Analytical optimization of biodiesel synthesis from seasonal mixed seed oils using Bara Gokhru nano-biocatalyst

Abstract

Hevea brasiliensis, Madhuca longifolia, Millettia pinnata, Bombax ceiba, and Poinciana regia, ensuring a consistent year-round supply of extraction of oils and are then blended in different ratios and analyzed. A biocatalyst derived from Bara Gokhru undergoes separation, with SiO₂ nanoparticles isolated and characterized. Response surface methodology was optimized the process parameters such as 0.35 (v/v) methanol/oil ratio, 7 wt% nano-biocatalyst, 900 rpm speed, and 70 °C heating for 175 min process to achieve 95 % biodiesel. The results were again optimized through following techniques: feed forward back propagation network, cascade-forward back propagation network, Elman back propagation network, and layer recurrent neural network to predict an optimized value. Recoverable methanol and catalyst enhance cost-effectiveness and promotes environmental sustainability, with the catalyst successfully reused five times. The right proportions such as 57.03 % saturated, 28.36 % monounsaturated and 13.49 % polyunsaturated fatty acids were ensured the compatibility of biodiesel which, leads large-scale production with industrial standards.
