1. A method for separating one or more targeted constituents from a fluid mixture comprising the steps of:
- flowing the fluid mixture through a rigid, electrically conductive adsorbent member having an affinity for the targeted constituents, the adsorbent member further comprising an activated carbon fiber composite material consisting essentially of a multiplicity of porous carbon fibers bonded with a carbonizable organic binder to form an open, permeable structure, the composite defining a porosity in a range of approximately 82-86%;
adsorbed molecules of the targeted constituents being adsorbed on the adsorbent member; and
applying a voltage to the adsorbent member, the voltage imparting a current flow which causes the adsorbed molecules of the targeted constituents to be desorbed from the adsorbent member.

Abstract
A method and apparatus for separating one constituent, especially carbon dioxide, from a fluid mixture, such as natural gas. The fluid mixture flows through an adsorbent member having an affinity for molecules of the one constituent, the molecules being adsorbed on the adsorbent member. A voltage is applied to the adsorbent member, the voltage imparting a current flow which causes the molecules of the one constituent to be desorbed from the adsorbent member.
