Effect of synthetic and aromatic amine antioxidants on oxidation stability, performance, and emission analysis of waste cooking oil biodiesel

At the present moment worldwide waning fossil fuel resources as well as the tendency for developing new renewable biofuels have shifted the interest of the society towards finding novel alternative fuel sources. Biofuels have been put forward as one of a range of alternatives with lower emissions and a higher degree of fuel security and gives potential opportunities for rural and regional communities. Biodiesel has a great potential as an alternative diesel fuel. In this work, biodiesel was prepared from waste cooking oil it was converted into biodiesel through single step transesterification. Methanol with Potassium hydroxide as a catalyst was used for the transesterification process. The biodiesel was characterized by its fuel properties including acid value, cloud and pour points, water content, sediments, oxidation stability, carbon residue, flash point, kinematic viscosity, density according to IS: 15607-05 standards. The viscosity of the waste cooking oil biodiesel was found to be 4.05 mm2/sec at 400C. Flash point was found to be 1280C, water and sediment was 236mg/kg, 0 % respectively, carbon residue was 0.017%, total acid value was 0.2 mgKOH/g, cloud point was 40C and pour point was 120C. The results showed that one step transesterification was better and resulted in higher yield and better fuel properties. The research demonstrated that biodiesel obtained under optimum conditions from waste cooking oil was of good quality and could be used as a diesel fuel.

Abstract In this study, exergy, energy, performance and emission analysis were investigated for the repurpose used cooking oil (RUCO), Jatropha curcas (JC), Pongamia Pinnata (PP) and petroleum diesel fuel (PDF) fueled compression ignition engine under various engine loads. In this study, 20% of each biodiesel was tested in single cylinder, four stroke, diesel engine, given that open literature shows the potential use of biodiesel of up to 20% in a diesel engine without modification. The diesel engine was used to investigate their performance, combustion and emission characteristics of diesel-repurpose used cooking oil, Jatropha curcas, and Pongamia Pinnata fuel samples at different compression ratios and load condition. The results showed that thermal efficiency is higher with the PDF compared to DRUCO20, DJC20, DPP20 biodiesel blends. The exhaust gas temperature decreased and specific fuel consumption of the engine were increased by adding RUCO, Jatropha curcas, Pongamia Pinnata to petroleum diesel fuel. Engine ecological analysis showed that blended fuel reduces the average hydrocarbons (HC), carbon monoxide (CO) and NO X than petroleum diesel fuel. While DRUCO20 showed better performance and reduction in ecological analysis but higher ecological of CO 2 is comparable with DCJ20 and DPP20.
