We aim to develop high–performance carbon hollow fiber membranes derived from sulfonated poly(phenylene oxide) (SPPO) for hydrogen separation from light hydrocarbons such as ethylene and propylene. After optimization of the preparation conditions, the high hydrogen selectivity was successfully obtained. In addition, we also improved the hydrogen permeance by the addition of cross–linkers into the precursor polymer and achieved the targeted value for hydrogen/propylene mixed gas separation.
