Abstract
A catalyst loading system for utilizing catalyst from a bulk supply located adjacent but not on the upper tube sheet of a catalytic reactor and for mechanized measuring of multiple identical quantities of catalyst and for mechanized loading of catalyst pellets into the reaction tubes of the reactor to achieve even drop rate, compaction and outage of the reaction tubes. From the bulk supply, multi-compartment catalyst charging hoppers are individually filled in rapid and accurately measured fashion by mechanized filling equipment having a predetermined sequence of operation that ensures accuracy of volumetric catalyst measurement. The charging hoppers are used for delivery of measured volumes of catalyst of a reactor tube loading mechanism which may take the form of a mobile cart framework being selectively positionable relative to the upper tube sheet and reaction tubes of a catalytic reactor to be charged with catalyst pellets. A pair of electronic vibrators are mounted to the cart framework and provide for support and vibratory movement of a vibratory tray having a catalyst feed hopper adapted to feed catalyst pellets to a plurality of generally parallel catalyst transfer troughs…
