The Production and Comparison of Fuel Properties on Biodiesel with Alternative Fuel: A Review

Abstract

The energy is the most of the human existence. Consumption fossil fuels has grown substantially and consumption the energy sources that is seen as having a major environmental impacts. Diminution world oil reserves and increasing environmental concern have induced found alternative and renewable energy resources called biodiesel. Biodiesel fuel from the vegetable oil, regarded as of the best candidate for the substitute diesel fuel in diesel engines because of the characteristics closer. The application of biodiesel has shown a positive impact in resolving these issues. This paper introduces some type of alternative fuel whose oils are potential sources of biodiesel. These types are crude palm oil (CPO), straight vegetable oil (SVO), waste cooking oil (WCO) and Jatrophacurcas (JPO). From the review, fuel properties are found to considerably different on density, viscosity, acid value, water content and flash point as compared with standard diesel. In conclusion, a long period of storage will reduce the quality of biodiesel does not matter what kind of conditions and environments that are exposed to. However, the rate of degradation of biodiesel can be slow if the right circumstances and environment provided. IntroductionIn late years, alternative fuels, energy efficiency, environmental security, energy conservation and management have become significant due to depletion of fossil fuel and environmental degradation. The alternative fuels or so called biodiesel can be better tried for diesel engine as compared to gas engines because of the construction of the diesel engine is very full-bodied and can operate under high compression ratio along with a substantial quantity of extra air. Biodiesel fuel will mix with soft wind in the combustion chamber to go through compression ignition. After the ignition process, performance and emission are produced. In this study, the focus would be on Storage and handling of biodiesel fuels whereby storage and handling are significant factors which can influence the quality of biodiesel as it is prone towards degradation as compared to fossil fuel. Normally, fuel is stored in a large vessel or tank at outdoor spaces so it is exposed to natural environmental condition where the properties would vary according to the conditions. The constituents which could speed the degradation of biodiesel include air (oxygen), light (UV), elevated temperatures, trace of metal, peroxide and the surface area between biodiesel and air. Biodiesel fuel is more hygroscopic compared to diesel fuel. It bears a natural inclination to absorb wet and water which tend to concentrate on the metal surface, favoring the corrosion [1].Even though the exposure of biodiesel towards light and air are cut back to the minimum level, but after some time, traces of air and light will still slide through and come in touch with the biodiesel inside. To make matter worse, heat from surrounding, presence of metals and water in the fuel may still rush up the oxidation procedure. Also, contamination by bacteria or fu...

Effect of anti‐oxidants on the lubricity of B30 biodiesel–diesel blend

“…To overcome this problem, oil is converted to biodiesel, which is less viscous and more efficient . It is environmental friendly, non‐toxic and biodegradable . In environmental issues, biodiesel is more acceptable compared with conventional diesel fuel.…”

“…18,19 It is environmental friendly, non-toxic and biodegradable. [20][21][22] In environmental issues, biodiesel is more acceptable compared with conventional diesel fuel. Due to its higher percentage of oxygen content, combustion process is better; it forms low carbon and smoke, which are good for human body and do not contribute to global warming.…”
