“…Therefore, the second-generation bio-feedstock, such as non-edible oils, used frying oils, animal fats, and greases, has the potential to be more popular in the market. The result showed that the second generation biodiesel from biomass feedstock emits fewer GHG than the first generation diesel from biomass feedstock [144]. In the preparation of biodiesel, the use of catalysts affects the results of LCA [145][146][147].…”

Energy consumption from transport has been increasing at a fast rate and become a major sector, which takes 29% of total global energy demand. Since transport energy consumption primarily relies on fossil fuels, it has resulted in serious carbon emissions and environmental degradation. Moreover, the volatility prices of fossil fuel and unstable international security have attracted keen interest for many developing and industrialized countries looking for sustainable and clean alternatives. Liquid biofuels, including but not limited to bioethanol, biodiesel, bio-jet fuel, are considered as the most promising alternative and more expansive role in powering sustainable transport, for its carbon neutral and low-emissions properties. Liquid biofuels contribute 4% of transport in 2020 and have been foreseen to continuously grow. Liquid biofuels can be produced by diverse technologies and commercialized in various ways, easy-adapt to technical and policy challenges. Major challenges include technical bottleneck, initial and operational cost, byproduct treatment, and associated environmental concern. This paper critically reviews: (1) Categories and production of different liquid biofuels; (2) Application scenarios of liquid biofuels; (3) Environmental impact assessment of liquid biofuels; (4) Opportunities and challenges of liquid biofuels; (5) Future perspectives. Each type of liquid biofuel requires specific production processes and has a strong correlation with biomass raw materials. Liquid biofuels find extensive applications in transportation, aviation, and other functional domains. In addition, the life cycle assessment of liquid biofuels is carried out from the numerous aspects of raw materials, pretreatment, production process, and application. Furthermore, this study analyzes the related policies, highlighting the challenges associated with the unstable supply of clean energy, raw materials, and quality control. Finally, the future perspectives of liquid biofuels were presented. This comprehensive review aims to provide a systematic understanding of liquid biofuels, covering their production and applications from multiple perspectives, while offering insights into future developments.

The demand for sustainable alternative-fuels in the transportation and agriculture domains is essential due to the quick depletion of petroleum supplies and the growing environmental challenges. The ternary-blends (diesel, biodiesel, and Methyl oleate) have the ability to report the existing challenges in this area because they offer significant promise for reducing exhaust emissions and improving engine performance. In the current work, soy methyl ester is blended with methyl oleate and diesel. The emissions and performance of blended biodiesel was conducted in common rail direct injection engine (CRDI). The characterization and physical properties were also evaluated by utilizing various methods like Fourier-Transform Infrared Spectroscopy (FTIR), UV-vis Spectroscopy (UV-vis), and Nuclear Magnetic Resonance. FTIR spectra showed the existence of the strong C=O, indicating the presence of FAME at 1745 cm−1. Again, UV-vis has reported the appearance of conjugated dienes in the oxidized biodiesel. The results indicated all blended samples retained the properties of diesel. The addition of methyl oleate improved brake specific fuel consumption of blended biodiesel almost near to diesel. D50::S80:M20 produced a mean reduction in hydrocarbon 42.64% compared to diesel. The average carbon monoxide emission reduction for D50::S80:M20 was 49.36% as against diesel.
