Highlights • Multiple sample geometries revealed effects of particle size on char formations. • A negative carbonization/mass loss correlation occurred while increasing particle size. • Synthetic indexes built from model parameters depicted kinetic differences. • Model's prediction ability regarding particle sizes was validated. • Strategy proposed to predict char compositions for a given size at any temperature-time pathway.
