 1511.    HUFFMAN, J. R., AND DODGE, B. F.  Decomposition of Methanol Over Catalysts Composed of Oxides of Zinc and Chromium.  Ind. Eng. Chem., vol. 21, 1929, pp. 1056-1061; Chem. Abs., vol. 24, 1930, p. 334.

        Parallelism between the decomposition and synthesis of MeOH at 350° over a series of ZnO-Cr₂O₃ catalysts is not complete but is surprisingly good.  Both results show the maximum rate for a catalyst containing 4 Zn:1 Cr.  At about 60% Cr there is a rapid decrease in the activity for decomposition.  From 60-100% Cr, there is very little activity for decomposition into CO and H₂, which is contrary to the results for synthesis.  A steady decrease in the activity of the catalysts for the decomposition, but not for the synthesis, was observed in all cases.  The decomposition over these catalysts was quite complex, the products being CO, H₂, CO₂, CH₄, unsaturated compounds, HCO₂Me, HCHO, Me₂O, and small quantities of unidentified substances.
