Esters as a potential renewable fuel: A review of the combustion characteristics

Valeric Biofuels from Biomass‐Derived γ‐Valerolactone: A Critical Overview of Production Processes

“…Depending on the alkyl chain length, VE show different polarity, volatility, and ignition properties that make them suitable for biofuels compatible with gasoline or diesel. As shown in Table 1, the physicochemical properties of valeric esters [27] are comparable and/or, in some cases, even better than those of petroleum‐based fuels, [25] first‐generation and other second‐generation biofuels [29] . Therefore, VE have good potential as alternative fuels to be used in internal combustion engines.…”

“…[57] These catalysts were prepared by separate nucleation and aging steps, assisted by reduction-oxidation strategies using NaBH 4 . Different initial molar ratios of NaBH 4 /(Cu + Zr) (x = 10, 15,20,25) and Cu loadings between 9.5 and 9.9 % were used. These authors claimed that the homogeneous dispersion of CuO, the high surface area of the support (ZrO 2 ) with a controlled porous structure and a strong interaction between CuO and ZrO 2 in the CuO/ZrO 2 precursor could lead to a greater dispersion of the Cu and the formation of Cu + active sites.…”

“…The effectiveness of fuels in internal combustion engines depends on their physicochemical properties because these properties influence the engine ignition delay time, engine-out emissions, rate and period of combustion, engine pressure and temperature. [25] For instance, a relatively high BRON increases knock resistance, engine efficiency, and curtails engine-out emissions. The lower heating value (LHV) determines the energy content of the fuel, whereas a relative high oxygen content can reduce soot and particulate matter emissions.…”

Comparative Study on the H-Abstraction Reactions of Isopropyl Acetate and Propyl Acetate by HO2 and OH Radicals

“…The interest in alternative transportation biofuels is still growing. Among them, esters are the principal constituents of biodiesel produced through the transesterification of renewable lipid feedstock with alcohols. − Combustion characteristics, particularly of isopropyl acetate (IPA) and its isomer propyl acetate (PA), representative aliphatic organic ester (molecular structures are depicted in Figure ), have gained significant attention as promising renewable fuels and biodiesel models. − Despite their potential as additives for biodiesel, their kinetic characteristics of the H-abstraction reaction remain insufficiently explored to date.…”

Production of esters with numerous applications: Kinetics of Dowex 50W catalyzed transesterification of methyl acetate with three‐ and four‐carbon structured alcohols

“…(b) manufacture of plastics, safety glasses, artificial leather, surface-treating agents, plasticizers, sealants, adhesives, binders, thinners, and aerosols in addition to coatings for cans, coils, and industrial wood; (c) extractants for various intricate applications such as in the pharmaceutical industry; (d) constituents in the production of flavours and perfumes because of their agreeable scent or aroma [11][12][13] ; and (e) potential biofuel additives to improve biodiesel properties. [14][15][16][17][18] A side product of the different transesterification reactions conducted in this study is methanol, which is an interesting chemical species due to its multiple applications. It can be used as raw material for biodiesel production.…”
