摘要： A catalytic converter for cleaning exhaust gas from an internal combustion engine, in particular a diesel engine or a lean-burn engine, includes at least one honeycomb body coated with catalytically active material and having passages through which the exhaust gas can flow, walls separating the passages from each other, and first and second zones disposed in succession in a flow direction. The first zone has a lower thermal capacity per unit of volume of the honeycomb body than the second zone and the second zone has a thermal capacity of at least 800 joules per liter and Kelvin [J/lK], preferably at least 900. Sheet metal layers in the first zone preferably have an average uncoated thickness of less than 0.06 mm, preferably less than 0.04 mm. Sheet metal layers in the second zone preferably have an average uncoated thickness of more than 0.06 mm, preferably more than 0.08 mm and in particular 0.11 mm. In that way, the first zone can rapidly reach its operating temperature at high exhaust gas temperatures while the second zone stores heat for operating conditions involving a low exhaust gas temperature.

摘要： A method and apparatus for purifying air to deactivate toxic chemical and biological species such as Sarin, mustard gas, phosgene, cyanogen chloride, Anthrax spores, E. coli bacteria, Salmonella bacteria, Hepatitis virus, and Norwalk virus. The apparatus comprises a reaction chamber coupled to a counterflow heat exchanger. Incoming contaminated air is directed through a heating side of a counterflow heat exchanger to preheat it. The air is further heated to a temperature of at least 200° C., which is sufficient to deactivate common biological toxic species. Optionally, the reaction chamber may include a catalyst on a surface area over which the heated air is directed, which enables a thermocatalytic reaction that is particularly effective in deactivating biological and chemical warfare agents, such as anthrax and Sarin. Portable embodiments of the invention are useful in both military and civilian air purifying applications, while fixed installation of the apparatus are useful in deactivating toxic species from the air in areas where food is prepared or stored, or in purifying air in the environment of a living space.

摘要： The present invention discloses a fine particle-removing device connected to an exhaust path for a combustion exhaust gas, for removing fine particles contained in the exhaust gas. The apparatus has filter units, a fuel injection nozzle and an ignition device. The filter units are made of porous ceramic partitions that form a plurality of narrow paths extending in the flowing direction of the exhaust gas. The porous ceramic partitions capture the fine particles contained in the exhaust gas when the exhaust gas is introduced into one side and exhausted from the other side of each path. The fuel injection nozzle injects a fuel into exhaust gas intake portions of the filter units to burn the fine particles captured on the porous ceramic partitions.

摘要： An effluent gas stream treatment system for treatment of gaseous effluents such as waste gases from semiconductor manufacturing operations. The effluent gas stream treatment system comprises an oxidation unit to which an oxygen-containing gas such as ozone may be added, with input of energy (e.g., thermal, radio frequency, electrical, microwave, etc.), to effect oxidation of oxidizable species in the effluent, such as halocompounds (e.g., chlorofluorocarbons, perfluorocarbons), CO, NF3, nitrogen oxides, and sulfur oxides). The effluent gas stream treatment system may include a wet scrubber associated with the oxygen-containing gas source, so that the gas stream is contacted with the oxygen-containing gas during the wet scrubbing operation, to enhance removal of oxidizable species in the gas stream during treatment.

摘要： A method for removing combustible, metallurgical dust out of the exhaust gas from installations for drawing single silicon crystals is provided. The dust contaminated exhaust gas and a reactive gas, such as air, oxygen or ozone, are fed into a reactor operated at a temperature of 50 to 500° C. where the reactive gas combusts the dust to form solid products. The reactor may be equipped with a catalyst, such as nickel, palladium or platinum, to promote the reaction. The solid products-containing exhaust gas is passed through a filter. By combusting the dust in the reactor, spontaneous explosions can be minimized.
