“…In their test experiments, they found that the thrust and specific fuel consumption levels from lower blending ratios (e.g., 15% of biodiesel) were also similar to those produced from kerosene, while extremely high blending ratios (e.g., 90% of biodiesel) significantly lowered the pollutant emissions with compensation in thrust loss. This is consistent with the conclusion of Boomadevi et al 103 that blending biodiesel at a low proportion level in Jet A fuel can produce a good result on both engine performance and emissions, but the results are not always positive as the addition proportion increases. Timko et al 104 investigated the biodiesel/jet fuel blend on a CFM56-7 gas turbine engine.…”

Biodiesel is one of the most promising low-carbon fuels and has been applied in internal combustion engines. In recent years, there have been emerging interests in the application of biodiesel in gas turbines, accompanied by the growing need for carbon reduction in the gas turbine industry. This mini review focuses on the fundamental combustion research of biodiesel and its model compounds, as well as its current application in gas turbines, mainly in the last 15 years. As for fundamental combustion research, selected advances in combustion chemistry and swirl combustion are reviewed. Diversity in molecular structures of biodiesel and its model compounds includes a vast amount of research on fuel molecular structure effects on combustion characteristics, including the effects of the functional group, chain length, and isomeric structure. Swirling flame studies of biodiesel are also reviewed, which focus on the flame shape, flame stability, atomization performance, and pollutant emissions. Combustion performances of biodiesel in aircraft and land-based gas turbine are also highlighted. Furthermore, some prospects of future research of biodiesel combustion with the purpose of gas turbine application are provided.

Recent environmental concerns raise fuel prices; hence we need the alternative petroleum source product. Currently, biodiesel is commercially produced from jatropha, cotton seeds, pongamia, mustard, chlorella emersonii (CE) seeds poses operational problems due to some of the lower calorific values, physical and chemical operation, and durability issues due to lower calorific value. In the current investigation, CE oil is adopted to generate CE Methyl Ester (CEME), while higher alcohol butanol is used. The performance of single-cylinder C.I engine at a steady speed of 1500 rpm using various blends of B1 (100% CE bio-fuel), B2 (80% volume of biodiesel and 20% volume of butanol), B3 (80% vol of biodiesel, 10% volume butanol, and 10% volume of distilled water) and diesel. This engine output, such as brake-specific fuel consumption (BSFC), brake thermal efficiency (BTE), and exhaust emission characteristics such as carbon monoxide (CO), carbon dioxide (CO 2 ), and hydrocarbon (HC) was measured for different load conditions. Also, the smoke opacity, exhaust gas temperature (EGT), cylinder pressure, ignition delay (ID), and heat release rate (HRR) were measured. The findings were positive for the efficient usage of biodiesel with the introduction of butanol and offset a portion of the rising energy demand properties.

“…The bio-oil is refined with H 2 SO 4 in the presence of catalyst CaO and with CH 2 OH in the presence of NaOH. The undesirable glycerol which is created in this process is removed to produce microalgae biodiesel as the final product . The data system was utilized in research to find the different fatty acid methyl esters contained in biodiesel …”

Fossil fuel depletion and environmental pollution are paramount problems the world faces. Despite several measures, the transportation industry is still battling to manage these issues. A combined approach of fuel modification for low-temperature combustion with combustion enhancers could offer a breakthrough. Due to their properties and chemical structure, biodiesels have piqued the interest of scientists. Studies have asserted that microalgal biodiesel might be a viable alternative. Premixed charge compression ignition (PCCI) is an easily adoptable promising low-temperature combustion strategy in compression ignition engines. The objective of this study is to identify the optimal blend and catalyst measure for improved performance and reduced emissions. Microalgae biodiesel at various proportions (B10, B20, B30, and B40) was amalgamated with CuO nanocatalyst and tested to arrive at the right concoction of biodiesel with nanoparticles in a 5.2 kW CI engine for different load conditions. The PCCI function warrants that about 20% of the fuel supplied is vaporized for premixing. Finally, the interplay factors of the independent variables of the PCCI engine were then explored by response surface methodology (RSM) to determine the optimal level of desired dependent and independent variables. The RSM experiment findings suggest that the best biodiesel and nanoparticle concoctions at 20%, 40%, 60%, and 80% loads were B20CuO76, B20Cu60, B18CuO61, and B18CuO65, respectively. These findings were experimentally validated.
