Process for separation of the constituents of a mixture in the gas phase using a composite membrane

摘要

A mixture of at least two constituents A and B is submitted to selective separation across a selective membrane. The membrane comprises an active layer comprising particles of a selective solid (5) dispersed in a continuous non-porous and non-elastomeric polymer phase (4) and a porous support (6). The thickness of the active layer is less than 100 micrometers, advantageously less than 20 micrometers.
