ABSTRACT:
A process and device for charging a plurality of tubes in a tube reactor with granular solids, preferably with catalysts, which, for this purpose, are fed from one or more stock vessels to a controllable metering device and from there, via guiding and directing devices and flexible hose connections, successively into the tubes to be filled, wherein, during the packing of the tubes, a stream of gas of constant amount is generated, which can, after an individual tube has been packed, be passed temporarily, via one or more controllable valves, through this packed tube, a pressure drop measurement being carried out at the same time and the differential between the measured value and the predetermined intended value being used to determine a small additional amount of packing material which is subsequently introduced into the tube which has been subjected to measurement, and wherein thereafter a program control triggers the mechanical packing of the next tube, metered in the same manner, with subsequent pressure drop measurement and metering of the additional amount.
