Abstract

A reactor has a reactor unit with a first chamber and a second chamber, with the first chamber being formed by the interior of a housing and the second chamber being 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. The reactor unit can include two casting compounds, in which a portion of the hollow fibers are embedded and between which another portion of the hollow fibers extends. The length of at least some or all of the hollow fibers is at least 0.5% greater than the distance of the casting compounds.
