This study investigates the intricate relationship between biomass preprocessing and pyrolysis product yields, employing air classification technique for treatment of loblolly pine residues with varying moisture content. A comprehensive exploration physicochemical properties air-classified informs a sophisticated simulation model. Given complex multifaceted nature pyrolysis, operating across diverse temporal spatial scales, kinetics-based CFD–DEM method is employed to predict yields. Results showed that elevated content amplifies particle adhesiveness, necessitating augmented velocities effective separation, thereby influencing efficiency separation process. While carbon hydrogen contents exhibit relative stability blower frequencies, oxygen undergoes noticeable changes. For example, were measured as 29.2 38.6 wt% in light fraction 30 % sample at frequencies 10 20 Hz, respectively. An intriguing finding emerges from simulation, indicating lower frequency moderately enhances bio-oil yield significantly improves its quality, particularly terms water instance, was about 1.5 heavy fractions, respectively under 15 Hz frequency. In summary, detailed understanding strategic manipulation critical material attributes through efficient fractionation techniques are imperative advancing fast sustainable avenue renewable energy chemical production.
