Abstract
Pyrolysis, as a thermochemical conversion of biomass, is a superior biofuel production procedure. The determining procedure for the optimal operational parameters, biomass characteristics, and types is outstandingly complex. Machine learning (ML) models were applied to enhance the predictive performance of three biofuel yields (bio-char, bio-oil, and syngas). This study aimed to establish seven ML models by utilizing the extracted experimental datasets of various pyrolysis routes of biomass (walnut shells and seed cake). The yields of three biofuels are mostly estimated at 0.95 to 0.99 of R-squared. Moreover, the sensitivity analysis displayed that species of biomass and pyrolysis conditions exhibited high errors (5.26–5.62% and 2–4.63% of MAPE) by excluding them from the input set for yield predictions. The generalizability of the ML technique is observed. The radial basis function (RBF) is highly capable of estimating biofuel yield. Genetic algorithms based on radial basis function (GA-RBF) optimization are applied in two ways: single bio-fuel and biomass species. The optimal yields achieved 36.04, 45, and 54.16% for the three biofuels, respectively. Three types of ML demonstrated the high feasibility of biofuel yield prediction. The findings provide strong evidence for using the potential of ML as an assistant along with desirable biofuel production.
