“…Renewable fuels, such as biodiesel, have been proposed to replace petroleum fossil fuels to reduce global CO 2 emissions. Biodiesel is non-toxic and environmentally beneficial [8]. Furthermore, when compared with fossil fuels, biodiesel fuel can cut CO 2 emissions by about 78.45% [8].…”

The fuel qualities of several biodiesels containing highly saturated, mono, and poly unsaturated fatty acids, as well as their combustion and exhaust emission characteristics, were studied. Six biodiesel samples were divided into two groups based on their fatty acid composition, including group 1 (coconut, castor, and jatropha) and group II (palm, karanja, and waste cooking oil biodiesel). All fuels (in both groups) were tested in a single-cylinder off-road diesel engine. Castor and karanja biodiesel, both rich in mono-unsaturation level, have a high viscosity of about 14.5 and 5.04 mm2/s, respectively. The coconut and palm biodiesels are rich in saturation level with cetane numbers of 62 and 60, respectively. In both groups, highly saturated and poly-unsaturated methyl esters presented better combustion efficiency and less formation of polluted emissions than mono-unsaturation. At full load, coconut and palm biodiesel displayed 38% and 10% advanced start of combustion, respectively, which reduced ignition delay by approximately 10% and 3%, respectively. Mono-unsaturated methyl esters exhibited a higher cylinder pressure and heat release rate, which results in higher NOx gas emissions. The group II biodiesels showed about 10–15% lower exhaust emissions owing to an optimum level of fatty acid composition. Our study concluded that highly saturated and poly-unsaturated fatty acid performed better than mono-unsaturated biodiesels for off-road engine application.

“…Biodiesel is considered the most carbon neutral fuel with the ability to reduce carbon dioxide emissions by 78% compared to diesel fuel. Moreover, the biodegradability of biodiesel has been proven to be really high, ranging from 80.4% to 91.2% after 30 days while fossil diesel only has 24.5% biodegradability [9,18]. Another advantage using biodiesel is that its emission content is considered less harmful to the environment.…”

Biodiesel has caught the attention of many researchers because it has great potential to be a sustainable fossil fuel substitute. Biodiesel has a non-toxic and renewable nature and has been proven to emit less environmentally harmful emissions such as hydrocarbons (HC), and carbon monoxide (CO) as smoke particles during combustion. Problems related to global warming caused by greenhouse gas (GHG) emissions could also be solved by utilizing biodiesel as a daily energy source. However, the expensive cost of biodiesel production, mainly because of the cost of natural feedstock, hinders the potential of biodiesel commercialization. The selection of natural sources of biodiesel should be made with observations from economic, agricultural, and technical perspectives to obtain one feasible biodiesel with superior characteristics. This review paper presents a detailed overview of various natural sources, their physicochemical properties, the performance, emission, and combustion characteristics of biodiesel when used in a diesel engine. The recent progress in studies about natural feedstocks and manufacturing methods used in biodiesel production were evaluated in detail. Finally, the findings of the present work reveal that transesterification is currently the most superior and commonly used biodiesel production method compared to other methods available.

“…In Indonesia, the country with the 4 th largest population in the world, the consumption of petroleum was recorded at 1,785,000 barrels/day while the production of petroleum was only 778,000 barrels/day in 2019 (British Petroleum 2019, Dewan Energi Nasional 2019. The consumption of fossil fuels is also proven to be the main cause of climate change due to the emission of greenhouse gases into the atmosphere (Syafiuddin et al 2020). Therefore, an environmental-friendly alternative fuel is required to replace conventional fossil fuels.…”

“…The use of subcritical water and supercritical CO2 assisted with co-solvent can decrease both the medium pH and polarities of solvents leading to the higher rates of extraction, hydrolysis, and trans/esterification reactions, and therefore can decrease processing time and increase FAEE formation rate (Zullaikah et al 2019, Hassan et al 2020a, Hassan et al 2020b. The developed process is completely green since ethanol is used instead of methanol (Syafiuddin et al 2020). Moreover, since FAEE has a longer carbon chain than fatty acid methyl esters (FAME), it has higher cetane number (CN) and heating value (Bathia et al 2021).…”

Rice bran oil (RBO)is claimed to be a potential feedstock for biodiesel production. Non-catalytic in-situ biodiesel production from a low-cost feedstock (rice bran) using subcritical ethanol-water mixture was investigated in this study. The influence of four independent variables, i.e., addition of co-solvent, ethanol concentration, temperature, and time of reactions, on the yield of biodiesel was examined. The results showed that the most effective co-solvent wasethyl acetate and the optimum ethanol concentration, temperature and reaction time were 80% v/v, 200 oC and 3 hours, respectively. The maximum yield of biodiesel was found to be around 80%. The optimization of operating conditions was carried out by response surface methodology (RSM) with historical data design (HDD). The statistical method also suggested similar optimum operating conditions, i.e., 78.44% (v/v) ethanol concentration, 200 oC, and 3.2 hours reaction time with ethyl acetate as a co-solvent. The predicted maximum biodiesel yield was also slightly lower, i.e., 76.98%. Therefore, this study suggests that biodiesel production from rice bran through a non-catalytic in-situ process using a subcritical ethanol-water mixture with ethyl acetate as a co-solvent is very feasible since the yield can reach 80%. The study also found that RSM with HDD can predict the optimum operating conditions with a good accuracy.
