Abstract: A device for feeding large-grained catalyst into reactor tubes comprises a storage vessel and internal guide plates to reduce it to a hopper-type cross section; just below the narrow outlet, there is a pair of revolving, elastic-faced rolls, the roll gap(s) of which forms a passage for the material into a hopper below; this hopper has an outlet pipe which fits into the top of a reactor tube. The area of the rectangular opening formed by the guide plates is equal to or less than (the roll length) times (axial length of a roll). For filling several tubes several of these devices can be combined into one unit, with a line of rolls on a common shaft all driven from one motor and transmission unit. A defined quantity of catalyst is fed into each tube, fairly rapidly and without damaging the catalyst. Arching inside the tube is prevented.
