Abstract
The invention relates to an extrusion die for the manufacture of monolithic adsorption tubes having a solid body portion with a multiplicity of tunnels for the passage of gas. The die comprises a multiplicity of rods positioned within an outer cylindrical housing and oriented parallel thereto. The rods are supported near the entrance end of the housing, by at least two sets of ribs, each set of ribs arranged in a geometric pattern and oriented perpendicular to the cylindrical housing. The rods provide the form for tunnels in the extruded monolithic adsorption tube.
