GIS-TYPE ZEOLITE Russian patent published in 2021 - IPC C01B39/46 B01J20/18 B01J20/28

Abstract RU 2752404 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a GIS-type zeolite, an adsorbent material containing a GIS type zeolite, and a method for separating one or several components. The GIS-type zeolite for adsorbent materials has a diffraction peak (101) at a diffraction angle of 2θ from 12.55 to 12.90° in the spectrum obtained by X-ray diffraction. The method for separating one or several components selected from the group consisting of CO₂, H₂O, He, Ne, Cl₂, NH₃ and HCl includes separating one or several components selected from the group consisting of CO₂, H₂O, He, Ne, Cl₂, NH₃ and HCl, from a mixture containing two or more gases selected from the group consisting of H₂, N₂, CO and hydrocarbon, by means of using an adsorbent material.

EFFECT: provided is GIS-type zeolite capable of sufficiently adsorbing carbon dioxide and also exhibiting a high selectivity for adsorption of carbon dioxide compared to the value of methane adsorption.
