Multiple-stage stacked reactor system for moving bed catalyst particles

Abstract

Abstract A PLURALITY OF SUPERPOSED REACTOR SECTIONS, WITH EACH HAVING AN ANNULAR-FORM CATALYST SECTION, ARE PROVIDED WITHIN A PARTITIONED VERTICALLY ELONGATED CHAMBER SUCH THAT CATALYST PARTICLES CAN READILY MOVE BY GRAVITY FROM THE UPPER SECTION DOWN THROUGH THE LOWERMOST SECTION. UNIFORMLY SPACED APART SMALL DIAMETER CATALYST TRANSFER CONDUITS PROVIDE FOR THE DOWNWARD MOVEMENT OF CATALYST INTO AND OUT OF THE CHAMBER, AS WELL AS BETWEEN ADJACENT SECTIONS IN A MANNER TO SUBSTANTIALLY PRECLUDE REACTANT STREAM FLOW BETWEEN REACTOR SECTIONS THROUGH SUCH CONDUITS. ALSO, A PREFERRED CONSTRUCTION UTILIZES SPECIAL FLAT FACED, WEDGE-WIRE, TO FORM THE SCREENING FOR RETAINING THE CATALYST IN THE ANNULAR-FORM CATALYST ZONES AND THE FLATFACED WIRED FORMING THE SCREENING ARE POSITIONED VERTICALLY SUCH THAT DOWNWARDLY MOVING CATALYST WILL NOT HAVE TO RUB OVER A ROUGH SURFACE AND BE SUBJECTED TO ATTRITION.
