The Potential of Waste Cooking Oil B20 Biodiesel Fuel with Lemon Essential Oil Bioadditive: Physicochemical Properties, Molecular Bonding, and Fuel Consumption

This study is motivated by the depletion of fossil fuels in nature, which inversely proportional to higher level fuel oil consumption, so need for alternative fuels, namely biodiesel. Biodiesel can be made using waste cooking because its abundant quantity, low price, and not being reused. One efforts achieve energy conservation improve quality bioadditives. A lemon essential used as a bio-additive it easily soluble oxygen-rich content reduce rate consumption. The process this produce biodiesel with (WCO) transesterification process. samples containing bioadditive on B20 varying volume fraction (0%; 0.1%; 0.15%; 0.2%). In general, research done three steps. first step characterization compound composition (GCMS) functional group (FTIR) diesel fuel, biodiesel, bioadditive. second physicochemical properties (density, viscosity, flash point, calorific value) various concentrations bioadditive, then compared SNI 7182:2015. third determining consumption engines. results show that 2% has high ability Copyright © 2021 Authors, Published BCREC Group. an open access article under CC BY-SA License (https://creativecommons.org/licenses/by-sa/4.0).
