Abstract
A catalyst support in the shape of a non-planar ring having a bore; wherein there is no rotational symmetry around the axis extending through the center of the bore defined by the ring, and wherein the ratio of the thickness of the ring to the outer diameter of the ring is less than 0.5. The catalyst support shape is especially advantageous to pack within a fixed bed multitubular reactor such as that used for Fischer-Tropsch reactions. The packing of such shapes can reduce the pressure drop across the tubes with little or no difference in the porosity.
