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 of 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) is regenerated utilizing a low-voltage current from power supply (22) that is caused to pass through filter media (7).
