Abstract
A carbon dioxide (CO) hydrogenation catalyst and a method of its preparation. The COhydrogenation catalyst includes an alkali-metal enriched bauxite residue including calcium carbonate (CaCO), iron(III) oxide (FeO), iron(III) oxyhydroxide (FeO(OH)), aluminum hydroxide (Al(OH)), sodalite, muscovite, and NaAlCSiO. The COhydrogenation catalyst further includes 1 weight percent (wt. %) to 10 wt. % potassium based on a total weight of the COhydrogenation catalyst by inductively coupled plasma optical emission spectroscopy (ICP-OES). The COhydrogenation catalyst is used in a method of hydrogenating carbon dioxide to produce olefins.
