        Mixture of CO and H₂ (3:1) is passed through a reaction tube at 300°-320° and 180-200 atm. in contact with a catalyst containing Fe₂O₃, K₂CO₃, and ZrO₂.  Fractionation of the product yields an alcohol fraction equal to 25 gm. per m.³ of gas and containing 60-70% of EtOH.  The reaction tube of 120 mm. diameter produces 1,500 kg. of EtOH per month.
