  • the honeycomb unit includes at least inorganic particles, inorganic fibers and/or whiskers.
  • the inorganic particles exemplified are alumina, titania, silica and zirconia; the inorganic fibres exemplified are silica alumina fibres; and the inorganic binders exemplified are silica sol, alumina sol, sepiolite and attapulgite.
  • a catalyst component can be carried on the honeycomb structure.
  • the catalyst component may include at least one type selected among noble metals including platinum, palladium and rhodium, alkali metals such as potassium and sodium, alkaline earth metal e.g. barium and oxides.
  • the honeycomb structure can be used as a catalytic converter e.g. a three-way catalyst or a NO x storage catalyst for conversion of the exhaust gas of vehicles.
  • an oxidation catalyst comprising an extruded solid body and at least one metal with particular application in the field of exhaust gas aftertreatment of internal combustion engine exhaust gas.
  • exhaust gases may result from stationary source emissions, but they have been developed for use in particular for treating mobile sources of emissions, such as passenger cars, trucks and buses.
  • the invention provides an oxidation catalyst comprising an extruded solid body comprising: 10-100% by weight of at least one binder/matrix component; 5-90% by weight of a zeolitic molecular sieve, a non-zeolitic molecular sieve or a mixture of any two or more thereof; and 0-80% by weight optionally stabilised ceria, which catalyst comprising at least one precious metal and optionally at least one non- precious metal, wherein: (i) a majority of the at least one precious metal is located at a surface of the extruded solid body; (ii) the at least one precious metal is carried in one or more coating layer(s) on a surface of the extruded solid body; (iii) at least one metal is present throughout the extruded solid body and is also present in a higher concentration at a surface of the extruded solid body; (iv) at least one metal is present throughout the extruded solid body and is also carried in one or more coating layer(s) on
  • An advantage of the present invention is that by removing catalytic components that are often used in catalytic coatings, the number of coatings can be reduced, e.g. from two layers to one layer; or a single layer can be removed altogether and catalytic metal can be supported on a surface of the extruded solid body as such. This has benefits in reducing backpressure in an exhaust system, increasing the efficiency of the engine.
  • the extruded solid body can be manufactured at higher cell density, increasing strength and decreasing the thickness of cell walls which can improve light off performance and increase activity through mass transfer.
  • On board diagnostics in the context of a motor vehicle is a generic term to describe the self-diagnostic and reporting capability of the vehicle's systems provided by a network of sensors linked to a suitable electronic management system.
  • OBD On board diagnostics

  • the current draft OBD limits for Euro 5: 715/2007/EC for compression ignition (diesel) passenger vehicles are: CO - 1.9 g/km; non-methane hydrocarbons (NMHC) - 0.25 g/km; NO x - 0.54 g/km; PM - 0.05 g/km.
  • Extruded solid bodies according to the present invention generally comprise a unitary structure in the form of a honeycomb having uniform-sized and parallel channels extending from a first end to a second end thereof.

  • Channel walls defining the channels are porous.
  • an external "skin" surrounds a plurality of the channels of the extruded solid body.
  • the extruded solid body can be formed from any desired cross section, such as circular, square or oval. Individual channels in the plurality of channels can be square, triangular, hexagonal, circular etc. Channels at a first, upstream end can be blocked e.g.

  • TSP Shock Parameter
  • the honeycomb structure comprises an assembly of individual honeycomb units cemented together.
  • This, arrangement, also seen in commercially available silicon carbide honeycombs, is designed to avoid catastrophic catalyst substrate failure due to inter alia thermal shock as a result of a relatively high Coefficient of Thermal Expansion (CTE) of the extruded material.
  • CTE Coefficient of Thermal Expansion
  • the manufacture of a honeycomb structure from individual honeycomb units is complicated, laborious, time consuming and expensive and increases the number of possible physical failure modes, e.g. at the cement bonds, compared with a single piece extrusion.
  • a more complete explanation of TSP and CTE can be found in "Catalytic Air Pollution Control - Commercial Technology", Second Edition, R.M. Heck et al, John Wiley & Sons, Inc., New York, 2002 Chapters 7 (in relation to flow through monoliths) and 9 (for wall-flow filters).

  • the latter method comprises the steps of: (i) holding a honeycomb monolith substrate substantially vertically; (ii) introducing a pre-determined volume of the liquid into the substrate via open ends of the channels at a lower end of the substrate; (iii) sealingly retaining the introduced liquid within the substrate; (iv) inverting the substrate containing the retained liquid; and (v) applying a vacuum to open ends of the channels of the substrate at the inverted, lower end of the substrate to draw the liquid along the channels of the substrate.
