Abstract
A catalyst particularly useful in the production of methanol can be made by preparing a solution of copper and zinc nitrates, the ratio of copper to zinc being from 1:1 to 8:1 and then precipitating the copper and zinc by the addition of ammonium carbonate or ammonium bicarbonate. After the precipitated material has been agglomerated and calcined, a copper oxide-zinc oxide catalyst, low in sodium and sulfur is obtained.
