Abstract
A distributor assembly for a multi-bed, downflow catalytic reactor is disclosed. The distributor assembly is configured for disposal and fixable attachment between the inner surfaces of the walls of a multi-bed downflow cylindrical reactor wall and for disposal between vertically stacked catalyst beds within the reactor. The assembly includes: PA1 (a) a collection plate configured for substantially horizontal disposal between the walls of a cylindrical reactor; PA1 (b) a plurality of generally arc-shaped elongated baffles disposed in a staggered, substantially symmetrical pattern about the collection plate; PA1 (c) a first mixing zone configured to be bounded on the bottom by the collection plate, on one side by a wall of a cylindrical reactor, and on the opposite side by the outer surface of the elongated baffles; PA1 (d) a cylindrical weir fixably attached to the collection plate about the outlet; PA1 (e) a second mixing zone bounded on the bottom by the collection plate, on one side by the outer surface of the cap and the first cylindrical weir, and on the opposite side by the inner surface of the elongated baffles; PA1 (f) a cap disposed over and about the first cylindrical wei…
