The present invention relates a method of preparing methane using γ-valerolactone. A solution of γ-valerolactone is mixed with a triruthenium dodecacarbonyl catalyst, for a reaction at 150° C.-250° C. for 1 to 12 hours, and then subjected to cooling; wherein a mass ratio of γ-valerolactone to the triruthenium dodecacarbonyl catalyst is between 1:2 and 1:50; and the solution of γ-valerolactone has a mass concentration of 50 g/L-300 g/L. In the present invention, γ-valerolactone is converted into methane rapidly by a one-step catalysis deoxygenation using a triruthenium dodecacarbonyl catalyst. The preparation method provided by the present invention can realize a complete conversion of γ-valerolactone, and the methane gas has a yield up to 45 wt %. Besides, such method has characteristics of short reaction time, high yield of methane, easy collection, simple process and convenient operation, and it has industrialized application prospect.
