Abstract
This research comprehensively investigates hydrogen production optimization in pine sawdust gasification through integrated numerical simulation and experimental validation. The numerical model, developed using Aspen Plus®, demonstrated exceptional correlation with experimental data (R² > 0.95) at 800°C, validating its predictive capability. Parametric analysis revealed that elevating the reaction temperature from 600°C to 800°C significantly enhanced H₂ concentration from 31.12 vol% to 35.11 vol%, primarily due to the acceleration of endothermic water-gas shift (WGS) and steam reforming reactions. The equivalence ratio (ER) exhibited an inverse relationship with H₂ yield, where increasing ER from 0.2 to 0.4 resulted in a substantial decrease in H₂ concentration from 37.61 vol% to 30.07 vol%, attributed to the diminished steam availability for reforming reactions. Furthermore, augmentation of the steam-to-biomass (S/B) ratio from 0.5 to 1.7 facilitated increased H₂ concentration from 35.28 vol% to 37.22 vol%, owing to enhanced steam reforming and WGS reaction kinetics. Through multi-parameter optimization, optimal conditions were established at temperature: 750-800°C, ER: 0.2-0.25, and S/B ratio: 1.1-1.4, achieving maximum H₂ concentrations of 36-38 vol%.
