Abstract, 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 disc. 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 both the radial length of the arcuate sector …
