ABSTRACT:
The invention relates to a process for preparing a heat treatment atmosphere by a catalytic reaction in a catalytic reactor (16) between a first gas mixture (12) containing oxygen and a second gas mixture (26) containing a hydrocarbon, characterized in that the catalytic reactor is arranged in substantially vertical position and in that the reaction mixtures are introduced into the catalytic reactor through the bottom (19) of the reactor with recovery of the heat treatment atmosphere resulting from the reaction at the top (20) of the reactor.
