  • Patent number: 4169879
    Abstract: The reactor is traversed by a central tube with an essentially radial circulation of the gases or other fluids. Said cylindrical part of the solids bed is surmounted by a substantially hemispherical reaction zone permeable to said gases or other fluids. The hemispherical part of the reactive zone is comprised between two substantially hemispherical caps one of which surmounts the central tube and the other bounds the upper periphery of this zone with the pressure drop undergone by the gases or other fluids passing through the hemispherical zone being greater than that undergone by the gases or other fluids passing through the cylindrical zone and therefore the perforations of the hemispherical part of the central tube are calculated to compensate for this difference and equalize the flow of gases or other fluids in the whole of the solids mass.
