PROCESS FOR THE GENERATION OF LOW DEW-POINT OXYGEN-FREE PROTECTIVE ATMOSPHERE FOR THE PERFORMANCE OF THERMAL TREATMENTS

摘要

The present invention provides a first step in which a gaseous hydrocarbon feed and an oxygen-containing oxidant react with a first catalyst to form a reactant, and a second step of adding the reactant to nitrogen contaminated by the presence of oxygen, and The present invention relates to a method for forming a protective nitrogen-based atmosphere for carrying out heat treatment of a metal composed of a third step of transporting to a second catalyst to form a low dew point gas mixture as a protective atmosphere.
