Developments in biobutanol production: New insights

Continuous two stage acetone–butanol–ethanol fermentation with integrated solvent removal using Clostridium acetobutylicum B 5313

“…Decanol has also been preferred as an extractant by various researchers due to its higher butanol distribution coefficient over oleyl alcohol; however, it was found to be toxic to the microorganisms when used alone (Assobhei et al, 1998;Qureshi et al, 2005). In this context, the optimization of these two consequences (toxicity and distribution coefficient) resulted in the use of a mixed extractant containing 20% decanol in oleyl alcohol which was found to be suitable for maximum butanol extraction with less toxicity, and the results are in agreement with other researchers (Qurashi et al, 2005;Kumar and Gayen, 2011). The optimum ratio of broth to extractant was found to be 1:1.5 and results remained unchanged at higher proportion of the extractant (data not shown).…”

Insights into Stoichiometric and Lean Combustion Phenomena of Gasoline–Butanol, Gasoline–Ethanol, Iso-Octane–Butanol, and Iso-Octane–Ethanol Blends in an Optical Spark-Ignition Engine

“…Butanol is a new alternative fuel that carries prospects for wide use in the future; its production processes are already established and despite remaining challenges it is expected that butanol can have similar market share to that of ethanol in the future (Garcíaa et al 2011;Kumar and Gayen, 2011). Butanol is more compatible with common materials and no major modifications are required to standard refuelling infrastructure processes and fuel injection systems for combustion in engines.…”

Production of Biofuels from Cellulose of Woody Biomass

“…Butanol has similar energy density and polarity to those of gasoline [71]. It has an adequate blending ability with gasoline and compatibility to combustion engines [72]. It can be shipped through existing fuel pipelines, whereas ethanol must be transported via rail and truck [73,74].…”
