Autothermal reforming (ATR) for hydrogen production with carbon capture and storage (CCS)

Autothermal reforming (ATR) is the combination of both partial oxidation (POX) and steam methane reforming (SMR) in one reactor operating at 900-1150 degrees Celcius with energy efficiency lower than that of SMR. The typical reaction is given by the following equation:

CH₄+H₂0/2+O₂/4 <-> CO + 5H₂/2

The described ATR plant includes a carbon capture and storage (CCS) component.
