Production of Ambient Gases
The automobiles, electronic products, and various machine tools produced by Japan rank among the top in the world in both quality and quantity.
This is the result of the immense effort that has been put into improving production methods to date, including improving part precision, enhancing durability, and reducing costs.
In particular, it is the result of achieving significant progress in the heat treatment technology for ambient gases in the metal heat treatment industry, and such technology continues to play an important role even today. Metal heat treatment technology involves the heating and cooling in special ambient gases, and controlling the chemical reactions that occur between these materials and gases, which in turn enables processes such as gas carburization, non-oxidative hardening, carbonitriding, and bright annealing.
The gases used in these processes are produced through catalytic cracking with JGC C&C’s catalysts as raw materials of natural gas, propane, butane, ammonia, etc.
JGC C&C’s catalysts have excellent heat resistance, strength, etc., and have been widely used for a long time in the production of ambient gases for metal heat treatment.

- Cracking of ammonia gas is carried out at high temperatures, giving rise to mixed gases of nitrogen and hydrogen.
- These products are used widely, such as in the flame heating of stainless steel to prevent carburization, flame heating of copper and copper alloy, etc.

- Converted gases are produced through the partial oxidation of natural gas, propane, butane, etc. at high temperatures.
- Used widely in gas carburization, bright hardening, annealing, etc.
- To reduce the preprocessing time for catalysts, varieties that have been subjected to reduction and stabilization treatment beforehand are also available.
- Varieties used for low-temperature metamorphism are also available.
