Abstract

A device and method for loading catalyst pellets into reactor tubes of a chemical reactor. A direct mechanical force is applied to one or more pellets where bridging occurs that is different from the forces applied to the surrounding pellets in order to break up the bridge so as to allow catalyst particles to fall through an opening into the reactor tube.
