this is not possible yet..scientists have discovered an enzyme that can convert ethane to methane..however, if u take indirect route ..then its possible..
CH4 + Cl2 = CH3Cl + HCl (in presence of sun light) CH3Cl + Na/ether = CH3-CH3 + NaCl (ethane) this reaction is called wurtz reaction.........

The separation technique commonly used to separate methane from a mixture of methane and ethane is cryogenic distillation. This method exploits the differences in boiling points of the gases; methane has a lower boiling point (-161.5 °C) compared to ethane (-88.6 °C). By cooling the mixture to very low temperatures, methane can be condensed and separated from ethane. This technique is effective for purifying natural gas and other hydrocarbon mixtures.
Out of methane, ethane, propane, and butane, butane has the highest boiling point.

Ethyl bromide can be converted into methane through a Wurtz reaction, where it reacts with metallic sodium in dry ether to form sodium bromide and ethane. The resulting ethane can then be further reduced to form methane using a reducing agent such as zinc powder with concentrated hydrochloric acid. This reaction sequence involves serial substitution and reduction reactions.
Monohalogenation of methane, followed by Wurtz reaction.
It is presumed to be mainly methane and possibly ethane
