Abstract: The invention concerns materials for eliminating oxides of nitrogen NO and NO2 present in exhaust gases, in particular from the internal combustion engines of automotive vehicles operating in a medium which is super-stoichiometric in oxidising agents, which can adsorb oxides of nitrogen then desorb the oxides of nitrogen by elevating the temperature with respect to the adsorption temperature or by passage of a rich mixture, said materials comprising mixed oxides the metals of which are in octahedral coordination, with the octahedra connecting together so that the structure generates lamellae. Said materials adsorb oxides of nitrogen by insertion and do not become poisoned in contact with oxides of sulphur and carbon contained in the gases. In the presence of a group VIII metal, said materials are capable of eliminating oxides of nitrogen adsorbed by reduction during the passage of a rich mixture.

Abstract: Sorbent components containing calcium, alumina, and silica are used in combination during coal combustion to produce environmental benefits. Sorbents are added to the coal ahead of combustion and/or are added into the flame or downstream of the flame, preferably at minimum temperatures to assure complete formation of the refractory structures that result in various advantages of the methods. When used together, the components reduce emissions of elemental and oxidized mercury; increase the level of Hg, As, Pb, and/or Cl in the coal ash; decrease the levels of leachable heavy metals (such as Hg) in the ash, preferably to levels below the detectable limits; and make a highly cementitious ash product.
Abstract: A method for preparing radioactive-substance adsorbent depositing on a carriable structure is revealed. The method uses a supercritical fluid to mix a first solution with a carrier. The first solution includes an extractant dissolved in a first solvent. By low surface tension and high permeability of the supercritical fluid, the extractant in the first solution deposit evenly on the carrier so as to form an adsorbent. Thus the adsorbent formed provides better adsorptivity for the radioactive substances.

Abstract: Using zeolites as the active adsorbent, adsorbent laminates have been fabricated with various sheet supports. These adsorbent laminates have been successfully operated for oxygen enrichment at high PSA cycle frequencies, such as upwards of at least 150 cycles per minute. Methods for making suitable adsorbent laminates are described. The methods generally involve forming a slurry comprising a liquid suspending agent, an adsorbent and a binder. Laminates are made by applying the slurry to support material or admixing support material with the slurry. The slurry can be applied to support material using a variety of techniques, including roll coaters, split roll coaters, electrophoretic deposition, etc. One method for making laminates by mixing support material with the adsorbent slurry comprises depositing the slurry onto a foraminous wire, draining the slurry material, and pressing the material to form a ceramic adsorbent paper. Spacers can be formed on adsorbent laminates to space one laminate from another.

Abstract: The present invention discloses a method and an apparatus for reactivating lime-based sorbents and increasing the carbon dioxide-capture capacity of the sorbent in the combustion of carbon-containing fuels. The method of the present invention seeks to increase the carbon dioxide capture capacity of lime-based sorbents by applying concentrated or 100% carbon dioxide directly to a lime-based sorbent. Optionally, the lime-based sorbent may be pretreated using a hydration process after each process of carbon dioxide separation. The regenerated sorbent is carbonated in a presence of concentrated carbon dioxide and elevated temperatures. The invention is useful in reducing the need to add additional sorbent to maintain the carbonation/calcination cycle. The regenerative potential of the sorbent as manifested by the present invention leads to increased carbon dioxide-capture capacity of the sorbent.

Abstract: An agglomerate for use in economical bulk treatment of contaminated sediments with minimal environmental impact is formed from a sorbent, bentonite clay and sand. The agglomerate has sufficient density so as to sink through a water column into sediment below the water column and is still sufficiently light as to be capable of mixing with the sediment when subjected only to bioturbation. The agglomerate can be formed into pellets and applied to a water column over contaminated sediment by broadcast methods, so as to permit economical remediation of contaminated sediment with negligible environmental impact.
