Abstract: A catalytic reactor is provided for the decomposition of ozone in air. The reactor comprises a core structure (10) having an inlet end effective for receiving a flow of ozone-containing air and an outlet end effective for discharging the ozone-containing air therefrom. The core structure is made of a catalytically-active metal alloy which is effective for decomposing at least a portion of the ozone present in the air as the ozone-containing air flows between the inlet end and outlet end of the core structure. The catalytically-active alloy comprises a silver-containing metal alloy and may comprise an alloy having silver and copper as the principle constituents. The catalytically-active alloy may optionally be thermally activated for use in low temperature applications. The core structure may be configured so as to provide a plurality of tortuous flowpaths between the inlet and outlet ends of the core structure to promote turbulent flow of the ozone-containing air.

Abstract: An environmental control system for use in a transportation machine, with the system being effective for receiving and conditioning a heated, ozone-containing airstream prior to delivering the airstream to a habitable space within the machine. The system comprises a catalytic reactor (74) including a housing and a core structure disposed within a generally cylindrical portion of the housing. The core structure is made of a catalytically-active metal alloy which is effective for decomposing at least a portion of the ozone present in the air as the ozone-containing air flows between the inlet end and outlet end of the core structure. The catalictically-active metal alloy comprises a silver-containing metal alloy and may comprise an alloy having silver and copper as the principle constituents. The catalytically-active metal alloy may optionally be thermally activated for use in low temperature applications. The core structure is brazed to the housing of the reactor and may comprise a plurality of fin assemblies, each configured as an annular ring, which are generally concentrically disposed relative to one another about an axially extending centerline axis of the reactor, and with each of the fin assemblies being brazed to radially adjacent ones of the fin assemblies so as to prevent nesting between radially adjacent pairs of the fin assemblies. The system may further include at leat one heat exchanger disposed downstream of the catalytic reactor for the purpose of cooling the airsteam discharging from the reactor prior to delivering the airstream to the habitable space of the machine.

Abstract: An environment control system (10, Fig. 2) for use in a transportation machine. The system is effective for receiving and conditioning a heated airstream (16, Fig. 2) containing organic compounds and ozone, prior to delivering the airstream to a habitable space within the machine. The system includes a dual bed reactor having an upstream portion (46, Fig. 2) which is effective for converting organic compounds within the airstream into carbon dioxide and water, and a downstream portion (48, Fig. 2) which is effective for decomposing ozone within the airstream. Both the upstream and downstream portions of the core structure include at least one fin assembly (114, Fig. 8). Each portion may include a plurality of the fin assemblies, configured as annular rings and generally concentrically disposed relative to one another. Alternatively, each portion of the reactor may comprise a single fin assembly which is wrapped upon itself in a spiral configuration. Radially adjacent ones of the fin assemblies of each portion, or radially adjacent spirals of the individual fin assembly of each portion, are brazed to one another so as to prevent nesting between radially adjacent ones of the fin assemblies or spirals. Each fin assembly of the upstream portion is anodized, with a catalyst which is effective for converting organic compounds into carbon dioxide and water being disposed on and within the resulting anodized surface layer. Each fin assembly of the downstream portion may be similarly anodized, with application of a catalyst effective for decomposing ozone, or alternatively, each fin assembly of the downstream portion may be constructed from a catalytically-active metal alloy.
