    摘要: The invention relates to a filtration and predistribution device (4) comprising: a flat plate (5) perforated by holes, each hole being overhung by a vertical hollow duct (6) that includes at least one slot passing through the lateral wall thereof, a filtration bed (7) placed on the plate surrounding said ducts, comprising at least one layer of hollow filtering elements (8) that are larger in size than the slots of the ducts, said filtering element being obtained by winding, in touching and/or non-touching turns, a wire of cross section (s) so as to have at least one closed end and having a [free area (Sfree) of the element/area (Sm) occupied by the wire] ratio of between 2 and 50%. The invention also relates to the use of this device (4) for filtering and predistributing at least one particle-laden liquid upstream of a fixed catalytic bed (12) of a reactor.

    摘要: Packed bed reactors that have a series of alternating layers of packing. A first packing layer has open body packing elements randomly packed in a layer up to about 10 packing elements deep; and a second packing layer has porous support elements of hydrophobic foam. The porous support elements are randomly packed up to about 10 porous support elements deep. Further, the packing elements of the first layer include substantially cylindrical shapes and the porous support elements of the second layer include substantially rectilinear shapes. In some embodiments, the second layer supports microbial organisms in a biological reactor, and the first layer of open body packing provides fluid flow spaces to facilitate fluid flow and distribution, mass transfer, and to minimize channeling.

    摘要: A new tower packing element intended for randomly dumped packed beds. The new tower packing consists essentially of at least two substantially straight legs which are attached tangentially to the ends of an arcuately bent surface. The straight legs contain slots. Tongues either associated with the slots or independent of the slots point away from these substantially straight legs. The arcuately bent portion is free of slots and tongues.
