“…Laminar premixed hydrogen flames doped with n -pentanol and some of its isomers were studied by Köhler et al using electron ionization molecular beam mass spectrometry (EI-MBMS), thus providing additional validation data for kinetic model development. For n -hexanol, speciation data of its oxidation in a counterflow diffusion flame have been reported by Yeung and Thomson, which to our best knowledge is the only study among those on the higher alcohols or ethers relevant for the present review where speciation data have been acquired in a nonpremixed configuration.…”

High molecular weight alcohol and ether fuels with their advanced autoignition propensities and oxygenated molecular structures are promising future fuel candidates for compression-ignition engine application, because they can provide improved combustion efficiencies and reduced pollutant emissions. In addition, their production from lignocellulosic biomass as second-generation biofuels offers an improved CO2 balance and avoids the adverse impact of the first-generation biofuel production on the food supply. This review aims to summarize the recent research progress on the combustion of long-chain alcohols and ethers with more than four carbon atoms, putting a particular emphasis on their fundamental combustion kinetics. The article starts with aspects related to their production routes, physical and chemical properties, and practical applications, highlighting the resulting consequences for their potentials as renewable fuels in comparison with conventional diesel fuels. This is followed by a comprehensive evaluation of their fundamental ignition and combustion characteristics. The existing chemical mechanisms for the oxidation of higher alcohols and ethers are introduced in conjunction with discussions of their development approaches. Their reaction kinetics are further explored to understand the dependence of their combustion behaviors on the molecule’s structural features, such as functional groups and carbon chain length. In particular, the different influences of the molecule size on the cetane numbers of longer alcohols and ethers are analyzed. The review finishes with a discussion suggesting directions for future experimental and numerical investigations, which will allow deepening of the understanding of the combustion kinetics of higher alcohol and ether fuels.

“…Likewise, hexanol has many industrial applications owing to its hypotoxicity at low concentrations for use in cosmetic, textile and pharmaceutical industries (Fernández-Naveira et al 2017b). In addition, hexanol is considered for blending with diesel as an aviation fuel (Fernández-Naveira et al 2017b;Yeung and Thomson 2013).…”

Hexanol–butanol–ethanol fermentation from syngas by Clostridium carboxidivorans P7 is a promising route for biofuel production. However, bacterial agglomeration in the culture of 37 °C severely hampers the accumulation of biomass and products. To investigate the effect of culture temperature on biomass growth and higher-alcohol production, C. carboxidivorans P7 was cultivated at both constant and two-step temperatures in the range from 25 to 37 °C. Meanwhile, Tween-80 and saponin were screened out from eight surfactants to alleviate agglomeration at 37 °C. The results showed that enhanced higher-alcohol production was contributed mainly by the application of two-step temperature culture rather than the addition of anti-agglomeration surfactants. Furthermore, comparative transcriptome revealed that although 37 °C promoted high expression of genes involved in the Wood–Ljungdahl pathway, genes encoding enzymes catalyzing acyl-condensation reactions associated with higher-alcohol production were highly expressed at 25 °C. This study gained greater insight into temperature-effect mechanism on syngas fermentation by C. carboxidivorans P7.

Experimental and kinetic modeling study of 1-hexanol combustion in an opposed-flow diffusion flame

Abstract: Biofuels are of particular interest as they have the potential to reduce our dependence on petroleum-derived fuels for transportation. 1-Hexanol is a promising renewable long chain alcohol that can be used in conventional fuel blends or as a cosolvent for biodiesel mixtures. iii
