A method for simultaneously distributing catalyst particles across the full diameter of catalyst bed with a single rotor is disclosed. The bed has substantially uniform high density by forming a multiplicity of annular rings of catalyst concentric with the vessel or bed center. Such action is achieved without varying rotor speed by deflecting catalyst from a feed hopper into a plurality of arcuate sectors or portions of different radial lengths on a rotating disk-like member. Preferably, each arcuate portion has a volume proportional to one of the annular areas of the bed within the cross-sectional area of the vessel. The desired volume is formed by the radial length of the arcuate sector, its included angle on the disk, and the height of the vanes separating adjacent sectors. The volume is maintained by flow of catalyst into the sectors at a rate to maintain such volumes full at the constant speed of rotation of the disk-like member so that each annular ring is simultaneously formed across the bed with minimum overlap.
A method of loading catalyst particles into as large diameter reactor vessel to provide substantially uniform packing density to each of a multiplicity of adjacent annular areas across the full cross-sectional area of a bed of catalyst within the vessel, which comprises the steps of:
