1. A three-dimensional porous catalyst, catalyst carrier or absorbent structure comprising stacked strands of catalyst, catalyst carrier or absorbent material, composed of adjacent layers of spaced-apart parallel strands, wherein parallel strands within a layer are arranged in groups of two or more closely spaced-apart, equidistant strands separated by a first distance, wherein the groups of equidistant strands are separated from adjacent strands or adjacent groups of strands by a second distance larger than the first distance.
