ABSTRACT:
The process and system according to the present invention are used for the production of an atmosphere. The process involves feeding an impure nitrogen stream, combined with a hydrocarbon to a catalytic reactor having a non-noble metal catalyst to produce a gas which is suitable for use as an atmosphere in furnaces for thermal treatment of metals. The impure nitrogen stream, contains less than 21% oxygen and is preferably produced by a gas membrane system. The system for producing the atmosphere preferably includes a membrane separator, one or more heat exchangers and a catalytic reactor preferably having a nickel catalyst on an alumina support.
