“…For the FFA adsorption process, the values of k 2 (1.87 × 10 -1 ) and q e (30.40 mg/g) were obtained at an R 2 (0.9986) for UPPA, while k 2 (3.0 × 10 -1 g/mg min) and q e (1.76 mg/g) respectively, following a coefficient of determination R 2 value of 0.9862 was recorded for the clay sorption of FFA. Studies have shown that a good kinetic model must have a good correlation coefficient for data fit closest to a unit (R 2 ≤ 1) 14,18 and the value of q e must be close to the experimental value 34,56 . Therefore, the Pseudo second-order model is more applicable in this experiment because the values of R 2 recorded for both ash and clay are greater than the R 2 values obtained from the Pseudo first-order model, and the calculated value of q e was closer to the experimental value.…”

The consumption of unrefined vegetable oil poses acute and chronic health issues, yet improper disposal of waste plantain peels is not environmentally sustainable. This research investigates the feasibility, mechanism and thermodynamics of waste plantain peels, and commercial bentonite clay for soybean oil refining. Experiment was carried out using masses (1–4 g) of commercial bentonite clay, and unripe plantain peel ash (UPPA) to degummed and neutralized free fatty acid (FFA) contents in crude soybean oil at varying temperatures (50–120 °C), and time (15–35 min) for treatment of soybean oil. FTIR spectroscopy, SEM, and XRF techniques were applied to characterize the sample. The results established that at optimum 4.0 g dosage, the UPPA (97.73%) was more effective in the removal of FFA from oil at 50 °C and 20 min, while the clay (90%) was more effective in the removal of colour pigment from the vegetable oil 100 °C, and 25 min. The optimum efficiency of Clay-Ash-composite (70:30) in adsorbing pigment from soybean oil corresponds to 80%. The impact of changing viscosities, densities, and acid values on the performance of UPPA, clay, and clay-UPPA composite was investigated. Mechanistic studies confirmed the pseudo-second-order kinetics at 5 × 10–2 g/mg min−1 and 1.87 × 10–1 g/mg min−1, with corresponding adsorption capacity of 30.40 mg/g and 4.91 mg/g, at R2 ≤ 0.9982. The UPPA-driven sorption of FFA occurred as a physisorption and exothermic process (− 620.60 kJ/mol), while colour pigment removal occurred by chemisorption and endothermic process (22.40 kJ/mol). The finding recommends UPPA and composite as economically feasible for refining soybean oil.

The objective of this study is to investigate the potential reduction in corrosion of aluminum and copper metals when exposed to biogas purified by activated carbon derived from cashew branches. Both aluminum and copper metals were subjected to raw and purified biogas, and their corrosion rates were analyzed using the gravimetric method. The results revealed that the corrosion rate of both metals increased over time when exposed to unfiltered biogas. However, a notable reduction in corrosion rate was observed when the metals were exposed to biogas filtered with activated carbon. This suggests that activated carbon derived from cashew branches could effectively mitigate the corrosive effects of hydrogen sulfide in biogas. Additionally, the study found that aluminum exhibited greater resistance to corrosion compared to copper when exposed to filtered biogas. This research on green inhibitors introduces novel approaches, particularly in utilizing activated carbon from cashew branches for biogas purification, offering a promising strategy to mitigate its corrosive nature. Furthermore, the evaluation of this filtration method's efficacy in protecting aluminum and copper metals underscores its potential significance in corrosion prevention within biogas systems.
