Abstract

1. Способ получения порошковой формы сорбента, отличающийся тем, что гель метилкремниевой кислоты подвергают дополнительной термической обработке при температуре от приблизительно 120°C и до приблизительно 360°C до содержания остаточной влаги не более 2% с последующей механической обработкой на измельчителе до получения содержащихся в продукте частиц до заданного уровня, предпочтительно до уровня 10-200 мкм, обеспечивающих насыпную плотность не менее 0,319 г/мл.2. Способ применения адсорбента по п 1, отличающийся тем, что порошкообразный сорбент капсулируют.1. The method of obtaining a powder form of the sorbent, characterized in that the gel of methylsilicic acid is subjected to additional heat treatment at a temperature of from about 120 ° C to about 360 ° C to a residual moisture content of not more than 2%, followed by mechanical processing on a grinder to obtain contained in particle product to a predetermined level, preferably to a level of 10-200 microns, providing a bulk density of at least 0.319 g / ml. 2. The method of using the adsorbent according to claim 1, characterized in that the powdered sorbent is encapsulated.
