In this study, the optimum biodiesel conversion from crude castor oil to castor biodiesel (CB) through transesterification method was investigated. The base catalyzed transesterification under different reactant proportion such as the molar ratio of alcohol to oil and mass ratio of catalyst to oil was studied for optimum production of castor biodiesel. The optimum condition for base catalyzed transesterification of castor oil was determined to be 1:4.5 of oil to methanol ratio and 0.005:1 of potassium hydroxide to oil ratio. The fuel properties of the produced CB such as the calorific value, flash point and density were analyzed and compared to conventional diesel. Diesel engine performance and emission test on different CB blends proved that CB was suitable to be used as diesel blends. CB was also proved to have lower emission compared to conventional diesel.

Utilising pyrolysis as a waste tyre processing technology has various economic and social advantages, along with the fact that it is an effective conversion method. Despite extensive research and a notable likelihood of success, this technology has not yet seen implementation in industrial and commercial settings. In this review, over 100 recent publications are reviewed and summarised to give attention to the current state of global tyre waste management, pyrolysis technology, and plastic waste conversion into liquid fuel. The study also investigated the suitability of pyrolysis oil for use in diesel engines and provided the results on diesel engine performance and emission characteristics. Most studies show that discarded tyres can yield 40–60% liquid oil with a calorific value of more than 40 MJ/kg, indicating that they are appropriate for direct use as boiler and furnace fuel. It has a low cetane index, as well as high viscosity, density, and aromatic content. According to diesel engine performance and emission studies, the power output and combustion efficiency of tyre pyrolysis oil are equivalent to diesel fuel, but engine emissions (NOX, CO, CO, SOX, and HC) are significantly greater in most circumstances. These findings indicate that tyre pyrolysis oil is not suitable for direct use in commercial automobile engines, but it can be utilised as a fuel additive or combined with other fuels.

Acid And Base

Biofuels are renewable, nontoxic and ecofriendly fuels that can play an important role in automobile industries. They can successfully replace diesel fuel and helps in decreasing the import of crude oil. The discarded seed ofCalophyllunInophyllumwhich are planted in India mainly to prevent soil erosion is considered as the possible source for extracting biodiesel. Thetamanuoil extracted had a fatty acid value of 48 mg KOH/g, therefore a two stage esterification processes with acid and base catalyst were used for converting it into biodiesel. The fuel was then tested for properties such as viscosity, calorific value and carbon residue using standard test procedures and found to be analogous with diesel, which makes it possible to use this alternate fuel in the existing engine without any modification. A single cylinder, four stroke, constant speed, variable compression ratio, direct injection diesel engine developing 5KW power with provision for computerized data acquisition is used to evaluate the performance and emission characteristics. The test results were analyzed for biodiesel and its blends in comparison with standard diesel at different compression ratios (16:1, 18:1, 20:1 & 22:1). The performance and emission results of the diesel engine revealed that biodiesel can be blended with diesel up to 40% at an optimum CR of 20, in order to get improved performance and reduced emission.

Alternative Feedstock

Biodiesel is one of the promising renewable sources to fulfill the future energy demand of the world. Sustainable feedstock for biodiesel production is one of the major criteria to ensure the process of renewability. Chicken fat is an encouraging feedstock for biodiesel. In this study, waste chicken fat was converted to biodiesel via catalysed transesterification. Optimised process parameters were recorded at 1:4 oil-to-methanol volume ratio and 0.5 wt% KOH catalyst concentration with a biodiesel yield of 96%. The FT-IR spectral analysis of chicken fat and chicken fat biodiesel confirmed the conversion of chicken fats into biodiesel. The physico-chemical properties of biodiesel were tested in accordance with ASTM D6751 and EN 14214 biodiesel standards. The specific fuel properties of chicken fat biodiesel that include calorific value, viscosity and acid value were found to be lower than that of petrodiesel. The diesel engine performance tests confirmed that the biodiesel blends performance was similar to petrodiesel.  It is noted that while the brake horsepower increased with the increase of biodiesel blending percentage, the engine power output was found to decrease. Specific fuel consumption also increased along with the biodiesel blending percentage.
