In this research, artificial neural network (ANN) and response surface methodology (RSM) were used to predict the extraction yield (EY) of bio-oil from Mangifera indica wood (MIW) sawdust. The optimized ANN-FFBP and RSM-CCD models were developed, with the ANN-FFBP model showing superior performance. The analysis of the bio-oil revealed the presence of valuable compounds, and various techniques confirmed the commercial significance of the extracted pyrolysis products. Techno-economic assessment indicated a profitable margin for bio-oil production at an industrial scale of 10 TPD.
In this research article, application of artificial neural network (ANN) and response surface methodology (RSM) is employed to predict the extraction yield (EY) of bio-oil from the pyrolysis of Mangifera indica wood (MIW) sawdust, developing the two optimized models (i.e., ANN-FFBP and RSM-CCD). The effect of three input pa-rameters with their ranges, viz. particle size (0.2-0.8 mm), temperature (430-630 degrees C), and N2-gas flow rate (60-160 mL/min) on EY of MIW bio-oil are investigated. The Levenberg-Marquardt (LM) algorithm is used to train the network and an ANN-FFBP based model is developed for predicting the EY. Sensitivity analysis confirmed the superiority of optimal ANN-FFBP [3-9-1] model over the optimized RSM-CCD model with the values (AARD%= 0.25945, MSE = 0.00001 and R2 = 0.99711). The maximum EY of bio-oil (45.50 mass%) was observed at optimum conditions of parameters (0.6 mm, 564 degrees C, and 120 mL/min). The analysis of bio-oil through GC-MS confirmed the presence of high-valued compounds, e.g., methylenecyclopropanecarboxylic acid (8.11 mass%) and p-Cresol (11.41 mass%). In addition to this, the commercial significance of the extracted pyrolysis products has been confirmed via FTIR, ignition point, elemental analyzer, 1H NMR, and FE-SEM-EDX. Moreover, the techno-economic assessment of bio-oil production at industrial scale of 10 TPD assured a profit margin of 109-128 % for per kg production of bio-oil.
