Removal the Coal Ash, NO, and SO2 Simultaneously by the Fluidized-Bed Catalyst Reactor

This study investigates the potential of utilizing a fluidized-bed catalytic reactor for the simultaneous removal of NO, SO2, and coal ash from simulated flue gas. The operational conditions for the evaluation include the operating parameters of catalytic filtration and the effects of simultaneous catalytic filtration through a fluidized-bed reactor. The use of the catalyst of CuO/AC shows that the simultaneous catalytic/filtration for of NO, SO2, and coal ash were 46%, 81%, and 87%, respectively. Results from the analysis of fresh and reacted catalyst indicate that the degradation temperature (T-d) point decreased with increased operating temperature and gas velocity by fluidized-bed reactor. Moreover, BET and FE-SEM results show that the coal ash particles could obstruct the catalyst surface area and pore volume.
