Abstract

An absorbent powder, e.g., activated charcoal or alumina, ion-exchange resin etc., is held between two or more layers of fibrous, woven, open-cellular, or sintered sheets (e.g., of cellulose, synthetic fibre, plastic foam etc.); to form a filter material, which may be used continuously as a band, or as an endless belt (with regeneration); or e.g., wound into a spiral, as a cylindrical cartride, with an axial inlet and peripheral outlet. The material may be reinforced, e.g., by welding or quilting; it is adaptable for use as a continuous absorber, more compact and lower in cost than fluidised bed types, and combining the filtering function.
