This study is focused on fast hydropyrolysis of biomass followed by upgradation of pyrolysates over γ-alumina-supported tungsten carbide catalyst (W₂C/γ-Al₂O₃). The catalyst was prepared by wet-impregnation followed by carburization, and was characterized by various techniques. Catalytic fast-hydropyrolysis experiments were performed at 500 °C in an analytical pyrolyzer coupled with gas chromatograph-mass spectrometer using pine-wood, cellulose and lignin as the feedstocks. W₂C/γ-Al₂O₃ is proved to be an efficient hydrodeoxygenation catalyst producing aromatic and aliphatic hydrocarbons at 82% and 15% selectivities, respectively. Further, the activity of W₂C/γ-Al₂O₃ catalyst is better than γ-Al₂O₃ and WO₃/γ-Al₂O₃ in terms of both hydrocarbon selectivity and biomass conversion.

这项研究的重点是生物质的快速加氢然后用γ-氧化铝负载的碳化钨催化剂热解的升级换代（W ₂ C /γ-Al系₂ ö ₃）。通过湿浸渍然后渗碳来制备催化剂，并通过各种技术对其进行表征。催化快速加氢热解实验是在分析型热解仪和气相色谱-质谱联用的500℃下进行的，其中使用松木，纤维素和木质素作为原料。w ^ ₂ C /γ-Al系₂ ö ₃被证明是产生在82％的芳族和脂族烃和15层％的选择性的有效加氢脱氧催化剂，分别。此外，W ₂的活性C /γ-Al系₂ ö ₃催化剂比的γ-Al更好₂ ö ₃和WO ₃ /γ-Al系₂ ö ₃在这两个烃的选择性和生物质转化的条款。
