Abstract

An improved apparatus for distributing particulate material, e.g., comprising catalyst particles, over a zone, e.g., chemical reaction zone, comprising: A supply hopper, having an inlet and an outlet, for holding particulate material; A deflection plate located adajcent to the end of the outlet away from said supply hopper to deflect the direction of at least a portion of the particulate material flowing through the outlet; and At least one conduit in fluid communication with at least one source of gaseous media, the conduit being situated such that at least a portion of the gaseous media from the conduit flow in the space between the end of the outlet 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. An improved method for placing particulate material in a zone has also been discovered.

Dependent claims

Apparatus for distributing particulate material over a zone comprising:

a supply hopper, having inlet means and outlet means, for holding particulate material;
a deflection plate located adjacent to and below the end of said outlet means away from said supply hopper to deflect the direction of at least a portion of said particulate material flowing through said outlet means, provided that the cross-sectional area of said deflection plate is larger than the cross-sectional area of the end of said outlet means away from said supply hopper and that said deflection plate extends beyond the vertical projection of said outlet means in substantially all directions;
and
a plurality of conduits in fluid communication with at least one source of gaseous media through which gaseous media is caused to flow, said conduits extending into and terminating in the space between said outlet means and said deflection plate to thereby cause at least a portion of said particulate material to be propelled in a plurality of directions beyond said deflection plate.
