TABLETED SORBENT PREPARATION METHOD Russian patent published in 2004 - IPC

Abstract RU 2232046 C1

FIELD: sorbents.

SUBSTANCE: sorbent for adsorption of fluorine-containing gases (uranium or technetium hexafluoride), which can be used in nuclear engineering for separating gas mixtures, is prepared from calcium fluoride with particle size 0.05-0.1 mm. The latter is molded under pressure 32-39 kg/cm² to form tablets, which are characterized by satisfactory values of principal physicochemical properties: specific surface about 28-29 m²/g, porosity about 44-45%, and strength about 75-90 kg/cm² at lower molding pressure values.

EFFECT: facilitated preparation procedure.
