Although effective treatment of acid gases such as HCl, SO(x), and NO(x) is essential for preventing air pollution, current methods pose other environmental problems such as CaCl? leaching, reduced landfill lifetimes, and solid waste production. Here we show that acid gases can be treated simply with a Mg-Al oxide slurry. The contribution of Mg-Al oxide to HCl and SO? removal increased as a function of the quantity and temperature of Mg-Al oxide. HCl was removed by the reconstruction of Mg-Al layered double hydroxide (Mg-Al LDH) intercalated with Cl? dissociated from HCl in the slurry. SO? was oxidized into SO? by oxygen in the air flow, dissolved in an aqueous solution, and removed by the reconstruction of Mg-Al LDH intercalated with dissociated SO?²?. Although less pronounced because of surface adsorption, NO was nonetheless removed by Mg-Al oxide. Our results suggest that simultaneous removal of HCl, SO?, and NO using a Mg-Al oxide slurry may be possible without the concomitant problems of conventional treatment methods.
