Document Type and Number:
WIPO Patent Application WO/2011/066489
Kind Code:
A3
Abstract:
A method is disclosed of forming a honeycomb extrusion body mixer comprising providing a honeycomb extrusion body (20) having multiple cells (22) extending along a common direction from a first end of the body (20) to a second end and separated by cell walls (30); forming one or more apertures (36), through respective cell walls (30) between one or more respective pairs of said multiple cells such that each aperture (36) has an aperture width measured perpendicular to the common direction (D) of 90% or less of a cell wall width of the respective cell wall (30) measured perpendicular to the common direction (D); and plugging the respective pair of cells at one side of the respective associated aperture (36). Mechanical machining processes, laser machining, or chemical machining may be used, desirably on a green state honeycomb extrusion body (20). The apertures (36) are desirably formed through machining at or through one or both end faces of the honeycomb body (20). Machining through a side of the body (20) is an alternative.
