Metal Monoliths for Air Pollution Control
Applied Catalysts manufactures a wide variety of ABATE VOC™ metal monolith supported catalysts. The metallic catalyst substrates are made of a thin, specialty alloy metal foil called FeCrAlloy. The foil is assembled, flat and corrugated alternating side by side, to form a honeycomb structure. Similar to ceramic monoliths, the assembled foils form cells or parallel channels that allow exhaust gases to run axially through the catalyst. Monoliths are sometimes called flow-through substrates. Exhaust gases flowing through the cells contact the catalyst surface which has been coated onto the cell walls. The advantages of metal monoliths are their high geometric surface area and low pressure drop associated with the thin cell walls. Depending on the application, the foils in metal monoliths can be brazed/welded together, or steam oxidized to provide good mechanical durability and resistance to thermal shock.
Metal monoliths can be provided in several cell geometries to meet your particular design requirements, including but not limited to 16, 25, 50, 100, 200, 230, 300, 400, 500, 600 and even 700 cpsi (cells per square inch). The substrates can be formed into round parts of diameters up to 48, or formed into rectangular or square Cans of any dimension using SS framing.
Depending on your application, Applied Catalysts can also use VersaGrid™ ceramic monoliths for your catalyst needs.
