Polymeric membranes cardopolymers

C02-selective polymeric membranes (cardopolymers, FSCs), CMS, mixed matrix, or biomimetic materials are potential membrane materials for this application. The purified methane can then be compressed to 300 bar and stored in tanks for fuel in the transport sector or for conversion to methanol used for FCs. 

If the gas is cooled down, a C02-selective polymeric membrane may be used (cardopolymers and carrier membranes are especially interesting. Problem compression of exhaust gas may be needed see Section 4.3.1)...
