ABSTRACT:
Apparatus for charging granular catalyst, e.g., cylindrically shaped catalyst, into a multiplicity of elongated reactor tubes is described. The apparatus comprises, in combination, a plurality of contiguously arranged storage hoppers arranged in a bundle and disposed above a substantially horizontal vibratory feeder tray having a plurality of V-shaped open troughs equal in number to the number of storage hoppers. Each trough has a discharge opening at its forward end for delivering the catalyst to a discharge spout affixed to the bottom of the feeder tray and communicating with the discharge opening in the trough. Flexible elongated tubular conduits are attached to each discharge spout and rigid nozzle means attached to the end of each flexible tubular conduit. The nozzle is adapted for insertion into the top of the reactor tube. Electrical vibrating means are mechanically connected to the feeder tray.
In operation, a predetermined quantity of catalyst is charged to each of the storage hoppers. The nozzle attached to the end of each flexible tubular conduit is inserted into the top of a reactor tube and the vibrator activated. Granular catalyst particles travel forwardly along the bottom of the V-shaped trough substantially one particle at a time and are discharged into the flexible tubular conduit and thence into the reactor tube.
