Abstract
A multicellular monolith converter body having a plurality of corrugated thin metal sheets or strips in alternating relation with a thin wire mesh or frame, and which monolith has a cell density up to 100 cells per square inch. These monoliths are useful under conditions where back-pressure is a critical factor, e.g., natural draft exhaust applications. These devices may have corrugated thin metal sheets coated with a refractory metal oxide, e.g., alumina, with or without a noble metal catalyst.
Claims14
A multicellular monolith converter body comprising a stack of (a) a plurality of corrugated thin metal sheets in alternating contiguous relation with (b) a plurality of discrete thin metal wire mesh, screen, ribbon or frame elements, each metal sheet from (a) and each thin wire mesh, screen, ribbon or frame element of (b) together defining a plurality of cells, and having a cell density of less than 100 cells per square inch.
A multicellular monolith converter body comprising (a) a peripheral metal frame surrounding a stack of (b) a plurality of corrugated thin metal sheets in alternating contiguous relaton with (c) a plurality of discrete thin metal wire mesh, screen, ribbon, or frame, said thin wire mesh, screen, ribbon or frame having a void fraction or open area of at least about 95%, elements (b) and (c) defining cells and having a cell density of less than 100 cells per square inch.
