Abstract

A regeneratable adsorber for adsorbing adsorbable contaminates from a fluid stream containing same is disclosed. The adsorber includes an adsorber housing in which there is a fluid stream inlet and a fluid stream outlet. The adsorber also includes a plurality of adsorber chambers which are arranged in an indexable wheel configuration. Each chamber includes an electrically conductive adsorbent, such as a monolithic activated carbon, a set of electrical conductors in contact with the adsorbent, and an inlet and outlet. A chamber is either in contact with a source of contaminate fluid or a desorbent fluid used to regenerate the adsorber. The adsorber includes selectively indexed chambers for adsorption or desorption to provide continuous contaminate adsorption and regeneration.
