Abstract
Abstract The reactor for performing heterogeneous catalyzed chemical reactions comprises packing elements which are constructed of corrugated plates having inclined corrugations and catalyst members which are disposed between the plates. In one embodiment, the catalyst members have alternating fluted parts and unfluted parts with the fluted parts disposed within the troughs of the adjacent corrugated plate. In other embodiments, the catalyst members may be in the form of unfluted members, continuously fluted members and members which are disposed in planes between pairs of corrugated plates or within the troughs of the corrugated plates.
