ABSTRACT:
In an apparatus for contacting fluid with subdivided contact material, such as a radial-flow catalytic reactor, means having a substantially horizontal surface is attached to a lower portion of a vertically movable member within the reactor, the member being selected from center pipes and particle-retaining screens. The weight of contact material on the means restrains upward movement of the member during temperature cycling, and thus prevents problems caused by the upward movement.
