 1731.    KEMMER, H.  [Removal of CO From Illuminating Gas.]  Gas- u. Wasserfach, vol. 72, 1929, pp. 744-751; Chem. Abs., vol. 23, 1929, p. 4799.

       Catalytic processes may be used, such as the hydrogenation of the CO by passing the gas over a catalyst composed of active C impregnated with Ni containing about 18% ThO₂.  A CO:H₂ ratio of 1:5 is required for quantitative conversion to CH₄.  The Ni catalyst is strongly activated by the ThO₂ so that the reaction temperature can be kept low.  The optimum temperature for CH₄ formation lies between 180°-190°.  It is mentioned that with these catalysts in addition to CH₄ quite small amounts of heavy hydrocarbons would be formed.
