1486585 Packing for material contact DEUTSCHE GOLD-UND SILBER SCHEIDEANSTALT 17 Sept 1974 40431/74 Headings B1F and B1R [Also in Division F4] Apparatus for heat exchange and/or contact between gases and/or liquids and/or solid particles comprises a column having a plurality of layers of prismatic hollow bodies centrally constructed both internally and externally and open at opposing ends wherein the hollow bodies are arranged in each layer with their open ends adjacent the preceeding and succeeding layers, whereby in each layer a plurality of discrete flow paths through the hollow bodies is surrounded by a continuous jacket zone outside the hollow bodies, and wherein successive layers of hollow bodies are offset relative to one another so that the discrete flow paths of one layer communicates with the jacket zone of the following layer and vica versa, resulting in the formation of two separate systems of flow paths, the jacket zones may contain displaceable bodies. The bodies may be catalytic or coated with catalyst. Thus, in Fig. 2, material flowing down through body 14 passes into the jacket zone surrounding bodies 12 and then passes through body 13. The bodies may have cross sections as shown in Fig. 3C.
