     Repetition of Berthelot’s experiment in which C3H6 was formed when 1 vol. CO and 2 vol. CH4 were conducted through a glowing glass tube filled with pumice, yielded the same phenomenon.  It was impossible to identify the hydrocarbon on account of the small quantity obtained.  In another experiment, the same mixture of CH4 and CO was conducted over various catalysts at different temperatures.  CO was decomposed with formation of CO2, CH4 dissociated partly into C and H2, but a reaction between CH4 and CO was scarcely detectable.  When the waste gas from a catalyst for the synthesis of mineral oil was conducted over metallic sponge Fe at 900°, the greatest part of the CO2 was reduced to CO; gasol, heavy hydrocarbons, and a fraction of H2 disappeared, and a large quantity of H2O was formed.
