Energy and exergy analysis of hydrogen production from ammonia decomposition systems using non-thermal plasma

In the current study, energy and exergy efficiencies of three hydrogen production systems from ammonia decomposition using dielectric barrier discharge plasma (DBD) were comparatively evaluated. The gas was separated in a cylindrical membrane reactor (PMR) Pd–Cu40% with thickness 20 μm. pre-catalytic (CR) is added to second system (CR-PMR), additionally, CR filled catalytic material type 2%Ru/Al2O3 temperature raised 450 °C. Furthermore, zeolite SA-600 A PMR third H2 enhance permeation through Pd–Cu membrane. rate enhanced by combining (CR-CPMR). Moreover, maximum obtained rates 2.66, 81.6, 96.6% PMR, CR-PMR, CR-CPMR or respectively. Also, it observed that efficiency increased adding system, while, values all still low due effect irreversibility. Additionally, 0.8, 16.1, 44.1%, while 0.156, 4.91, 6.344% for CR-CPMR, destruction NH3 high although modified systems. depletion factor feeding flow sustainability index decreased at same rates. seen results only higher than other high.
