Deactivation mechanisms of Cu–Zn–Al <sub>2</sub> O <sub>3</sub> in CO <sub>2</sub> hydrogenation induced by SO <sub>2</sub> exposure
SO 2 in CO 2 -rich gases inhibits CO 2 hydrogenation over industrial Cu–ZnO–Al 2 O 3 , causing irreversible deactivation through surface adsorption of sulfates and sulfites, as well as phase transitions to Cu 2 S, CuS, and ZnS.
