“…But from 3 to 4 hours the yield decreased to 87%. This is due to the transesterification reaction which is a reversible process which it conducts for reduction of higher yield of fatty acid methyl esters and production of soap 35 . However, the highest biodiesel yield of 92.1% was reached in 3 hours.…”

Summary Biodiesel was successfully produced by transesterification process of soybean oil and methanol using Ni0.5Zn0.5Fe2O4 nanomagnetic catalyst. The Ni0.5Zn0.5Fe2O4 catalyst was synthesized by the combustion method and its properties were investigated using X‐ray diffraction, N2 physisorption at 77 K, Fourier transform infrared analysis, thermogravimetric analysis, scanning electron microscopy, and a transmission electron microscopy. The performance of catalyst was investigated during transesterification reaction for fatty acid methyl esters (FAMEs) production. FAMEs were studied by gas chromatography technique. The effect of reaction conditions such as molar ratio of methanol/soybean oil, catalyst amount, reaction temperature, and reaction time on FAMEs yield was also evaluated. The biodiesel yield of 92.1% was obtained under the following reaction conditions: 9:1 of methanol/soybean oil molar ratio and, 2% of catalyst loading at 180°C in 3 hours. Furthermore, the energy of activation (Ea) was 67.4 kJ.mo1−1 and the pre‐exponential factor (ko) was 8.35 × 104 L mol−1 min−1 determined using Arrhenius equation.

“…That means it is important to convert agricultural waste into useful materials to reduce its effect on the environment. One of these useful materials is the production of a useful catalyst [8][9][10]. our work is interesting in the protection of the environment from the pollution caused by agricultural waste and diesel engine emissions.…”

Background: The world depends almost on fossil fuels. This leads to depletion of oil and an increase in environmental pollution. Therefore, the researchers search to find alternative fuels. Waste cooking oil (WCO) was selected as feedstock for biodiesel production to eliminates the pollution problems. The agricultural waste is very big and without cost, this leads to the use of the rice straw in preparing a catalyst for biodiesel production. Results: The reusability of the acidic catalyst confirmed that the conversion efficiency was high until after 8 cycles of the production. The highest conversion efficiency of the converting WCO extended to 90.38% with 92.5% maximum mass yield and methyl ester content 97.7% wt. at the optimized conditions. The result was indicating that B15 is the best blend for thermal efficiency and specific fuel consumption. All emission concentrations decrease with increasing the engine load, especially for B15 fuels compared to the diesel oil.Conclusion: The novelty of this paper is assessing the methyl esters from the local WCO as an alternative fuel for diesel engines using a heterogeneous catalyst based on the agricultural waste. The performance of the diesel engines and its exhaust emissions have been experimentally investigated with the produced biodiesel of WCO as a blend (B10, B15, and B20) compared to the diesel.
