A catalytic reactor includes: a reaction-side flow channel in which a reaction fluid flows; structured catalysts accommodated in the reaction-side flow channel. Each structured catalyst includes inclined surfaces in at least part of each of two surfaces facing other structured catalysts. The inclined surfaces are inclined in the same direction with respect to an arrangement direction of the structured catalysts.

A cross-corrugated structured packing element is provided for use in mass transfer or heat exchange columns. The packing element has a plurality of packing layers positioned in an upright, parallel relationship to each other and including corrugations formed of alternating peaks and valleys and corrugation sidewalls extending between the peaks and valleys. The packing element also includes a plurality of apertures each presenting an open area. The apertures are distributed such that the corrugation sidewalls have a greater density of open areas than any density of the open areas that may be present in the peaks and valleys. Some of the apertures may be present in the peaks and the valleys to facilitate liquid distribution. The apertures may also be placed in rows or other patterns that are aligned in a direction along a longitudinal length of the corrugations. Regions with a larger apex radius may be formed in the peaks, such as by depressing spaced-apart segments of the peaks to form spacers in the undepressed portions of the peaks. Some of the apertures may be positioned in the transitions from the depressed portions of the peaks to the unmodified apex sections.

The present invention relates to a packing element for a structured packing including at least two adjacent corrugated sheets, wherein each of the corrugated sheets has a plurality of alternately oriented peaks and troughs, wherein adjacent corrugated sheets are oriented such that the corrugations of the adjacent corrugated sheets intersect in crisscross fashion with the corrugations of the corrugated sheets extending obliquely relative to the vertical direction, wherein each corrugated sheet contacts each of the adjacent corrugated sheets at points of intersection between the corrugations of the corrugated sheet and those of the adjacent corrugated sheets, wherein all corrugated sheets are tied together by means of at least one rod, wherein the at least one rod penetrates the corrugated sheets perpendicularly to the longitudinal section of the corrugated sheets, wherein on the at least one rod before the first corrugated sheet of the packing element and/or after the last corrugated sheet of the packing element at least one mounting clip is provided for fixing the corrugated sheets on the rod, wherein the mounting clip has a central part forming a coupling portion for coupling the mounting clip to the rod and two opposing lateral parts forming a clamping portion for a clamping engagement with the corrugated sheet, wherein the lateral parts are connected with the central part and angled with respect to the central part.

A contactor for a heat and/or material exchange column includes an arrangement of two structured packings developing different geometric surface areas and having parallel principal directions. A heat exchange column, a floating structure including such a contactor, and the use of a column equipped with such a contactor are also disclosed.
