Hydroprocessing of vegetable oil to high‐quality jet fuel range hydrocarbons (HRJ) plays a significant role in the development of completely interchangeable substitute for conventional petroleum‐derived jet fuel and has drawn the attention of aviation experts due to its capacity to mitigate greenhouse gas emissions associated with the aviation industry. The limited performance of 1 wt. % Sn promoted Fe(3)‐Cu(13)/SiO2‐Al2O3 catalyst in our previous study has been attributed to the successive consideration of one variable at a time in its evaluation. Maximization of oleic acid conversion and selectivity of jet fuel range hydrocarbons from hydroprocessing of oleic acid over 1 wt. % Sn promoted Fe(3)‐Cu(13)/SiO2‐Al2O3 catalyst with the best combination of the process parameter involved via multivariate approach, and evaluation of kinetic and thermodynamic activation parameters is the focus of this study. Reduced cubic oleic acid conversion model and reduced quadratic jet fuel range hydrocarbons selectivity model of high significance levels, adequate precision, and high correlation coefficient were developed. Reaction temperature of 339.5°C, 1.6 MPa H2 pressure, 6.2 wt.% catalyst concentration, and 8.0 h reaction time were optimum process parameters that can maximize oleic acid conversion and selectivity of jet fuel range hydrocarbons at 98.2% and 82.2%, respectively. This process was found to be endothermic, irreversible, and nonspontaneous with 45.8 KJ/mol activation enthalpy of reaction, 0.25 KJ/mol entropy of reaction, and the reaction's Gibb's free energy of 198.8 KJ/mol at 340°C. The minimum energy required for the reaction to take place was evaluated as 50.7 KJ/mol.

“…Literature reviews have revealed that there were no studies on the use of fusel oil in internal combustion engines at different compression ratios [16,18,23,[27][28][29]. This study fills a gap in the literature as it uses the waste fusel oil, a by-product obtained from the ethanol production processes of sugar production plants, as an alternative energy source to unleaded gasoline, a petroleum-based fuel, in a spark plug ignition engine [30,31]. Different physical and chemical characteristics of waste fusel oil and water as well as the gum and moisture ratios were analyzed according to the standard methods and were then accorded to the standards [32].…”

In this study, the effects of the use of improved fusel oil on engine performance and on exhaust emissions in a spark-ignition engine were investigated experimentally in consideration of the water, gum, and moisture content at high compression ratios according to TS EN 228 standards. In the study, a four-stroke, single-cylinder, air-cooled, spark plug ignition engine with an 8/1 compression ratio was used at three different compression ratios (8/1, 8.5/1, 9.12/1). Experiments were performed for six different ratios of fuel blends (F0, F10, F20, F30, F40, and F50) at a constant speed and different loads. The data obtained from the experiments were compared with the original operating parameters of the engine while using gasoline. According to the test results, the optimal engine performance was at a 9.12/1 compression ratio and with a F30 fuel blend. With the increase from an 8/1 to 9.12/1 compression ratio for the F30 fuel blend, the overall efficiency increased by 6.91%, and the specific fuel consumption decreased by 2.35%. The effect of the optimum fusel blend on the emissions was also examined and CO emissions were reduced by 36.82%, HC emissions were reduced by 23.07%, and NOx emissions were reduced by 15.42%, while CO2 emissions were increased by 13.88%.

“…Studies have focused on alternative energy sources that emit fewer polluting emissions compared to fossil-based fuels [13]. The most suitable alternative to fossil-based fuels is biodiesel and bio alcohols, which are described as biofuels [14,15]. Bio alcohols are generally obtained by subjecting plant wastes to biomass energy conversion processes.…”

In this study, experimental tests were carried out to improve the performance and emission characteristics of the diesel engine as amyl alcohol (pentanol), which is in the heavy alcohol class, obtained from the residual waste from etha-nol, which is produced as a by-product during sugar production from sugar beet. Tests were performed on naturally aspirated, air-cooled, four-stroke, single cyl-inder, direct injection, 6LD 400 Antor diesel engine at full load and engine speeds of 1400, 1700, 2000, 2300, 2600, 2900 and 3200 rpm. Pure diesel and fuel mixtures containing 5%, 10% and 20% amyl alcohol were used in the exper-iments. As a result of the experiments, while the power and torque values de-creased, the brake specific fuel consumption (BSFC) value increased as the ratio of amyl alcohol in the mixture increased compared to diesel fuel. In addition, the increase in amyl alcohol ratio in the mixture decreased hydrocarbon (HC), car-bon monoxide (CO), and smoke emissions, while increasing carbon dioxide (CO2) and nitrogen oxide (NOx) emissions. With 20% amyl alcohol ratio, an in-crease of 30.324% in BSFC value and a decrease of 13.745% and 10.258% in power and torque values were found as the average of all speeds, respectively. When evaluated in terms of emissions, with 20% amyl alcohol ratio, an average reduction of 44.565%, 42.832% and 27.330% was achieved in HC, CO, and smoke emissions, respectively, while NOx and CO2 emissions in-creased by 15.520% and 54.934%, respectively.
