A catalytic distillation packing that has continuous smooth channels over its entire length is used to change out catalyst in a catalyst distillation arrangement without replacement of packing units and long turnaround times. The long, continuous channels are formed from perforated, corrugated plates that have a sufficient thickness to maintain the geometry of the channels and permit free catalyst flow for catalyst change out. The thickness of the plates also eliminates the need for complicated bracing and attachment arrangements that adds to the expense of the packing arrangement and can obstruct the movement of catalyst therethrough. The long, continuous channels are used with an inlet arrangement that provides ready adjustment of the number of channels that are filled with catalyst and channels that are free of catalyst. It is also possible in this arrangement to operate with a channel arrangement wherein all channels are filled with catalyst.

[ What is claimed is:] [1.]1. A catalytic distillation column comprising:a structured packing comprising a plurality of corrugated plates having perforations defined therein and placed parallel to each other;a vapor outlet defined by vapor openings in the top of said packing and a liquid outlet defined by liquid openings in the bottom of said packing;a plurality of channels defined by spaces between said corrugated plates and extending continuously from said vapor outlet to said liquid outlet, wherein said corrugated plates extend continuously over the height of said channels and at least a first portion of said channels are adapted to retain a particulate catalyst and a second portion of said channels are adapted for the flow of liquid and vapor; opposite ends of said corrugated plates defining said first portion of said channels being spaced apart to define catalyst inlets and catalyst outlets; and opposite ends of said corrugated plates defining said second portion of said channels being spaced apart to define said vapor openings adjacent to said catalyst inlets and said liquid openings adjacent to said catalyst outlets;means for selectively releasing and retaining catalyst at the bottom of said first portion of said channels for removal of the catalyst from the catalytic distillation column without the necessity of removing the packing from the column;means for adding catalyst to the top of said first portion of the channels;means for collecting vapor from said vapor outlet; andmeans for collecting liquid from said liquid outlet.
