“…The selection of the methanol to oil molar ratio and the catalyst amount was made to study the effect of using minimum amount of catalyst (to reduce costs) and methanol (to reduce the cost associated with its recovery after reaction). The effects of reaction time, temperature, agitation speed, mole ratio of alcohol and different ratios of catalyst concentration were studied in the production of biodiesel in this research work [10]. This was accomplished using the BBD of response surface methodology (RSM).…”

“…The uncertainty analysis of the developed equation was estimated by OCB through the determination of suitable probability distribution that can represent the developed equation. OCB with the aid of Monte Carlo simulation (MCS) set a trial period of 100,000 while the probability distribution and the rank of the coefficient are plotted as the output of this analysis as reported in a previous investigation [10].…”

“…Biodiesel production is primarily experimental research which predominantly relies on accurate measurement of all the variables that control its production. Proper material utilization with respect to optimal YB, profitability and feasibility study of the process is an important factor condition regardless of the source of biodiesel produced (from edible or non-edible oil and from homogenous or heterogeneous catalyzed production) [10]. In order to increase YB and the optimal variables that support it, response surface methodology (RSM) is a statistical method of analysis adopted for this study.…”

“…Various studies have been done successfully on the synthesis of biodiesel from different feedstock and catalysts [7,10,23,24] and YB depends on the effect of variables such as alcohol to oil ratio, alcohol-catalyst mixing/stirring, catalyst concentration, time of reaction and temperature of reaction [2]. These variables are used for the generation of data used for different modeling techniques [1,25].…”

This study conducted experiments used for the development of both the regression model with uncertainty analysis and the adaptive neuro-fuzzy inference system (ANFIS) model for the prediction of the yield of biodiesel (YB) produced from castor oil in the presence of calcium oxide derived from the eggshell. Box Behnken design (BBD) was used to develop the experimental condition for five different variables while YB was the response. Uncertainty analysis was determined from Monte Carlo simulation (MCS). The model was optimized and validated before the generated data was applied in the three ANFIS modelling techniques. Root mean square error (RMSE), coefficient of correlation (R 2 ) and average percentage error (APE) were used to determine the accuracy of the models developed. The result of this modelling shows that the optimum YB (94.29%) was achieved at a methanol to oil ratio of 11.48, catalyst loading of 3.38 wt%, reaction time of 1.84 h, the temperature of 60.2 °C, and agitation of 343.5 rpm. The prediction from BBD, ANFIS and MCS agreed that the methanol to oil ratio was the most important parameter for investigation. The considered ANFIS model technique (subtractive clustering) for the modelling of YB outperformed BBD model. The novelty of this study are the determination of the optimum condition for the transesterification of castor oil in the presence of thermally treated anthill, the establishment of the use of ANFIS in modelling YB, the prediction of the influence of variables on YB using both statistical and, AI techniques and validation of the predictions from the two methods using MCS.

“…Non-fossil fuels are becoming increasingly important due to their positive impact on reducing exhaust emissions. Studies examining a wide range of biofuels, synthetic fuels, and regenerative fuels have shown that the reduction in carbon dioxide emissions is possible without major changes in the existing infrastructure of internal combustion engines of agricultural machinery [5,6].…”

One of the main trends in the development of modern engine building is the use of biodiesel fuel, which can lead to a decrease in the reliability of engines that are not adapted to it. However, at present there is no general method for determining the reliability of fuel systems of internal combustion engines. In this paper, a reliability model of engine fuel systems when operating on biofuel has been developed. Comprehensive indicators for assessing the reliability of diesel engine fuel systems are the coefficient of readiness and technical use. The availability factor of the fuel system when operating on biodiesel fuel without the replacement of structural materials was 0.66, while with the replacement it was 0.71, and the coefficient of technical utilization without replacement of materials was 0.36, and with the replacement of 0.4. Recommendations are given to improve the reliability of the engine fuel system components. The resulting model allows for complex comparisons of the effectiveness of various ways to improve the reliability of engines running on biodiesel fuel.

Biodiesel represents a biodegradable, environmentally friendly, and renewable alternative to fossil fuels. Despite more than three decades of research, significant obstacles still hinder the widespread production of biodiesel. This current review elucidates both the potential and the existing challenges associated with homogeneous and heterogeneous catalysts in catalyzing biodiesel production, with a particular focus on alkali analogues, alkaline earth metal oxides, and titania‐based catalysts. In particular, a comprehensive analysis is presented concerning alkali and alkaline earth‐based titania (TiO2) catalysts. Among these, the alkaline earth metal oxides, including lithium, calcium, and strontium when combined with titanium‐based catalysts, exhibit superior catalytic activity compared to other metal oxides, owing to their heightened basicity. Consequently, this review offers a thorough and up‐to‐date insight into the potential of titania‐based heterogeneous catalysts for advancing biodiesel production.
