Methane, Hydrogen, Carbide, Organic.
method: In this method, a mixture of carbon monoxide or carbon dioxide and hydrogen is passed over a nickel dust at 300ᵒC — 400ᵒC temperature and as result of this methane is obtained. CO +3H2 ⟶ CH4 + H2O | CO2 + 4H2 ⟶ CH4 + 2H2O Preparation of methane at room temperature: At room temperature, on
