“…Aromatic and cyclic compounds are major components of petroleum-based and bio-derived fuels. These types of compounds have been reported to comprise approximately 22% of catalytic hydrothermal conversion (CHC) diesel fuel, 40 mass % of gasoline, − 51 mass % of jet fuel, , 60% of CHC jet fuel, , 63 mass % ultralow sulfur diesel, more than 70 mass % for fuel from oils sands, and the majority of compounds found in biofuel from cellulose and lignin . The exact concentration depends on the source of the fuel and the processing of the biofuel.…”

The densities, viscosities, and speeds of sound of equimolar binary mixtures of benzene and n-alkylbenzenes, cyclohexane and n-alkylcyclohexanes, and n-alkylbenzenes and n-alkylcyclohexanes were measured. As the alkyl group on the molecules increased, densities, viscosities, and speeds of sound in mixtures increased, except for some mixtures with toluene and methylcyclohexane, where the property was the lowest of the mixture series. Excess molar volumes (V m E’s) were positive for all mixtures, and their values decreased with increasing alkyl chain length for mixtures of alkylbenzenes in cyclohexane or alkylcyclohexanes. For benzene mixtures, V m E’s increased with increasing alkyl chain length on cyclohexane, except for methylcyclohexane, which had the lowest V m E in the series. Viscosity deviations (Δη’s) were negative. As the alkyl group on the molecules increased, Δη increased to a maximum and then decreased to its lowest value. Excess isentropic compressibilities (K E’s) determined from density, speed of sound, and literature heat capacities were positive for benzene/cyclohexane mixtures. In general, K E’s decreased with increasing alkyl chain length for all mixtures. The similar trend in V m E’s and K E’s for the alkylbenzene mixtures suggests that the greater expanded volume allows for greater compressibility. For benzene mixtures, decreasing K E’s corresponded to increasing V m E’s, which suggests a complex packing arrangement.

“…MS acquisition was done in SCAN mode, analyzing m/z between 25 and 300 amu and included a 5 min solvent delay for liquid injections. Chromatograms were interpreted with Masshunter Qual software (Agilent, USA) and mass spectrum compared to the literature (Turner and Goodpaster, 2012;Naggar et al, 2017) and to the NIST MS 2.2 2017 database.…”

“…A typical fresh diesel fuel chromatogram is characterized by a dominance of n-alkanes peaks, appearing in a regular pattern and covering all the chromatogram (Christensen et al, 1993). Gasoline fuel is obtained from the distillation and cracking of crude oil (El Naggar et al, 2017). Cracking produces, from long chain alkanes, smaller alkenes at high temperature.…”

“…029x for biogasoline. Considering the compositions of RON95 gasoline and biogasoline, as evaluated by chromatographic analysis [29,30], it was possible to estimate an average carbon number of 7 for RON95 gasoline and 9 for biogasoline. Therefore, the complete combustion of RON95 gasoline, biogasoline, and ethanol with air can be described by Equations ( 11)-( 13), respectively:…”

Experimental Assessment of the Performance and Emissions of a Spark-Ignition Engine Using Waste-Derived Biofuels as Additives

et al. 2021

The use of biofuels for spark ignition engines is proposed to diversify fuel sources and reduce fossil fuel consumption, optimize engine performance, and reduce pollutant emissions. Additionally, when these biofuels are produced from low-grade wastes, they constitute valorisation pathways for these otherwise unprofitable wastes. In this study, ethanol and pyrolysis biogasoline made from low-grade wastes were evaluated as additives for commercial gasoline (RON95, RON98) in tests performed in a spark ignition engine. Binary fuel mixtures of ethanol + gasoline or biogasoline + gasoline with biofuel incorporation of 2% (w/w) to 10% (w/w) were evaluated and compared with ternary fuel mixtures of ethanol + biogasoline + gasoline with biofuel incorporation rates from 1% (w/w) to 5% (w/w). The fuel mix performance was assessed by determination of torque and power, fuel consumption and efficiency, and emissions (HC, CO, and NOx). An electronic control unit (ECU) was used to regulate the air–fuel ratio/lambda and the ignition advance for maximum brake torque (MBT), wide-open throttle (WOT)), and two torque loads for different engine speeds representative of typical driving. The additive incorporation up to 10% often improved efficiency and lowered emissions such as CO and HC relative to both straight gasolines, but NOx increased with the addition of a blend.
