     Synthesis was carried out in the presence of 4ZnO.  Cr2O2 catalyst was prepared from 324.0 parts ZnO and 304.0 parts Cr3O3 by shaking in 5 l. of H2O for 24 hr.  The mass then was filtered through a Büchner funnel and pressed into long strips.  The gas was a technical water gas containing varying amounts of H2 and CO.  Therefore H2 was added to the required ratio.  The process was carried out at a constant pressure, the best pressure being 250 atm., and 370°.  The product was contaminated with Fe carbonyl, which precipitated out through the influence of air.  The degree of conversion with each cycle amounted to about 9%, with a total yield of 63%.
