chain saturated fatty acid coconut oil in various compositions. The mixture was heated and stirred for 30 min at 90 • C. This mixing leads to a decrease in viscosity which allows for the breaking of the bond. The fatty acid molecule structure undergoes transformation that changes the degree of unsaturation and the average length of the carbon chain. Consequently, the kinematic viscosity and flash point of the mixture decreases while its calorific value increases.

“…In recent years, many initiatives for the production of oilseed-based biofuels (SVO or biodiesel) have emerged in West African countries, with the support of governments or through regional initiatives [20]. In this context, many perennial oil crops, especially Jatropha curcas, have been planted and large quantities of SVO are set to be produced in the coming years [21][22][23][24][25][26]. The most widespread scheme adopted by project promoters is the local production of oilseeds and their conversion into SVO by village-scale extraction units or decentralized cooperative mills, to fuel local stationary diesel engines [10,11,27].…”

Abstract. Biofuels based on vegetable oils offer the advantage being a sustainable and environmentally attractive alternative to conventional petroleum based fuel. The key issue in using vegetable oil-based fuels is oxidation stability, stoichiometric point, bio-fuel composition, antioxidants on the degradation and much oxygen with comparing to diesel gas oil. This provides a critical review of current understanding of main factor in storage method which affecting the biodiesel properties and characteristics. In the quest for fulfill the industry specifications standard; the fuel should be stored i n a clean, dry and dark environment. Water and sediment contamination are basically housekeeping issues for biodiesel. Degradation by oxidation yields products that may compromise fuel properties, impair fuel quality and engine performance. The effect of storage method on the fuel properties and burning process in biodiesel fuel combustion will strongly affects the exhaust emissions. IntroductionBurning fossil fuels such as coal, diesel and gas produces greenhouse gases give impacts on the environment. A range of greenhouse gases were produced when fossil fuels are burned, these gases include carbon dioxide, water vapour, methane and nitrous oxides. These gases trap the sun's heat in the atmosphere, it concentrate and increase the heat of the sun where it works quite similar to the lens in a magnifying glass. This is called the greenhouse effect.Studies have found that first-generation biofuels produced from current feedstock's using the most efficient systems and carbon releases results in emission reductions in the range of 20-60 per cent relative to fossil fuels. Generally, biofuels offer many priorities, including sustainability, reduction of greenhouse gas emissions, regional development, social structure and agriculture and securi-
