EFFECT OF EXTRACTION METHODS ON FUEL PROPERTIES OF BIODIESEL AND MULTI-BLENDS FROM COCONUT AND .....

The demand for fossil fuels is expanding at an uncontrollable rate on a daily basis, resulting in significant levels of dangerous pollutants being released into the environment as a result of fuel burning. In that circumstance, an alternate fuel for diesel is required to reduce exhaust emissions while maintaining thermal efficiency. The impact of the extraction procedure on the fuel qualities of biodiesel and multi-blends was investigated in order to determine its viability as a long-term energy source feedstock. The saponification value (13.74, 3.51 mg KOH/g of oil), free fatty acid (11.86, 10.57), iodine value (0.18, 0.27 g I2/100g of oil), viscosity (0.45, 0.07 cSt), and density (0.86, 0.60 kg/m3) of the oil were all measured. The yields of oil and biodiesel from mechanically and solvently extracted coconut-peanut are (8.46 percent and 28.63 percent, respectively) (33.15 percent , 86.25 percent ). Mechanical extraction for biodiesel and coconut-peanut-diesel blends (B2.5, B5, B10, B15, B20, and B100) ranged from 1.73-5.9 mm2/s, 1.04-4.31 mm2/s for 40oC and 100oC viscosity; 1.8-9.2oC, cloud point; 0.6-8.4oC, pour point; 93.2-174, flash point; 99.2-174, fire point; 49 For 40oC and 100oC viscosity, solvent oil extraction varied from 1.7-4.45 mm2/s, 0.92-2.12 mm2/s; 1.3-5.7oC cloud point; 0.3-4.3oC pour point; 91.7-161, flash point; 97-168, fire point; 42.09-75.35 for cetane number. As the temperature rises, the density of fuel and multi-blends drops. The absorption intensity of OH and C=O in biodiesel components was determined using FTIR spectroscopy of coconut-peanut and blends. In most fuel characteristics, solvent extraction proven to be a superior and more promising technology for biodiesel synthesis than mechanical extraction. Using nanoparticle additions, however, the usability of coconut-peanut biodiesel and blends on engine cylinders can be increased.
