Single-Stage Production of Highly Concentrated Hydrogen from Biomass-Derived Syngas

Running out of steam: Integrating in situ removal of CO2 with the steam reforming and water–gas shift reactions of biomass-derived syngas containing alkanes and alkenes in a single reaction unit is demonstrated as an efficient approach to simplify production steps from biomass to hydrogen in gasification plants. The integrated sorption enhanced reaction yields hydrogen greater than 97 mol % at low temperatures of 500–575 °C and a steam to carbon ratio as low as 1.4.
