Single reformer (methane)


Technology Description

Autothermal reformation is a variation of SMR in which the methane reacts in an O2-deficit atmosphere instead of using high temperature steam, avoiding the need for an external input of heat and, therefore, avoiding the production of a diluted CO2 stream. The process takes place at 800-1150°C.Once the syngas is produced, the rest of the process is like SMR with the difference that the H2/CO ratios are different and the operating and designing conditions of downstream processes must be adapted. CO2 capture above 90% can be achieved by applying capture only to the concentrated process stream.

Relevance for Net Zero

Autothermal methane reforming with CCUS and high capture rates can decrease significantly the CO2 emissions associated with hydrogen production and should play an important role in net zero pathways, particularly for the creation of new production capacities, as long as the CO2 is permamently stored and upstream emissions of the fuel supply are minimised or completely avoided
