“…The quality and quantity of the biodiesel are evaluated by its fatty acid profile and its important properties. 71 The percentage of saturated and unsaturated fatty acids decides the quality of biodiesel because saturated fatty acid maintains better oxidation stability and cetane number and unsaturated fatty acid enhance the cold flow properties. 72 The fatty acid composition of CPO, MLO, AIO and MIO are shown in Figure 8(a)-8(d) respectively.…”

Rapid industrialization and population expansion increased the demand for petroleum-based fuels, resulting in price hike and creates serious environmental issues. Biodiesel, a clean, renewable and long-lasting alternative and for large scale production needs readily available and sustainable feedstocks. Edible and non-edible plants are abundant in Southern India, particularly Ceiba penandra (CP), Mahua longifolia (ML), and Azadirachta indica (AI), which were employed in this study in combination. An efficient heterogeneous nano-catalyst CaO-TiO2 was synthesized and employed in the transesterification process due to its recoverability and insensitivity to FFA. The catalyst was subjected to characterize by FTIR, XRD and SEM with EDX mapping. Response surface approach is engaged in this study for cost-effective production. More than 95% biodiesel yield was achieved for Ceiba penandra oil (CPO), Mahua longifolia oil (MLO), Azadirachta indica oil (AIO) and their mixture (MIO) by optimization of significant reaction parameters and the best combination was obtained as methanol oil ratio (0.32, 0.46, 0.34 and 0.42 v/v), catalyst usage (5, 6.5, 6 and 4 wt.%), mixing intensity (750, 840, 700 and 540 rpm) and duration (80, 105, 85 and 85 min) respectively with constant temperature of 70°C. Fatty acid profile was characterized by chromatograph also established the properties by ASTM and EN guidelines to confirm its compatibility in the IC engine.

“…The ranges, actual, and coded levels of the independent parameters are given in Table 1 (Xie et al 2007;Martínez et al 2014;Manadee et al 2017). Twenty experiments with six replications were performed at the center points to estimate the error value, and the data is analyzed via a second-order polynomial as presented in the following (Halim et al 2009, Talebian-Kiakalaieh et al 2013, Aryasomayajula Venkata Satya Lakshmi, et al 2020, Zhang et al 2020…”

In this research, Capparis spinosa oil was used as a feedstock for biodiesel production in the presence of NaOH/NaX as a nano heterogeneous catalyst. The NaOH/NaX catalyst was characterized by XRD, SEM, and BET analyses. The transesterification reaction was optimized through response surface methodology (RSM) based on the central composite design (CCD) of experiments. The effects of key variables of catalyst weight, methanol to oil molar ratio, and time on the reaction were studied, and a precise discussion about the impact of each process variable on the biodiesel yield was carried out. The highest biodiesel yield was 90.33% for the optimum reaction conditions that include a constant temperature of 60 °C, methanol to oil molar ratio of 6.7:1, catalyst weight of 2.3 wt%, and reaction time of 1.24 h. Furthermore, all physicochemical properties of the produced biodiesel were matched to the ASTM standard. Based on the obtained results, Capparis spinosa oil is a suitable source for biodiesel production.

At present, biodiesel remains an untapped fuel source while crude oil reserves are being depleted. Extensive efforts are necessary to achieve efficient biodiesel production, but catalytic activity in methyl palmitate production remains unsatisfactory. In this study, we report the synthesis and organocatalyst activity of C‐arylcalix[4]‐2‐methylresorcinarene sulfonic acids for biodiesel production. The presence of a methyl group on an aromatic ring is expected to disturb the intramolecular hydrogen bonds; thus, each hydroxyl group could be utilized for the catalytic process. C‐arylcalix[4]‐2‐methylresorcinarene sulfonic acids were prepared from cyclocondensation and sulfonation reactions yielding compounds 1–6 at rates of 66.7%–86.6%. By evaluating the organocatalytic activity of the C‐arylcalix[4]‐2‐methylresorcinarene sulfonic acids, we found that 4 mol% of compound 5 exhibited the highest yield (97.8%) of methyl palmitate at 338 K for 6‐h reaction time, which is remarkable. These findings show that C‐arylcalix[4]‐2‐methylresorcinarene sulfonic acids are promising heterogeneous catalyst materials for biodiesel production.
