A catalyzed particulate filter includes at least one inflow channel including one end where a fluid inflows and another end that is blocked and extends in a length direction, at least one outflow channel including one end that is blocked and another end where the fluid outflows, and the other end extends in the length direction, at least one porous wall defining a boundary between the inflow channel and the outflow channel neighboring each other and extending in the length direction, and a catalyzed supporting member disposed on an inside of the outflow channel, wherein the supporting member includes a plurality of balls.

The present invention addresses the problem and purpose of providing a honeycomb structure that has a sufficiently high strength and is excellent in endurance, and a catalyst for cleaning an exhaust gas using the same that is excellent in resistance to sulfur oxide (SOX). The honeycomb structure of the present invention is one consists of a flat inorganic fiber sheet comprising an inorganic fiber sheet having supported thereon an inorganic binder and zeolite, and a corrugated inorganic fiber sheet comprising an inorganic fiber sheet having supported thereon the same inorganic binder and zeolite, which are alternately combined with each other, wherein it is characterized in that the zeolite has a particle diameter (i.e., a median particle diameter, D50) of from 0.5 to 10.0 m.

A diesel soot filter includes a substrate having a surface disposed at least partially within a fluid path of the diesel soot filter. A glass catalyst is disposed on the surface of the substrate such that an exhaust gas contacts at least a portion of a surface of the glass catalyst as the exhaust gas moves within the diesel soot filter. The glass catalyst comprises a plurality of alkali metal ions disposed within the glass catalyst and releasable to the surface of the glass catalyst at a controlled rate and the alkali metal ions combust with the soot as the exhaust gas travels along the fluid path. An oxide basis of the glass catalyst comprises Silicon (Si), Potassium (K), Cesium (Ce), and Zirconium (Zr)

An exhaust trap configured to filter an exhaust stream of a vacuum furnace may include a housing and a media barrier. The housing defines an interior. The media barrier may divide the interior of the housing into a first chamber and a second chamber and is configured to allow the exhaust stream to flow from the first chamber to the second chamber. The exhaust trap may further include a filter medium in the first chamber and configured to filter the exhaust stream. No filter medium is present in the second chamber.
