HYDROGEN RELEASE AND RECOVERY FROM ALIPHATIC PRIMARY AMINES OR DI-AMINES

摘要

There is disclosed a process for hydrogen release and chemical storage by dehydrogenating low molecular weight aliphatic amines and di-amines to produce their corresponding nitriles in a reactor system containing a hydrogen fractionation membrane (or sweep gas) to quickly remove any and all hydrogen generated during the dehydrogenation reaction. This disclosure further provides a process for hydrogen recovery using bi- and tri-functional amines that produce corresponding nitriles and high density hydrogen release.
