        Cu-ZnO-Cr₂O₃=60:35.6:4.4 gives good yields of MeOH from CO and H₂ at 230°, but is rapidly inactivated.  Cu-ZnO-Cr₂O₃=82:16:2 is stable but gives higher alcohols in addition to MeOH.  Satisfactory results were obtained with a 1:1 mixture of the 2 catalysts, with an initial contact temperature of 200°.
