description | Use of a large pore molecular sieve incorporating a d pi -donor guest material and having a pore diameter greater than about 4-Angstroms as agent for the non-catalytic sorptive decontamination of a non- pi -acceptor gas or gaseous mixture comprising pi -acceptor gas-phase pollutant. Preferred guest materials include Cu and Ag. The methods, compositions and devices of the invention are applicable to the decontamination of a range of non- pi acceptor gases or gaseous mixtures such as air, oxygen, nitrogen, carbon dioxide, hydrogen, the inert gases, saturated hydrocarbon gases, and mixtures thereof, and containing a range of pi -acceptor gas phase pollutants such as carbon monoxide, oxides of nitrogen, oxides of sulfur, ethylene, and mixtures thereof.
L'invention porte sur l'utilisation d'un crible moléculaire à pores larges de plus d'environ 4 ANGSTROM de diamètre incorporant un matériau hôte donneur d pi servant à la décontamination non catalytique par sorption de gaz non pi accepteurs ou de mélanges de gaz comprenant des polluants pi accepteurs en phase gazeuse. Les matériaux hôtes préférés sont le Cu et l'Ag. Les procédés, compositions et dispositifs de l'invention s'appliquent à la décontamination d'une série de gaz non pi accepteurs ou de mélanges gazeux tels que O, N, CO2, H, les gaz inertes, les hydrocarbures gazeux saturés, ou leurs mélanges, qui contiennent différents polluants pi accepteurs en phase gazeuse, tels que le CO, des oxydes de N, des oxydes de soufre, de l'éthylène ou leurs mélanges. |
