ABSTRACT
In the present work, CuO-based sorbent materials supported on tonsil and bentonite were prepared and evaluated for flue gas desulfurization using thermogravimetry. Results were compared to sorbents supported on commercial alumina, zirconia and titania. Application of ultrasonic energy during preparation of sorbent materials was evaluated, and their sorption capacity, as well as their activation energy, were improved. Sorbent materials supported on tonsil have similar SO2 retention than those supported on alumina, and the latter is the most commercial sorbent material for dry flue gas desulfurization. A modified shrinking core model was adapted to simulate the experimental results, and the kinetics parameters were estimated by performing a non-linear regression analysis. All sorbent materials were active at 300-500 ?C for flue gas desulfurization.
