5 wt% ruthenium-loaded Zeolite-β is found to be efficient for hydrotreating the lignin model compound, at 170 °C under 10 bar hydrogen pressure to give methyl cyclohexane. The catalyst has a bifunctional nature in which the redox properties of ruthenium and the strong acidic nature of Zeolite-β are instrumental in the hydrotreating of -cresol. The well-dispersed metallic ruthenium on Zeolite-β, as evident from TEM and EDS mapping analysis, is responsible for the potential activity. The activity was retained even after six cycles and was also found to have potential for hydrotreating various other functional substrates.

间甲酚的加氢处理：一种木质素衍生的酚类化合物，使用钌修饰的沸石-β

发现 5 wt% 负载钌的沸石-β 可有效地在 170 °C、10 bar 氢气压力下对木质素模型化合物进行加氢处理，得到甲基环己烷。该催化剂具有双功能，其中钌的氧化还原性质和沸石-β的强酸性性质有助于对甲酚的加氢处理。从 TEM 和 EDS 图分析可以看出，Zeolite-β 上分散良好的金属钌是潜在活性的原因。即使在六个循环后，该活性仍然保留，并且还被发现具有加氢处理各种其他功能底物的潜力。
