An in situ system of filter rejuvenation has a fluid inlet on a first side of a reaction chamber, a fluid outlet disposed on a second side of the reaction chamber, a filtration chamber with a first wall comprising a ceramic glass material with a pass-band in the infrared spectrum. The filtration chamber is in fluid communication with the fluid inlet and the fluid outlet so that a fluid introduced into the inlet passes through the filtration chamber and exits through the fluid outlet. The system has at least one infrared heating element configured to transmit infrared energy within the pass-band of the ceramic glass material to heat the filter medium disposed within the filtration chamber to a temperature of at least 260° C., which can gasify contaminants without combustion.

A method for extending useful life of a sorbent for purifying a gas by sorption of an impurity is provided. The method generating a electrical discharge within the gas to obtain a spectral emission representative of a concentration of the impurity. The method also includes monitoring the concentration of the impurity according to the spectral emission. The method also includes lowering the concentration of the impurity by conversion of at least a portion of the impurity into a secondary impurity having a greater affinity to the sorbent than the impurity. The method also includes comparing the concentration of the impurity to a polluting concentration and managing the sorption of the gas onto the sorbent according to the comparison.

Water is separated into deuterium-depleted water having a low deuterium concentration and deuterium-enriched water having a high deuterium concentration easily and at low cost. A method for separating water into deuterium-depleted water and deuterium-enriched water, the method including: adsorbing water vapor on an adsorbent including a pore body having pores 6 while supplying water vapor to and allowing the water vapor to pass through the adsorbent for a predetermined period of time; recovering deuterium-enriched water containing a large amount of heavy water 8 from the water vapor not adsorbed on the adsorbent; and then recovering deuterium-depleted water containing a large amount of light water 7 from the water vapor adsorbed on the adsorbent.

The present disclosure relates to a carbon-based porous material microscopically exhibiting a three-dimensional cross-linked net-like hierarchical pore structures with micropores nested in mesopores that are in turn nested in macropores. Such material provides for accelerated adsorption and desorption rates and lower desorption temperatures for recovery of organic gas molecules.

A regenerable gas filter includes a housing having in-line an entrance and an exit, a pleated activated carbon fibre sheet or tube, with electrical conductors in the tip of each pleat and further electrical conductors being optionally attached to the ends of said sheet. The conductors are disposed substantially perpendicularly to the gas flow through the housing and the conductors on one side of the pleated sheet are connected to a single central conductor, which in turn was coupled to an electrical DC power source, which is repeated for the conductors on the other side of the pleated sheet. The sheet is stretched over and in electrical contact with the conductors and the pleated sheet or tube is provided with a sealing means to the housing. The regenerable gas filter is used for the purification of air in a Heating, Ventilation and Air Conditioning (HVAC) system.

A method for producing a nanocomposite sorbent comprising carbon nanotube-grafted acrylic acid/acrylamide copolymer which involves copolymerization of acrylic acid and acrylamide in the presence of an aqueous dispersion of carbon nanotubes. The method yields a nanocomposite sorbent material having a reversible adsorption capacity phenol of 5 to 2500 μg of phenol per mg of nanocomposite sorbent. Also disclosed is a method for removing organic pollutants from water using the nanocomposite sorbent.

An activated carbon device for adsorbing solvent from a flow of air is regenerated by feeding heated inert gas to the activated carbon and by applying a reduced pressure to the heated activated carbon.

Various embodiments disclosed relate to sorbents for the oxidation and removal of mercury. The present invention includes removing mercury from a mercury-containing gas using a halide-promoted and optionally ammonium-protected sorbent that can include carbon sorbent, non-carbon sorbent, or a combination thereof.
