“…Due to lower viscosity, the mixing rate of fuel with air was drastically improved causing enhanced combustion and lower HC emission (Venkata Ramanan and Yuvarajan 2016). In addition, the vaporization of hexanol was faster which increased the pace of vaporization (De Poures et al 2017;Sundar and Saravanan 2011). …”

“…Hexanol is slightly soluble in water but miscible with diethyl ether and ethanol. Two additional straightchain isomers of 1-hexanol, 2-hexanol, and 3-hexanol exist, both of which differing by the location of the hydroxyl group (De Poures et al 2017). For this study, analytical grade hexanol containing the maximum limits of impurities of cyclohexanone (1.1 vol%), water (0.3 vol%) and the rest being traces of other foreign alcohols.…”

“…Hexanol is a renewable feedstock obtained from glucose and lignocellulosic biomass by means of engineered micro-organisms like Clostridium species (De Poures et al 2017). Hexanol is obtained by anaerobic fermentation of lignocellulosic biomass such as rice straw, corn stalks and sugarcane bagasse, wood-pulp, saw-mill and paper-mill discards without much reliance on food crops.…”

“…The other possible reason for choosing hexanol as an alcohol is that hexanol is a 6-carbon straight-chain alcohol that has great potential as a blending component with diesel fuel owing to its higher energy density, higher cetane number, better blend stability and less hygroscopic nature than other widely studied lower alcohols like ethanol, methanol, and even butanol (De Poures et al 2017). The latent heat of vaporization, density, and viscosity of hexanol is also closer to that of diesel fuel compared to other alcohols (De Poures et al 2017).…”

In this study, the effect of doping hexanol into biodiesel which is from neat cashew nut shell biodiesel oil on the emissions and the performance characteristics was studied in a constant speed diesel engine. The main purpose of this work is to reduce various emissions and also to improve the performance of the diesel engine when fueled with blends of hexanol and neat cashew nut shell biodiesel. Cashew nut shell oil is not edible, and hence it can be used as a viable alternative to diesel. Cashew nut shell biodiesel is prepared by conventional transesterification. Hexanol with 99.2% purity was employed as an oxygenated additive. Experimental studies were conducted by fueling diesel as a baseline and by fueling hexanol and neat cashew nut shell biodiesel mixture. A fuel comprising 10% (by volume) of hexanol and 90% (by volume) neat cashew nut shell biodiesel was referred to as CNSBD900H100 and fuel comprising 20% (by volume) of hexanol and 80% (by volume) of neat cashew nut shell biodiesel was referred to as CNSBD800H200. This study also investigated the possibility of using pure biofuel in an unmodified naturally aspirated diesel engine. The outcome of this study showed that adding hexanol at 10% and 20% (by volume) to cashew nut shell biodiesel results in a reduction in emissions. In addition, a significant improvement in brake thermal efficiency and reduction in brake-specific fuel consumptions were achieved. Hence, it could be concluded that hexanol could be a viable and promising additive for improving the drawbacks of biodiesel when it was used to fuel an unmodified diesel engine.

Biofuels such as renewable alkanes and higher alcohols have drawn considerable interests for the use in internal combustion engines. Especially, higher alcohols could be used as a blending agent for diesel fuels. Herein, carbon supported phosphated ruthenium-molybdenum (RuMoP) catalysts were employed in continuous trickle-bed reactor for converting sorbitol into renewable alkanes and higher alcohols. The results showed that RuMoP on an active carbon (AC) support presented a complete sorbitol conversion and high yields of alkanes and alcohols in gasoline and diesel range. Subsequently, carbon nanotube (CNT) supported RuMoP was prepared and studied in detail for comparison. RuMoP/CNT presented a low CÀC bond cracking property in sorbitol conversion and high selectivity of C6 products in gas-phase (C6 alkane, 74.7 %) and oil-phase (C6 alkane and alcohols, 87.8 %). Finally, detailed characterizations (N 2 -adsorption, XRD, HRTEM, XPS, NH 3 -TPD, Py-IR spectrums, etc.) were performed over relevant catalysts (RuMoP/C and RuMoP/CNT) for correlating their catalytic and physicochemical properties.[a] Dr.

Mixed oxides derived from the calcination of modified hydrotalcites precursors with copper and lanthanum were synthetized by the co‐precipitation method and characterized and applied as catalysts for ethanol Guerbet coupling reactions. The oxides obtained were used to convert ethanol into 1‐butanol and long‐chain alcohols, mostly 1‐hexanol. The selectivity for 1‐butanol and 1‐hexanol reached 62% and 10% for Cu‐MgAl(O) at 280°C. The addition of 1 mol% of La3+ (CuLa‐MgAl(O)) increased the number of basic sites comparing to Cu‐MgAl(O) changing the selectivity for 1‐butanol and 1‐hexanol reaching 16.70 and 41.7% at 280°C. The addition of lanthanum and consequently the increase on the catalyst basicity was related to the obtainment of long‐chain alcohols due to the enolate formation during the aldol condensation of Guerbet coupling.
