Abstract

A suspension of inorganic particles, a copolymer comprising soft segments and hard segments, and a solvent may be extruded through a spinnerette to produce inorganic/organic composite hollow precursor fibers. The precursor fibers may be sintered. The fibers may be utilized in a gas separation module for separation of a gas mixture or production of syngas. The fibers may be installed in the gas separation module after sintering or they may be sintered after installation.
