Conventional energy sources that is petroleum fuel reserve are depleting day by day which has led the world to think about non-conventional fuels and other major concerning issue is about eco-friendly environment and it pull the search for ecofriendly renewable fuel. Biodiesel is non-toxic, biodegradable and contributes a minimal amount of net greenhouse gases. A study was conducted to produce biodiesel from sorghum oil by transesterification process. The volumetric ratio, catalyst type NaOH, KOH and concentration are some important parameters that affect the quality and yielding of biodiesel that also fulfil the ASTM D6751 standard. For yielding highest percentage (92.9) of biodiesel, the ideal condition were 5:1 molar ratio of sorghum oil to ethanol, 1.0% NaOH catalyst, reaction time 90 minutes, temperature 60C and 300 rpm stirring speed. While using 1.0% of NaOH and KOH as catalyst, higher amount of biodiesel was yielded in NaOH as comparing to KOH catalyst and biodiesel yielding were maximum in 1.0% NaOH catalyst as compared to 0.5% and 1.5% NaOH catalyst. At different parameters a minor difference in viscosity, acid value, and saponification value was observed. The detailed study has revealed that efficient biodiesel can be produced from sorghum oil under optimized conditions and appropriates catalyst concentration.
