        Catalyst 60 Cu:35.6 ZnO:4.4 Cr2O3 is very active, but it rapidly loses activity when it works above 200°.  If the pressure is 40-30 atm., yields of 0.51-0.63 l. of MeOH per hr. per kg. of catalyst are obtained, and the catalyst retains its activity.  At higher pressures, larger yields are obtained but catalytic activity drops.  The ratio of CO:H2 can be varied greatly without effect on the process.
