Johnson Matthey manufactures durable SINOx® plate SCR catalyst for high NOx reduction in high-dust applications. Plate SCR catalyst consists of a catalytically active materials rolled onto stainless steel mesh plates. The plates are crimped and stacked into sturdy element frames which are then installed in steel modules. This construction results in a catalyst with very high mechanical strength and resistance to the abrasive dusts that are found in some exhaust streams.
