Steam reforming of the bio-oil aqueous fraction in a fluidized bed reactor with in situ CO2 capture

The effect of CO2 capture in the hydrogen production by steam reforming of the bio-oil aqueous fraction was studied. The reforming and cracking activity of the adsorbent (dolomite) and relationship between these reactions and those corresponding to the catalyst (reforming and WGS) were considered. T...
