<p>An apparatus for the control of gaseous and particulate emissions from a gaseous stream containing particulate material, or a gaseous stream without particulate material. The apparatus comprises an inlet and an outlet, and a plurality of cells having walls (260, 265, 270, 275, 280, 285) made of a material permeable to the gaseous stream. The cells are oriented to allow flow (210, 220, 230, 240) of the gaseous stream from the inlet to the outlet, and each of the cells has a first end which is adjacent the inlet of the apparatus, and a second end which is adjacent the outlet of the apparatus. The walls are coated with a catalyst. A barrier (200, 201) is provided at some, but not all, of the second ends of the cells, the barrier comprised of a material that does not allow passage of the gaseous stream.</p> |
