Synthesis of alcohols from carbon oxides and hydrogen. V. Catalyticbehaviour of pure Cr, Zn, Mn oxides towards CO/H2

Abstract Pure oxides of Mn, Zn and Cr have been prepared and characterized. Their catalytic behaviour in the direct synthesis of higher alcohols from CO and H2 has been studied in terms of the elementary reactions: formation of methanol, chain growth to higher alcohols, direct water-gas shift reaction, methanation, formation of heavier hydrocarbons. The results provide useful references when analyzing catalysts with more complex formulations.
