Reactor And Reactor Unit With Hollow Fibers

This invention relates to a reactor unit with a first chamber and a second chamber, wherein the first chamber is formed by the interior of a housing and wherein the second chamber is formed by the interior of a plurality of hollow fibers arranged in the housing. The hollow fibers are arranged in the housing such that their density in at least one region of the first chamber does not exceed 10 fibers/mm2, based on the cross-sectional area of the first chamber. In accordance with another aspect of the invention it is provided that in the reactor unit two casting compounds are arranged, in which a portion of the hollow fibers is embedded and between which another portion of the hollow fibers extends, wherein the length of at least some or all hollow fibers is at least 0.5% greater than the distance of the casting compounds.
