Abstract
An apparatus for feeding a granular catalyst to a destination such as a reactor at a constant feeding rate uniformly charges the catalyst material into the device. The granular catalyst is loaded into individual compartments of a hopper and is ejected at a discharge rate controlled by a gate. When a vibrator is activated, a trough is caused to vibrate in its obliquely upward direction and the granular material in the trough is smoothly conveyed toward outlets of granular material passages formed in the trough, and is introduced to reaction tubes of the reactor via sieves. Powdery waste of the granular catalyst produced by the vibration of the trough is removed by letting it fall the sieves made in the granular material passages.
