Comparison of Physicochemical Properties of Simarouba Glauca, Dairy Scum and Karanja Biodiesel of Various Blends with Diesel

摘要

Day by day depletion of liquid fossil fuels creates necessity to find out an alternative liquid fuel like biodiesel. Rapid growth in transportation, industrialization and civilization from time to time causes increase in requirement of fuel and energy. This paper deals with the production of biodiesel from Simarouba Glauca, Dairy scum and Karanja oil by transesterification process using calcium oxide as a heterogeneous catalyst and methanol as the alcohol. Biodiesels are blended with diesel in different proportions and tested the physicochemical properties such as viscosity, flash point and density for each blended biodiesel. The important properties of biodiesel such as cloud point, pour point, ash content and carbon residue are tested and compared with other biodiesels.
