ABSTRACT:
An improved apparatus for distributing particulate material, e.g., comprising catalyst particles, over a zone, e.g., chemical reaction zone, wherein the apparatus is not centrally located with respect to the zone, comprising:
A supply hopper, having inlet means and outlet means, for holding particulate material;
A deflection plate located adjacent to the end of the outlet means away from the supply hopper to deflect the direction of at least a portion of the particulate material flowing through the outlet means;
At least two conduits in fluid communication with at least one source of gaseous media, each of the conduits being situated such that at least a portion of the gaseous media from the conduits flows in the space between the end of the outlet means away from the supply hopper and the deflection plate to thereby cause at least a portion of the particulate material to be propelled in substantially the same direction as the flow, provided that the gaseous media is expelled from at least two of the conduits at different, predetermined flowrates so that the particulate material is substantially uniformly distributed over the zone.
An improved method for distributing particulate material in a zone has also been discovered.
