Adsorbent filled porous fibers that can be formed into a module to enable controlled contact with a feed stream

Abstract

Georgia Tech inventors have developed methods using absorbent fiber composition. The goal of absorption processes is the separation of fluid mixtures. This invention focuses on a matrix of absorbent fibers. Each fiber is comprised of an adsorbent material within a controlled porosity matrix. These adsorbent-filled porous fibers can be formed into a module to enable controlled contact with a feed stream. As the feed stream is pushed through the modules, a cycle for the feed stream is created giving the stream cyclic exposure to the fibers. To achieve improved separation performance of the stream, the porous fibers permit favorable decoupling of the adsorption kinetics through the pressurization/depressurization dynamic process that occurs within the module. This is a novel approach that overcomes technical problems associated with the “binderless” small particle approach as well as with monolith module creation.
