Bamboo charcoal obtained from the pyrolysis of bamboo chips was used to remove furfural, a representative fermentation inhibitor in hydrolyzates or pyrolysis oil. Kinetics, isotherm, and thermodynamic calculations were performed. The adsorption process can be well depicted by Ho’s pseudo-second-order model. The particle diffusion of homogeneous particle diffusion model (HPDM) and shrinking core model (SCM) was found to be the controlling step. Isotherm analysis indicated the adsorption feature took place by a nonideal adsorption. Thermodynamic calculation suggested that Delta H degrees > 0, Delta G degrees < 0, Delta S degrees > 0, and Ea value was 2.02 kJ/mol. The comparison results demonstrate bamboo charcoal is a promising adsorbent for furfural removal.
