CARBON FIBER COMPOSITE MOLECULAR SIEVE ELECTRICALLY REGENERABLE AIR FILTER MEDIA

摘要

An electrically regenerable gas filter system includes a carbon fiber composite molecular sieve (CFCMS) filter medium (7) for separation and purification, or catalytic processing of fluids. Filter medium (7) is made o f carbon fibers rigidly bonded to form an open, permeable, rigid monolith capable of being formed to near-net-shape. A separate medium-efficiency pre- filter (5) removes particulate from a supply airstream before the airstream passes through the CFCMS filter (7) to sorb gaseous air polutants. The airstream is then recirculated to a space. When saturated, CFCMS media (7) i s regenerated utilizing a low-voltage current from power supply (22) that is caused to pass through filter media (7).
