Fuel processing system (steam reforming)

Return to the process flow of the fuel processing system

This componet converts methane into hydrogen.

Principles

Methane is converted into H2 and CO2 (partly CO) by making methane and steam react on a catalyst (Ni-based or Ru-based).

 

Steam reforming reaction

 
 
 
Conventional catalyst
  • Utilizing Ni catalyst the risk of carbon deposition exists under low S/C (*) conditions as well as relatively shorter durability.

* The molar ratio between the added steam and the carbon contained in the hydrocarbon, is referred to as the S/C (steam to carbon) ratio.

Osaka Gas's unique reforming catalyst
  • Even if the S/C ratio is low, highly-efficient steam reforming is possible without risks of carbon deposition.
  • This makes it possible to secure long-term durability and to eliminate the need to replace the catalyst for 90,000 hours. In addition, by optimizing the quantity of the noble metal, catalyst cost has been reduced.
