Abstract
L'invention concerne la production des gaz industriels. Le procédé proposé d'obtention d'un mélange gazeux azote-hydrogène, par conversion à haute température d'hydrocarbures gazeux avec un coefficient d'excès d'air inférieur à l'unité, et séparation subséquente du produit final, est caractérisé en ce qu'on réalise la conversion des hydrocarbures gazeux dans un lit de matière réfractaire granulée 4 inerte au point de vue catalytique, à une température de 1 400 à 1 800 degrés C. Le mélange gazeux obtenu trouve des applications comme milieu protecteur et réducteur dans les industries du verre, dans la métallurgie, etc.
