walls for catalytic beds of radial or axial-radial flow reactors

摘要

radial or axial-radial flow catalytic chemical reactor comprising a cylindrical shell (2) and at least one catalytic bed (5) and comprising a plurality of perforated tubes (10), said tubes having an open end (11) in communication with an inlet (3) of a gaseous flow of reactants into the reactor (2), the tubes being provided with a plurality of holes (14) on their side surface, the tubes (10) being disposed around the catalytic bed (6) which limits the catalytic bed and which distributes the reagents within the bed; each of the tubes being formed by longitudinal or helical butt welding of a perforated strip (15).
