                  With an unsupported Zn-Cu-Al catalyst, a gas mixture of 27% CO₂, 71% H₂, and 2% N₂ at 325° and 1,700 lb. pressure gave an effluent gas containing 4% CO.  This suggests that the primary step in the synthesis of MeOH from CO₂—H₂ involves the reduction of CO₂ and the nature of the catalyst determines the extent to which the resultant CO is hydrogenated.  As the activity of the catalyst decreases the MeOH reaction is most affected; experiments with this same catalyst and water gas gave appreciable amounts of CO₂.  This suggests a new mechanism for the synthesis of MeOH, which will be discussed later.
