    Abstract: 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).

    Abstract: A mixed matrix membrane for separating gas components from a mixture of gas components is disclosed. The membrane comprises a continuous phase polymer with inorganic porous particles, preferably molecular sieves, interspersed in the polymer. The polymer has a C0 2 /CH 4 selectivity of at least (20) and the porous particles have a mesoporosity of at least 0.1 cc STP/g. The mixed matrix membrane exhibits an increase in permeability of least 30% with any decrease in selectivity being no more than 10% relative to a membrane 10 made of the neat polymer. The porous particles may include, but are not limited to, molecular sieves such as CVX-7 and SSZ-13, and/or other molecular sieves having the required mesoporosity. A method for making the mixed matrix membrane is also described. Further, a method is disclosed for separating gas components from a mixture of gas components using the mixed matrix membrane with mesoporous particles.
