Abstract
Catalyst elements are shaped to provide large surface area per unit of volume (porosity), while providing high packing density. Generally, the elements are characterized by more than six faces of identical size and shape, and by members extending outwardly in three dimensions. Each element includes a plurality of concave regions defined by the intersection of various of their planar surfaces, yet is not simply a section of an extrusion.
