An adsorption/desorption unit includes a hollow enclosure containing one or more elongate hollow elements of activated carbon fiber cloth (ACFC) of appropriate length to cross sectional area to provide suitable electrical resistance for heating. The elements conduct electrical current to heat to a temperature that permits selective adsorption of a gas stream constituent and subsequent desorption to recover sorbate. An enclosure houses the ACFC elements and is arranged to direct gas stream flow through the elements and into and out of the enclosure via gas ports. The ability to heat the elements to a desired temperature by electrical current flow allows for straightforward implementation of selective adsorption. After an adsorption step, altering the temperature of the element or elements enables desorption. In a particularly preferred embodiment, the enclosure with the element also includes a liquid condensate outlet and liquid sorbate is directly recovered as liquid from the same unit used for adsorption and desorption.

1. An adsorption and recovery method for an adsorption unit including at least one activated carbon fiber element, the method comprising steps of:heating an activated carbon fiber element through electrical current flow, the activated carbon fiber element being configured to exhibit sufficient electrical resistance for heating; directing a gas flow to penetrate the activated carbon fiber element when the activated carbon fiber element has been heated to selectively adsorb at least one constituent of the gas flow; desorbing an adsorbed constituent by controlling activated carbon fiber temperature through electrical current flow to a temperature for desorption in the presence of an inert gas flow; controlling the inert gas flow to permit condensation of a desorbed constituent on an inner surface of an enclosure housing the activated carbon fiber elements; recovering condensate that comprises desorbed constituents in liquid phase from the enclosure.
