Abstract:
Systems and methods for cleansing a fluid stream including a support structure positioned generally perpendicular to the fluid stream, the support structure creating an interior space and including a plurality of apertures to allow fluid to flow through the apertures. Also included is at least one expanded sheet positioned within the space, the expanded sheet having a plurality of expanded slits, and a photocatalytic agent coupled to the expanded sheet to oxidize airborne contaminants when exposed to a light source. Pleats may be formed in the expanded sheet to further increase the reactive surface area.
Abstract:
Systems and methods for recovering and purifying water from a gas stream, comprising a gas stream purification unit for purifying the gas stream, a water separation unit for separating water from the purified gas stream, and a water purification unit for purifying the water separated by the water separation unit. The gas stream purification unit may comprise at least one of a soot reactor and a catalytic oxidation reactor, the water separation unit may comprise at least one of a condenser and a water extractor, and the water purification unit may comprise a cyclic reverse osmosis system.
Abstract:
A method of purifying bleed air from an engine heats the bleed air only to an extent necessary for the bleed air to react under catalysis from a noble-metal-based reactor bed, converting the contaminants to filterable form. The contaminants are then removed with a post-treatment filter. A purifier functioning according to the present invention, which heats the bleed air to a temperature no greater than 450null F. which it attains without a combustor, thus releases less heat to adjoining components than a prior-art purifier, and outputs, purified air at a lower temperature than does a prior-art purifier, which typically needs to include a combustor. The purified air is sufficiently-cool as to be suitable for immediate release into interior compartments occupied by humans or the air conditioning system. Contaminants within the exhaust stream may be removed by a reactor bed either within the heat exchanger or separate from the heat exchanger, to produce a purified exhaust gas that may be released to the atmosphere with less environmental impact.
Abstract:
A method for purifying breathing air using a carbon-based monolith structure impregnated with copper, silver, zinc, and molybdenum species and triethylenediamine, wherein the monolith structure is impregnated by a multiple step process. The method of impregnation results in a carbon-based monolith structure that purifies nuclear, biological, or chemical contaminants under conditions of high flow rate and low pressure drop.
Abstract:
The present invention provides a method and system for combined conversion of ozone and organic compounds in airplane bleed air. Catalytic converters have previously been used to reduce the levels of ozone in airplane bleed air. However, these converters have not yet provided an efficient system and method for effectively and simultaneously removing both ozone and organic compounds (including hydrocarbons). The present invention accomplishes the goals of removing both harmful substances by providing a washcoat on a single anodized surface layer, wherein the washcoat may contain an active metal oxide which is active for ozone conversion and may be impregnated with an active metal which is active for hydrocarbon and carbon monoxide conversion. Thus, a single system is disclosed that destroys both ozone and hydrocarbons.
