Abstract

"ADSORVENTE DE ZEóLITO, E, PROCESSO PARA SELETIVAMENTE ADSORVER NITROGêNIO DE UMA MISTURA GASOSA". Adsorventes de zeólito trocador de cátion monovalente e/ou divalente, tais como zeólitos zinco-substituídos, para uso na separação de nitrogênio de um gás, tal como ar, e um processo para utilização dos adsorventes em um ciclo de adsorção com oscilação de pressão para produzir económica e efetivamente nitrogênio a partir de ar.
