A Comparative Study On Characterization Of Used Cooking Oil And Mustard Oil For Biodiesel Production: Engine Performance

Biodiesel is emerging as a promising substitute of an alternative fuel and has gained significant attention due to the predicted depletion of conventional fuels availability in near future and environmental pollution concern. Utilization of biodiesel produced from secondary feed stocks by tranesterification process is one of the most promising options to replace conventional fossil diesel fuel. In this research biodiesel is produced from used cooking oil and mustard oil by the process transesterificsation using KOH as a catalyst. The variables effecting the ester yield and characteristics of the biodiesel produced from both the oils were studied. The highest biodiesel yield of 92% was obtained with Used cooking oil under the conditions of 7:1 methanol to oil ratio, 60 degrees C temperature, 1.5 % KOH catalyst and 90 minutes reaction time. The quality of methyl ester is analyzed by using GC-MS and FTIR are compared. The blends of biodiesel (B20, B30) is used to investigate diesel engine (CI) performance with different loads at constant speed 1500 rpm. This study related Brake Thermal Efficiency (BTE) of UCO biodiesel blends showed similar trends where as the mustard biodiesel blends showed lower BTE when compared to that of conventional diesel. Hence it can be concluded that used cooking oil methyl ester is more efficient than mustard oil methyl ester. (C) 2018 Elsevier Ltd. All rights reserved.
