Hydrogen can be obtained from biomass pyrolysis liquids by catalytic steam reforming. Catalyst deactivation by coking and the formation of carbon deposits are the major known limitations although the specific causes are unidentified. It is proposed that these limitations could be reduced by selectively reforming specific fractions of the bio-oil. The hydrophobic fraction mainly composed of heavy oligomers can be separated by water extraction as a high-value product. In the current work, the particular interest is on efficient hydrogen production from the residual aqueous fractions. There are certain challenges introduced due to the complexity of these mixtures. An improved understanding ...
