 1734.    ---------------.  [KEMMER, H.]  [Removal of Carbon Monoxide From City Gas.]  Angew. Chem., vol. 49, 1936, pp. 133-137; Chem. Abs., vol. 30, 1936, p. 3204.

        This is a description of a 2-stage process whereby a partial oxidation of the CO with steam over a Cr catalyst takes place, followed by a hydrogenation of the remaining 4-5% of CO to CH₄.  This last reduction proceeds virtually quantitatively at 200°-250° over a Ni-Th catalyst by utilizing the H₂ formed in the first step.  The 2-stage process should not cost more than 0.5 pf. per m.³  To eliminate the existing difficulties of gas purification and to lower the working costs, it is proposed to combine the process with the synthetic production of fuel by the Fischer-Tropsch process.
