Abstract

A device for mixing and distributing two gases upstream of the catalytic zone of a reactor by producing a homogeneous mixture and a profile of velocities which are as flat as possible. The device uses a plurality of internal chambers (I) enclosed in an external chamber (II), the external chamber communicating with each of the internal chambers via orifices pierced in the wall of said internal chambers (I) at a well-defined height. The external chamber (II) is provided with a perforated plate placed at a distance H2 from the inlet pipe for said chamber (II). The device is applied to the inlet of an autothermal reactor.
