A device (1) and a method for producing enameled wires, comprises an application device (3) for applying at least one enamel coating, a furnace (4) for solidifying the enamel coating and an exhaust gas purification device (7) for removing at least nitrogen oxides from an exhaust gas (9) of the furnace (4). The exhaust gas purification device (7) has a unit (13) for the selective catalytic reduction of nitrogen oxides in the exhaust gas (9) of the furnace and a feeding apparatus (11) for feeding a reducing agent, preferably an ammonia-containing compound, in particular a urea solution, into the exhaust gas (9) of the furnace (4). The feeding apparatus (11) has at least one outlet opening, which is designed in such a way that the reducing agent exits from the outlet opening substantially in the flow direction of the exhaust gas (9).

When a product gas producing operation is stopped, a purge operation is executed in which steam purge processing and product gas purge processing are sequentially performed. The steam purge is supplying, instead of a source gas, a product gas from a product gas tank to a reformer using a compressor, and supplying a reformed gas from a reforming processing unit to a plurality of adsorption towers, which perform a pressure swing adsorption operation, while the reformer is heated by a heating burner and steam is supplied to the reformer. The product gas purge is supplying the product gas from the product gas tank to the reformer using the compressor, and supplying the product gas from the reforming processing unit to the plurality of adsorption towers, which perform the pressure swing adsorption operation, while the supply of the steam is stopped and the heating of the reformer is maintained.

Systems and methods for controlling emissions from industrial sources are provided. The system includes an industrial air treatment device that captures emissions from a stack, such as an industrial flare. The industrial air treatment device does not fully encompass or enclose the stack, but allows for ambient air flow with the emissions flow. The industrial air treatment device is separate from and not incorporated into the stack. The industrial air treatment device contains fans to draw in the emissions and air flow, and filters to treat the air flow. At least one of the filters can include a water dispersal system that captures and removes pollutants. The filters can include activated carbon, demister pads, and catalytic converters. The industrial air treatment device releases the treated air to the atmosphere.

The present invention provides a catalyst article for treating exhaust gas comprising: a substrate comprising an inlet end and an outlet end with an axial length L; a first catalytic region comprising support material particles; at least some of the support material particles are rhodium-supporting support material particles having rhodium supported thereon at a concentration of from 0.001 to 3.5 wt. %, based on the weight of the rhodium-supporting support material particle; and the rhodium is present at a loading of up to 20 g/ft.sup.3 relative to the first catalytic region.

An oxidation catalyst for treating an exhaust gas from a diesel engine, which oxidation catalyst comprises: a first washcoat region comprising platinum (Pt), manganese (Mn) and a first support material; a second washcoat region comprising a platinum group metal (PGM) and a second support material; and a substrate having an inlet end and an outlet end; wherein the second washcoat region is arranged to contact the exhaust gas at the outlet end of the substrate and after contact of the exhaust gas with the first washcoat region.

Hydrogen purification devices and their components are disclosed. In some embodiments, the devices may include at least one foil-microscreen assembly disposed between and secured to first and second end frames. The at least one foil-microscreen assembly may include at least one hydrogen-selective membrane and at least one microscreen structure including a non-porous planar sheet having a plurality of apertures forming a plurality of fluid passages. The planar sheet may include generally opposed planar surfaces configured to provide support to the permeate side. The plurality of fluid passages may extend between the opposed surfaces. The at least one hydrogen-selective membrane may be metallurgically bonded to the at least one microscreen structure.

The filter according to the present invention is based on the combined action of two materials: tungsten trioxide (WO3), used for implementing the photocatalytic reactor, and a solution of copper (Cu) nanocluster. In a preferred embodiment of the present invention, these materials are applied to suitable supports (filters), one of a mesh/grid made of metal (or other material, e.g. plastics material) for the photocatalyst and the other of fabric made of cotton (or other hydrophilic material), for sanitizing the fluids by way of the use of said supports in systems for air treatment (devices which take the air from the environment and/or from the exterior, filter it, and reemit it after passage through the filtration system in question) and/or water filtration.

The present invention has high efficiency and is a significant innovation, including on the basis of the efficacy tests performed in the present period of health emergency, including on the infective virus COVID-19.

The present disclosure provides a catalyst for reducing CO and HC which is a core-shell particle including a core and a shell surrounding the core, the core includes metal oxide nanoparticles and noble metal nanoparticles fixed to the metal oxide nanoparticles, and the shell includes zirconia (ZrO.sub.2), and a layer from which the metal oxide is removed between the core and the shell is included.

A process and plant for producing a high purity CO.sub.2 product, comprising: providing a CO.sub.2-rich stream containing hydrocarbons, hydrogen and/or CO, combining it with a stream rich in methane (CH.sub.4), and mixing it with oxygen, thereby forming a CO.sub.2/O.sub.2- mixture; subjecting the CO.sub.2/O.sub.2- mixture to a catalytic oxidation step, thereby producing a purified stream having a higher CO.sub.2 and/or H.sub.2O concentration; removing H.sub.2O from said purified stream, for producing said high purity CO.sub.2 product stream. The CO.sub.2-rich stream is for instance derived from the CO.sub.2-removal section of a plant for producing hydrogen.

An apparatus for collecting a gaseous pollutant from air within a poultry or other concentrated animal feeding enclosure may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air within the poultry enclosure through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.
