Endogas & Exogas

Hardening is a heat treatment process in which the material is heated to a high temperature and then rapidly cooled to alter the metal’s structure and increase its hardness.

In the hardening industry, a protective gas containing CO is required for the surface hardening of steel components in heat treatment furnaces. This gas is produced by the partial oxidation of natural gas with air using the nickel catalyst ReforMax® 117. The catalyst is added to a retort. During the partial oxidation of natural gas, the intermediate products H₂O and CO₂ are initially formed. These then reform unreacted natural gas into a mixture of H₂, CO, and N₂, which also still contains small amounts of CO₂. Overall, this is an endothermically produced gas—in short, “endogas.”
