Description
Summary:Second generation biofuels are produced in the bioliq® process at the Karlsruhe Institute of Technology via gasification of pyrolysis oil and synthesis of gasoline from the emerging synthesis gas. An alternative strategy is the direct upgrading of the pyrolysis oil by hydrodeoxygenation (HDO). The present study reports on the HDO of guaiacol as one of the phenolic compounds strongly abundant in such mixtures. Special focus was laid on the solvent influence using Pt‐based catalysts. Higher HDO ability was seen using nonpolar solvents and acidic supports. Characterization of the catalysts before and after the test showed that the solvent did not only influence the reactivity, but also the catalyst stability. Guaiacol is a phenolic compound strongly abundant in pyrolysis oil. The influence of the solvent has been investigated on the hydrodeoxygenation of guaiacol over Pt‐based catalysts. Characterization of the catalysts before and after test showed that the solvent had not only a direct influence on the reactivity but also the catalyst stability.
