Gasification of Biomass to Generate Renewable Hydrogen Conventional and New Approaches
State of the art of Hydrogen generation is the steam reforming process, typically applied in combination with partial oxidation to supply heat for the reforming reactions. For solid fuels in most cases oxygen blown gasification is applied to crack the carbon. However, for biomass fuels this technology, which is typically applied with some 100 MW, is too expensive. Therefore there is considerable R&D effort to develop new technologies in order to convert biomass in cheap hydrogen. This paper presents a new process called Absorption enhanced reforming which combines gasification, reforming and a preliminary gas dean up in one single reactor. The new process applies in-situ CO2 absorption pushing the equilibrium towards hydrogen. First experiments show that in a fluidized bed reactor H2 concentrations of up to 75％ can be achieved.
