ABSTRACT:
A vessel arrangement and process for contacting a fluid reactant with a particulate catalyst in a plurality of flow channels and discharging fluid and particles from the flow channels. The particles are discharged axially from the bottom of the flow channels into an unconfined bed of particles. Fluid is discharged in a transverse direction through the sides of the flow channels and across screen openings located a short distance above the channel outlets. A plurality of chambers, additional particulate material or baffles regulate fluid flow through sections of the screens and prevent excessive fluid velocity in any section from holding up particle flow through the flow channels. The reactor arrangement and process of this invention is a particularly useful for arrangements that may be used to operate a reactor under isothermal or other controlled temperature conditions where a heat transfer fluid surrounds a plurality of tubular conduits or multiple flow channels that confine the particles and fluid.
