High temperature resistant epoxy resins for producing hollow fiber membrane modules for high temperature gas separation applications

A hollow fiber membrane module comprising an epoxy resin prepared from comprising an aromatic epoxy, a diluent, and an aromatic diamine, wherein said aromatic epoxy is represented by formula (I):

• wherein n is a positive integer from 1 to 10;
• wherein said diluent is selected from the group consisting of an epoxy represented by formula (II), an epoxy represented by formula (III), and a mixture thereof;
• wherein m is a positive integer from 2 to 10;
• and
• wherein said aromatic diamine is represented by formula (IV):
• wherein the weight ratio of said aromatic epoxy to said diluent is in a range of about 10:1 to 35:1.

A process for separating at least one gas from a mixture of gases using hollow fiber membrane modules comprising a bundle of multiple high performance hollow fiber membranes and a tube sheet formed by a high temperature resistant cured epoxy resin wherein said high temperature resistant cured epoxy resin is used to fix and bound said bundle of multiple high performance hollow fiber membranes, the process comprising:

• (a) providing the hollow fiber membrane module comprising a bundle of multiple high performance hollow fiber membranes which are permeable to said at least one gas and a tube sheet formed by the high temperature resistant cured epoxy resin comprising an aromatic epoxy, a diluent, and an aromatic diamine, wherein said aromatic epoxy is represented by formula (I):
• wherein n is a positive integer from 1 to 10;
• wherein said diluent is selected from the group consisting of an epoxy represented by formula (II), an epoxy represented by formula (III), and a mixture thereof;
• wherein m is a positive integer from 2 to 10;
• and
• wherein said aromatic diamine is represented by formula (IV):
• wherein the weight ratio of said aromatic epoxy to said diluent is in a range of about 10:1 to 35:1 and that is used to fix and bound said bundle of multiple high performance hollow fiber membranes;
• (b) contacting the mixture on one side of said hollow fiber membrane module to cause said at least one gas to permeate said hollow fiber membranes;
• and
• (c) removing from the opposite side of said hollow fiber membrane module a permeate gas composition comprising a portion of said at least one gas which permeated said hollow fiber membranes.
