Single Step Electrified Hydrogen Production from Methane in a Gliding Arc/fluidized Bed Reactor

In this work, a plasma fluidized bed reactor has been studied as an electrified methane decomposition reactor for sustainable hydrogen production. A combined 3D rotating gliding arc/fluidized bed reactor assembly demonstrates a stable operation with a CH4/Ar mixture containing up to 8 vol% of CH4. The reactor provides a 97.2 % H2 selectivity at a methane conversion of 16.6 % and energy costs of 10.6 kJ L− 1 . This performance provides a new benchmark for electrified H2 production with a potential to utilise renewable electricity. In addition, carbon materials are produced. The characterizations show difference in the morphology of the materials collected in different reactor zones.
