Abstract

Poly(4-methyl-2-pentyne) (PMP)/TiO₂ hybrid nanocomposite membranes have been investigated for natural gas conditioning. Tailor-made PMP with 35% cis-content was identified as an attractive material to prepare nanocomposite membranes; it presented good stability towards organic vapors and optimal properties for butane/methane separation. The PMP/TiO₂ hybrid nanocomposite membranes presented an improvement of butane permeability and butane/methane selectivity. The addition of TiO₂ nanoparticles to the PMP enhanced the selectivity more effectively than fumed-silica, and it is attractively higher than those currently reported in the open literature.
