Abstract:

In this study, biodiesel was synthesized from Waste Cooking Oil (WCO) by one-step method, trans esterification of WCO. The raw oil containing 0.253%Free Fatty Acid ( FFA ) , 0.526(mg KOH / g) acid value, 9 ံC cloud point and 0.91g/ml density. WCO was collected from local ----- shop. In the trans esterification reaction method, NaOH was used due to low FFA content in WCO. Various reaction parameters such as oil to methanol volume ratio and catalyst concentration were optimized. The reaction time, reaction temperature and stirring rate were two hours , 60 ံC and 250 rpm respectively. Finally various properties of biodiesel such as FFA, kinematic viscosity, specific gravity ,moisture cntent, cetane index, pour point, flesh point , cloud point, saponification value, iodine value and yield % of optimized biodiesel were measured and compared with petro- diesel standard. The yield of biodiesel was 90%.The fuel consumption of produced biodiesel was tested with 20hp single cylinder diesel engine by blending with prtro-diesel in the ratio of 1:4 ,1:1, 4;1 and compared fuel consumption of with petro – diesel only.
