CoMoS/ZrO2催化4-甲基苯酚加氢脱氧中C−O键的选择性断裂
Selective breaking of C?O bonds in hydrodeoxygenation of 4-methylphenol over CoMoS/ZrO2
摘要
Abstract
CoMoS/ZrO2 catalysts with different Co-Mo atomic ratios (0.25, 0.30, 0.35, 0.40 and 0.45) and Co-Mo loading amounts (2.35％, 4.36％, 7.48％ and 10.79％) were prepared by incipient wetness impregnation. These catalysts were characterized by X-ray diffraction (XRD), temperature-programmed reduction (H2-TPR), nitrogen adsorption/desorption and X-ray photoelectron spectroscopy (XPS). 4-methylphenol was used as model compound for hydrodeoxygenation reaction. The result showed that when the atomic ratio of Co-Mo (Co/Co + Mo) was 0.30 and the Mo loading amount was 4.36％, the highest hydrogenation activity was observed. The conversion of 4-methylphenol was up to 99.86％ and the selectivity of main product toluene reached to 87.85％. The formation of CoMoO4 was unfavourable to the formation of toluene. An appropriate interaction between Co-Mo and ZrO2 was required.关键词
