<p>Secondary streams in biorefineries need to be valorized to improve the economic and environmental sustainability<br>
of the plants. Representative model compounds of the water fraction from the hydrothermal liquefaction<br>
(HTL) of biomass were subjected to aqueous phase reforming (APR) to produce hydrogen. Carboxylic and bicarboxylic<br>
acids, hydroxyacids, alcohols, cycloketones and aromatics were identified as model compounds and<br>
tested for APR. The tests were performed with a Pt/C catalyst and the influence of the carbon concentration<br>
(0.3–1.8 wt. C%) was investigated. Typically, the increase of the concentration negatively affected the conversion<br>
of the feed toward gaseous products, without influencing the selectivity toward hydrogen production. A<br>
synthetic ternary mixture (glycolic acid, acetic acid, lactic acid) was subjected to APR to evaluate any differences<br>
in performance compared to the tests with single compounds. Indeed, glycolic acid reacted faster in the mixture<br>
than in the corresponding single compound test, while acetic acid remained almost unconverted. The influence<br>
of the reaction time, temperature and carbon concentration was also evaluated. Finally, residual water resulting<br>
from the HTL of a lignin-rich stream originating from an industrial-scale lignocellulosic ethanol process was<br>
tested for the first time, after a thorough characterization. In this framework, the stability of the catalyst was<br>
studied and found to be correlated to the presence of aromatics in the aqueous feedstock. For this reason, the<br>
influence of an extraction procedure for the selective removal of these compounds was explored, leading to an<br>
improvement in the APR performance.</p>
