Аннотация: The present paper reviews the processes of separation of microspheres from fly ash and their possible applications for the creation of catalytic supports, adsorbents and catalysts. To isolate magnetic microspheres and cenospheres of stabilized composition, the process flowsheets of concentrate separation, based on the combination oПоказать полностьюf hydro- or aerodynamic and granulometric classification, followed by the separation in magnetic field of different intensity, were developed. Novel materials based on cenospheres of stabilized composition, such as mesoporous microspherical glasses (specific surface area Ssp = 3-50 m2/g), the supported iron oxide systems (Ssp = 50-200 m2/g), and zeolites are described. Spherical zeolites demonstrated good ion exchange properties of in cesium and strontium removal from the technological solutions. The catalytic properties of Fe2O3/cenosphere catalysts and magnetic microspheres in deep oxidation of methane are discussed.
