        CO is converted into CH₄ by conducting CO over a mixture of CaO and Ca(OH)₂ at about 400°.  The reaction takes place with the intermediate formation of Ca formate, which decomposes to give CH₄ and C₂H₄.  This salt at 360°-370° gives a gas containing 20% CO₂, 27% CO, 51% H₂, and 2% hydrocarbons.
