Biodiesel as an alternate fuel for future energy production: A review

There has been a significant growth in aviation industry due to the increased consumption of aviation fuel which is one of the main sources of anthropogenic CO2 emissions. As a result, using aviation fuels made from renewable resources has drawn a lot of attention. There have been significant attempts made to create renewable fuels as alternatives to petroleum-based fuels in order to provide a conservative approach for mitigating CO2 emissions from the air transportation sector. Non-edible oils combined with diesel are preferred as biofuels due to the growing global population and the rising need for edible oils and food crops. Various non edible oils which include candle nut, soap nut, jatropha, groundnut, canola, karanja, mahua, neem, jojoba, rubber seed oil, etc., are employed to produce biofuel. These biodiesels are prepared from the raw oil by a two-step co-solvent esterification process. In this study, an attempt is made to compare the important performance parameters of biodiesel blends made from both edible and non-edible sources. Brake thermal efficiency and brake specific fuel consumption of known biodiesel samples are evaluated based on the reported test results. Emission parameters includes carbon monoxides, carbon di oxides, smoke, and nitrogen oxide emissions are also compared.

Automated summary

The growth of the aviation industry is driven by the increased consumption of aviation fuel, which contributes significantly to anthropogenic CO2 emissions. In response, there has been a focus on developing renewable aviation fuels as alternatives to petroleum-based fuels. Non-edible oils combined with diesel are preferred for biofuels to meet the growing global demand for edible oils and food crops. This study compares important performance parameters of biodiesel blends from both edible and non-edible sources, including brake thermal efficiency, brake specific fuel consumption, and emission parameters such as carbon monoxide, carbon dioxide, smoke, and nitrogen oxide emissions.
