- the free height H ⁇ which remains between the outlet of the mixing device 26 and the upper surface 72 of the bed allows the homogeneous mixture to increase its homogeneity.
- the mixture has an average concentration deviation of less than 3%, preferably less than 2%.
- the synthesis gas CO + H 2 passes through the lower thermal barrier layer 68 and is withdrawn at the outlet 14 of the reactor.
