ABSTRACT:
A system to make walls for catalyst baskets for heterogeneous synthesis reactors, particularly the distribution walls which are inserted in axial reactors in order to modify them into substantially radial (or axial-radial) reactors with low energy consumptions. The distribution walls are divided into n sections. By attaching each section end to a device consisting of two flange elements, the radially longer one protruding over the distribution wall, the invention achieves truing and stiffening of the entire device. The other end extends slightly into the inside of the catalyst bed. Between the internal walls of the basket and the perforated distribution sheet, an airspace is formed by using separating rods or, in their absence, using a perforated bridge plate as the distribution wall.
