Abstract

Biodiesel is the fuel obtained by transesterification of vegetable oil with lower viscosity than vegetable oil. There is lot of generation of Waste Cooking Oils (WCO). Utilization of this WCO leads to low production cost of biodiesel and reduces the disposal problems of waste cooking oils. In the present study, focus is on production of biodiesel using waste rice bran oil o as the raw material through transesterification process. The experimental conditions are selected as 59-60 C as reaction temperature and 300 rpm stirring speed during reaction. The highest yield of biodiesel, 92.02% was obtained at 6:1 mole ratio of alcohol to oil and 0.75% of catalyst concentration and reported as optimum conditions. The concentration of catalyst and mole ratio of alcohol to oil has substantial effect on properties of biodiesel such as flash point, fire point, density and kinematic viscosity. Gas chromatography and mass spectroscopy technique were used to analyze the fatty acid profile of biodiesel sample. The sample contains saturated, mono and poly unsaturated compounds.

Keywords
