FIELD: chemical industry. SUBSTANCE: apparatus has one or several adsorption tube-type members, that represent a set of cylindrical blocks of contracted fine or ultrafine basalt fibres preliminary treated by mineral acid. Blocks are located one over another on perforated pipe. Fibrous adsorbent and structure of apparatus allow under low gas-dynamic resistance to achieve higher dynamic sorption capacity, as compared with apparatus with loose layer of silica gel. EFFECT: apparatus is used in chemical industry for gasses purification and / or drying. 3 cl, 2 dwg
