Abstract

"PROCESSOS PARA FORMAR E PREPARAR UMA MEMBRANAMETáLICA PERMEáVEL A HIDROGêNIO, E, MEMBRANAMETáLICA PERMEáVEL A HIDROGêNIO". Uma membranametálica permeável a hidrogênio (30) com maior fluxo de hidrogênioem comparação com membranas metálicas convencionais éproduzida por pelo menos uma etapa de causticação, na qual umvolume controlado de causticante é usado para removerseletivamente material de superfícies (32, 34) da membrana (30).Sem sacrificar a seletividade da membrana, a membrana (30)permite uma maior vazão de hidrogênio purificado. Os orifícios (60)ou outros defeitos na membrana (30) podem ser reparados pelaadição de um metal selante.
