system is reported
for characterization of hydroprocessing reactions of biomass-derived
compounds. All of the reactants are liquids. Data are presented for
conversion of guaiacol catalyzed by Pt/MgO and, in much less detail,
CoMo/Al2O3. The data demonstrate the advantages
of high pressure in such reactions, determining a pseudo-first-order
rate constant for guaiacol conversion at 523 K and 69 bar of approximately
55 L of organic reactant solution (g of catalyst)–1 h–1. This value is 2 orders of magnitude greater
than that observed at 573 K and 1.4 bar.
