Catalyst system for distillation reactor.

摘要

A reaction with distillation structure (11) comprising a plurality of distillation trays (12) and interconnecting catalyst containers (18, 118) which provide a catalytic reaction zone (32) and a primary flow path for descending liquid streams. Catalytic reaction of the liquid streams within the catalyst reaction zone (32) formed in the containers (18, 118) occurs concurrently with fractionation of the reaction products on the distillation trays (12). The containers (18, 118) preferably extend continuously through the reaction zone of the distillation reactor (11) to allow for dump loading and removal of the solid particulate catalyst (20). Structure (144, 146) may also be provided within the containers (18, 118) to influence system hydraulics through the accumulation of liquid within the catalyst bed (32). This is done by providing an open area (147) interiorly of the catalyst bed (32) into which liquid on the distillation and fractionation tray (12) is radially driven. This open area (147) communicates with a liquid accumulation zone (149) wherein liquid accumulates until a sufficient liquid head drives the liquid radially outward for further contact with the catalyst bed (32).
