It is experimentally demonstrated that either increasing the thickness of the membrane selective layer or using a small purification unit in the permeate of the membranes, ultra-pure hydrogen can be produced. Specifically, the results show that increasing the membrane thickness above 6 μm ultra-pure hydrogen can be obtained at pressures below 5 bar. A cheaper solution, however, consists in the use of an adsorption bed downstream the membrane reactor. In this way, ultra-pure hydrogen can be achieved with higher reactor pressures, lower temperatures and thinner membranes, which result in lower reactor costs. A possible process diagram is also reported showing that the regeneration of the adsorption bed can be done by exploiting the heat available in the system and thus introducing no additional heat sources.111097723enginfo:eu-repo/semantics/openAccessUltra-pure hydrogen production via ammonia decomposition in a catalytic membrane reactorjournal article10.1016/j.ijhydene.2022.04.240Ammonia decompositionMembrane reactorHydrogen storageHydrogen separationHydrogen purificationAmmonia decompositionMembrane reactorHydrogen storageHydrogen separationHydrogen purificationRenewable Energy, Sustainability and the EnvironmentFuel TechnologyCondensed Matter PhysicsEnergy Engineering and Power TechnologySDG 7 - Affordable and Clean EnergyProject IDinfo:eu-repo/grantAgreement/EC/H2020/862482/EU/Advanced materials and Reactors for ENergy storage tHrough Ammonia/ARENHAinfo:eu-repo/grantAgreement/EC/H2020/862482/EU/Advanced materials and Reactors for ENergy storage tHrough Ammonia/ARENHAFunding InfoThis project receives support from the European Union’s Horizon 2020 research and nnovation under grant agreement No. 862482 (ARENHA project).This project receives support from the European Union’s Horizon 2020 research and nnovation under grant agreement No. 862482 (ARENHA project).http://www.scopus.com/inward/record.url?scp=85130574206&partnerID=8YFLogxK
