Abstract

<PICT:0659048/III/1> <PICT:0659048/III/2> In a catalytic or adsorption process of contacting a gaseous fluid with a bed of fluidized solids having a ratio of depth to diameter less than 1, supported on a grid having not more than 10 per cent open area, the inflowing stream of gaseous fluid is divided into a number of smaller confined streams with no appreciable pressure drop and discharged at at least three spaced points below the grid at a distance therefrom sufficient to allow for the dissipation of the kinetic energy of the gas before passing through the grid. In Fig. 1 the conventional conical base of a reactor contains an inlet pipe 4 divided into three pipes 5, the ends of which are preferably 1.2 metres below the grid 3. In a preferred embodiment, Fig. 2, the base of the reactor is elliptical and the branched pipes 5 are provided with valves 7.
