Abstract: Ho Honeycomb monolith structure, especially for use in mass transfer-limited processes or processes for the selective catalytic reduction (SCR) of nitrogen oxides, comprising: a plurality of cell walls defining a plurality of polygonal channels, the plurality of cell walls and channels extending in parallel along a common direction from an entrance end to an outlet end of the structure in the fluid flow direction. The transversal cross section of a polygonal channel has the shape of a convex elongated polygon, wherein at least 50% of the internal angles between two adjacent walls of the convex polygon are above 90 degrees and wherein the cell diameter ratio LL/LS is greater than 1.5.
