A method for preparing a ceramic composition while simultaneously reducing the quantity of carbon dioxide from municipal solid waste that would discharge into environment includes decomposing the municipal solid waste to generate a carbon dioxide-water vapor mixture, providing a matrix, the matrix containing a reactant; and contacting the carbon dioxide-water vapor mixture with the matrix to promote a reaction between the carbon dioxide of the carbon dioxide-water vapor mixture and the reactant of the matrix. The reaction forms a product, thereby producing the ceramic composition.

The disclosure provides devices, methods, and systems for treating reactive metals and other reactive species produced during operation of thermal solid-state gas generators. Thermal energy, which may be derived from the gas generation process, physical contact with the evolved gases, or a dedicated or shared heat source, is used to release a gaseous species that neutralizes the reactive species. In some embodiments, the neutralization reaction causes the release of additional product gas(es).

A system for removing methane oxidation catalyst (MOC) poisons from an exhaust gas including a methane abatement unit that may receive the exhaust gas having methane (CH.sub.4)and the MOC poisons. The methane abatement unit includes a guard bed that may remove the MOC poisons from the exhaust gas and may generate an intermediate exhaust gas having the CH.sub.4 and devoid of the MOC poisons. The guard bed includes a MOC poisons capturing component having a first transition metal oxide, an aluminum oxide (Al.sub.2O.sub.3) support material, and a dolomite-derived support material. The methane abatement unit also includes a MOC bed fluidly coupled to and positioned downstream from the guard bed. The MOC bed includes a MOC and may remove CH.sub.4 from the intermediate exhaust gas to generate a treated exhaust gas having less than approximately 200 parts per million volume (ppmv) CH.sub.4.

A system may include a chamber with a main sub-chamber and a first porous membrane separating a first sub-chamber from the main sub-chamber. The system may include a fluid in the chamber and an input directing inflow into main sub-chamber proximate an entry end of the chamber. The system may include a first output permitting outflow from the first sub-chamber proximate an exit end of the chamber wherein a molecule entering at the entry end must traverse a length of the chamber to exit at the exit end.

An efficient low-energy carbon dioxide removal system comprises an automated air mover equipped with sensing devices to measure flow rate, volume, level, pressure, temperature and concentration. Packing materials and air-liquid distributors are used in a multi-stage catalytic reactor. The multi-stage catalytic reactor processes ambient air and generates pure carbon dioxide gas and generates exhausted gas released to ambient air. In operation, air contacts the base solution in the presence of a catalyst via the air mover, distributor, and packing materials. The air reacts with the base solution thereby generating a base solution having carbon dioxide and generating exhaust (absorption reaction). Next, the exhaust is released from the reactor. Next, a catalyst is added, heat is applied to the base solution having carbon dioxide thereby generating carbon dioxide and generating a base solution without carbon dioxide (desorption reaction).

A system and method for providing inerting gas to a protected space is disclosed. The system includes an air separation module that includes an air inlet, a membrane with a permeability differential between oxygen and nitrogen, a nitrogen-enriched air outlet, and an oxygen-enriched air outlet. The system also includes an air flow path between an air source and the air separation module inlet, and an inerting gas flow path between the air separation module nitrogen-enriched air outlet and the protected space.

A process for capture of carbon dioxide comprising the steps of contacting the carbon dioxide with at least one metal carbonate in an aqueous organic solvent at a predetermined temperature.

The present disclosure relates to an apparatus, system and method for selectively capturing a carbon-containing gas from an input gas mixture.

The present invention discloses an industrial solid waste incinerator and flue gas treatment apparatus, comprising a water-cooled feed hopper, a water-cooled grate and a chamber which are connected in sequence. A front arch, a rear arch and side walls which are formed of membrane water-cooled walls, are provided between the water-cooled grate and the chamber, and a dechlorination tower is arranged behind the chamber. Two sets of rear secondary air pipes, which comprise an upper set of rear secondary air pipes and a lower set of rear secondary air pipes, are arranged on the rear arch, and a dry desulfurization device is arranged between the two sets of rear secondary air pipes, so that the reaction medium and the flue gas are sufficiently disturbed and mixed, and stroke is extended.
