The effects of Ce and W addition to the Pt/TiO2 and Ru/ZrO2 catalysts for the hydrodeoxygenation of guaiacol have been studied. The catalysts were characterized using XRD, BET, NH3-TPD, O2-TPD, H2-TPR, CO-chemisorption, and TPO. The reaction results exhibited that the Ce addition significantly improved the catalytic activity of the Pt/TiO2. The conversion of guaiacol was improved by two-fold with the addition of Ce. The presence of Ce in the Pt/TiO2 catalysts could stabilize the active sites of Pt on the support, and further improved the catalytic activity of Pt/TiO2. Similarly, the W addition increased the catalytic activity of Ru/ZrO2 catalysts, which was attributed to the increase of metal dispersion on the supports. |
