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.
