Filtration of nanoparticles by a fluidized-bed adsorption reactor during toluene adsorption

This study investigates the effects of toluene adsorption on the filtration efficiency of nanoparticles by a fluidized-bed adsorption reactor. Simulated flue gas is modified by different types of nanoparticle (SiO₂ and Al₂O₃) with various particle sizes (10 and 80 nm) are also carried out in experiment. Therefore, the experimental results show that the removal efficiencies of the nanoparticles and toluene are in the range of 97% to 87% and 99.8% to 99.4%, respectively. Particularly, BET results show that the particles of 10 nm SiO₂ increase obstruction of the adsorbent volume with increasing toluene content. This finding shows that filtration efficiency increases with the addition of toluene.
