Progresses in Ammonia: Science, Technology and Membranes: Decomposition considers the membrane technology for improving ammonia decomposition. Various aspects are considered, including the catalytic extraction of hydrogen from ammonia, the recovery of hydrogen from ammonia production processes, the hydrogen production system combined with a membrane reactor from ammonia, highly purified hydrogen production from ammonia for PEM fuel cell, the carbon dioxide capture by aqueous ammonia with membrane, and the Ammonia decomposition in auto-thermal microchannel reactors). Mathematical simulation using the CFD model to investigate the effect of Ammonia decomposition is also discussed.
