  • Patent number: 7985708
    Abstract: A catalyst support is made by coating a metal substrate with a solution containing a precursor for a ceramic and an amphiphilic compound, and treating the coating such that it forms a micelle structure. The coating is then treated to form a mesoporous ceramic coating on the metal substrate. The micelle structure acts as a template, so that the pores are of regular size. The active catalytic material can then be deposited in the pores. The metal substrate may for example be a corrugated foil, which can enable reaction heat to be dissipated from hot spots.

  • Patent number: 7902107
    Abstract: Provided is an emission treatment system and method for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The emission treatment system has an oxidation catalyst upstream of a soot filter coated with a material effective in the Selective Catalytic Reduction (SCR) of NOx by a reductant, e.g., ammonia. Also provided is a method for disposing an SCR catalyst composition on a wall flow monolith that provides adequate catalyst loading, but does not result in unsuitable back pressures in the exhaust.

  • Patent number: 7851403
    Abstract: A honeycomb structure includes adhesive layers and plural honeycomb units bonded to each other by interposing the adhesive layers between the plural honeycomb units. Each of the honeycomb units has partition walls extending along a longitudinal direction of the honeycomb units to define plural through holes. The plural honeycomb units include a SOx absorbent, inorganic particles, and an inorganic binder. An expression Y??0.3X+1.55 (about 1.0?X?about 2.5) is satisfied, in which X represents a content (mol/L) of the SOx absorbent in the partition walls and Y represents a ratio B/A in which A represents a Young's modulus of the honeycomb units and B represents a Young's modulus of the adhesive layers.
