A new paper by Renée Ripken and Séverine le Gac of the AMBER team, in collaboration with Jan Meuldijk of the Technical University of Eindhoven, can now be found online in ChemSusChem.
The work evaluates the phase state, temperature-dependent enthalpy, and Gibbs free energy for APR (Aqueous Phase Reforming) of several biomass model substrates. The phase equilibirum study demonstrates that, under typical APR reaction conditions, reaction mixtures are in the liquid phase, implying that the Water Gas Shift (WGS) reaction, a key step in APR, should also be modeled in the liquid phase. This results in an endothermic instead of an exothermic reaction enthalpy, which has the important implication that the WGS reaction in APR has a comparable energy demand as WGS has in steam reforming.
