Abstract

Over consumption of fossil fuels turns the world’s pivot in to finding of a new possible substitute fuels. In this category, biodiesel get major attention as an alternative fuels. Production of biodiesel are dependent on various feedstock sources like algae, vegetable oil, food waste, animal fat, fatty acids containing seeds and grease etc. In the present study soybean seed oil and its methyl ester have been taken to find out their possibility as petroleum-diesel fuels. Experimental analysis has been made to detect the physico-chemical properties of soybean seed oil. Biodiesel were produced through transesterification reaction from soybean seeds oil. In transesterification process about 90 % yield of biodiesel were produced. The obtained biodiesel was characterized as an alternative diesel fuel through series of ASTM and BIS. Higher specific gravity, flash point, fire point, iodine point, pour point and cloud point were obtained and comparison has been carried out to petroleum diesel. GC-MS analysis of the esters of fatty acids shows that the overall percentage of methyl ester is more than the ethyl ester.
