An autothermal sorption-enhanced steam methane reforming in a packed-bed reactor for production of high-purity hydrogen was studied by means of 1D numerical model. The reactor utilises a CaO/CuO/Al2O3(NiO) catalyst. This process is characterised by a number of challenges, such as the choice of the operating conditions to ensure both a production of high-purity H2 stream and an autothermal sorbent regeneration stage. This paper addresses these challenges through numerical simulation. The results for the system cyclically operated in a packed-bed showed a methane conversion of 95%, and a hydrogen yield and selectivity around 3molH2·molCH4-1 and 90%, respectively.

Abstract
An autothermal sorption-enhanced steam methane reforming in a packed-bed reactor for production of high-purity hydrogen was studied by means of 1D numerical model. The reactor utilises a CaO/CuO/Al2O3(NiO) catalyst. This process is characterised by a number of challenges, such as the choice of the operating conditions to ensure both a production of high-purity H2 stream and an autothermal sorbent regeneration stage. This paper addresses these challenges through numerical simulation. The results for the system cyclically operated in a packed-bed showed a methane conversion of 95%, and a hydrogen yield and selectivity around 3molH2·molCH4-1 and 90%, respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
