“…The testing was conducted as per the ASTM D6751 standards, and the result is presented in Table 4. Fuel properties such as viscosity, 40 flash point, 41 and cetane number 42 , 43 were found to be within the limit of standards. Hence, the proposed non-edible mixed oil is a suitable feedstock for biodiesel production.…”

Population, industrialization, and urbanization made to exploit high volume of fossil fuels such as diesel to meet energy demands. Excess application of fossil fuels created environmental and health threats, hike in oil prices, and depletion of resources. Biodiesel was termed as a predominant alternative renewable fuel for diesel engines. In this research, a novel fuel is produced from the mixed feedstocks such as castor oil, mahua oil, and processed dairy waste by mixing in equal volumes (each 33.33% v/v). An esterification reaction was performed initially, since the acid value of raw oil is found to be 4.11 mg KOH/g oil. Three different acid catalyst concentrations (1, 2, and 3% v/v) were used to ascertain the effect of acid catalyst concentration on the acid value of oil. The acid value of esterified oil from the esterification reaction tends to decrease with an increase in acid concentration. Transesterification reaction parameters such as catalyst utilization (wt%), reaction temperature (°C), and oil to methanol ratio (molar) were varied in three levels (27 transesterification experiments) based on the Taguchi method to find the optimal reaction parameters for maximum biodiesel yield, high fuel flash point, and low fuel viscosity. At the end of each transesterification reaction, biodiesel yield percentage, and its properties such as fuel flash point and viscosity were measured as per the ASTM standard (D6751). Based on the multi-criteria decision-making-GRA method, the optimal value for maximum biodiesel yield and fuel properties such as flash point and viscosity was determined as catalyst utilization (3 wt%), reaction temperature (55 °C), and a molar oil to methanol ratio of 12. In addition, an earthen lamp test was conducted and measured properties of fuel were delineated to reveal that the produced biodiesel from the mixed non-edible oil is an effective feedstock for biodiesel production.

“…The alcohol:oil molar ratio is one of the most critical reaction parameters affecting biodiesel yield. Although there is a 3:1 stoichiometric ratio between the oil and alcohol in the transesterification reaction, more stoichiometric ratios are needed to improve the mass transfer between the triglyceride and the alcohol molecule and to increase miscibility (Almasi et al 2021 ). Methanol:HSO molar ratios of 3:1, 5:1, 7:1, and 9:1 were studied using 60 °C and 60 min stirring at 600 rpm.…”

Post-pandemic inflationist pressures, climate changes and extremes, regional conflicts, and soaring food prices caused the food crisis to increase rapidly worldwide. This global problem directs producers and researchers to use oils used as feedstock in biodiesel production effectively. In this context, it is important to assay the transesterification parameters and conduct new optimization studies to increase biodiesel yield. In this study, methyl ester was produced from hemp oil by transesterification using sodium hydroxide (NaOH). Next, classical optimization study was carried out to determine the effects of catalyst amount, alcohol:oil molar ratio, reaction temperature, and reaction time variables on biodiesel yield. Secondly, the cubic spline mathematical model (CSMM) and polynomial regression mathematical model (PRMM) were applied to the first data of this optimization. Among these optimization methods, the utmost biodiesel yield registered was 96.115% at hemp seed oil (HSO):methanol molar ratio of 5.59:1, catalyst concentration of 0.531 wt%, reaction temperature of 42.5 °C, reaction time of 62.1 min, and agitation intensity of 600 rpm at PRMM. Some vital fuel properties obtained from HSO biodiesels as a result of three optimizations satisfied the EN 14214 standard. The results illustrated that the optimal yields from CSMM and PRMM are 0.765% and 1.065% higher, respectively, according to the maximum efficiency obtained from the classical optimization. The outcomes showed that CSMM and PRMM are cost-effective, easy to handle, and promising new approaches.

“…This is an ideal alternative to fossil fuels owing to its clean, degradable, renewable, and sustainable properties [3] , [4] . However, using vegetable oils to produce biodiesel threatens food security because they are not economical [5] . Therefore, using non-edible oils to produce biodiesel is crucial to balance food and energy demands.…”
