${\text{CH}}_4$ can be prepared by the reaction of  ${\text{H}}_{\text{2}}\text{O}$ with    

Methane can be obtained by hydrolysis of  Beryllium carbide or Aluminium carbide.

${\text{Be}}_{\text{2}}\text{C}+4{\text{H}}_{\text{2}}\text{O}\to 2\text{Be}{\left(\text{OH}\right)}_2+{\text{CH}}_4$

$\text{A}{l}_4{\text{C}}_3+12{\text{H}}_{\text{2}}\text{O}\to 4\text{A}l{\left(\text{OH}\right)}_{\text{3}}+3{\text{CH}}_4$
