Direct route from ethanol to pure hydrogen through .

2018-1-15 · The schematic representation of a fluidized bed membrane reactor is shown in Fig. 1.The inlet gases, EtOH/H 2 O/air, are fed to the bottom part of the reactor through a 40 micron porous plate distributor. All the EtOH is partly oxidized with O 2 and decomposed into other gases (reaction (1)), while the produced CH 4 and CO start to react with H 2 O (reactions (2–4)).
