The hydrodeoxygenation of pure phenol in hexane solution and of catalytic biomass fast pyrolysis oil (bio-oil) over 10 %Ni/ZrO₂ and 10 %Ni/WO₃-ZrO₂ catalysts was investigated in the present study, at relatively mild conditions (ca. 50−250 °C, 30 bar H₂) in a continuous flow high-pressure fixed bed reactor. The catalysts were characterized for their structural, porosity, redox and acidic/basic properties which were used to rationalize the observed catalytic performance. The 10 %Ni/ZrO₂ catalyst was very active and selective towards cyclohexanol in the phenol HDO experiments (100 % conversion and selectivity at 110 °C) but the enhanced acidity offered by the addition WO₃ in ZrO₂ was necessary to succeed a complete hydrodeoxygenation of phenol to cyclohexane at the low temperature of 150 °C with the 10 %Ni/WO₃-ZrO₂ catalyst. This catalyst was also proven very active in the hydrodeoxygenation of the catalytic bio-oil which consisted of mono-aromatics (i.e. alkyl-benzenes) and PAHs (mainly naphthalenes and indenes), and fewer oxygenated compounds (i.e. alkyl-phenols and benzofurans), providing a product oil containing mainly alkyl-cycloalkanes and fewer alkyl-benzenes, at the mild conditions of 210 °C and 30 bar H₂.

本研究研究了在相对温和的条件下（10％Ni / ZrO ₂和10％Ni / WO ₃ -ZrO ₂催化剂上的纯苯酚和己烷中的催化生物质快速热解油（bio-oil）的加氢脱氧（约50-250°C，30 bar H ₂）在连续流高压固定床反应器中。对催化剂的结构，孔隙率，氧化还原和酸性/碱性性质进行了表征，这些催化剂用于合理化所观察到的催化性能。10％Ni / ZrO ₂催化剂在苯酚HDO实验中具有很高的活性，对环己醇具有选择性（在110°C时100％的转化率和选择性），但在ZrO中添加WO _3可提高酸度。₂是必要的，在150℃的低温下与10％的Ni /成功苯酚的完整加氢脱氧，以环己烷WO ₃ -ZrO ₂催化剂。事实证明，这种催化剂在催化生物油的加氢脱氧中非常有活性，该生物油由单芳香族化合物（即烷基苯）和PAH（主要是萘和茚基）和较少的含氧化合物（即烷基酚和苯并呋喃）组成，在210°C和30 bar H ₂的温和条件下提供主要包含烷基环烷烃和较少烷基苯的产物油。
