Abstract:
The integration of sorption-enhanced steam reforming (SESR) into biorefineries represents an innovative strategy for the decentralized production of renewable hydrogen. This work evaluates the performance of SESR under laboratory conditions using synthetic gas mixtures representative of biomass-derived syngas, with a particular focus on its capacity to adapt to feed and operating variability. Experiments were conducted with varying concentrations of H2, CO, CH4, and CO2, under different operating conditions, including temperature, steam-tocarbon ratio, and space velocity. A Response Surface Methodology (RSM) approach was applied for multivariable optimization. Hydrogen yields above 96% and purities up to 99.8 vol.% were achieved, even under challenging conditions for conventional reforming. The results confirm that SESR is a robust and highly adaptable technology for efficiently valorizing renewable gas streams.
