Composite membranes and methods of use |
| abstract |
The use of an asymmetric composite membrane for selectively pervaporating alcohol from an alcohol and gasoline feed mixture. The asymmetric composite membrane includes a porous substrate comprising opposite first and second major surfaces, and a plurality of pores. A pore-filling polymer is disposed in at least some of the pores so as to form a layer coating all of the first major surface of the porous substrate and having a thickness within the porous substrate, with the amount of the pore-filling polymer at or adjacent to the first major surface being greater than the amount of the pore-filling polymer at or adjacent to the second major surface. The starting materials for the pore-filling polymer include ethylenically unsaturated monomers and/or oligomers The polymer is more permeable to alcohol than gasoline but not soluble in alcohol or gasoline. |
