| abstract | 272,864. Commercial Solvents Corporation, (Assignees of Woodruff, J. C., and Bloomfield, G.). June 21, 1926, [Convention date]. Methanol.-For the synthesis of methanol by the catalytic interaction of carbon oxides and hydrogen at elevated temperature and pressure, catalysts are employed which comprise a mixture of metal oxides non-reducible under the conditions of the synthesis to which a metallic halide is added. Preferably the non-reducible oxides are those, of metals of the second periodic group to which an oxide of a metal of the third to seventh groups is added as a promoter, whilst the amount of halide used is less than one chemical equivalent of the amount of the principal oxide present. Catalyst mixtures specified are zinc oxide-chromium oxide-zinc chloride or vanadium chloride, zinc oxide-manganese oxide or vanadium oxide-magnesium chloride, magnesium oxide - vanadium oxide - magnesium fluoride, magnesium oxide-chromium oxidechromium chloride, strontium oxide-chromium oxide-zinc chloride. Examples of the preparation of the catalysts are given, and in the case of each catalyst, the yield of methanol under specified reaction conditions is stated. Specification 227, 147 is referred to. The Specification, as open to inspection under Sect. 91 (3 (a), refers to the use of a catalyst comprising a single non-reducible metal oxide and a metallic halide. This subject-matter does not appear in the Specification as accepted, |
