Patent ID: 8765824

Claim:
A polymeric membrane for separating a hydrocarbon feedstream containing aromatics and alcohol, said membrane comprising a polyether epoxy resin having a reaction product of a polyetheramine and an aliphatic substituted epoxide, which does not contain a heteroatom within three (3) atoms of any epoxide group and which is fully aliphatic, fully aromatic, or a combination of aromatic and aliphatic, wherein the epoxide is divinylbenzene diepoxide, wherein the polyetheramine is selected from the group consisting of Poly(propylene glycol)bis(2-aminopropyl ether)s with an Mn ranging from about 230 to about 4000 and Poly(propylene glycol)-block-poly(ethylene glycol)-block-poly(propylene glycol)bis(2-aminopropyl ether) with an Mn about 600, and wherein said membrane is supported on a porous ceramic substrate having a surface pore size from 0.005 to 0.5 microns.
