Endogas & Exogas

The production of endogas and exogas with nickel catalyst is widely used in heat treatment and metallurgical processes to create controlled protective atmospheres. In retort systems, the nickel catalyst ReforMax® 117 RR enables reliable gas generation with consistent composition, supporting stable furnace operation and repeatable material results.

Endogas is generated from LPG, propane, or natural gas through controlled incomplete combustion over a nickel catalyst. The resulting gas mixture of hydrogen, nitrogen, and carbon monoxide acts as a reducing atmosphere that protects metal surfaces from oxidation. This controlled environment supports precise adjustment of microstructure and helps optimize hardness, strength, and ductility.

Exogas is produced as a defined mixture of hydrogen, nitrogen, carbon monoxide, and carbon dioxide with very low oxygen content. With adjustable hydrogen levels, exogas provides a safe and effective protective gas for manufacturing and heat treatment applications. ReforMax® 117 RR supports efficient and dependable exogas generation.
