It is important to treat gaseous HCl from incineration streams efficiently to avoid adverse environmental consequences. In this paper, a new treatment method for gaseous HCl is presented-the application of Mg-Al layered double hydroxide (LDH) intercalated with CO32- (CO3·Mg-Al LDH) to treat gaseous HCl continuously. The degree of HCl removal without water vapor is higher than that with water vapor; further, this reaction does not require H2O. In addition, the degree of HCl removal increases with increasing temperature, CO3·Mg-Al LDH quantity, HCl concentration, and improved contact between CO3·Mg-Al LDH and HCl gas. The treatment of HCl gas by CO3·Mg-Al LDH leads to the production of Mg-Al LDH intercalated with Cl-. Further, HCl is also absorbed on the surface of CO3·Mg-Al LDH. Our proposed treatment method works effectively for the treatment of gaseous HCl from incinerator streams.
