                 At the Ètablissements Kuhlmann in Pas-de-Calais gases containing CH₄ are heated with O₂ and steam in the presence of active Ni on a refractory support (the catalytic activity lasts for more than 1 yr.) according to the equations CH₄+0.5 O₂=CO+2H₂ and CH₄+H₂O=CO+3H₂.  Gives other references to coal-hydrogenation processes.
