A catalytic reactor according to an embodiment includes a catalytic unit including at least one catalyst having a honeycomb structure in which a plurality of passages extending in an axial direction are formed, a reactor housing accommodating the catalytic unit, and a seal plate sealing between an outer periphery of the catalytic unit and an inner periphery of the reactor housing. The seal plate seals between the outer periphery of the catalytic unit and the inner periphery of the reactor housing at an upstream end portion of the catalytic unit with respect to a flow of a fluid flowing in the reactor housing.

A reactor for accommodating high contaminant feedstocks includes a reactor vessel having an inlet for introducing a feedstock containing contaminants into an interior of the reactor vessel. A basket is located within the reactor vessel interior and contains a particulate material for removing contaminants from the feedstock to form a purified feedstock that is discharged to a purified feedstock outlet. A catalyst is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.

The invention includes a reactor installation device comprising a flexible band, a first tab, a second tab, and a mechanical stop. The flexible band has a first end, a second end, a top edge and a bottom edge. The first tab is attached at or near the first end, the second tab is attached at or near the second end, and the both tabs are attached at or near the top edge of the flexible band. The mechanical stop is attached to the flexible band, the first tab, and/or the second tab, between the top edge and the bottom edge of the flexible band. The flexible band is capable of being bent into the shape of a circle by bringing the first and second tabs into contact. The invention also includes a method of inserting a skirt seal into a stackable structural reactor using the reactor installation device.

A support structure for a structured catalytic packing is disclosed. The support structure is in a fixed position relative to the reactor tube containing it. It supports catalyzed casings that are free to move relative to the support structure. The support structure and casings are inserted in the reactor tube such that the support structure is located proximate the longitudinal axis of the tube and the casings are located between the support structure and the reactor tube wall. The support structure comprises a central support tube or rod proximate to, and impervious or perforated discs perpendicular to, the longitudinal axis of the reactor tube, and may comprise spacers separating the discs.

The invention relates to a fluid collection device (8), in particular a support collector unit, for collecting fluid flowing through a packing (4) of a material exchange column (1). The fluid collection device (8) includes a support ring (11), a plurality of support profiles (12-16) secured to the support ring (11) for supporting the at least one packing (4), and a plurality of collection channels (19-21) secured to the support ring (11) for collecting the fluid. The collection channels (19-21) are positioned in parallel to the support profiles (12-16) and the support profiles (12-16) are arranged in such a way that they are each arranged in a no-flow area (40, 41) of one of the collection channels (19-21).

The invention relates to a packing assembly for a material exchange column, comprising at least one structured packing plate and a container in which the at least one structured packing plate is arranged. The at least one structured packing plate has packing packets. Each packing packet has interconnected packing sheets. The packing sheets are corrugated and have corrugation peaks and corrugation valleys. Adjacent packing sheets contact each other at the corrugation peaks. Additional corrugated packing sheets are added between the packing packets such that the at least one packing plate is pretensioned against the container in a radial direction thereof. Both the corrugated packing sheets of the packing packets as well as the additional corrugated packing sheet added between the packing packets are arranged solely on a common preferred plane or parallel thereto.

A structured packing element has the shape of a rectangular flat plate, and is provided with slots and recesses. The slots are intended for assembly by interlocking the structured packing elements together in order to form the structured packing. The recesses are provided in order to form channels within the structured packing. A packing structure can be obtained by assembling such packing elements. Such a packing can be used for an operation of bringing a gas and a catalyst into contact. A manufacturing process of such a structured packing is also disclosed.
