摘要： A process for the removal of nitrous oxide from a gas stream having a contaminating concentration of nitrous oxide to provide a gas stream with a significantly reduced concentration of nitrous oxide is described. The process includes the use of a process system having multiple N2O decomposition reactors each of which contain a nitrous oxide decomposition catalyst and heat transfer units each of which contain a heat sink media that are operatively connected in a particular order and arrangement for use in the process. The gas stream is passed to the process system that is operated for a period of time in a specific operating mode followed by the stopping of such operation and reversal of the process flow. These steps may be repeatedly taken in order to provide for an enhanced energy recovery efficiency for a given nitrous oxide destruction removal efficiency.

摘要： Waste treatment comprises heating it in a chamber to effect pyrolysis of the waste, introducing oxygen into the chamber to effect combustion of the pyrolyzed waste, and contacting off-gas from the pyrolysis and/or combustion steps with an oxidation catalyst to convert carbon monoxide and hydrocarbons in the off-gas into carbon dioxide and water and with a reduction catalyst to convert nitrous oxides to nitrogen and oxygen. Thus, domestic waste is treated in a batch process using catalytic converters to reduce the level of toxic components before off-gas reaches the atmosphere.

摘要： A catalytic converter apparatus for use in an exhaust system of an internal combustion engine includes a housing having a gas inlet and a gas outlet, and at least one catalytic substrate element disposed in the housing. The at least one substrate element is divided into a plurality of zones or sections, the zones at least partially separated from one another to inhibit heat flow. The zones can be at least partially separated with walls. The walls can include insulating material for reducing the mobility of heat radially outwardly. Each of the zones defines a generally separate flow passage connecting the inlet and outlet in fluid communication. The apparatus can heat more rapidly from a cold start compared with conventional catalytic converters.

摘要： In an exhaust gas treatment, the amount of a highly corrosive mercury-halogenating agent to be added is reduced with the mercury-removing efficiency maintained high.A mercury-halogenating agent (40) and ammonia (30) are added to combustion exhaust gas from a boiler, the exhaust gas containing NOx, SOx and mercury. The exhaust gas is brought into contact with a CO/HC oxidation catalyst (50) and is then subjected to reduction denitration (60) in the presence of a solid catalyst. Thereafter, metallic mercury is oxidized to halogenated mercury. Then, the exhaust gas is wet-desulfurized (100) with the alkaline absorbing solution, and the halogenated mercury is removed.

摘要： This invention is an emission control system wherein the boiler hosts a reactor which contains one or more catalysts for the purpose of reducing NOx and/or CO in the emissions. The reactor containing the NOx/CO catalysts may be placed at a place where the temperature is in the range of 300-1000° F. The hot flue gas can be diverted using control dampers and blended with colder flue gas inside the boiler to achieve the desired flue gas temperature for the selected catalyst. NOx is removed by the SCR catalyst inside the boiler upon injecting a suitable reducing agent (e.g. ammonia, or hydrocarbons). The CO and NOx catalysts may be used in any order. The emission control system is an integral part of the boiler, and the existing capabilities of the boiler to recover the heat from flue gas, after the catalyst layers, is utilized such that the overall boiler efficiency remains high.

摘要： Hot flue or process gases are cleaned utilizing an apparatus containing a barrier filter module formed of a monolithic ceramic support structure coated with a thin porous ceramic layer having a pore size of about 0.04-0.5 microns, and a catalyst module formed of a support structure coated with catalyst. The hot flue gases may be associated with a fluidized bed boiler plant, such as a circulating fluidized bed reactor. Gases to be cleaned are passed through the barrier filter module into contact with the thin porous ceramic layer, and then through the catalyst module so that there is a catalytic reaction with the gas.
