This paper addresses the separation of hydrogen using Carbon Molecular Sieves Membranes (CMSM), which show an attractive combination of high permeability, selectivity and stability. Supported CMSM containing various amounts of aluminium have been prepared from novolac and aluminium acetyl acetonate (Al(acac)3) as carbon and alumina precursors. The thickness of the CMSM layers depend on the content of Al(acac)3 in the dipping solution, which also has influence in the pore size and pore size distribution of the membranes. The permeation properties of the membranes against the Al content in the membrane follows a volcano shape, where the membrane containing 4 wt (%) of Al(acac)3 has the best properties and was stable during 720 h for hydrogen at 150 °C and 6 bar pressure difference. All the CMSM have permeation properties well above the Robeson Upper limit.101844834enginfo:eu-repo/semantics/openAccessjournal article10.1016/j.ijhydene.2022.02.198Carbon membranesHydrogen separationNovolac resinSupported carbon membranesCarbon membranesHydrogen separationNovolac resinSupported carbon membranesRenewable Energy, Sustainability and the EnvironmentFuel TechnologyCondensed Matter PhysicsEnergy Engineering and Power TechnologyFunding InfoThe research has been carried out within the TTW Perspectief Programme “Microsync” project number P16-10.The research has been carried out within the TTW Perspectief Programme “Microsync” project number P16-10.http://www.scopus.com/inward/record.url?scp=85126706292&partnerID=8YFLogxK
