Process flow

• Steam reforming
  City gas is reformed to H₂-based synthesis gas using high-performance steam reforming catalysts that were independently developed by Osaka Gas.
  
  
• Hydrogen recovery by pressure swing adsorption (PSA)
  Using adsorbents with excellent H₂ separation properties, impurity gases are removed from the synthesis gas, and only high-purity H₂ is delivered.
