Biodiesel and green diesel generation: an overview

Abstract

First, second, third, and fourth-generation biofuels are continuously evolving as a promising substitute to petrodiesel catalyzed by energy depletion, economic and environmental considerations. Bio-diesel can be synthesized from various biomass sources, which are commonly divided into FAME and renewable biodiesel. FAME biodiesel is generally produced by the transesterification of vegetable oils and fats while renewable diesel is produced by hydro-deoxygenation of vegetable and waste oils and fats. The different generation, processing technologies and standards for FAME and renewable biodiesel are reviewed. Finally, the life cycle analysis and production cost of conventional and renewable biodiesel are described.

A review on biodiesel production from microalgae: Influencing parameters and recent advanced technologies

“…The lipid in microalgae or the whole microalgae cell can be utilized to produce gaseous fuels such as hydrogen and biogas, or liquid fuels such as ethanol and liquid hydrocarbon fuels (Sanghamitra et al, 2020). Therefore, the development of microalgae biomass energy at this stage includes biodiesel production from microalgae lipid by transesterification (Vignesh et al, 2021), methane production by anaerobic digestion (Qi et al, 2017), and production of hydrocarbon or crude oil-like substances by gasification and pyrolysis (Su et al, 2022; Figure 4). Biodiesel production from lipid in microalgae through transesterification is characterized by the advantages of high growth rate and lipid yield, tolerance to environmental stress, and low competition for land (Ebhodaghe et al, 2022).…”

Hydrothermal Liquefaction of Biomass as One of the Most Promising Alternatives for the Synthesis of Advanced Liquid Biofuels: A Review

“…Lastly, HVO has a higher oxidative stability than fatty acid methyl ester. However, its lubrication capacity is lower, and its CO 2 emissions are higher [ 15 , 26 , 27 , 28 , 29 ]. Table 1 presents a comparison of the characteristics of conventional diesel, biodiesel, and green diesel.…”

Waste plastic oil to fuel: An experimental study in thermal barrier coated CI engine with exhaust gas recirculation

“…Today, most automobiles on the road are powered by an internal combustion (IC) engine that works on fossil fuel. The usage of fossil fuels in IC engines accounts for a significant portion of worldwide greenhouse gas emissions (Vignesh et al., 2021). However, several alternative fuels, such as natural gas, biodiesel, and methanol, provide a chance for IC engines to reduce emissions and enhance efficiency (Venkatesan et al., 2021).…”
