Green Hydrogen Recovery from Natural Gas Grids by Vacuum Pressure Swing Adsorption
Zafanelli, Lucas F.A.S.; Aly, Ezzeldin; Henrique, Adriano; Rodrigues, Alírio; Mouchaham, Georges; Silva, José A.C.This study focuses on the development of a conceptual vacuum pressure swing adsorption process (VPSA) for green hydrogen (GH) recovery from natural gas grids (NGGs). Accordingly, the kinetics-based separation of H-2 from NGG was achieved by using a commercial carbon molecular sieve (CMS-3K-172) adsorbent. To develop the VPSA cycle, the CMS-3K-172 was characterized, single- and multicomponent breakthrough curves...
Novel vacuum pressure swing adsorption for green hydrogen recovery from natural...
Zafanelli, Lucas F.A.S.; Aly, Ezzeldin; Henrique, Adriano; Rodrigues, Alírio; Mouchaham, Georges; Silva, José A.C.This work shows for the first time that an adsorbent that adsorbs preferentially H2 and blocks CH4 from entering its pores can be useful to enrich H2 from a low feed concentration. Moreover, this work provides insights for developing new materials with the same CMS characteristics but with higher H2 capacity, which could be beneficial to improve the VPSA process. In conclusion, the developed VPSA process is use...

Zafanelli, Lucas F.A.S.; Henrique, Adriano; Aly, Ezzeldin; Rodrigues, Alírio; Mouchaham, Georges; Silva, José A.C.Transitioning to renewable energy sources is crucial to mitigating climate change. In this scenario, green hydrogen (GH) is considered a promising energy carrier due to its high calorific value, versatility in applications, clean combustion, and potential for local generation in abundance. As interest in GH grows, developing its distribution chain becomes crucial in facilitating its widespread use. The co-trans...
