Abstract
Using H2 as a reductant, catalytic hydrodeoxygenation (HDO) is typically used for upgrading bio-oils, generally produced from thermal degradation of lignin. In our recent prior work, methane was used to deoxygenate guaiacol over the Pt–Bi catalyst and was found to exhibit as good deoxygenation performance as hydrogen. In the present work, using methane as a reductant, detailed reaction pathways and kinetics of guaiacol deoxygenation are studied using differential and integral operating conditions. Kinetic parameters including rate constants and activation energies are determined for each individual reaction step. The model predicted values match experimental data well. Results from the present work are discussed and compared with the literature values. The present work provides a practical novel approach for bio-oil upgrading using methane as a reductant instead of hydrogen.
