Abstract
A device is presented for use as a centerpipe in a radial flow reactor, or for a radial flow adsorption bed. The device includes a plurality of stacked slotted cylindrical sections and frustums. The design retains the particles in a solid particulate bed that can be flowing through the reactor. The frustums provide covers to the cylindrical sections to prevent the flow of solid particles back through the slots in the cylindrical sections.
