A modified γ-Al2O3-supported nickel-based Ni/HZSM-5 catalyst prepared by the impregnation method was characterized by physical adsorption of N2, X-ray diffraction, temperature-programmed desorption of ammonia, thermogravimetric analysis, and scanning electron microscopy. The influence of temperature, pressure, flow, and space velocity on the hydrodeoxygenation (HDO) of light components in bio-oil was studied, and a lifespan test was performed on the Ni/HZSM-5-γ-Al2O3 catalyst. The results showed that at a reaction temperature of 380°C, pressure of 2 MPa, flow rate of 380 ml min−1, and mass space velocity of 0.78 h−1, the hydrocarbon content of the upgraded oil was the highest, reaching 89.49%. Long-chain alkanes were the main hydrocarbons in the upgraded oil. The results of a lifespan experiment show the good stability of the Ni/HZSM-5-γ-Al2O3 catalyst in the HDO of bio-oil over 5 h of reaction. The HDO reaction pathway of bio-oil mainly resulted in conversion into long-chain alkanes through a condensation reaction, a decarbonylation/decarboxylation reaction and hydrogenation. This study provides a reference for the preparation of high-quality liquid fuels from biomass. [Correction added on June 18, 2021, after first online publication: 89.47% changed to 89.49%]

Ni/HZSM-5-γ-Al2O3上反应条件对生物油轻组分加氢脱氧制长链烷烃的影响

采用浸渍法制备的改性γ-Al 2 O 3负载镍基Ni/HZSM-5催化剂通过N 2物理吸附、X射线衍射、氨的程序升温脱附、热重分析和扫描表征。电子显微镜。研究了温度、压力、流量和空速对生物油中轻组分加氢脱氧(HDO)的影响,并对Ni/HZSM-5-γ-Al 2 O 3催化剂进行了寿命试验。结果表明,反应温度为380℃,压力为2 MPa,流速为380 ml min -1,质量空速为0.78 h -1,提质油的烃含量最高,达到89.49%。长链烷烃是提质油中的主要碳氢化合物。寿命实验结果表明,Ni/HZSM-5-γ-Al 2 O 3催化剂在生物油的HDO中反应5小时后具有良好的稳定性。生物油的HDO反应途径主要通过缩合反应、脱羰/脱羧反应和加氢转化为长链烷烃。该研究为生物质制备优质液体燃料提供了参考。[2021 年 6 月 18 日更正,首次在线发布后:89.47% 更改为 89.49%]
