Biofuel purification: Coupling experimental and theoretical investigations for efficient separation of phenol from aromatics by zeolites

Résumé

The purification of second-generation biofuels is becoming an urgent issue due to the toxicity of the combustion products of residual phenol in these biofuels. The use of solid sorbents such as zeolites appears as a promising solution for ensuring the selective sorption of phenol towards aromatics (the main components of biofuel). In the present work, we have adopted a bottom-up approach for removing phenol from a synthetic biofuel feed containing isooctane, phenol (1 wt.%), n-nonane (1 wt.%) and toluene (40 wt.%), using faujasite-type Y zeolites with Si/Al ratio = 2.5. The astonishing performance of HY zeolite to treat the synthetic biofuel has been highlighted by assessing the interaction modes of the molecules involved over the structural sites via the combination of theoretical molecular modeling and experimental adsorption experiments.
