Beschreibung
Zusammenfassung:	A methanol synthesis catalyst containing 20-50 wt% cupric oxide, 15-60 wt% zinc oxide, 5-35 wt% alumina or chromia and 0.2-7.0 wt. The manganese oxide is prepared by calcining fine precipitates obtained by addition of sodium hydroxide or carbonate to aqueous solutions of the metal nitrates at an elevated temperature to give a pH of 8-9, where at least two components are coprecipitated, and manganese is introduced either by coprecipitation of its nitrate or by subsequently impregnating the calcined precipitate.
