Abstract
A catalysed filter system for treating particulate-containing exhaust gas from a stationary emission source comprises an elongate filter element comprising porous walls which define a hollow section and a substrate material supporting a catalyst component disposed within the hollow section, the arrangement being such that gas entering the hollow section of the elongate filter element from across the porous walls thereof must contact the substrate material supporting the catalyst component before exiting the hollow section of the elongate filter element.
