摘要
木质素是一种芳香族聚合物，具有生产高附加值化学品的前景。本研究以 Ni/xCeO2-yAl2O3 为催化剂，甲酸为氢源，在水热反应釜中于 240 °C 下对碱性木质素进行了 8 小时的氢解反应。结果表明，与单一氧化物支撑的 Ni 催化剂相比，Ni/xCeO2-yAl2O3 复合支撑的催化剂具有更好的催化解聚性能和更高的生物油产率。其中，Ni/1CeO2-3Al2O3 的催化活性最为突出，生物油产率为 52.77 wt%，酚类化合物产率为 7.21 wt%。
Catalytic hydrogenolysis of lignin over Ni/CeO2-Al2O3 catalysts with formic acid as hydrogen source
Lignin is an aromatic polymer with prospects for producing high value-added chemicals. In this study, hydrogenolysis of alkaline lignin was carried out at 240 °C for 8 h in a hydrothermal kettle using Ni/xCeO2-yAl2O3 as catalyst and formic acid as hydrogen source. Compared with Ni catalysts supported by single oxides, the results showed that Ni/xCeO2-yAl2O3 composite-supported catalysts exhibited better catalytic depolymerization performance with higher bio-oil yields. Among them, Ni/1CeO2–3Al2O3 exhibited the most outstanding catalytic activity, with a bio-oil yield of 52.77 wt% and a phenolic compound yield of 7.21 wt%.
